build: fix detection of next rc version

Only Require either matching UID & GID OR matching Names.

If the 2 devices have a different Name => UID mapping, they can never be
totaly equal. Therefore when syncing we try matching the Name and fall
back to the UID. However when scanning for changes we currently require
both the Name & UID to match. This leads to forever having out of sync
files back and forth, or local additions when receive only.

This patch does not change the sending behavoir. It only change what we
decide is equal for exisiting files with mismapped Name => UID,

The added testcases show the change: Test 1,5,6 are the same as current.
Test 2,3 Are what change with this patch (from false to true). Test 4 is
a subset of test 2 they is currently special cased as true, which does
not chnage.

+# Contributor Covenant Code of Conduct
+
+## Our Pledge
+
+In the interest of fostering an open and welcoming environment, we as
+contributors and maintainers pledge to making participation in our project and
+our community a harassment-free experience for everyone, regardless of age, body
+size, disability, ethnicity, gender identity and expression, level of experience,
+education, socio-economic status, nationality, personal appearance, race,
+religion, or sexual identity and orientation.
+
+## Our Standards
+
+Examples of behavior that contributes to creating a positive environment
+include:
+
+* Using welcoming and inclusive language
+* Being respectful of differing viewpoints and experiences
+* Gracefully accepting constructive criticism
+* Focusing on what is best for the community
+* Showing empathy towards other community members
+
+Examples of unacceptable behavior by participants include:
+
+* The use of sexualized language or imagery and unwelcome sexual attention or
+  advances
+* Trolling, insulting/derogatory comments, and personal or political attacks
+* Public or private harassment
+* Publishing others' private information, such as a physical or electronic
+  address, without explicit permission
+* Other conduct which could reasonably be considered inappropriate in a
+  professional setting
+
+## Our Responsibilities
+
+Project maintainers are responsible for clarifying the standards of acceptable
+behavior and are expected to take appropriate and fair corrective action in
+response to any instances of unacceptable behavior.
+
+Project maintainers have the right and responsibility to remove, edit, or
+reject comments, commits, code, wiki edits, issues, and other contributions
+that are not aligned to this Code of Conduct, or to ban temporarily or
+permanently any contributor for other behaviors that they deem inappropriate,
+threatening, offensive, or harmful.
+
+## Scope
+
+This Code of Conduct applies both within project spaces and in public spaces
+when an individual is representing the project or its community. Examples of
+representing a project or community include using an official project e-mail
+address, posting via an official social media account, or acting as an appointed
+representative at an online or offline event. Representation of a project may be
+further defined and clarified by project maintainers.
+
+## Enforcement
+
+Instances of abusive, harassing, or otherwise unacceptable behavior may be
+reported by contacting the project team at security@syncthing.net. All
+complaints will be reviewed and investigated and will result in a response that
+is deemed necessary and appropriate to the circumstances. The project team is
+obligated to maintain confidentiality with regard to the reporter of an incident.
+Further details of specific enforcement policies may be posted separately.
+
+Project maintainers who do not follow or enforce the Code of Conduct in good
+faith may face temporary or permanent repercussions as determined by other
+members of the project's leadership.
+
+## Attribution
+
+This Code of Conduct is adapted from the [Contributor Covenant][homepage], version 1.4,
+available at https://www.contributor-covenant.org/version/1/4/code-of-conduct.html

GOALS.md

+# The Syncthing Goals
+
+Syncthing is a **continuous file synchronization program**. It synchronizes
+files between two or more computers. We strive to fulfill the goals below.
+The goals are listed in order of importance, the most important one being
+the first.
+
+> "Syncing files" here is precise. It means we specifically exclude things
+> that are not files - calendar items, instant messages, and so on. If those
+> are in fact stored as files on disk, they can of course be synced as
+> files.
+
+Syncthing should be:
+
+### 1. Safe From Data Loss
+
+Protecting the user's data is paramount. We take every reasonable precaution
+to avoid corrupting the user's files.
+
+> This is the overriding goal, without which synchronizing files becomes
+> pointless. This means that we do not make unsafe trade offs for the sake
+> of performance or, in some cases, even usability.
+
+### 2. Secure Against Attackers
+
+Again, protecting the user's data is paramount. Regardless of our other
+goals, we must never allow the user's data to be susceptible to eavesdropping
+or modification by unauthorized parties.
+
+> This should be understood in context. It is not necessarily reasonable to
+> expect Syncthing to be resistant against well equipped state level
+> attackers. We will, however, do our best. Note also that this is different
+> from anonymity which is not, currently, a goal.
+
+### 3. Easy to Use
+
+Syncthing should be approachable, understandable, and inclusive.
+
+> Complex concepts and maths form the base of Syncthing's functionality.
+> This should nonetheless be abstracted or hidden to a degree where
+> Syncthing is usable by the general public.
+
+### 4. Automatic
+
+User interaction should be required only when absolutely necessary.
+
+> Specifically this means that changes to files are picked up without
+> prompting, conflicts are resolved without prompting and connections are
+> maintained without prompting. We only prompt the user when it is required
+> to fulfill one of the (overriding) Secure, Safe or Easy goals.
+
+### 5. Universally Available
+
+Syncthing should run on every common computer. We are mindful that the
+latest technology is not always available to every individual.
+
+> Computers include desktops, laptops, servers, virtual machines, small
+> general purpose computers such as Raspberry Pis and, *where possible*,
+> tablets and phones. NAS appliances, toasters, cars, firearms, thermostats,
+> and so on may include computing capabilities but it is not our goal for
+> Syncthing to run smoothly on these devices.
+
+### 6. For Individuals
+
+Syncthing is primarily about empowering the individual user with safe,
+secure, and easy to use file synchronization.
+
+> We acknowledge that it's also useful in an enterprise setting and include
+> functionality to support that. If this is in conflict with the
+> requirements of the individual, those will however take priority.
+
+### 7. Everything Else
+
+There are many things we care about that don't make it on to the list. It is
+fine to optimize for these values as well, as long as they are not in
+conflict with the stated goals above.
+
+> For example, performance is a thing we care about. We just don't care more
+> about it than safety, security, etc. Maintainability of the code base and
+> providing entertainment value for the maintainers are also things that
+> matter. It is understood that there are aspects of Syncthing that are
+> suboptimal or even in opposition with the goals above. However, we
+> continuously strive to align Syncthing more and more with these goals.

-Each encoded block begins with the varint-encoded length of the decoded data,
-followed by a sequence of chunks. Chunks begin and end on byte boundaries. The
-first byte of each chunk is broken into its 2 least and 6 most significant bits
-called l and m: l ranges in [0, 4) and m ranges in [0, 64). l is the chunk tag.
-Zero means a literal tag. All other values mean a copy tag.
-
-For literal tags:
-  - If m < 60, the next 1 + m bytes are literal bytes.
-  - Otherwise, let n be the little-endian unsigned integer denoted by the next
-    m - 59 bytes. The next 1 + n bytes after that are literal bytes.
-
-For copy tags, length bytes are copied from offset bytes ago, in the style of
-Lempel-Ziv compression algorithms. In particular:
-  - For l == 1, the offset ranges in [0, 1<<11) and the length in [4, 12).
-    The length is 4 + the low 3 bits of m. The high 3 bits of m form bits 8-10
-    of the offset. The next byte is bits 0-7 of the offset.
-  - For l == 2, the offset ranges in [0, 1<<16) and the length in [1, 65).
-    The length is 1 + m. The offset is the little-endian unsigned integer
-    denoted by the next 2 bytes.
-  - For l == 3, this tag is a legacy format that is no longer supported.

-                       Version 3, 29 June 2007
-
- Copyright (C) 2007 Free Software Foundation, Inc. <http://fsf.org/>
- Everyone is permitted to copy and distribute verbatim copies
- of this license document, but changing it is not allowed.
-
-
-  This version of the GNU Lesser General Public License incorporates
-the terms and conditions of version 3 of the GNU General Public
-License, supplemented by the additional permissions listed below.
-
-  0. Additional Definitions.
-
-  As used herein, "this License" refers to version 3 of the GNU Lesser
-General Public License, and the "GNU GPL" refers to version 3 of the GNU
-General Public License.
-
-  "The Library" refers to a covered work governed by this License,
-other than an Application or a Combined Work as defined below.
-
-  An "Application" is any work that makes use of an interface provided
-by the Library, but which is not otherwise based on the Library.
-Defining a subclass of a class defined by the Library is deemed a mode
-of using an interface provided by the Library.
-
-  A "Combined Work" is a work produced by combining or linking an
-Application with the Library.  The particular version of the Library
-with which the Combined Work was made is also called the "Linked
-Version".
-
-  The "Minimal Corresponding Source" for a Combined Work means the
-Corresponding Source for the Combined Work, excluding any source code
-for portions of the Combined Work that, considered in isolation, are
-based on the Application, and not on the Linked Version.
-
-  The "Corresponding Application Code" for a Combined Work means the
-object code and/or source code for the Application, including any data
-and utility programs needed for reproducing the Combined Work from the
-Application, but excluding the System Libraries of the Combined Work.
-
-  1. Exception to Section 3 of the GNU GPL.
-
-  You may convey a covered work under sections 3 and 4 of this License
-without being bound by section 3 of the GNU GPL.
-
-  2. Conveying Modified Versions.
-
-  If you modify a copy of the Library, and, in your modifications, a
-facility refers to a function or data to be supplied by an Application
-that uses the facility (other than as an argument passed when the
-facility is invoked), then you may convey a copy of the modified
-version:
-
-   a) under this License, provided that you make a good faith effort to
-   ensure that, in the event an Application does not supply the
-   function or data, the facility still operates, and performs
-   whatever part of its purpose remains meaningful, or
-
-   b) under the GNU GPL, with none of the additional permissions of
-   this License applicable to that copy.
-
-  3. Object Code Incorporating Material from Library Header Files.
-
-  The object code form of an Application may incorporate material from
-a header file that is part of the Library.  You may convey such object
-code under terms of your choice, provided that, if the incorporated
-material is not limited to numerical parameters, data structure
-layouts and accessors, or small macros, inline functions and templates
-(ten or fewer lines in length), you do both of the following:
-
-   a) Give prominent notice with each copy of the object code that the
-   Library is used in it and that the Library and its use are
-   covered by this License.
-
-   b) Accompany the object code with a copy of the GNU GPL and this license
-   document.
-
-  4. Combined Works.
-
-  You may convey a Combined Work under terms of your choice that,
-taken together, effectively do not restrict modification of the
-portions of the Library contained in the Combined Work and reverse
-engineering for debugging such modifications, if you also do each of
-the following:
-
-   a) Give prominent notice with each copy of the Combined Work that
-   the Library is used in it and that the Library and its use are
-   covered by this License.
-
-   b) Accompany the Combined Work with a copy of the GNU GPL and this license
-   document.
-
-   c) For a Combined Work that displays copyright notices during
-   execution, include the copyright notice for the Library among
-   these notices, as well as a reference directing the user to the
-   copies of the GNU GPL and this license document.
-
-   d) Do one of the following:
-
-       0) Convey the Minimal Corresponding Source under the terms of this
-       License, and the Corresponding Application Code in a form
-       suitable for, and under terms that permit, the user to
-       recombine or relink the Application with a modified version of
-       the Linked Version to produce a modified Combined Work, in the
-       manner specified by section 6 of the GNU GPL for conveying
-       Corresponding Source.
-
-       1) Use a suitable shared library mechanism for linking with the
-       Library.  A suitable mechanism is one that (a) uses at run time
-       a copy of the Library already present on the user's computer
-       system, and (b) will operate properly with a modified version
-       of the Library that is interface-compatible with the Linked
-       Version.
-
-   e) Provide Installation Information, but only if you would otherwise
-   be required to provide such information under section 6 of the
-   GNU GPL, and only to the extent that such information is
-   necessary to install and execute a modified version of the
-   Combined Work produced by recombining or relinking the
-   Application with a modified version of the Linked Version. (If
-   you use option 4d0, the Installation Information must accompany
-   the Minimal Corresponding Source and Corresponding Application
-   Code. If you use option 4d1, you must provide the Installation
-   Information in the manner specified by section 6 of the GNU GPL
-   for conveying Corresponding Source.)
-
-  5. Combined Libraries.
-
-  You may place library facilities that are a work based on the
-Library side by side in a single library together with other library
-facilities that are not Applications and are not covered by this
-License, and convey such a combined library under terms of your
-choice, if you do both of the following:
-
-   a) Accompany the combined library with a copy of the same work based
-   on the Library, uncombined with any other library facilities,
-   conveyed under the terms of this License.
-
-   b) Give prominent notice with the combined library that part of it
-   is a work based on the Library, and explaining where to find the
-   accompanying uncombined form of the same work.
-
-  6. Revised Versions of the GNU Lesser General Public License.
-
-  The Free Software Foundation may publish revised and/or new versions
-of the GNU Lesser General Public License from time to time. Such new
-versions will be similar in spirit to the present version, but may
-differ in detail to address new problems or concerns.
-
-  Each version is given a distinguishing version number. If the
-Library as you received it specifies that a certain numbered version
-of the GNU Lesser General Public License "or any later version"
-applies to it, you have the option of following the terms and
-conditions either of that published version or of any later version
-published by the Free Software Foundation. If the Library as you
-received it does not specify a version number of the GNU Lesser
-General Public License, you may choose any version of the GNU Lesser
-General Public License ever published by the Free Software Foundation.
-
-  If the Library as you received it specifies that a proxy can decide
-whether future versions of the GNU Lesser General Public License shall
-apply, that proxy's public statement of acceptance of any version is
-permanent authorization for you to choose that version for the
-Library.

-    import "github.com/juju/ratelimit"
-
-The ratelimit package provides an efficient token bucket implementation. See
-http://en.wikipedia.org/wiki/Token_bucket.
-
-## Usage
-
-#### func  Reader
-
-```go
-func Reader(r io.Reader, bucket *Bucket) io.Reader
-```
-Reader returns a reader that is rate limited by the given token bucket. Each
-token in the bucket represents one byte.
-
-#### func  Writer
-
-```go
-func Writer(w io.Writer, bucket *Bucket) io.Writer
-```
-Writer returns a reader that is rate limited by the given token bucket. Each
-token in the bucket represents one byte.
-
-#### type Bucket
-
-```go
-type Bucket struct {
-}
-```
-
-Bucket represents a token bucket that fills at a predetermined rate. Methods on
-Bucket may be called concurrently.
-
-#### func  NewBucket
-
-```go
-func NewBucket(fillInterval time.Duration, capacity int64) *Bucket
-```
-NewBucket returns a new token bucket that fills at the rate of one token every
-fillInterval, up to the given maximum capacity. Both arguments must be positive.
-The bucket is initially full.
-
-#### func  NewBucketWithQuantum
-
-```go
-func NewBucketWithQuantum(fillInterval time.Duration, capacity, quantum int64) *Bucket
-```
-NewBucketWithQuantum is similar to NewBucket, but allows the specification of
-the quantum size - quantum tokens are added every fillInterval.
-
-#### func  NewBucketWithRate
-
-```go
-func NewBucketWithRate(rate float64, capacity int64) *Bucket
-```
-NewBucketWithRate returns a token bucket that fills the bucket at the rate of
-rate tokens per second up to the given maximum capacity. Because of limited
-clock resolution, at high rates, the actual rate may be up to 1% different from
-the specified rate.
-
-#### func (*Bucket) Rate
-
-```go
-func (tb *Bucket) Rate() float64
-```
-Rate returns the fill rate of the bucket, in tokens per second.
-
-#### func (*Bucket) Take
-
-```go
-func (tb *Bucket) Take(count int64) time.Duration
-```
-Take takes count tokens from the bucket without blocking. It returns the time
-that the caller should wait until the tokens are actually available.
-
-Note that if the request is irrevocable - there is no way to return tokens to
-the bucket once this method commits us to taking them.
-
-#### func (*Bucket) TakeAvailable
-
-```go
-func (tb *Bucket) TakeAvailable(count int64) int64
-```
-TakeAvailable takes up to count immediately available tokens from the bucket. It
-returns the number of tokens removed, or zero if there are no available tokens.
-It does not block.
-
-#### func (*Bucket) TakeMaxDuration
-
-```go
-func (tb *Bucket) TakeMaxDuration(count int64, maxWait time.Duration) (time.Duration, bool)
-```
-TakeMaxDuration is like Take, except that it will only take tokens from the
-bucket if the wait time for the tokens is no greater than maxWait.
-
-If it would take longer than maxWait for the tokens to become available, it does
-nothing and reports false, otherwise it returns the time that the caller should
-wait until the tokens are actually available, and reports true.
-
-#### func (*Bucket) Wait
-
-```go
-func (tb *Bucket) Wait(count int64)
-```
-Wait takes count tokens from the bucket, waiting until they are available.
-
-#### func (*Bucket) WaitMaxDuration
-
-```go
-func (tb *Bucket) WaitMaxDuration(count int64, maxWait time.Duration) bool
-```
-WaitMaxDuration is like Wait except that it will only take tokens from the
-bucket if it needs to wait for no greater than maxWait. It reports whether any
-tokens have been removed from the bucket If no tokens have been removed, it
-returns immediately.
