73e492c9db refactor: move from io/ioutil to io and os package (#1360)
* refactor: move from io/ioutil to io and os package

The io/ioutil package has been deprecated as of Go 1.16, see
https://golang.org/doc/go1.16#ioutil. This commit replaces the existing
io/ioutil functions with their new definitions in io and os packages.

* chore: remove //nolint:gosec for os.ReadFile

At the time of this commit, the G304 rule of gosec does not include the
`os.ReadFile` function. We remove `//nolint:gosec` temporarily until
https://github.com/securego/gosec/pull/706 is merged.

35d0f31c0d huge: replaced the use of allocated byte slices with populating gather.WriteBuffer in the repository (#1244)
This helps recycle buffers more efficiently during snapshots.
Also, improved memory tracking, enabled profiling flags and added pprof
by default.

e03971fc59 Upgraded linter to v1.33.0 (#734)
* linter: upgraded to 1.33, disabled some linters

* lint: fixed 'errorlint' errors

This ensures that all error comparisons use errors.Is() or errors.As().
We will be wrapping more errors going forward so it's important that
error checks are not strict everywhere.

Verified that there are no exceptions for errorlint linter which
guarantees that.

* lint: fixed or suppressed wrapcheck errors

* lint: nolintlint and misc cleanups

6a93e4d5b9 Added support for scanning only one filesystem via files policy (#676)
The new files policy oneFileSystem ignores files that are mounted to
other filesystems similarly to tar's --one-file-system switch. For
example, if this is enabled, backing up / should now automatically
ignore /dev, /proc, etc, so the directory entries themselves don't
appear in the backup. The value of the policy is 'false' by default.

This is implemented by adding a non-windows-field Device (of type
DeviceInfo, reflecting the implementation of Owner) to the Entry
interface. DeviceInfo holds the dev and rdev acquired with stat (same
way as with Owner), but in addition to that it also holds the same
values for the parent directory. It would seem that doing this in some
other way, ie. in ReadDir, would require modifying the ReadDir
interface which seems a too large modification for a feature this
small.

This change introduces a duplication of 'stat' call to the files, as
the Owner feature already does a separate call. I doubt the
performance implications are noticeable, though with some refactoring
both Owner and Device fields could be filled in in one go.

Filling in the field has been placed in fs/localfs/localfs.go where
entryFromChildFileInfo has acquired a third parameter giving the the
parent entry. From that information the Device of the parent is
retrieved, to be passed off to platformSpecificDeviceInfo which does
the rest of the paperwork. Other fs implementations just put in the
default values.

The Dev and Rdev fields returned by the 'stat' call have different
sizes on different platforms, but for convenience they are internally
handled the same. The conversion is done with local_fs_32bit.go and
local_fs_64bit.go which are conditionally compiled on different
platforms.

Finally the actual check of the condition is in ignorefs.go function
shouldIncludeByDevice which is analoguous to the other similarly named
functions.

514df69afa performance: added wrapper around io.Copy()

after each io.Copy()

c8fcae93aa logging: refactored logging
This is mostly mechanical and changes how loggers are instantiated.

Logger is now associated with a context, passed around all methods,
(most methods had ctx, but had to add it in a few missing places).

By default Kopia does not produce any logs, but it can be overridden,
either locally for a nested context, by calling

ctx = logging.WithLogger(ctx, newLoggerFunc)

To override logs globally, call logging.SetDefaultLogger(newLoggerFunc)

This refactoring allowed removing dependency from Kopia repo
and go-logging library (the CLI still uses it, though).

It is now also possible to have all test methods emit logs using
t.Logf() so that they show up in failure reports, which should make
debugging of test failures suck less.

d3f324f59b Add diff.compareEntry helper to compare attribute entries
- Use it to compare the entry attributes for all entry types.
  Allows comparing differences in file attributes among the
  contents of two directories. This is useful for verifying
  restored contents in end-to-end tests.

- Print message about modified entries only when both entries
  are files and they are being compared.
