This fixes the change in #6674 where the weak hash became a deciding
factor. Now we again just use it to accept a block, but don't take a
negative as meaning the block is bad.
This extracts the extra tags from any `[foo]` stuff at the end of the
version and sends them to Sentry for indexing.
If I need to modify that regexp again I'll probably write a from scratch
tokenizer and parser for our version string instead...
This adds some env vars to the long version string as if they were build
tags. The purpose is to better understand what code was running or not
in the version output, usage reporting and crash reports. In order to
prevent possible privacy issues the actual value of the variable is not
reported, just the fact that it was set to something non-empty.
Example:
% ./bin/syncthing --version
syncthing v1.6.1+47-g1eb104f3-buildtags "Fermium Flea" (go1.14.3 darwin-amd64) jb@kvin.kastelo.net 2020-06-03 07:25:46 UTC [stnoupgrade, use_badger]
Group the global list of files by version, instead of having one flat list for all devices. This removes lots of duplicate protocol.Vectors.

This reduces the size of our write batches before we flush them. This
has two effects: reducing the amount of data lost if we crash when
updating the database, and reducing the amount of memory used when we do
large updates without checkpoint (e.g., deleting a folder).
I ran our SyncManyFiles benchmark as it is the one doing most
transactions, however there was no relevant change in any metric (it's
limited by our fsync I expect). This is good as any visible change would
just be a decrease in performance.
I don't have a benchmark on deleting a large folder, taking that part on
trust for now...
* cmd/stindex: Unify access to key from cached variable.
Avoid calling the Key() method from the iterator each time the value
is needed. Just reuse the cache variable already assigned before the
switch block.
* cmd/stindex: Display the prefix byte value for unknown key types.
Make it easier to diagnose corrupt / unknown key type entries by
showing their decimal value, correlating with the definitions in
keyer.go.
* cmd/stindex: Add missing KeyType values in stindex dump code.
Recently added DB key prefixes KeyTypeBlockListMap and KeyTypeVersion
were unknown to the stindex dumping tool. Add basic parsing to dump
their key structure.
If we fail to take the rename shortcut we may crash on a later loop,
because we do trickiness with the indexes but the original buckets[key]
in "range buckets[key]" isn't re-evaluated so i exceeds the max index.
