On kqueue-systems, folders listen for folder summaries to (be able to)
warn for potential high resource usage. However, it listened for any
folder summary and not for the summary which matches the folder it's
about. This could cause that an unwatched folder causes a folder summary
containing more files than the threshold (10k), and the listening folder
(with the watcher enabled) triggers the warning.
This makes sure that only the folder summaries which are relevant to the
specific folder are being handled.
### Testing
- Fire up some kqueue-system (freebsd, I used).
- add folder A, disable the watcher, add 10001 files
- add folder B with the watcher enabled, no files are needed here
Before the change:
- add an item to folder A, trigger a rescan to speed up the process
- wait some seconds...warning triggered by folder B's
summarySubscription
After the change:
- Only a warning is triggered if the received folder summary matches the
folder which listens for the summaries
This fixes various test issues with Go 1.20.
- Most tests rewritten to use fakefs where possible
- Some tests that were already skipped, or dubious (invasive,
unmaintainable, unclear what they even tested) have been removed
- Some actual code rewritten to better support testing in fakefs

This adds support for syncing extended attributes on supported
filesystem on Linux, macOS, FreeBSD and NetBSD. Windows is currently
excluded because the APIs seem onerous and annoying and frankly the uses
cases seem few and far between. On Unixes this also covers ACLs as those
are stored as extended attributes.
Similar to ownership syncing this will optional & opt-in, which two
settings controlling the main behavior: one to "sync" xattrs (read &
write) and another one to "scan" xattrs (only read them so other devices
can "sync" them, but not apply any locally).

This replaces old style errors.Wrap with modern fmt.Errorf and removes
the (direct) dependency on github.com/pkg/errors. A couple of cases are
adjusted by hand as previously errors.Wrap(nil, ...) would return nil,
which is not what fmt.Errorf does.
This adds support for syncing ownership on Unixes and on Windows. The
scanner always picks up ownership information, but it is not applied
unless the new folder option "Sync Ownership" is set.
Ownership data is stored in a new FileInfo field called "platform data". This
is intended to hold further platform-specific data in the future
(specifically, extended attributes), which is why the whole design is a
bit overkill for just ownership.
* lib/api: Note ItemStarted and ItemFinished for default filtering.
The reasoning why LocalChangeDetected and RemoteChangeDetected events
are not included in the event stream by default (without explicit
filter mask requested) also holds for the ItemStarted and ItemFinished
events. They should be excluded as well when we start to break the
API compatibility for some reason.
* gui: Enumerate unused event types in the eventService.
Define constants for the unused event types as well, for completeness'
sake. They are intentionally not handled in the GUI currently.
* cmd/syncthing: Harmonize uppercase CLI argument placeholders.
Use ALL-UPPERCASE and connecting dashes to distinguish argument
placeholders from literal argument options (e.g. "cpu" or "heap" for
profiling). The dash makes it clear which words form a single
argument and where a new argument starts.
This style is already used for the "syncthing cli debug file" command.
* lib/model: Simplify event data structure.
Using map[string]interface{} is not necessary when all values are
known to be strings.
