lib/fs, lib/model: Be careful about potentially negative durations (fixes #9112) (#9113)
I don't really understand under what circumstances, but sometimes these
calls panic with a "panic: counter cannot decrease in value" because the
value passed to Add() was negative.

all: Support multiple device connections (fixes #141) (#8918)
This adds the ability to have multiple concurrent connections to a single device. This is primarily useful when the network has multiple physical links for aggregated bandwidth. A single connection will never see a higher rate than a single link can give, but multiple connections are load-balanced over multiple links.

It is also incidentally useful for older multi-core CPUs, where bandwidth could be limited by the TLS performance of a single CPU core -- using multiple connections achieves concurrency in the required crypto calculations...

lib/model: Refactor folderRunners to use a serviceMap (#9071)
Instead of separately tracking the token.

Also changes serviceMap to have a channel version of RemoveAndWait, so
that it's possible to do the removal under a lock but wait outside of
the lock. And changed where we do that in connection close, reversing
the change that happened when I added the serviceMap in 40b3b9ad1.

all: Remove lib/util package (#9049)
Grab-bag packages are nasty, this cleans it up a little by splitting it
into topical packages sempahore, netutil, stringutil, structutil.

lib/versioner: Minor fixes in comments and error message (#9031)
* lib/versioner: Factor out DefaultPath constant.

Replace several instances where .stversions is named literally to all
use the same definition in the versioner package.  Exceptions are the
packages where a cyclic dependency on versioner is impossible, or some
tests which combine the versions base path with other components.

* lib/versioner: Fix comment about trash can in simple versioner.

* lib/versioner: Fix wrong versioning type string in error message.

The error message shows the folder type instead of the versioning
type, although the correct field is used in the comparison.

all: replace empty slice literal with var (#8990)
refactor: replace empty slice literal with `var`

An empty slice can be represented by `nil` or an empty slice literal. They are
functionally equivalent — their `len` and `cap` are both zero — but the `nil`
slice is the preferred style. For more information about empty slices,
see [Declaring Empty Slices](https://github.com/golang/go/wiki/CodeReviewComments#declaring-empty-slices).

refactor: fix unused method receiver

Methods with unused receivers can be a symptom of unfinished refactoring or a bug. To keep 
the same method signature, omit the receiver name or '_' as it is unused.

1103a27337 all: Grand test refactor (fixes #8779, fixes #8799)
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

lib/model: Set enc. trailer size on pull (ref #8563, #8556) (#8839)
In the original fix in #8563 I simply forgot this. Which meant #8556
wasn't actually fixed, as the trialer size would have been 0 (default),
and thus we would have still sent the inflated size to encrypted peers.

lib/model: Fix file size inconsistency due to enc. trailer (#8840)
lib/model: Fix file size inconsisency due to enc. trailer

Fixes a regression due to PR #8563, while arguable the bug was actually
introduced in a much older PR #7155, but didn't have any bad effects so
far:
We account for the encryption trailer in the db updater routine,
calculating the file-info size there. However there's no guarantee that
the file-info at this point is still the exact same as when it was
written. It was before, but isn't anymore since introducing the new
EncryptedTrailerSize field.
Fix: Adjust the size in the info at the same place where the trailer is
written, i.e. we definitely have the actual size on disk.

gui, lib/connections: Let the backend decide whether connection is local (fixes #8686) (#8694)
* lib/connections: Cache isLAN decision for later external access.

The check whether a remote device's address is on a local network
currently happens when handling the Hello message, to configure the
limiters.  Save the result to the ConnectionInfo and pass it out as
part of the model's ConnectionInfo struct in ConnectionStats().

* gui: Use provided connection attribute to distinguish LAN / WAN.

Replace the dumb IP address check which didn't catch common cases and
actually could contradict what the backend decided.  That could have
been confusing if the GUI says WAN, but the limiter is not actually
applied because the backend thinks it's a LAN.

Add strings for QUIC and relay connections to also differentiate
between LAN and WAN.

* gui: Redefine reception level icons for all connection types.

Move the mapping to the JS code, as it is much easier to handle
multiple switch cases by fall-through there.

QUIC is regarded no less than TCP anymore.  LAN and WAN make the
difference between levels 4 / 3 and 2 / 1:

{TCP,QUIC} LAN --> {TCP,QUIC} WAN --> Relay LAN --> Relay WAN -->
Disconnected.

all: Support syncing extended attributes (fixes #2698) (#8513)
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).

all: Modernize error wrapping (#8491)
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.

build: Update quic-go for Go 1.19 (#8483)
Also adds idle time and keepalive parameters because how this is
configured has changed in the new package version. The values are those
that seems like might already be default, if keep-alives were enabled,
which is not obvious from the doc comments.

Also, Go 1.19 gofmt reformatting of comments.

all: Add package runtimeos for runtime.GOOS comparisons

I grew tired of hand written string comparisons. This adds generated
constants for the GOOS values, and predefined Is$OS constants that can
be iffed on. In a couple of places I rewrote trivial switch:es to if:s,
and added Illumos where we checked for Solaris (because they are
effectively the same, and if we're going to target one of them that
would be Illumos...).
