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.
In principle a connection can close while it's in progress with
starting, and then it's undefined if we wait for goroutines to exit etc.
With this change, we will wait for start to complete before starting to
stop everything.
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...

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.
Summarize platforms that fail to build, without overloading the build
log with errors that we anyway ignore. (Currently freebsd/riscv64 fails
to build.)
By creating the http.Transport and tls.Configuration ourselves we
override some default behavior and end up with a client that speaks only
HTTP/1.1.
This adds a call to http.ConfigureTransport to do the relevant magic to
enable HTTP/2.
Also tweaks the keepalive settings to be a little kinder to the
server(s).
Currently, historically, we look for the `X-API-Key` header to
authenticate with an API key. There's nothing wrong with this, but in
some scenarios it's easier to produce an `Authorization` header with a
`Bearer $token` content, which is nowadays more common. This change adds
support for both, so that we will accept an API key either in our custom
header or as a bearer token.
This adds an environment variable STVERSIONEXTRA that, when set, gets
added to the version information in the API and GUI.
The purpose of all this is to be able to communicate something about the
bundling or packaging, through the log & GUI and the end user, to the
potential person supporting it -- i.e., us. :) A wrapper can set this
variable to indicate that Syncthing is being run via `SyncTrayzor`,
`Syncthing-macOS`, etc., and thus indicate to the end user that the GUI
they are looking at is perhaps not the only source of truth and
management for this instance.
With this change, error messages include the offending characters or
name parts. Examples:
nul.txt: name is invalid, contains Windows reserved name: "nul"
foo>bar.txt: name is invalid, contains Windows reserved character: ">"
foo \bar.txt: name is invalid, must not end in space or period on Windows
This adds builds for the discovery and relay servers in the same manner
as Syncthing, so that Docker images are kept up to date with releases.
Inspired by and closes#8834.

This removes the tilde expansion we had in the GUI. I'm not sure why we
had it, but there are valid reasons to have a folder path with tilde in
it in the config, and it was previously impossible to enter one of
those.
This allows environment overrides for our directories. This is
advantageous because, apart from the obvious, it means we can set it in
the Docker file and not add command line options there. Having the
command line option as we did meant that it was impossible to use the
Docker image for other commands than `serve` (because that is implied
when we see other options on the command line).
This prevents combining untrusted with introducer and auto-accept, and
also verifies that folders shared with untrusted devices have passwords
at config loading time.

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 makes the various protocol priorities configurable among the other
options. With this, it's possible to prefer QUIC over TCP for WAN
connections, for example. Both sides need to be similarly configured for
this to work properly.
The default priority order remains the same as previously (TCP, QUIC,
Relay, with LAN better than WAN).
To make this happen I made each dialer & listener more priority aware,
and moved the check for whether a connection is LAN or not into the
dialer / listener -- this is the new "lanChecker" type that's passed
around.
