lib/events: Become a service (fixes #5372) (#5373)
Here the event Logger is rewritten as a service with a main loop instead
of mutexes. This loop has a select with essentially two legs: incoming
events, and subscription changes. When both are possible select will
chose one randomly, thus ensuring that in practice unsubscribes will
happen timely and not block the system.

d48e46a29c cmd/syncthing: Allow custom event subscriptions (fixes #1879)
This adds a parameter "events" to the /rest/events endpoint. It should
be a comma separated list of the events the consumer is interested in.
When not given it defaults to the current set of events, so it's
backwards compatible.

The API service then manages subscriptions, creating them as required
for each requested event mask. Old subscriptions are not "garbage
collected" - it's assumed that in normal usage the set of event
subscriptions will be small enough. Possibly lower than before, as we
will not set up the disk event subscription unless it's actually used.

fdcbd54cd7 lib/events: Be more resilient against dropping events (fixes #3952)
Instead of just immediately dropping the event if the subscription isn't
ready to receive it, give it 15 ms to catch up. The value 15 ms is
grabbed out of thin air - it just seems reasonable to me.

The timer juggling makes the event send pretty much exactly twice as
slow as it was before, but we're still under a microsecond. I think it's
negligible compared to whatever event that just happened that we're
interested in logging (usually a file operation of some kind).

7ef2743964 lib/events: Introduce per-subscription event IDs (fixes #3335)
Events API consumers rely on being able to detect that events were skipped
by the fact that the event ID has increased by more than 1. This is
documented, and is absolutely necessary when trying to maintain a local
model of Syncthing's state.

With the introduction of LocalChangeDetected, which is not exposed to the
Events API, this contract was broken.

This commit introduces separate concepts of a "Global ID" and a
"Subscription ID". The Global ID of an event is unique across all
subscriptions. The Subscription ID is local to a particular subscription,
and always increments by 1. They are both exposed over the Events API, but
the Subscription ID uses the key "id" for backwards compatibility, and
the "?since=xx" parameter refers to the Subscription ID (making the Global
ID for information only).

a0ec4467fd cmd/syncthing: Emit new RemoteDownloadProgress event to track remote download progress
Without this the summary service doesn't know to recalculate completion
percentage for remote devices when DownloadProgress messages come in.
That means that completion percentage isn't updated in the GUI while
transfers of large files are ongoing. With this change, it updates
correctly.

1dbc310c9b cmd/syncthing: Rename event LocalDiskUpdated -> LocalChangeDetected
I think this better reflects what it means. Also tweaks the verbose
format to be more like our other things and lightly refactors the code
to not have the boolean and include the folder in the event.

674fc566bb lib/connections: Refactor
1. Removes separate relay lists and relay clients/services, just makes it a listen address
2. Easier plugging-in of other transports
3. Allows "hot" disabling and enabling NAT services
4. Allows "hot" listen address changes
5. Changes listen address list with a preferable "default" value just like for discovery
6. Debounces global discovery announcements as external addresses change (which it might alot upon starting)
7. Stops this whole "pick other peers relay by latency". This information is no longer available,
   but I don't think it matters as most of the time other peer only has one relay.
8. Rename ListenAddress to ListenAddresses, as well as in javascript land.
9. Stop serializing deprecated values to JSON

76af9ba53d Implement facility based logger, debugging via REST API
This implements a new debug/trace infrastructure based on a slightly
hacked up logger. Instead of the traditional "if debug { ... }" I've
rewritten the logger to have no-op Debugln and Debugf, unless debugging
has been enabled for a given "facility". The "facility" is just a
string, typically a package name.

This will be slightly slower than before; but not that much as it's
mostly a function call that returns immediately. For the cases where it
matters (the Debugln takes a hex.Dump() of something for example, and
it's not in a very occasional "if err != nil" branch) there is an
l.ShouldDebug(facility) that is fast enough to be used like the old "if
debug".

The point of all this is that we can now toggle debugging for the
various packages on and off at runtime. There's a new method
/rest/system/debug that can be POSTed a set of facilities to enable and
disable debug for, or GET from to get a list of facilities with
descriptions and their current debug status.

Similarly a /rest/system/log?since=... can grab the latest log entries,
up to 250 of them (hardcoded constant in main.go) plus the initial few.

Not implemented in this commit (but planned) is a simple debug GUI
available on /debug that shows the current log in an easily pasteable
format and has checkboxes to enable the various debug facilities.

The debug instructions to a user then becomes "visit this URL, check
these boxes, reproduce your problem, copy and paste the log". The actual
log viewer on the hypothetical /debug URL can poll regularly for new log
entries and this bypass the 250 line limit.

The existing STTRACE=foo variable is still obeyed and just sets the
start state of the system.

d6e34761dc Fix events timeout errors
Resetting the timeout doesn't fully cut it, as it may timeout after we
