* 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.
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 makes version vector values clock based instead of just incremented
from zero. The effect is that a vector that is created from scratch
(after database reset) will have a higher value for the local device
than what it could have been previously, causing a conflict. That is, if
we are A and we had
{A: 42, B: 12}
in the old scheme, a reset and rescan would give us
{A: 1}
which is a strict ancestor of the older file (this might be wrong). With
the new scheme we would instead have
{A: someClockTime, b: otherClockTime}
and the new version after reset would become
{A: someClockTime+delta}
which is in conflict with the previous entry (better).
In case the clocks are wrong (current time is less than the value in the
vector) we fall back to just simple increment like today.
This scheme is ineffective if we suffer a database reset while at the
same time setting the clock back far into the past. It's however no
worse than what we already do.
This loses the ability to emit the "added" event, as we can't look for
the magic 1 entry any more. That event was however already broken
(#5541).
Another place where we infer meaning from the vector itself is in
receive only folders, but there the only criteria is that the vector is
one item long and includes just ourselves, which remains the case with
this change.
