After this change,
- Symlinks on Windows are always unsupported. Sorry.
- Symlinks are always enabled on other platforms. They are just a small
file like anything else. There is no need to special case them. If you
don't want to sync some symlinks, ignore them.
- The protocol doesn't differentiate between different "types" of
symlinks. If that distinction ever does become relevant the individual
devices can figure it out by looking at the destination when they
create the link.
It's backwards compatible in that all the old symlink types are still
understood to be symlinks, and the new SYMLINK type is equivalent to the
old SYMLINK_UNKNOWN which was always a valid way to do it.

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).

The monitor process should not set STNORESTART as this indicates the
intention from the user. Setting STMONITORED is enough, as this tells
the next Syncthing instance that it is running under the monitor
process.

The Ping event is important, as it means that requests complete within
a sensible time. The disk events API didn't have the Ping event, so
if there were no disk events, the request would keep taking forever.
Unless, of course, there's a reverse proxy which times the request out
after a suitably large interval (or something else aborts it), in which
case Syncthing isn't very happy.

Instead of
[I6KAH] 19:05:56 INFO: Single thread hash performance is 359 MB/s using minio/sha256-simd (354 MB/s using crypto/sha256).
it now says
[I6KAH] 19:06:16 INFO: Single thread SHA256 performance is 359 MB/s using minio/sha256-simd (354 MB/s using crypto/sha256).
[I6KAH] 19:06:17 INFO: Actual hashing performance is 299.01 MB/s
which is more informative. This is also the number it reports in usage
reporting.
