Diff is large due to comment reformatting and indentation but all it
does is wrap the file mtime/size/permissions check in an "if
stat.IsRegular()".

This removes a significant, complex chunk of database code. The
"replace" operation walked both the old and new in lockstep and made the
relevant changes to make the new situation correct. But since delta
indexes we pretty much never need this - we just used replace to drop
the existing data and start over.
This makes that explicit and removes the complexity.
(This is one of those things that would be annoying to make case
insensitive, while the actual "drop and then insert" that we do is
easier.)
This is fairly well unit tested...
The one change to the tests is to cover the fact that previously replace
with something identical didn't bump the sequence number, while
obviously removing everything and re-inserting does. This is not
behavior we depend on anywhere.

With VPNs and stuff we can get a single failure on an interface that
supposedly supports broadcasts without it being fatal.

The folder marker conversion forgot to hide the .stfolder. This adds
that, for those who have not yet been converted.
Also adds Hide() calls to the folder start, to mend historical
unhidedness. (I'm sure this will upset someone who is manually managing
their .stignores in the other direction...)

When STHASHING is set, don't benchmark as it's already decided. If weak
hashing isn't set to "auto", don't benchmark that either.

These functions were very naive and slow. We haven't done much about
them because they pretty much don't matter at all for Syncthing
performance. They are however called very often in the discovery server
and these optimizations have a huge effect on the CPU load on the
public discovery servers.
The code isn't exactly obvious, but we have good test coverage on all
these functions.

Currently all errors during pulling and the first of these errors again on
finishing are logged to info. Besides that the errors logged when finishing
are stored in f.errors. This PR moves all logging during pulling to the debug
channel (they might still be relevant in some obscure debugging case) and
uses the stored errors to log the main error per fail when all pulling
iterations are done and failed.
Additional instead of trying 11 times it now only tries 3 times.
This is the first part of what is discussed here:

This updates kcp and uses our own fork which:
1. Keys sessions not just by remote address, but by remote address +
conversation id 2. Allows not to close connections that were passed directly
to the library. 3. Resets cache key if the session gets terminated.
