Basically, if we don't care about the sync status of the file we should
not tag someone else out of sync because they don't have the latest
version. This solves *my* "Syncing - 100%" scenario at least.
The reason this happens seems to be like this, in my situation. I have
three devices, connected in a "line": A-B-C. A is a Mac and litters
.DS_Store files everywhere. I've ignored these, but some escaped into
the folders before I did so. I've also ignored them on B and C but at
different stages. B was flagging C as out of sync, because at the point
the ignores were introduced C had a lower version of .DS_Store than A.
Now none of them are sending updates about it any more since it's
ignored...

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.

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.

Can't do what I did, as the rolling function is not the same as the
non-rolling one. Instead this uses an improved version of the rolling
adler32 to accomplish the same thing. (PR filed on upstream, so should
be able to use that directly in the future.)
The rolling version of adler32 is just a wrapper around the standard
hash/adler32 when used in a non-rolling fashion, but it's inefficient as
it allocates a new hash instance for every Write(). This uses the
default version instead in the block hasher, and adds a test to verify
the result is the same as they were before. It reduces allocations by
88% and increases speed about 5%.

On Windows we would descend into SYMLINKD type links when we scanned
them successfully, as we would return nil from the walk function and the
filepath.Walk iterator apparently thought it OK to descend into the
symlinked directory.
With this change we always return filepath.SkipDir no matter what.
Tested on Windows 10 as admin, does what it should.

Also tweaks the proto definitions:
- [packed=false] on the block_indexes field to retain compat with
v0.14.16 and earlier.
- Uses the vendored protobuf package in include paths.
And, "build.go setup" will install the vendored protoc-gen-gogofast.
This should ensure that a proto rebuild isn't so dependent on whatever
version of the compiler and package the developer has installed...

The protobuf encoder now produces packed arrays for things like []int32,
which is actually correct according to the proto3 spec. However
Syncthing v0.14.16 and earlier doesn't support this. This reverts the
encoding change, but keeps the updated decoder so that we are both more
compatible with other proto3 implementations and can move to the updated
encoder in the future.

Since we anyway need the folderConfig for this I'm skipping the copying
of all it's attributes that rwfolder did and just keeping the original
around instead.

This adds support for AES_256_GCM_SHA384 (in there since Go 1.5, a bit
of a shame we missed it) and ChaCha20-Poly1305 (if built with Go 1.8;
ignored on older Gos).
