This adds a thin type that holds the state associated with the
leveldb.DB, leaving the huge Instance type more or less stateless. Also
moves some keying stuff into the DB package so that other packages need
not know the keying specifics.
(This does not, yet, fix the cmd/stindex program, in order to keep the
diff size down. Hence the keying constants are still exported.)
* lib/model, cmd/syncthing: Wait for folder restarts to complete (fixes#5233)
This is the somewhat ugly - but on the other hand clear - fix for what
is really a somewhat thorny issue. To avoid zombie folder runners a new
mutex is introduced that protects the RestartFolder operation. I hate
adding more mutexes but the alternatives I can think of are worse.
The other part of it is that the POST /rest/system/config operation now
waits for the config commit to complete. The point of this is that until
the commit has completed we should not accept another config commit. If
we did, we could end up with two separate RestartFolders queued in the
background. While they are both correct, and will run without
interfering with each other, we can't guarantee the order in which they
will run. Thus it could happen that the newer config got committed
first, and the older config commited after that, leaving us with the
wrong config running.

* lib/fs: Add fakefs
This adds a new fake filesystem type. It's described rather extensively
in fakefs.go, but the main point is that it's for testing: when you want
to spin up a Syncthing and have a terabyte or two of random files that
can be synced somewhere, or an inifitely large filesystem to sync files
into.
It has pseudorandom properties such that data read from one fakefs can
be written into another fakefs and read back and it will look
consistent, without any of the data actually being stored.
To use:
<folder id="default" path="whatever" ...>
<filesystemType>fake</filesystemType>
This will create an empty fake filesystem. You can also specify that it
should be prefilled with files:
<folder id="default" path="whatever?size=2000000" ...>
<filesystemType>fake</filesystemType>
This will create a filesystem filled with 2TB of random data that can be
scanned and synced. There are more options, see fakefs.go.
Prefilled data is based on a deterministic seed, so you can index the
data and restart Syncthing and the index is still correct for all the
stored data.
The previous "Bad Request" was really confusing as it implies it's
somethign wrong with the request, which there isn't - the problem is
that server configuration forbids the request.
This removes the user and group juggling, which would fail when given
for example a PGID that already existed as the "syncthing" group could
then not be created with that PGID. It's not reasonable to expect the
user to know which group/user names/IDs are already present in the
Docker image.
Instead we now just launch under the specified IDs, while manually
setting the HOME env var to give us a home directory - the only thing we
needed the user entry for anyway.
Also updates to Go 1.11 and building without upgrades instead of
disabling by env var.
