When the GUI/API is bound to localhost, we enforce that the Host header
looks like localhost. This can be disabled by setting
insecureSkipHostCheck in the GUI config.

Furthermore:
1. Cleans configs received, migrates them as we receive them.
2. Clears indexes of devices we no longer share the folder with

This adds a config to enable debug functions on the API server, which is
by default disabled. When enabled, the /rest/debug things become
available and become available without requiring a CSRF token (although
authentication is required if configured).
We also add a new endpoint /rest/debug/cpuprof?duration=15s (with the
duration being configurable, defaulting to 30s). This runs a CPU profile
for the duration and returns it as a file. It sets headers so that a
browser will save the file with an informative name.
The same is done for heap profiles, /rest/debug/heapprof, which does not
take any parameters.
The purpose of this is that any user can enable debugging under
advanced, then point their browser to the endpoint above and get a file
that contains a CPU or heap profile we can use, with the filename
telling us what version and architecture the profile is from.
On the command line, this becomes
curl -O -J http://localhost:8082/rest/debug/cpuprof?duration=5s
curl: Saved to filename
'syncthing-cpu-darwin-amd64-v0.14.3+4-g935bcc0-110307.pprof'

This slightly changes the interface used for committing configuration
changes. The two parts are now:
- VerifyConfiguration, which runs synchronously and locked, and can
abort the config change. These callbacks shouldn't *do* anything
apart from looking at the config changes and saying yes or no. No
change from previously.
- CommitConfiguration, which runs asynchronously (one goroutine per
call) *after* replacing the config and releasing any locks. Returning
false from these methods sets the "requires restart" flag, which now
lives in the config.Wrapper.
This should be deadlock free as the CommitConfiguration calls can take
as long as they like and can wait for locks to be released when they
need to tweak things. I think this should be safe compared to before as
the CommitConfiguration calls were always made from a random background
goroutine (typically one from the HTTP server), so it was always
concurrent with everything else anyway.
Hence the CommitResponse type is gone, instead you get an error back on
verification failure only, and need to explicitly check
w.RequiresRestart() afterwards if you care.
As an added bonus this fixes a bug where we would reset the "requires
restart" indicator if a config that did not require restart was saved,
even if we already were in the requires-restart state.

This contains the following behavioral changes:
- Duplicate folder IDs is now fatal during startup
- Invalid folder flags in the ClusterConfig is fatal for the connection
(this will go away soon with the proto changes, as we won't have any
unknown flags any more then)
- Empty path is a folder error reported at runtime

The various path cleaning operations done in in cleanedPath() removes
it, so we make sure it's added again at the end. This makes adding the
slash in prepare() unnecessary, but keep it anyway for display purposes
(people looking at the config).

The intention for this package is to provide a combination of the
security of crypto/rand and the convenience of math/rand. It should be
the first choice of random data unless ultimate performance is required
and the usage is provably irrelevant from a security standpoint.

The VersioningConfig change is because it defaults to nil but gets
deserialized to map[string]string{}. Now prepare() enforces a single
representation of the empty map.

Because json.NewDecoder(r).Decode(&v) doesn't necessarily consume all
data on the reader, that means an HTTP connection can't be reused. We
don't do a lot of HTTP traffic where we read JSON responses, but the
discovery is one such place. The other two are for POSTs from the GUI,
where it's not exactly critical but still nice if the connection still
can be keep-alive'd after the request as well.
Also ensure that we call req.Body.Close() for clarity, even though this
should by all accounts not really be necessary.

1. Removes separate relay lists and relay clients/services, just makes it a listen address
2. Easier plugging-in of other transports
3. Allows "hot" disabling and enabling NAT services
4. Allows "hot" listen address changes
5. Changes listen address list with a preferable "default" value just like for discovery
6. Debounces global discovery announcements as external addresses change (which it might alot upon starting)
7. Stops this whole "pick other peers relay by latency". This information is no longer available,
but I don't think it matters as most of the time other peer only has one relay.
8. Rename ListenAddress to ListenAddresses, as well as in javascript land.
9. Stop serializing deprecated values to JSON
