SYN-287
This requires that HS owners either opt in or out of stats reporting.
When --generate-config is passed, --report-stats must be specified
If an already-generated config is used, and doesn't have the
report_stats key, it is requested to be set.
A couple of weird caveats:
* If we can't validate your macaroon, we fall back to checking that
your access token is in the DB, and ignoring the failure
* Even if we can validate your macaroon, we still have to hit the DB to
get the access token ID, which we pretend is a device ID all over the
codebase.
This mostly adds the interesting code, and points out the two pieces we
need to delete (and necessary conditions) in order to fix the above
caveats.
Removes device_id and ClientInfo
device_id is never actually written, and the matrix.org DB has no
non-null entries for it. Right now, it's just cluttering up code.
This doesn't remove the columns from the database, because that's
fiddly.
This allows refresh tokens to be exchanged for (access_token,
refresh_token).
It also starts issuing them on login, though no clients currently
interpret them.
This just replaces random bytes with macaroons. The macaroons are not
inspected by the client or server.
In particular, they claim to have an expiry time, but nothing verifies
that they have not expired.
Follow-up commits will actually enforce the expiration, and allow for
token refresh.

V2 Registration forced everyone (including ASes) to create a password for a
user, when ASes should be able to omit passwords. Also unbreak AS registration
in general which checked too early if the given username was claimed by an AS;
it was checked before knowing if the AS was the one doing the registration! Add
unit tests for AS reg, user reg and disabled_registration flag.
Bug introduced in 92b20713d7
which reversed the comparison when checking if a user existed
in the users table. Added UTs to prevent this happening again.
