0185b75381 Change is_host_joined to use current_state table 
This bypasses a bug where using the state groups to figure out if a host
is in a room sometimes errors if the servers isn't in the room. (For
example when the server rejected an invite to a remote room)

aa09d6b8f0 Rip out more refresh_token code 
We might as well treat all refresh_tokens as invalid. Just return a 403 from
/tokenrefresh, so that we don't have a load of dead, untestable code hanging
around.

Still TODO: removing the table from the schema.

1c4f05db41 Stop putting a time caveat on access tokens 
The 'time' caveat on the access tokens was something of a lie, since we weren't
enforcing it; more pertinently its presence stops us ever adding useful time
caveats.

Let's move in the right direction by not lying in our caveats.

1168cbd54d Allow invites via 3pid to bypass sender sig check 
When a server sends a third party invite another server may be the one
that the inviting user registers with. In this case it is that remote
server that will issue an actual invitation, and wants to do it "in the
name of" the original invitee. However, the new proper invite will not
be signed by the original server, and thus other servers would reject
the invite if it was seen as coming from the original user.

To fix this, a special case has been added to the auth rules whereby
another server can send an invite "in the name of" another server's
user, so long as that user had previously issued a third party invite
that is now being accepted.

6a4b650d8a Attempt to validate macaroons 
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.
