This will allow us to easily add an internal replication API to proxy
these reqeusts to master, so that we can move federation APIs to
workers.

30848c0fcd Ignore incoming events for rooms that we have left
When synapse receives an event for a room its not in over federation, it
double checks with the remote server to see if it is in fact in the
room. This is done so that if the server has forgotten about the room
(usually as a result of the database being dropped) it can recover from
it.

However, in the presence of state resets in large rooms, this can cause
a lot of work for servers that have legitimately left. As a hacky
solution that supports both cases we drop incoming events for rooms that
we have explicitly left.

This means that we no longer support the case of servers having
forgotten that they've rejoined a room, but that is sufficiently rare
that we're not going to support it for now.

0cdb32fc43 Remove redundant try/except clauses
The `except SynapseError` clauses were pointless because the wrapped functions
would never throw a `SynapseError` (they either throw a `CodeMessageException`
or a `RuntimeError`).

The `except CodeMessageException` is now also pointless because the caller
treats all exceptions equally, so we may as well just throw the
`CodeMessageException`.

64765e5199 When we do an invite rejection, save the signed leave event to the db
During a rejection of an invite received over federation, we ask a remote
server to make us a `leave` event, then sign it, then send that with
`send_leave`.

We were saving the *unsigned* version of the event (which has a different event
id to the signed version) to our db (and sending it to the clients), whereas
other servers in the room will have seen the *signed* version. We're not aware
of any actual problems that caused, except that it makes the database confusing
to look at and generally leaves the room in a weird state.

9ce53a3861 Queue up federation PDUs while a room join is in progress
This just takes the existing `room_queues` logic and moves it out to
`on_receive_pdu` instead of `_process_received_pdu`, which ensures that we
don't start trying to fetch prev_events and whathaveyou until the join has
completed.

29235901b8 Move FederationServer._handle_new_pdu to FederationHandler
Unfortunately this significantly increases the size of the already-rather-big
FederationHandler, but the code fits more naturally here, and it paves the way
for the tighter integration that I need between handling incoming PDUs and
doing the join dance.

Other than renaming the existing `FederationHandler.on_receive_pdu` to
`_process_received_pdu` to make way for it, this just consists of the move, and
replacing `self.handler` with `self` and `self` with `self.replication_layer`.

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.

This works around a bug where if we make a backfill request with too
many extremeties it causes the request URI to be too long.
