0a65450d04 Validation for events/rooms in fed requests 
When we get a federation request which refers to an event id, make sure that
said event is in the room the caller claims it is in.

e908b86832 Remove pdu_failures from transactions 
The field is never read from, and all the opportunities given to populate it are not utilized. It should be very safe to remove this.

it doesn't make much sense to use get_persisted_pdu on the receive path: just
get the event straight from the store.

b78395b7fe Refactor ResponseCache usage 
Adds a `.wrap` method to ResponseCache which wraps up the boilerplate of a
(get, set) pair, and then use it throughout the codebase.

This will be largely non-functional, but does include the following functional
changes:

* federation_server.on_context_state_request: drops use of _server_linearizer
  which looked redundant and could cause incorrect cache misses by yielding
  between the get and the set.
* RoomListHandler.get_remote_public_room_list(): fixes logcontext leaks
* the wrap function includes some logging. I'm hoping this won't be too noisy
  on production.

582bd19ee9 Fix 500 error when we get an error handling a PDU 
FederationServer doesn't have a send_failure (and nor does its subclass,
ReplicationLayer), so this was failing.

I'm not really sure what the idea behind send_failure is, given (a) we don't do
anything at the other end with it except log it, and (b) we also send back the
failure via the transaction response. I suspect there's a whole lot of dead
code around it, but for now I'm just removing the broken bit.

6a6cc27aee fed server: process PDUs for different rooms in parallel 
With luck, this will give a real-time improvement when there are many rooms and
the server ends up calling out to fetch missing events.

a6e3222fe5 Fed server: Move origin-check code to _handle_received_pdu 
The response-building code expects there to be an entry in the `results` list
for each entry in the pdu_list, so the early `continue` was messing this
up. That doesn't really matter, because all that the federation client does is
log any errors, but it's pretty poor form.

30bcbf775a Accept join events from all servers 
Make sure that we accept join events from any server, rather than just the
origin server, to make the federation join dance work correctly.

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`.

e8b1721290 Move sig check out of _handle_new_pdu
