Catch-up after Federation Outage (bonus): Catch-up on Synapse Startup (#8322)
Signed-off-by: Olivier Wilkinson (reivilibre) <olivier@librepush.net>

* Fix _set_destination_retry_timings

This came about because the code assumed that retry_interval
could not be NULL — which has been challenged by catch-up.

Use _check_sigs_and_hash_and_fetch to validate backfill requests (#8350)
This is a bit of a hack, as `_check_sigs_and_hash_and_fetch` is intended
for attempting to pull an event from the database/(re)pull it from the
server that originally sent the event if checking the signature of the
event fails.

During backfill we *know* that we won't have the event in our database,
however it is still useful to be able to query the original sending
server as the server we're backfilling from may be acting maliciously.

The main benefit and reason for this change however is that
`_check_sigs_and_hash_and_fetch` will drop an event during backfill if
it cannot be successfully validated, whereas the current code will
simply fail the backfill request - resulting in the client's /messages
request silently being dropped.

This is a quick patch to fix backfilling rooms that contain malformed
events. A better implementation in planned in future.

Put a cache on /state_ids (#7931)
If we send out an event which refers to `prev_events` which other servers in
the federation are missing, then (after a round or two of backfill attempts),
they will end up asking us for `/state_ids` at a particular point in the DAG.

As per https://github.com/matrix-org/synapse/issues/7893, this is quite
expensive, and we tend to see lots of very similar requests around the same
time.

We can therefore handle this much more efficiently by using a cache, which (a)
ensures that if we see the same request from multiple servers (or even the same
server, multiple times), then they share the result, and (b) any other servers
that miss the initial excitement can also benefit from the work.

[It's interesting to note that `/state` has a cache for exactly this
reason. `/state` is now essentially unused and replaced with `/state_ids`, but
evidently when we replaced it we forgot to add a cache to the new endpoint.]

Abort federation requests if the client disconnects early (#7930)
For inbound federation requests, if a given remote server makes too many
requests at once, we start stacking them up rather than processing them
immediatedly.

However, that means that there is a fair chance that the requesting server will
disconnect before we start processing the request. In that case, if it was a
read-only request (ie, a GET request), there is absolutely no point in
building a response (and some requests are quite expensive to handle).

Even in the case of a POST request, one of two things will happen:

 * Most likely, the requesting server will retry the request and we'll get the
   information anyway.

 * Even if it doesn't, the requesting server has to assume that we didn't get
   the memo, and act accordingly.

In short, we're better off aborting the request at this point rather than
ploughing on with what might be a quite expensive request.
