Fix error handling for rooms whose versions are unknown. (#5219) 
If we remove support for a particular room version, we should behave more
gracefully. This should make client requests fail with a 400 rather than a 500,
and will ignore individiual PDUs in a federation transaction, rather than the
whole transaction.

Collect room-version variations into one place (#4969) 
Collect all the things that make room-versions different to one another into
one place, so that it's easier to define new room versions.

840068bd78 Only check event ID domain for signatures for V1 events 
In future version events won't have an event ID, so we won't be able to
do this check.

8e3d34e3c5 Use event origin for filtering incoming events 
We only process events sent to us from a server if the event ID matches
the server, to help guard against federation storms. We replace this
with a check against the event origin.

6598992b01 Fixup calls to comput_event_signature 
We currently pass FrozenEvent instead of `dict` to
`compute_event_signature`, which works by accident due to `dict(event)`
producing the correct result.

This fixes PR #4493 commit 855a151

9417986f77 Drop PDUs of unknown rooms 
When we receive events over federation we will need to know the room
version to be able to correctly handle them, e.g. once we start changing
event formats. Currently, we attempt to handle events in unknown rooms.

ef771cc4c2 Fix a number of flake8 errors 
Broadly three things here:

* disable W504 which seems a bit whacko
* remove a bunch of `as e` expressions from exception handlers that don't use
  them
* use `r""` for strings which include backslashes

Also, we don't use pep8 any more, so we can get rid of the duplicate config
there.

fc0f13dd03 Fix incorrect truncation in get_missing_events 
It's quite important that get_missing_events returns the *latest* events in the
room; however we were pulling event ids out of the database until we got *at
least* 10, and then taking the *earliest* of the results.

We also shouldn't really be relying on depth, and should be checking the
room_id.

Include eventid in log lines when processing incoming federation transactions (#3959) 
when processing incoming transactions, it can be hard to see what's going on,
because we process a bunch of stuff in parallel, and because we may end up
recursively working our way through a chain of three or four events.

This commit creates a way to use logcontexts to add the relevant event ids to
the log lines.

703de4ec13 Comments and interface cleanup for on_receive_pdu 
Add some informative comments about what's going on here.

Also, `sent_to_us_directly` and `get_missing` were doing the same thing (apart
from in `_handle_queued_pdus`, which looks like a bug), so let's get rid of
`get_missing` and use `sent_to_us_directly` consistently.

0a65450d04 Validation for events/rooms in fed requests

said event is in the room the caller claims it is in.
