Enforce validity period on server_keys for fed requests. (#5321)
When handling incoming federation requests, make sure that we have an
up-to-date copy of the signing key.

We do not yet enforce the validity period for event signatures.

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.

6a41d2a187 Add room_version param to get_pdu
When we add new event format we'll need to know the event format or room
version when parsing events.

89a76d1889 Fix handling of redacted events from federation
If we receive an event that doesn't pass their content hash check (e.g.
due to already being redacted) then we hit a bug which causes an
exception to be raised, which then promplty stops the event (and
request) from being processed.

This effects all sorts of federation APIs, including joining rooms with
a redacted state event.

804dd41e18 Check that signatures on events are valid
We should check that both the sender's server, and the server which created the
event_id (which may be different from whatever the remote server has told us
the origin is), have signed the event.

3366b9c534 rename assert_params_in_request to assert_params_in_dict
the method "assert_params_in_request" does handle dicts and not
requests. A request body has to be parsed to json before this method
can be used

33f469ba19 Apply some limits to depth to counter abuse
* When creating a new event, cap its depth to 2^63 - 1
* When receiving events, reject any without a sensible depth

fcf2c0fd1a Remove redundant preserve_fn
preserve_fn is a no-op unless the wrapped function returns a
Deferred. verify_json_objects_for_server returns a list, so this is doing
nothing.
