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.

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.

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

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

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.
