* WIP Event rejection
* Still send back errors for rejected events
Instead, discard them at the federationapi /send layer rather than
re-implementing checks at the clientapi/PerformJoin layer.
* Implement rejected events
Critically, rejected events CAN cause state resolution to happen
as it can merge forks in the DAG. This is fine, _provided_ we
do not add the rejected event when performing state resolution,
which is what this PR does. It also fixes the error handling
when NotAllowed happens, as we were checking too early and needlessly
handling NotAllowed in more than one place.
* Update test to match reality
* Modify InputRoomEvents to no longer return an error
Errors do not serialise across HTTP boundaries in polylith mode,
so instead set fields on the InputRoomEventsResponse. Add `Err()`
function to make the API shape basically the same.
* Remove redundant returns; linting
* Update blacklist
* Consolidation of roomserver APIs
* Comment out alias tests for now, they are broken
* Wire AS API into roomserver again
* Roomserver didn't take asAPI param before so return to that
* Prevent roomserver asking AS API for alias info
* Rename some files
* Remove alias_test, incoherent tests and unwanted appservice integration
* Remove FS API inject on syncapi component
