* Add a per-room mutex to federationapi when processing transactions
This has numerous benefits:
- Prevents us doing lots of state resolutions in busy rooms. Previously, room forks would always result
in a state resolution being performed immediately, without checking if we were already doing this in
a different transaction. Now they will queue up, resulting in fewer calls to `/state_ids`, `/g_m_e`, etc.
- Prevents memory usage from growing too large as a result and potentially OOMing.
And costs:
- High traffic rooms will be slightly slower due to head-of-line blocking from other servers,
though this has always been an issue as roomserver has a per-room mutex already.

* nolint
* 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
* Use background context when processing event with missing state
* Five minute timeout
* Remove context from txnreq, thread through instead

* Use transaction origin, update whitelist
* Fix federation API test
It's sufficient for us to return nothing in response to current state, so that the server ACL check returns no ACLs.

* Replace publicroomsapi with a combination of clientapi/roomserver/currentstateserver
- All public rooms paths are now handled by clientapi
- Requests to (un)publish rooms are sent to the roomserver via `PerformPublish`
which are stored in a new `published_table.go`
- Requests for public rooms are handled in clientapi by:
* Fetch all room IDs which are published using `QueryPublishedRooms` on the roomserver.
* Apply pagination parameters to the slice.
* Do a `QueryBulkStateContent` request to the currentstateserver to pull out
required state event *content* (not entire events).
* Aggregate and return the chunk.
Mostly but not fully implemented (DB queries on currentstateserver are missing)
* Fix pq query
* Make postgres work
* Make sqlite work
* Fix tests
* Unbreak pagination tests
* Linting
* Add PerformInvite and refactor how errors get handled
- Rename `JoinError` to `PerformError`
- Remove `error` from the API function signature entirely. This forces
errors to be bundled into `PerformError` which makes it easier for callers
to detect and handle errors. On network errors, HTTP clients will make a
`PerformError`.
* Unbreak everything; thanks Go!
* Send back JSONResponse according to the PerformError
* Update federation invite code too
* Fix rooms v3 url paths for good - with tests
- Add a test rig around `federationapi` to test routing.
- Use `JSONVerifier` over `KeyRing` so we can stub things out more easily.
- Add `test.NopJSONVerifier` which verifies nothing.
- Add `base.BaseMux` which is the original `mux.Router` used to spawn public/internal routers.
- Listen on `base.BaseMux` and not the default serve mux as it cleans paths which we don't want.
- Factor out `ListenAndServe` to `test.ListenAndServe` and add flag for listening on TLS.
* Fix comments
* Linting
* Minor perf/debugging improvements
- publicroomsapi: Don't call QueryEventsByID with no event IDs
- appservice: Consume only if there are 1 or more ASes
- roomserver: don't keep a copy of the request "for debugging" - we trace now
* fedsender: return early if we have no destinations
* Unbreak tests
* s/QueryBackfill/PerformBackfill/g
* OutputEvent now includes AddStateEvents which contain the full event of extra state events
* Only include adds not the current event
* Get adding state right
* Remove clientapi producers which aren't actually producers
They are actually just convenience wrappers around the internal APIs
for roomserver/eduserver. Move their logic to their respective `api`
packages and call them directly.

Specifically I think it's
4172585c25/lib/SyTest/Federation/Client.pm (L265)
to blame here.
* only send new events to RS; add tests for /state_ids and /event
* Review comments: send in auth event order
* Ignore order of state events for this test as RespState.Events is non-deterministic
