* Rate limiting changes
This makes the following changes:
* For logged in users, the rate limiting now applies to the device session rather than the remote IP address;
* For non-logged in users, the rate limiting continues to apply to remote address as it does today;
* It is now possible to add user IDs to the `exempt_user_ids` option under `rate_limiting` to exclude bots from rate limiting;
* Admin and appservice users are now exempt from rate limiting by default.
* Fix build with media API
* Fix flakey sytest 'Local device key changes get to remote servers'
* Debug logs
* Remove internal/test and use /test only
Remove a lot of ancient code too.
* Use FederationRoomserverAPI in more places
* Use more interfaces in federationapi; begin adding regression test
* Linting
* Add regression test
* Unbreak tests
* ALL THE LOGS
* Fix a race condition which could cause events to not be sent to servers
If a new room event which rewrites state arrives, we remove all joined hosts
then re-calculate them. This wasn't done in a transaction so for a brief period
we would have no joined hosts. During this interim, key change events which arrive
would not be sent to destination servers. This would sporadically fail on sytest.
* Unbreak new tests
* Linting
* tidy up interfaces
* remove unused GetCreatorIDForAlias
* Add RoomserverUserAPI interface
* Define more interfaces
* Use AppServiceInternalAPI for consistent naming
* clean up federationapi constructor a bit
* Fix monolith in -http mode
* Specify interfaces used by appservice, do half of clientapi
* convert more deps of clientapi to finer-grained interfaces
* Convert mediaapi and rest of clientapi
* Somehow this got missed
* Update to matrix-org/gomatrixserverlib#303
* Use `gomatrixserverlib.Client` for phone-home stats
* Use `gomatrixserverlib.Client` for push notifications
* Use `gomatrixserverlib.Client` for appservices
* Use `gomatrixserverlib.Client` for three-PID invites
* syncapi: use finer-grained interfaces when making the syncapi
* Use specific interfaces for syncapi-roomserver interactions
* Define query access token api for shared http auth code
