* Create and glue ExternalPublicRoomsProvider into the public rooms component
This is how we will link p2p stuff to dendrite proper.
* Use gmsl structs rather than our own
* Implement federated public rooms
- Make thirdparty endpoint r0 so riot-web loads the public room list
* Typo
* Missing callsites
As a response to #638, it seems that POST /publicRooms is already implemented. It is, however, unclear from the code that it is.
Add some comments and change a method name to make this more clear.
