Use stream.current_token() and remove stream_positions() (#7172)
We move the processing of typing and federation replication traffic into their handlers so that `Stream.current_token()` points to a valid token. This allows us to remove `get_streams_to_replicate()` and `stream_positions()`.

Move catchup of replication streams to worker. (#7024)
This changes the replication protocol so that the server does not send down `RDATA` for rows that happened before the client connected. Instead, the server will send a `POSITION` and clients then query the database (or master out of band) to get up to date.

a9b5ea6fc1 Batch cache invalidation over replication
Currently whenever the current state changes in a room invalidate a lot
of caches, which cause *a lot* of traffic over replication. Instead,
lets batch up all those invalidations and send a single poke down
the replication streams.

Hopefully this will reduce load on the master process by substantially
reducing traffic.

6cfee09be9 Make __init__ consitstent across Store heirarchy
Add db_conn parameters to the `__init__` methods of the *Store classes, so that
they are all consistent, which makes the multiple inheritance work correctly
(and so that we can later extract mixins which can be used in the slavedstores)

3a1f3f8388 Change slave storage to use new replication interface
As the TCP replication uses a slightly different API and streams than
the HTTP replication.

This breaks HTTP replication.

75fb9ac1be Add a slaved events store class
Add a test to check that get_room_names_and_aliases does the same
thing on both the master and on the slave data store.
