Fix limit logic for AccountDataStream (#7384)
Make sure that the AccountDataStream presents complete updates, in the right
order.

This is much the same fix as #7337 and #7358, but applied to a different stream.

Fix catchup-on-reconnect for the Federation Stream (#7374)
looks like we managed to break this during the refactorathon.

Thread through instance name to replication client. (#7369)
For in memory streams when fetching updates on workers we need to query the source of the stream, which currently is hard coded to be master. This PR threads through the source instance we received via `POSITION` through to the update function in each stream, which can then be passed to the replication client for in memory streams.

Workaround for assertion errors from db_query_to_update_function (#7378)
Hopefully this is no worse than what we have on master...

23b28266ac Remove 'limit' param from get_repl_stream_updates API
there doesn't seem to be much point in passing this limit all around, since
both sides agree it's meant to be 100.

Improve type checking in replication.tcp.Stream (#7291)
The general idea here is to get rid of the type: ignore annotations on all of the current_token and update_function assignments, which would have caught #7290.

After a bit of experimentation, it seems like the least-awful way to do this is to pass the offending functions in as parameters to the Stream constructor. Unfortunately that means that the concrete implementations no longer have the same constructor signature as Stream itself, which means that it gets hard to correctly annotate STREAMS_MAP.

I've also introduced a couple of new types, to take out some duplication.

Fix 'generator object is not subscriptable' error (#7290)
Some of the query functions return generators rather than lists, so we can't
index into the result. Happily we already have a copy of the results.

(think this was introduced in #7024)

Fix race in replication (#7226)
Fixes a race between handling `POSITION` and `RDATA` commands. We do this by simply linearizing handling of them.

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.

Convert *StreamRow classes to inner classes (#7116)
This just helps keep the rows closer to their streams, so that it's easier to
see what the format of each stream is.

9ce4e344a8 Change device list replication to match new semantics.
Instead of sending down batches of user ID/host tuples, send down a row
per entity (user ID or host).

Remove unnecessary parentheses around return statements (#5931)
Python will return a tuple whether there are parentheses around the returned values or not.

I'm just sick of my editor complaining about this all over the place :)

015b3622eb Skip building a ROW_TYPE when building updates
We're about to turn it straight into a JSON object anyway so building a
ROW_TYPE is a bit pointless, and reduces flexibility in the update_function.
