33f469ba19 Apply some limits to depth to counter abuse 
* When creating a new event, cap its depth to 2^63 - 1
* When receiving events, reject any without a sensible depth

While I was going through uses of preserve_fn for other PRs, I converted places
which only use the wrapped function once to use run_in_background, to avoid
creating the function object.

6493b22b42 reraise exceptions more carefully 
We need to be careful (under python 2, at least) that when we reraise an
exception after doing some error handling, we actually reraise the original
exception rather than anything that might have been raised (and handled) during
the error handling.

605defb9e4 Add missing consumeErrors 
In general we want defer.gatherResults to consumeErrors, rather than having
exceptions hanging around and getting logged as CRITICAL unhandled errors.

9255a6cb17 Improve exception handling for background processes 
There were a bunch of places where we fire off a process to happen in the
background, but don't have any exception handling on it - instead relying on
the unhandled error being logged when the relevent deferred gets
garbage-collected.

This is unsatisfactory for a number of reasons:
 - logging on garbage collection is best-effort and may happen some time after
   the error, if at all
 - it can be hard to figure out where the error actually happened.
 - it is logged as a scary CRITICAL error which (a) I always forget to grep for
   and (b) it's not really CRITICAL if a background process we don't care about
   fails.

So this is an attempt to add exception handling to everything we fire off into
the background.

b78395b7fe Refactor ResponseCache usage 
Adds a `.wrap` method to ResponseCache which wraps up the boilerplate of a
(get, set) pair, and then use it throughout the codebase.

This will be largely non-functional, but does include the following functional
changes:

* federation_server.on_context_state_request: drops use of _server_linearizer
  which looked redundant and could cause incorrect cache misses by yielding
  between the get and the set.
* RoomListHandler.get_remote_public_room_list(): fixes logcontext leaks
* the wrap function includes some logging. I'm hoping this won't be too noisy
  on production.

91ea0202e6 move handling of auto_join_rooms to RegisterHandler 
Currently the handling of auto_join_rooms only works when a user
registers itself via public register api. Registrations via
registration_shared_secret and ModuleApi do not work

This auto_joins the users in the registration handler which enables
the auto join feature for all 3 registration paths.

This is related to issue #2725

8cb44da4aa Fix race in sync when joining room 
The race happens when the user joins a room at the same time as doing a
sync. We fetch the current token and then get the rooms the user is in.
If the join happens after the current token, but before we get the rooms
we end up sending down a partial room entry in the sync.

This is fixed by looking at the stream ordering of the membership
returned by get_rooms_for_user, and handling the case when that stream
ordering is after the current token.
