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

2a13af23bc Use run_in_background in preference to preserve_fn
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.

Merge pull request #3142 from matrix-org/rav/reraise
reraise exceptions more carefully

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.

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.

639480e14a Avoid creating events with huge numbers of prev_events
In most cases, we limit the number of prev_events for a given event to 10
events. This fixes a particular code path which created events with huge
numbers of prev_events.

05630758f2 Use static JSONEncoders
using json.dumps with custom options requires us to create a new JSONEncoder on
each call. It's more efficient to create one upfront and reuse it.

e3624fad5f Remove pointless ratelimit check
The intention was for the check to be called as early as possible in the

so was fairly pointless.

Unfreeze event before serializing with ujson
In newer versions of https://github.com/esnme/ultrajson, ujson does not
serialize frozendicts (introduced in esnme/ultrajson@53f85b1). Although
the PyPI version is still 1.35, Fedora ships with a build from commit
esnme/ultrajson@2f1d487. This causes the serialization to fail if the
distribution-provided package is used.

This runs the event through the unfreeze utility before serializing it.

Thanks to @ignatenkobrain for tracking down the root cause.

fixes #2351

5a7f561a9b Fix bug where pusherpool didn't start and broke some rooms
Since we didn't instansiate the PusherPool at start time it could fail
at run time, which it did for some users.

This may or may not fix things for those users, but it should happen at
start time and stop the server from starting.
