638d35ef08 Fix linearizer cancellation on twisted < 18.7
Turns out that cancellation of inlineDeferreds didn't really work properly
until Twisted 18.7. This commit refactors Linearizer.queue to avoid
inlineCallbacks.

7c712f95bb Combine Limiter and Linearizer
Linearizer was effectively a Limiter with max_count=1, so rather than
maintaining two sets of code, let's combine them.

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.

calls to them and kill them off.

bf993db11c Logging and logcontext fixes for Limiter
Add some logging to the Limiter in a similar spirit to the Linearizer, to help
debug issues.

Also fix a logcontext leak.

Also refactor slightly to avoid throwing exceptions.

4fad8efbfb Fix stackoverflow and logcontexts from linearizer
1. make it not blow out the stack when there are more than 50 things waiting
   for a lock. Fixes https://github.com/matrix-org/synapse/issues/2505.

2. Make it not mess up the log contexts.

1c82fbd2eb Implement create_observer.
`create_observer` takes a deferred and create a new deferred that
*observers* the original deferred. Any callbacks added to the observing
deferred will *not* affect the origin deferred.
