03751a6420 Fix some looping_call calls which were broken in #3604 
It turns out that looping_call does check the deferred returned by its
callback, and (at least in the case of client_ips), we were relying on this,
and I broke it in #3604.

Update run_as_background_process to return the deferred, and make sure we
return it to clock.looping_call.

these reqeusts to master, so that we can move federation APIs to

1be94440d3 Fix occasional 'tuple index out of range' error 
This fixes a bug in _delete_existing_rows_txn which was introduced in #3435
(though it's been on matrix-org-hotfixes for *years*). This code is only called
when there is some sort of conflict the first time we try to persist an event,
so it only happens rarely. Still, the exceptions are annoying.

ec56121b0d Correctly handle outliers during persist events 
We incorrectly asserted that all contexts must have a non None state
group without consider outliers. This would usually be fine as the
assertion would never be hit, as there is a shortcut during persistence
if the forward extremities don't change.

However, if the outlier is being persisted with non-outlier events, the
function would be called and the assertion would be hit.

Fixes #3601

8b8c4f34a3 Replace usage of get_current_toke with StreamToken.START 
This allows us to handle /context/ requests on the client_reader worker
without having to pull in all the various stream handlers (e.g.
precence, typing, pushers etc). The only thing the token gets used for
is pagination, and that ignores everything but the room portion of the
token.

5c705f70c9 Fixes and optimisations for resolve_state_groups 
First of all, fix the logic which looks for identical input state groups so
that we actually use them. This turned out to be most easily done by factoring
the relevant code out to a separate function so that we could do an early
return.

Secondly, avoid building the whole `conflicted_state` dict (which was only ever
used as a boolean flag).

Thirdly, replace the construction of the `state` dict (which mapped from keys
to events that set them), with an optimistic construction of the resolution
result assuming there will be no conflicts. This should be no slower than
building the old `state` dict, and:
  - in the conflicted case, we'll short-cut it, saving part of the work
  - in the unconflicted case, it saves rebuilding the resolution from the
    `state` dict.

Finally, do a couple of s/values/itervalues/.

This is more involved than it might otherwise be, because the current
implementation just drops its logcontexts and runs everything in the sentinel
context.

It turns out that we aren't actually using a bunch of the functionality here
(notably suppress_failures and the fact that Distributor.fire returns a
deferred), so the easiest way to fix this is actually by simplifying a bunch of
code.

6e3fc657b4 Resource tracking for background processes 
This introduces a mechanism for tracking resource usage by background
processes, along with an example of how it will be used.

This will help address #3518, but more importantly will give us better insights
into things which are happening but not being shown up by the request metrics.

We *could* do this with Measure blocks, but:
 - I think having them pulled out as a completely separate metric class will
   make it easier to distinguish top-level processes from those which are
   nested.

 - I want to be able to report on in-flight background processes, and I don't
   think we want to do this for *all* Measure blocks.

The get_entities_changed function was changed to return all changed
entities since the given stream position, rather than only those changed
from a given list of entities. This resulted in the function incorrectly
returning large numbers of entities that, for example, caused large
increases in database usage.

77b692e65d Don't return unknown entities in get_entities_changed 
The stream cache keeps track of all entities that have changed since
a particular stream position, so get_entities_changed does not need to
return unknown entites when given a larger stream position.

This makes it consistent with the behaviour of has_entity_changed.

fa5c2bc082 Reduce set building in get_entities_changed 
This line shows up as about 5% of cpu time on a synchrotron:

    not_known_entities = set(entities) - set(self._entity_to_key)

Presumably the problem here is that _entity_to_key can be largeish, and
building a set for its keys every time this function is called is slow.

Here we rewrite the logic to avoid building so many sets.

5797f5542b WIP to announce deleted devices over federation 
Previously we queued up the poke correctly when the device was deleted,
but then the actual EDU wouldn't get sent, as the device was no longer known.
Instead, we now send EDUs for deleted devices too if there's a poke for them.

36f4fd3e1e Comment dummy TURN parameters in default config 
This default config is parsed and used a base before the actual
config is overlaid, so with these values not commented out, the
code to detect when no turn params were set and refuse to generate
credentials was never firing because the dummy default was always set.
