In state res v2, we apply two passes of iterative auth checks. The first
pass replays power events and events in their auth chains, but only
those belonging to the full conflicted set. The source code as written
suggests that we want only those belonging to the auth difference (which
is a smaller set of events).
At runtime we were doing the correct thing anyway, because the only
callsite of `_reverse_topological_power_sort` passes in the
`full_conflicted_set`. So this really is just a rename.
This adds support for the stable identifiers of MSC2285 while
continuing to support the unstable identifiers behind the configuration
flag. These will be removed in a future version.
Fix @tag_args being off-by-one (ahead)
Example:
```
argspec.args=[
'self',
'room_id'
]
args=(
<synapse.storage.databases.main.DataStore object at 0x10d0b8d00>,
'!HBehERstyQBxyJDLfR:my.synapse.server'
)
```
---
The previous logic was also flawed and we can end up in a situation like this:
```
argspec.args=['self', 'dest', 'room_id', 'limit', 'extremities']
args=(<synapse.federation.federation_client.FederationClient object at 0x7f1651c18160>, 'hs1', '!jAEHKIubyIfuLOdfpY:hs1')
```
From this source:
```py
async def backfill(
self, dest: str, room_id: str, limit: int, extremities: Collection[str]
) -> Optional[List[EventBase]]:
```
And this usage:
```py
events = await self._federation_client.backfill(
dest, room_id, limit=limit, extremities=extremities
)
```
which would previously cause this error:
```

* Adds docstrings and inline comments.
* Formats SQL queries using triple quoted strings.
* Minor formatting changes.
* Avoid fetching `event_push_summary_stream_ordering` multiple times
in the same transactions.
Still maintains local in memory lookup optimisation, but does any external
lookup as part of the deferred that prevents duplicate lookups for the same
event at once. This makes the assumption that fetching from an external
cache is a non-zero load operation.
Part of my continuing quest to make the docker images build quicker: copy nginx and redis in from base docker images, rather than apt installing each time.

Previously, `_resolve_state_at_missing_prevs` returned the resolved
state before an event and a partial state flag. These were unwieldy to
carry around would only ever be used to build an event context. Build
the event context directly instead.
