Do not assume that account data is of the correct form. (#8454)
This fixes a bug where `m.ignored_user_list` was assumed to be a dict,
leading to odd behavior for users who set it to something else.

8e64c5a24c filter out m.room.aliases from the CS API until a better solution is specced (#6878)
We're in the middle of properly mitigating spam caused by malicious aliases being added to a room. However, until this work fully lands, we temporarily filter out all m.room.aliases events from /sync and /messages on the CS API, to remove abusive aliases. This is considered acceptable as m.room.aliases events were never a reliable record of the given alias->id mapping and were purely informational, and in their current state do more harm than good.

Discard retention policies when retrieving state
Purge jobs don't delete the latest event in a room in order to keep the forward extremity and not break the room. On the other hand, get_state_events, when given an at_token argument calls filter_events_for_client to know if the user can see the event that matches that (sync) token. That function uses the retention policies of the events it's given to filter out those that are too old from a client's view.

Some clients, such as Riot, when loading a room, request the list of members for the latest sync token it knows about, and get confused to the point of refusing to send any message if the server tells it that it can't get that information. This can happen very easily with the message retention feature turned on and a room with low activity so that the last event sent becomes too old according to the room's retention policy.

An easy and clean fix for that issue is to discard the room's retention policies when retrieving state.

Don't apply retention policy based filtering on state events
As per MSC1763, 'Retention is only considered for non-state events.', so don't filter out state events based on the room's retention policy.

d1523aed6b Only check history visibility when filtering
When filtering events to send to server we check more than just history
visibility. However when deciding whether to backfill or not we only
care about the history visibility.

Refactor state group lookup to reduce DB hits (#4011)
Currently when fetching state groups from the data store we make two
hits two the database: once for members and once for non-members (unless
request is filtered to one or the other). This adds needless load to the
datbase, so this PR refactors the lookup to make only a single database
hit.

495975e231 Optimisation for filter_events_for_server
We're better off hashing just the event_id than the whole ((type, state_key),
event_id) tuple - so use a dict instead of a set.

Also, iteritems > items.
