Erik Johnston 897d57bc58 Change state fetch query for postgres to be faster
It turns out that postgres doesn't like doing a list of OR's and is
about 1000x slower, so we just issue a query for each specific type
seperately.

Mark Haines 2a37467fa1 Use google style doc strings.
pycharm supports them so there is no need to use the other format.

Might as well convert the existing strings to reduce the risk of
people accidentally cargo culting the wrong doc string format.

Erik Johnston 2c86187a1b Don't cache events in _state_group_cache
Instead, simply cache the event ids, relying on the event cache to cache
the actual events.

The problem was that while the state groups cache was limited in the
number of groups it could hold, each individual group could consist of
thousands of events.

Mark Haines 54172924c8 Load the current id in the IdGenerator constructor
Rather than loading them lazily. This allows us to remove all
the yield statements and spurious arguments for the get_next
methods.

It also allows us to replace all instances of get_next_txn with
get_next since get_next no longer needs to access the db.

Richard van der Hoff fddedd51d9 Fix a few race conditions in the state calculation
Be a bit more careful about how we calculate the state to be returned by
/sync. In a few places, it was possible for /sync to return slightly later
state than that represented by the next_batch token and the timeline. In
particular, the following cases were susceptible:

* On a full state sync, for an active room
* During a per-room incremental sync with a timeline gap
* When the user has just joined a room. (Refactor check_joined_room to make it
  less magical)

Also, use store.get_state_for_events() (and thus the existing stategroups) to
calculate the state corresponding to a particular sync position, rather than
state_handler.compute_event_context(), which recalculates from first principles
(and tends to miss some state).
