Replace some calls to cursor_to_dict
...
cursor_to_dict can be surprisinglh expensive for large result sets, so lets
only call it when we need to.

Avoid resetting state on rejected events
...
When we get a rejected event, give it the same state_group as its prev_event,
rather than no state_group at all.
This should fix https://github.com/matrix-org/synapse/issues/1935 .

Fix bugs in the /keys/changes api
...
* `get_forward_extremeties_for_room` takes a numeric `stream_ordering`. We were
passing a `RoomStreamToken`, which meant that it returned the *current*
extremities, rather than those corresponding to the `from_token`. However:
* `get_state_ids_for_events` required a second ('types') parameter; this meant
that a `TypeError` was thrown and we ended up acting as though there was *no*
prev state.
* `get_state_ids_for_events` actually returns a map from event_id to state
dictionary - just looking up the state keys in it again meant that we acted
as though there was no prev state. We now check if each member's state has
changed since *any* of the extremities.
Also add/fix some comments.

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.

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.
