Distinguish 'client' from 'federation' events (#3658)
Fixes #3305 
Fixes #3380
 
The idea here is to better distinguish between a 'raw' event (as we send over the wire), and the 
'serialised' format, as sent in responses to the C-S api and in `PUT /_matrix/app/v1/transactions/{txnId}`.

It's made more complicated by the fact that there are _two_ serialisation formats, one used by `/sync`
and `/notifications`, and one by everything else (the difference being whether `room_id` is included).

In an ideal world, we wouldn't repeat `SerialisedEvent` every time it's used, and instead just link to the
first reference, but that's a job for another day.

Another job for another day is to get rid of things like `sync_state_event.yaml` (which is now used
only in one place, so should be inlined.)

summary: Get events and state around the specified event.
description: |-
This API returns a number of events that happened just before and
after the specified event. This allows clients to get the context
surrounding an event.
*Note*: This endpoint supports lazy-loading of room member events. See
[Lazy-loading room members](/client-server-api/#lazy-loading-room-members) for more information.

type: string
description: |-
A JSON `RoomEventFilter` to filter the returned events with. The
filter is only applied to `events_before`, `events_after`, and
`state`. It is not applied to the `event` itself. The filter may
be applied before or/and after the `limit` parameter - whichever the
homeserver prefers.
See [Filtering](/client-server-api/#filtering) for more information.
