Fix background update that prematurely stopped

Add new API appservice specific public room list

Remove unspecced GET endpoints for e2e keys

GET /keys/claim is a terrible idea, since it isn't idempotent; also it throws
500 errors if you call it without all the right params.

GET /keys/query is arguable, but it's unspecced, so let's get rid of it too to
stop people relying on unspecced APIs.

Update the readme to use trial

Limit the number of events that can be created on a given room concurrently

E2E key query: handle federation fails

Don't try to run tox from setup.py

Don't fail the whole request if we can't connect to a particular server.

Fix rare notifier bug where listeners dont timeout

Using tox to run the tests is a bad idea, as per the comments.

When 546ec1a5 was merged into develop, I accidentally overwrote the change
introduced in debbea5b (pr #1657). Reintroduce it.

There was a race condition that caused the notifier to 'miss' the
timeout notification, since there were no other checks for the timeout
this caused listeners to get stuck in a loop until something happened.

Add new room membership APIs

This returns the currently joined members in the room with their display
names and avatar urls. This is more efficient than /members for large
rooms where you don't need the full events.

Read-receipt fixes

Don't ignore read-receipts which arrive in the same EDU as a read-receipt for
an old event.

This should fix the absence of notifications when new receipts arrive.

Add README instructions for OpenBSD installation
