Fix integer overflow in device_list_update.go (#1717)
Fix #1511
On 32-bits systems, int(hash.Sum32()) can be negative.
This makes the computation of array indices using modulo invalid, crashing dendrite.

Only emit key changes which are different from what we had before (#1279)
We did this already for local `/keys/upload` but didn't for
remote `/users/devices`. This meant any resyncs would spam produce
events, hammering disk i/o and spamming the logs.

Make 'Device list doesn't change if remote server is down' pass (#1268)
- As a last resort, query the DB when exhausting all possible remote query
  endpoints, but keep the field in `failures` so clients can detect that this
  is stale data.
- Unblock `DeviceListUpdater.Update` on failures rather than timing out.
- Use a mutex when writing directly to `res`, not just for failures.

Fix more E2E sytests (#1265)
* WIP: Eagerly sync device lists on /user/keys/query requests

Also notify servers when a user's device display name changes. Few
caveats:
 - sytest `Device deletion propagates over federation` fails
 - `populateResponseWithDeviceKeysFromDatabase` is called from multiple
   goroutines and hence is unsafe.

* Handle deleted devices correctly over federation

Add sync mechanism to block when updating device lists (#1264)
* Add sync mechanism to block when updating device lists

With a timeout, mainly for sytest to fix the test
"Server correctly handles incoming m.device_list_update"
which is flakey because it assumes that when `/send` 200 OKs
that the server has updated the device lists in prep for
`/keys/query` which is not always true when using workers.

* Fix UT

* Add new working test
