Cross-signing validation for self-sigs, expose signatures over /user/keys/query and /user/devices/{userId} (#1962)
* Enable unstable feature again

* Try to verify when a device signs a key

* Try to verify when a key signs a device

* It's the self-signing key, not the master key

* Fix error

* Try to verify master key uploads

* Actually we can't guarantee we can do that so nevermind

* Add signatures into /devices/list request

* Fix nil pointer

* Reprioritise map creation

* Don't skip devices that don't have signatures

* Add some debug logging

* Fix logic error in QuerySignatures

* Fix bugs

* Expose master and self-signing keys on /devices/list hopefully

* maps are tedious

* Expose signatures via /keys/query

* Upload signatures when uploading keys

* Fixes

* Disable the feature again

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

Finish inbound E2E device lists (#1243)
* Add tests for device list updates

* Add stale_device_lists table and use db before asking remote for device keys

* Fetch remote keys if all devices are requested

* Add display_name col to store remote device names

Few other tweaks to make `Server correctly handles incoming m.device_list_update`
pass.

* Fix sqlite otk bug

* Unbuffered channel to block /send causing sytest to not race anymore

* Linting and fix bug whereby we didn't send updated dl tokens to the client causing a tightloop on /sync sometimes

* No longer assert staleness as Update blocks on workers now

* Back out tweaks

* Bugfixes
