* Check for missing state keys to avoid panicking
* Check for not allowed errors on send_leave
* More logging
* handle send_join errors too
* Additional send_join checks
* s/join/gmsl.json/
* Add notary server tables for postgres
* Add sqlite tables
* fedsender: GetServerKeys -> QueryServerKeys
As it now checks a cache and can return multiple responses
* bugfix: retire invites even when we cannot talk to the remote server to make/send_leave
Also modify the leave response in /sync to include a fake event as this is ultimately
what clients (and sytest) will use to determine leave-ness.
* hash the event ID
* Base64 not hex
* Implement /_synapse/admin/v1/register
This is implemented identically to Synapse, so scripts which work
with Synapse should work with Dendrite.
```
Test 27 POST /_synapse/admin/v1/register with shared secret... OK
Test 28 POST /_synapse/admin/v1/register admin with shared secret... OK
Test 29 POST /_synapse/admin/v1/register with shared secret downcases capitals... OK
Test 30 POST /_synapse/admin/v1/register with shared secret disallows symbols... OK
```
Sytest however has `implementation_specific => "synapse"` which stops these
tests from running.
