parentAdd profile data to the room_membership table for joins (diff)
downloadsynapse-52d12ca78232d54f5be516f82e2cebdd8b498516.tar.xz
Add /room/<room_id>/joined_members API
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.
