The user directory is filled with users who this server can see are joined to a
world_readable or publically joinable room. We keep a database table up to date
by streaming changes of the current state and recalculating whether users should
be in the directory or not when necessary.
For each user in the directory we also store a room_id which is public and that the
user is joined to. This allows us to ignore history_visibility and join_rules changes
for that user in all other public rooms, as we know they'll still be in at least
one public room.
