/**
* SECTION:matrix-event-room-aliases
* @short_description: event to list the aliases of a room
*
* This is the default event handler for `m.room.aliases` events.
*
* This event is sent by a homeserver directly to inform of changes to the list of aliases it
* knows about for that room.
*
* The state_key for this event is set to the homeserver which owns the room alias.
*
* The entire set of known aliases for the room is the union of all the `m.room.aliases`
* events, one for each homeserver. Clients should check the validity of any room alias given
* in this list before presenting it to the user as trusted fact. The lists given by this
* event should be considered simply as advice on which aliases might exist, for which the
* client can perform the lookup to confirm whether it receives the correct room ID.
