GET parameters::
timeout(int): How long to wait for new events in milliseconds.
limit(int): Maxiumum number of events per room to return.
gap(bool): Create gaps the message history if limit is exceeded to
ensure that the client has the most recent messages. Defaults to
"true".
sort(str,str): tuple of sort key (e.g. "timeline") and direction
(e.g. "asc", "desc"). Defaults to "timeline,asc".
since(batch_token): Batch token when asking for incremental deltas.
set_presence(str): What state the device presence should be set to.
default is "online".
backfill(bool): Should the HS request message history from other
servers. This may take a long time making it unsuitable for clients
expecting a prompt response. Defaults to "true".

filter_*: Filter override parameters.
