Controls the group membership in the current session.
For now, this class implements only a hash table of members, but its design and relation with other classes is intented to support group membership sampling in case scalability problems arise.

The initial size is a hint to allocate the resources needed in order to keep the members' identifiers and associated information.
Although ccRTP will reallocate resources when it becomes necessary, a good hint may save a lot of unpredictable time penalties.

Purges all RTPSource structures created during the session, as well as the hash table and the list of sources.

Mark the source identified by ssrc
as having sent a BYE packet.
It is not deleted until a timeout expires, so that in case some packets from this source arrive a bit later the source is not inserted again in the table of known sources.
