This class contains a description of a stream. It is used for the bandwidth manager's remapping algorithm.
This class realizes synchronized access to a thread's data by other threads. Synchronization is done by using a global pthread mutex and obtaining access to this mutex by synchronized() for synchronized access and releasing this mutex for unsynchronized access. IMPORTANT: Do *not* use synchronized()/unsynchronized() within async signal handlers. This may cause deadlocks. See PThread's pthread_mutex_lock man-page, section "Async Signal Safety" for more information!
