libpulse: Store pa_stream pointers to hashmaps instead of dynarrays.
Since the stream identifiers (channels) are monotonically growing integer, it isn't a good idea to use them as index to a dynamic array, because the array will grow all the time. This is not a problem with client connections that don't create many streams, but, for example, long-running clients that use libcanberra for playing event sounds, this means that the client connection effectively leaks memory.
