Tommi d3b3a3b6bb Remove Call::sync_stream_mapping_
This std::map was used to look up audio streams from ssrcs when
creating/destroying and/or modifying streams. Those operations aren't
frequent enough to justify having a separate lookup map. Removing
the variable, simplifies the thread ownership work a bit.
