The alsa sink calls pa_sink_suspend() from the set_port() callback. pa_sink_suspend() can only be called from the main thread, but the set_port() callback was often called from the IO thread. That caused an assertion to be hit in pa_sink_suspend() when switching ports. Another issue was that pa_sink_suspend() called the set_port() callback, and if the callback calls pa_sink_suspend() again recursively, nothing good can be expected from that, so the thread mismatch was not the only problem. This patch moves the mixer syncing logic out of pa_sink/source_suspend() to be handled internally by the alsa sink/source. This removes the recursive pa_sink_suspend() call. This also removes the need to have the mixer_dirty flag in pa_sink/source, so the flag and the pa_sink/source_set_mixer_dirty() functions can be removed. This patch also changes the threading rules of set_port(). Previously it was called sometimes from the main thread and sometimes from the IO thread. Now it's always called from the main thread. When deferred volumes are used, the alsa sink and source still have to update the mixer from the IO thread when switching ports, but the thread synchronization is now handled internally by the alsa sink and source. The SET_PORT messages are not needed any more and can be removed.
