More hacking Add connection message for PORT_COMMAND Add rtkit support to ask for realtime priority work on stream states and improve negotiation Rework of port linking works, keep separate state for realtime threads and use message passing to update the state. Don't try to link nodes that are removed. Open the device in the ALSA monitor to detect source or sink Implement send_command as async methods on the plugins, use async replies to sync start and stop. Work on alsa sink. Implement async PAUSE/START on v4l2 src. move the STREAMON/OFF calls to the mainloop because they have high latency, add the poll descriptors from the data loop.
