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.
