ac4d4582a4 pulse: set mask after completing the operation 
This ensures we first finish all pending operations and then get
notifications of the new events. Brings pactl subscribe in line
with what it does on real PulseAudio.

19c9a55050 pulse: first sync globals, then try operations 
First sync the globals and if no global created new pending operations,
run through the operations. This ensures no operation is run before
all globals have data.

30254977c6 pulse: improve support for !ADJUST_LATENCY streams 
When a stream does not specify ADJUST_LATENCY, use some slightly
different metrics to implement the readable_size. We want the app
to fill as much space as possible. Makes mplayer work and paplay
use the right amount of buffering.

ed1ee3f164 v4l2: detect driver reusing buffers 
Some drivers seem to only use 2 buffers when asked for 16 buffers. We
can see this because the buffer is already queued. In this case, just
use the 2 buffers.

08438903e5 acp: reset soft volume 
When we have accurate enough hardware volume, set the software volume to
1.0. Also fixes the issue of going to 0 volume and then staying silent
until we raise the volume above 1.0.

9f1d84e37c v4l2: in alloc buffer, don't mmap, just pass the fd 
If we can't use EXPBUF, just put the fd and mapoffset in the buffer
memory. This way we can pass the fd to the client and let it mmap .

a79d1fc866 pulse: tweak buffer attributes some more

d2d722efb3 node: add an ASYNC flag 
The flag means that the process function might not complete
synchronously.

We can use this knowledge to improve the adapter. In sync mode we
can pull before scheduling the converter. In async mode we need to
schedule the follower after the converter to get the data ready for
the next iteration.

We can also improve the stream when it is operating async to schedule
a process call when a new buffer is ready to be filled.

This reduces a cycle latency from alsa and improves latency in
pulse.

584ae678c6 audioadapter: improve the processing loop 
Handle the case where the converter in a source needs more output
buffers (-EPIPE). Schedule the follower in that case and try to
run the converter again until we have output or we can't make progress
anymore.

If the converter needs more data, schedule the follower before we
exit the loop with the data. This gives the follower a chance to get
more data asynchronously for the next iteration.

9dc1c3b168 stream: improve the input process loop

reuse and run out of buffers.
