alsa: disable pause-on-idle by default
...
snd_pcm_drop() causes pops and cracks. It is better to just let the
sink consume silence until it gets suspended.

node: Add ParamBegin/End
...
Use these commands to mark the begin and end of a series of Param
enumerations and configuration, like when doing format negotiation. The
idea is that the device can remain open while we do this.
Use this in adapter when negotiating a format.

alsa: fix buffer recycle
...
We only set the OUT flag when we put the buffer on an io area and
might need to recycle later.
Before placing the output buffer into the io area, recycle any
buffer that might be left in there.
Only emit the ready callback when we have some data queued.

Make interface types a string
...
This is more in line with wayland and it allows us to create new
interfaces in modules without having to add anything to the type
enum. It also removes some lookups to map type_id to readable
name in debug.

clock, disable rate matching.
