4e7be858e4 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.

441fdb2333 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.

Add a clock name to the clock, remove the old api/clock_id. This makes
it easier to add descriptive names

Place the alsa card number in the clock name.

Check the clock name of the master clock and if it matches our own
clock, disable rate matching.
