alsa: pause/resume when entering/exiting freewheel
...
When we start freewheeling, pause the device and resume when we
finish freewheel.
In freewheel mode, just discard samples in the sink and produce
silence in the source.

alsa: add start-delay parameters to sink
...
The start-delay adds extra silence to the buffer before starting the
playback. The idea is to have more time to adapt to the device
startup and set the timer more accurately.

Make info parsing a bit easier to read by assigning the key and
value to temporary variables.
Improve the parsing of channelmap using json parser to make it
support more cases.
Add a unit test for channelmap parsing options.

context: make a new node.max-latency property
...
node.latency also influences the pipeline latency in that it can
push the latency above the default value.
node.max-latency, instead, is only used to clamp the final latency
of the pipeline.
