Take the queued input samples into account when calculating the
required input size. This can be 0 when there is still enough
data queued in the input for another period.
Handle 0 read_size in alsa-source and make it push out a 0 buffer,
this will then drain the resampler and make it ask for a new buffer
size. This makes the transition from one period to another more
seamless for the resampler.

Keep track of the param changes with the user counter. Make sure to
flip the serial switch whenever a change is pending. Previously
we copied the param from the channelmixer or follower but that
did not always result in a serial change.
Fixes#764
Keep track of the subelement we're iterating in the result index upper
bits. Use enum_sync to iterate each param and switch to the next
element when we run out of params.

Implement monitor volumes in the merger. There are two volumes,
the channel volume and the monitor volume. The monitor volume
is always applied.
By default the monitor volume will now follow the main volume of
the node. This can be disabled with a monitor.channel-volumes
property.

Clamp position to valid range. so that AUX becomes UNKNOWN.
If we have one mono source channel and unknown destination, copy it
to all destination channels.
If we have one mono destination channel and unknown source layout,
average all channels.
Otherwise, pair source and dest channels.
See #538
Instead of requiring the upstream node to resubmit the delayed
samples, keep the samples ourselves. The benefit is probably too
small to measure but it simplifies things a lot.
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.
We also need to remap channels for the splitter and merger.
Remember the port-config format and its channel layout. Internally,
we use a canonical channel layout which is simply all channels sorted
by id. Remap the channels accordingly.
