f372de8608 resample: refactor rate match code 
Use the same code to start rate matching so that we get the same
results for passthrough.

a9bf93030e resample: limit input size to max size of empty space 
When flushing use the max size of the empty space, not the
max size of the input buffers, which might be larger.

801bd98233 audioconvert: use preallocated empty buffer to drain 
Avoid calling memset on a large piece of memory when draining
the resampler because it might use up all the allocated time in
our realtime thread. Instead use a prealloced empty buffer.

86cf4ad5a5 audioconvert: keep better track of changed params 
Keep all the children param flags around and use those to decide
if something changed. Also don't change the param flag serial when
we are simply adding a listener.

This should reduce the number of param updates, most notably the
PropInfo that was updated along with the Props on volume changes.

d63f4234ae channelmix: remap volumes

fc044a37af resample: don't copy too much 
When we are in passthrough mode, copy only the min of input and
output size or else we might overread/overwrite.

e095105e57 resample: fix passthrough check 
Only in passthrough we need to just copy input to output. Otherwise
we need to ask the resampler for the conversion size.

Add options to enable lfe filtering and upmix.
Enable upmix by default, lfe is disabled because we don't actually
do a lowpass filter yet.

3af768f124 resample: take into account the number of queued input samples 
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.

44919c83fc audioconvert: keep better track of param changes 
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.

c7b7afa664 audioadapter: fix enum of properties

bits. Use enum_sync to iterate each param and switch to the next
element when we run out of params.

1511f19f70 audioconvert: handle monitor volumes 
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.

6b0abd2057 channelmix: Improve unknown channel layout handling 
Clamp position to valid range. so that AUX becomes UNKNOWN.

to all destination channels.
If we have one mono destination channel and unknown source layout,
average all channels.
Otherwise, pair source and dest channels.
