354a04c91d Channel mixer: Remove channelmix_f32_2_4_sse 
It does not have PSD upmixing implemented and does not allow to disable
the simple upmixing algorithm either.

Fixes #2438.

66e4334c92 channelmix: reuse more functions 
Make some copy/vol functions and reuse them.
Reuse the 2->3p1 upmix code, tweak it a little to that the widen
param is always used.

bc5b486cb9 channelmix: add simple upmix method 
Add a property to select the upmix method. PSD is enabled by default
but a new simple upmixing algorithm is available that duplicates
channels and avoids lowpass filter on the FC and disables widening.

Fixes #861

23db50630d channelmix: add option to filter FC 
Add an option to do a lowpass filter on the FC channel to isolate
the voices better and move the higher frequencies to the stereo
channels.

See #861

5b3388e4ac audioconvert: add optional hilbert transform to rear channels 
Add an option to do a hilbert transform on the generated rear channels
to do a 90 degree pahse shift on them. This can improve spacialization
of the rear channels.

See #861

5dd0a12875 channelmix: add option for stereo widen 
When generating FC, add an option to subtract some of the generated
FC from the FL and FR channel to move the sound more to the center.

See #861

92198e4d0d spa: clamp required alignment to cpu alignment 
pipewire will allocate buffers aligned to the max alignment required for
the CPU. Take this into account and don't expect larger alignment.

Fixes a warning in mixer-dsp when the CPU max alignment is 16 but the
plugin requires 32 bytes alignment for the AVX2 path (that would never
be chosen on the CPU).

See #2074

6b34b8c44e audioconvert: fix mono channel mix test 
When we have a single MONO channel, distribute and average. Otherwise,
use the logic to do proper mixing.

Adjust the unit test accordingly.

5724093343 audioconvert: run lr4 on tagged channels in generic case 
Mark the LFE channels and run the lowpass filter on them in
the generic case. Generates LFE correctly in 2.1 upmix case.

14e8073d18 audioconvert: add LFE filter

e51cc5b537 channelmix: Prepare for generating LFE channel

6324298bc5 channelmix: add more generic upmixing 
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.

9a7cbeea83 channelmix: improve undefined channel layout 
When we have no channel layout, just copy input to output
channel.
Optimize this case in the mixer implementation.

f7d8fef070 channelmix: normalize volumes 
Normalize the volumes.

Move some booleans to flags
Improve some checks for fastpaths.

c6a7b3eedb channelmix: implement per channel volume 
Implement per channel volume on channelmix. Extend control on stream to
take an array of values when possible.

Remove name argument from pw_node_new and pw_device_new. We can pass
this as a property instead.

Improve properties on nodes to more closely match what pulseaudio does.
Don't let the monitor do too much with the udev properties but let the
session manager set the description and icon-names.

Remove some change_mask flags for things that don't change in
introspect. Use the flags to mark changes in -cli and -monitor.

d8e399dee9 audioconvert: pass state to functions 
Pass some state to convert and channelmix functions. This makes it
possible to select per channel optimized convert functions but
also makes it possible to implement noise shaping later.
Pass the channelmix matrix and volume in the state.
Handle specialized 2 channel s16 -> f32 conversion
