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

d260cb19be audioconvert: compile c version separately

flags.

0505f2dc98 audioconvert: implement passthrough
Add some const and SPA_RESTRICT to methods
When the input and output is the same, work in passthrough mode
where we simply copy place the input pointer onto the output buffer
without doing a memcpy.
Do memcpy when the resampler is not active.

13bf70a8dd mem: align memory to requested alignment
Improve the allocators to always align the buffer memory to the
requested alignment
Use aligned read and writes for sse functions and check alignment,
optionally falling back to unaligned path.
Add more tests and benchmark cases
Check and warn for misaligned memory in plugins.

6e6e87223f channelmix: improve mute/volume handling
Don't try to merge the mute/volume into the matrix but pass the volume
as a separate parameter.
