68f883ff77 audioconvert: fix dither scale 
Rectangular dither should be [-0.5, 0.5]
Triangular dither should be [-1.0, 1.0]
Noise should add extra bits.

9b37142ef6 audioconvert: implement noise shaping 
To compare the results:

  pw-cat -r test.wav --format=u8 -P '{ dither.method=none }'

vs:

  pw-cat -r test.wav --format=u8 -P '{ dither.method=shaped5 }'

938f2b123e audioconvert: improve format conversion 
Make dither noise as a value between -0.5 and 0.5 and add this
to the scaled samples.
For this, we first need to do the scaling and then the CLAMP to
the target depth. This optimizes to the same code but allows us
to avoid under and overflows when we add the dither noise.

Add more dithering methods.

Expose a dither.method property on audioconvert. Disable dither when
the target depth > 16.

6b49bded3a audioconvert: move dither and noise to fmt-ops 
We need to do dithering and noise when converting f32 to the
target format. This is more natural because we can work in 32 bits
integers instead of floats.

This will also make it possible to actually calculate the error between
source and target values and implement some sort of feedback and
noise shaping later.

iteration as the strided stereo deinterleave one.

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.

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.
