afcf0795c4 pcm/Volume: improved dithering
Instead of just adding a rectangular random value before shifting back
to the normal scale, use the existing PcmDither library.

f3bbe4bb1f pcm/Volume: remove optimized i386 assembly
This code is unable to dither.  Until we implement that, let's remove
the code for now.  i386 isn't relevant anymore anyway.

3a666702af pcm/PcmConvert: add AudioFormat parameters

AudioFormat has already been modified, it's now something in between

a788b7e747 PcmConvert: fix src_format corruption when converting from DSD
Method PcmConvert::Convert() modifies the src_format variable.  This
used to be a parameter, however commit d2679f59c made it an attribute
instead.  The modification to src_format persisted, and the next call
would return garbage.

fc7d5b055d PcmResampleLibsamplerate: clip 24 bit data
Using pcm_resample_lsr_32() for 24 bit samples works, but may cause 24

clipping.

105b431e4c PcmBuffer: reset size in Clear()
Fix for Mantis #3806.

"PcmBuffer::Clear clears the buffer but does not reset the size. If
Get is called on the same PcmBuffer later on with a size that is the
same as (or less than) it was before the call to Clear, the "else"
branch is taken and the memory of buffer (at the address of nullptr)
is poisoned instead of the necessary allocation being performed. A
memset or memcpy on the returned pointer (nullptr) causes a
segmentation fault."
