Rename pcm_convert_domain to pcm_domain.  Move it out so we can use it
without depending on the whole PcmConvert library.

1543e529f1 pcm/Dither: convert remaining methods to templates 
Use the SampleTraits template and let the compiler generate a special
case for S32 instead of reusing S24_P32.

The PcmResampler interface is implemented by the two classes
FallbackPcmResampler and LibsampleratePcmResampler.  This prepares for

3a666702af pcm/PcmConvert: add AudioFormat parameters 
Don't use src_format.  In the middle of Convert(), the current
AudioFormat has already been modified, it's now something in between
src_format and dest_format.  This simplifies keeping track of what
remains to be done.

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
bit overflows.  This commit makes 24 bit a special case with explicit
clipping.
