5ba90cd8ea pcm/PcmResampler: convert to abstract interface 
The PcmResampler interface is implemented by the two classes
FallbackPcmResampler and LibsampleratePcmResampler.  This prepares for
adding more resampler libraries.

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.

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."
