95b64804ab core: Move pa_mix() into new file mix.c 
idea is to allow optimized code path (similar to volume code)
and rework/specialize mixing cases to enable runtime performance improvements

no functionality changes in this patch

3d6092bb0f memblock: Add pa_memblock_acquire_chunk(). 
Besides making the code a bit cleaner, this also gets rid of
a few "cast increases required alignment of target type"
warnings.

2f7a586a23 sample-util: Remove redundant check from pa_volume_memchunk. 
Add also an assertion for the sample spec validity. The
existing code already does crash in case of an invalid
sample spec, but the error would not be as obvious: the
crash would happen due to a divide-by-zero operation in
pa_frame_aligned().

2ce7d38005 sample-util: Fix "Darth Vader" panning bug 
For muted channels, we forgot to increment a pointer, so if one
channel was muted but not the other, sound became distorted in a
Darth Vader like way. To test the difference, start two input
streams and pan one of them hard left (or right).

And hey, if you didn't think it sounded like Darth Vader, it's
your imagination that's broken, not mine! ;-)
