85e990e915 Don't try to use the non-standard alloca.h 
Variable-length arrays are C99 standard and are preferred over alloca. The only
compiler that needs alloca (MSVC) has it in malloc.h.

cd983245f1 Return a sample pointer from resamplers 
Both resampling and filtering now avoid copying samples when they no-op.

7b782f6afa Return a sample pointer from DoFilters 
This allows us to avoid copying samples when no filtering is needed. Doing the
same for resampling would require another temporary buffer in the device.

bd2721dc7a Use _mm_setr_ps instead of _mm_set_ps 
Apparently _mm_set_ps loads in reverse order compared to _mm_load_ps, so
_mm_setr_ps should give what we really want.

a11e1c0858 Ensure that LoopEnd > LoopStart 
For the benefit of Clang's static analysis, which doesn't know that a
static source will always have a valid buffer and a buffer must have a
non-0 loop range.

debd5346fb Add a couple asserts to ensure a proper buffer 
It should not be possible for a playing or paused source to not have a
valid buffer, but Clang's static analyzer doesn't know that. Hopefully
an assert will convince it.

f311f74001 Avoid freeing an in-use capture buffer 
When stopping, ALSA may capture into its own storage buffer. Do not free
the storage buffer if it first reads from it.
