    audiolib: #if 0 out some dead code in XA and XMP support
    
    This doesn't look like it's intended to be dead code, but nothing sets Loop.Size anywhere.

    audiolib: less nasty looking MV_Voices[] allocation
    
    This removes the +2 bytes at the end of the allocation--I checked out the valgrind_errors.log referenced by the deleted comment and it looks like the issue fixed by 2e2e0e3af3378734c4f0b890c6b4d10253628416.
    
    This is the commit to revert if weird audio crashes start happening.
