Use this in vf_spp.c, where the get_pixels operation is done on
unaligned source addresses.
Hook up the x86 (mmx and sse) versions of get_pixels to this
function pointer, as those implementations seem to support unaligned
use.
This fixes fate-filter-spp on armv7.

pixblockdsp: Change type of stride parameters to ptrdiff_t

libavcodec/pixblockdsp.c(58) : warning C4028: formal parameter 1 different from declaration

This avoids SIMD-optimized functions having to sign-extend their
line size argument manually to be able to do pointer arithmetic.
Also adjust parameter names to be "stride" everywhere.

This patch adds MSA (MIPS-SIMD-Arch) optimizations for pixblock functions in new file pixblockdsp_msa.c
Adds new generic macros (needed for this patch) in libavutil/mips/generic_macros_msa.h
