h264chroma: Change type of stride parameters to ptrdiff_t

This avoids SIMD-optimized functions having to sign-extend their
stride argument manually to be able to do pointer arithmetic.

h264: avoid undefined behavior in chroma motion compensation

Makes fate-h264 pass under valgrind --undef-value-errors=yes with
-cpuflags none. {avg,put}_h264_chroma_mc8_8 approximately 5% faster,
{avg,put}_h264_chroma_mc4_8 2% faster both on x86 and arm.
