e4a94d8b36 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.

71617884a2 aarch64: h264 chroma motion compensation NEON optimizations
Since RV40 and VC-1 use almost the same algorithm so optimizations for
those two decoders are easy to do and included.

c2625c26c5 mpegvideo: implement ff_put_h264_chroma_mc1 & ff_avg_h264_chroma_mc2
These are needed for lowres 3

This may fix Ticket2538

  sh4: Remove dubious aligned dsputil code

Conflicts:

If someone wants to maintain the sh4 code in ffmpeg, wants to
add more optimizations, or volunteers to maintain any of
what is removed here and can confirm that they are faster.
Then please contact us!

0c15a9aa7e sh4: Remove dubious aligned dsputil code
The code represents a considerable maintenance burden and it is not
clear that it gives a noticeable benefit to outweigh this after 10
years of improvements in compiler technology since its creation.
