ae4c9ddebc vf_psnr: sse2 optimizations for sum-squared-error. 
The internal line accumulator for 16bit can overflow, so I changed that
from int to uint64_t in the C code. The matching assembly looks a little
weird but output looks correct.

(avx2 should be trivial to add later.)

9879421f1a vf_psnr: always calculate MSE over full pixel range. 
This makes the output compatible with that of pretty much any other
tool that calculates PSNR.

a11c16a0b0 avfilter/vf_psnr: Prevent integer overflow. 
The 32-bit integer accumulator in MSE computation can overflow for 8-bit frame data.
(e.g., for 1080p white frame compared to a black frame can give sum of 255*255*1080*1920 > 2^32).
