[FFmpeg-devel] [PATCH] avcodec/mathops: make zero_extend() an alias of av_mod_uintp2()

[James Almer]

They both do the same thing, but the latter has arch optimized implementations.

Alternatively, i could duplicate the optimizations from av_mod_uintp2()
for zero_extend() in libavcodec/{arch}/mathops.h since the c versions
differ between the two.
