Andreas Rheinhardt 8fcc5d963e avfilter/vf_convolution: Fix build failures 
98e419cb added SIMD for the convolution filter for x64 systems. As
usual, it used a check of the form
if (ARCH_X86_64)
    ff_convolution_init_x86(s);
and thereby relied on the compiler eliminating this pseudo-runtime check
at compiletime for non x64 systems (for which ff_convolution_init_x86
isn't defined) to compile. But vf_convolution.c contains more than one
filter and if the convolution filter is disabled, but one of the other
filters (prewitt, sobel, roberts) is enabled, the build will fail on x64,
because ff_convolution_init_x86 isn't defined in this case.

Ruiling Song 98e419cbf5 avfilter/vf_convolution: add x86 SIMD for filter_3x3() 
Tested using a simple command (apply edge enhance):
./ffmpeg_g -i ~/Downloads/bbb_sunflower_1080p_30fps_normal.mp4 \
 -vf convolution="0 0 0 -1 1 0 0 0 0:0 0 0 -1 1 0 0 0 0:0 0 0 -1 1 0 0 0 0:0 0 0 -1 1 0 0 0 0:5:1:1:1:0:128:128:128" \
 -an -vframes 1000 -f null /dev/null

The fps increase from 151 to 270 on my local machine.

Derek Buitenhuis 21f9468402 avutil: Rename FF_CEIL_COMPAT to AV_CEIL_COMPAT 
Libav, for some reason, merged this as a public API function. This will
aid in future merges.

A define is left for backwards compat, just in case some person
used it, since it is in a public header.
