PPC64: Add versions of functions in libswscale/input.c optimized for POWER8 VSX SIMD.
...
This patch addresses Trac ticket #5570 . The optimized functions are in file
libswscale/ppc/input_vsx.c. Each optimized function name is a concatenation of the
corresponding name in libswscale/input.c with suffix _vsx.

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.
