Add some planar formats we can handle without distorting the meaning of
hi and lo.
Signed-off-by: Michael Niedermayer <michaelni@gmx.at>

It's often really helpful to know why a frame wasn't decimated (lo or
hi), and how much you exceeded the threshold by, if you're trying to
tweak the thresholds to get what you want.

mpdecimate already prints a line per input frame with -v debug, this
just makes it longer.

avfilter/vf_mpdecimate: pass the same AVClass context as use elsewhere to av_pixelutils_get_sad_fn()

Use a macro to abstract the endianness.

In Little Endian the vec_ld/vec_st operations work as
expected only for byte-vectors.

POWER 7 and POWER 8 support VSX and ldbrx.

POWER 8 supports additional extended VSX instructions introduced
with ISA 2.07.

Add POWER entries.

Should prevent trying to use altivec when it is disabled by the kernel.

The compiler is free to optimize such expressions in any sort of way.

This fixes the default build on iOS; eventually I should come up with
a better solution for that platform.

OSX does not know MSG_NOSIGNAL, and provides its own non-standard
