clang-3.4 and gcc-4.9 have it.

It is a processor feature, so it belongs there.

Based on e3fec3f0 for arm.

vector_fmul and vector_fmac_scalar are guaranteed that they can process in
batch of 16 elements, but their SSE versions only does 8 at a time.

Therefore, unroll them a bit.
299 to 261c for 256 elements in vector_fmac_scalar on Arrandale/Win64.

Makes fate-h264 pass under valgrind --undef-value-errors=yes with
-cpuflags none. {avg,put}_h264_chroma_mc8_8 approximately 5% faster,
{avg,put}_h264_chroma_mc4_8 2% faster both on x86 and arm.

The dependency is indirect through the h263/mpegvideo code.

The section name is the muxer, not the format.

Keep the sections alphabetically sorted.

Also add warning comment about threading implementations without matching
atomics implementation to the atomics fallback implementation.

Previously the default fragmentation method was only enabled
if writing an ISM file.

@parblock is only supported in very recent Doxygen versions.

Also drop support for building examples in library directories.
