The MSA optimization has been refined in commit 93218c2 and ce0a52e.
It is better than MMI version now.
Speed of decoding H264: 4.83x ==> 4.89x (tested on 3A4000).

Some files currently rely on libavutil/cpu.h to include it for them;
yet said file won't use include it any more after the currently
deprecated functions are removed, so include attributes.h directly.

Apply optimized functions according to cpuflags.
MSA is usually put after MMI as it's generally faster than MMI.

This allows masking CPU features with the -cpuflags avconv option
which is useful for testing different optimisations without rebuilding.

This reduces the number of false dependencies on header files and
speeds up compilation.

Consistently apply this rule: the guard name is obtained from the
filename by stripping the leading "lib", converting '/' and '.' to
'_' and uppercasing the resulting name. Guard names in the root
directory have to be prefixed by "FFMPEG_".
