by a scale parameter.

NaCL has been disabled for awhile, so the code
will still build, but only with C versions.
This change removes the MEMACCESS() macros from
Neon and Neon64 source.

YUV 411 is very uncommon format. Remove support.
Update documentation to reflect that 411 is deprecated.
Simplify tests for YUV to only test with the new side by side YUV but keep old 3 plane test around with a macro for now.

ifdefs on a function level are not needed for neon functions, unless
they are conditionally enabled in row.h. No functions are conditionally
enabled at this time, so all ifdefs can be removed from row_neon.cc and

Remove inaccurate specializations for 1/4 and 3/4, since they round
incorrectly. Specialize for 100% and 50% are kept due to performance.
Make C and ARM code match SSSE3.
Make unittests expect zero difference.

Adds unittests that do 1 step conversion vs 2 steps to test end swapping versions match direct conversions.

yuv constants for bt.601 were previously ported to neon64, as well
as the code to respect other color spaces. But the jpeg and bt.709
colour conversion constants were still in armv7 form. This changes
the constants for aarch64 builds to be compatible with the code.
yuv constants are now passed as const *
Remove Yvu constants which were used for older version on nv21 but not new code.

Low level for NV21ToARGB written to accept yuv matrix used by
other YUV to ARGB functions.
Previously NV21 was implemented for Windows using NV12 with a different
matrix that swapped U and V. But the Arm version of the low level does
not allow the matrix U and V contributions to be swapped.
Using a new low level function that reads NV21 and uses the same
yuvconstants as other YUV conversion functions allows an Arm port of
this function.

On ARMv7 platform, q4 is used, but it isn't declared in clobber list.
It results that q4 isn't preserved automatically by compiler. So that the value of q4 is destroyed.
