1f80789bf7 sws: rename SwsContext.swscale to convert_unscaled
That function pointer is now used only for unscaled conversion.

f3c197b129 Include attributes.h directly
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.

e7f53d6ac9 lsws/ppc/yuv2rgb_altivec: Fix build in non-VSX environments
Add inline function for vec_xl if VSX is not supported. vec_xl intrinsic
is only available on POWER 7 or higher.

Fixes ticket #8750.

e6625ca41f swscale: Fix AltiVec/VSX build with recent GCC
The argument to vec_splat_u16 must be a literal. By making the
function always inline and marking the arguments const, gcc can
turn those into literals, and avoid build errors like:

swscale_vsx.c:165:53: error: argument 1 must be a 5-bit signed literal

Fixes #7861.

1bdb47b734 swscale: Replace illegal vector keyword usage in altivec code
While this technically compiles in current ffmpeg, this is only
because ffmpeg is compiled in strict ISO C mode, which disables
the builtin 'vector' keyword for AltiVec/VSX. Instead this gets
replaced with a macro inside altivec.h, which defines vector to
be actually __vector, which accepts random types.

Normally, the vector keyword should be used only with plain
scalar non-typedef types, such as unsigned int. But we have the
vec_(s|u)(8|16|32) macros, which can be used in a portable manner,
in util_altivec.h in libavutil.

This is also consistent with other AltiVec/VSX code elsewhere in
the tree.

Fixes #7861.

3a557c5d88 lsws/ppc/yuv2rgb_altivec: Replace vec_lvsl/vec_perm with vec_xl
gcc 6.x and 7.x generate wrong code for little endian machines
for the vec_lvsl/vec_perm instruction combos in some cases.
The bug was fixed in version 8.x
If these instructions are replaced with vec_xl, the problem goes
away for all versions of the compilers.

Fixes ticket #7124.

cd48318035 swscale: Add support for NV24 and NV42
The implementation is pretty straight-forward. Most of the existing
NV12 codepaths work regardless of subsampling and are re-used as is.
Where necessary I wrote the slightly different NV24 versions.

Finally, the one thing that confused me for a long time was the
asm specific x86 path that did an explicit exclusion check for NV12.
I replaced that with a semi-planar check and also updated the
equivalent PPC code, which Lauri kindly checked.

Fate passes, each format tested with an image to video conversion.

Only POWER8 includes 32-bit vector multiplies, so POWER7 is locked out
of the 16-bit function. This includes the vec_mulo/mule functions too,
not just vmuluwm.

This function wouldn't benefit from VSX instructions, so I put it
under altivec.

16.48 speedup ratio. On x86, SSE2 is ~7. Curiously, the Power C version
takes as many cycles as the x86 SSE2 version, yikes it's fast.

Note that this function uses VSX instructions, but is not marked so.
This is because several existing functions also make that mistake.
I'll submit a patch moving them once this is reviewed.

1df908f33f 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.

GCC tool had a bug of PPC intrinsic interpret, which has been fixed in GCC 4.9.1. This bug lead to
errors in two of our previous patches. We found this when we update our GCC tools to 4.9.1 and by
reading the related info on GCC website. We fix our previous error in two separate commits
