522d65ba25 rgb2rgb: remove duplicate mmx/mmx2/3dnow/sse2 functions. 
Many functions have such a prefix, but do not actually use any
instructions or features from that set, thus giving the false
impression that swscale is highly optimized for a particular
system, whereas in reality it is not.

e2bad983b5 swscale: reformat x86/swscale_template.c. 
Interleave macros and code so that it's easier to find the
actual code that belongs to a function. Also reindent where
appropriate and remove dead code.

acb96bc268 swscale: remove if (c->dstFormat) branch from yuv2packed[12X](). 
This allows cutting up the function in much smaller and easier-

b6cac9b3bf swscale: remove if(full_chr_int) from yuv2packed1(). 
If that flag is set, swScale() already proxies the call to
yuv2rgbXinC_full(). Therefore, this flag is never set when
yuv2packed1() is called.

1bb0f0c925 swscale: remove if(bitexact) branch from functions. 
Instead, only set the function pointers if bitexact flag is
not set during initialization. Since a change in flags triggers
a re-init anyway, this doesn't situations where flag values
change during runtime.

566b5fbbb3 swscale: remove if(canMMX2BeUsed) conditional. 
Instead, set function pointers conditionally during init. This
patch also reveals a whole branch of dead assembly code that is
therefore also removed.

1dd4f4be5a swscale: remove AMD3DNOW "optimizations". 
The functions are identical to their MMX counterparts. Thus,
pretending that swscale is highly optimized for AMD3DNOW
extensions is a poorly executed practical joke at best.

c8f487deae swscale: fix YUV420P 9/10bit support. 
Fix handling of input if not in native endianness, and add support for
9/10-bit output. This allows us to force endianness of YUV420P 9/10bit
in the H264/10bit fate tests, which should fix them on big-endian
systems.

86330b4c92 swscale: partially move the arch specific code left 
PPC and x86 code is split off from swscale_template.c. Lots of code is
still duplicated and should be removed later.

Again uniformize the init system to be more similar to the dsputil one.

Unset h*scale_fast in the x86 init in order to make the output
consistent with the previous status. Thanks to Josh for spotting it.

c003832883 swscale: move away x86 specific code from rgb2rgb 
Keep only the plain C code in the main rgb2rgb.c and move the x86
specific optimizations to x86/rgb2rgb.c
Change the initialization pattern a little so some of it can be
factorized to behave more like dsputils.

db46be01ec Add unconditional return statement to yuva420_rgb32_MMX() / yuva420_bgr32_MMX(). 
When HAVE_7REGS was not defined these functions had an empty body
causing the following warnings during compilation.
