b18f8cbf3d Revert two swscale commits.
Revert "swscale: update context offsets after removal of AlpMmxFilter."
(commit a95e3fa90b)
and
Revert "swscale: Remove some write-only variables related to alpha handling."
(commit 9d03cb9fc5).

They broke alpha handling - it's the evil inline asm that still uses that
variable, so it's not truely write-only.

Prevents crashes on 1-tap filter (unscaled). Also rename "bguf" argument

771bab7f57 swscale: fix crashes in yuv2yuvX on x86-32.
They were introduced in an earlier commit that introduced use of named
arguments. One cause was a typo, a second cause appears to be a bug in
x264asm that I work around by not using named arguments.

c928e91729 Hack around gcc 4.6 breaking asm using call.
gcc 4.6 no longer decrements esp to account for local variables.
Thus using call will end up overwriting some local variable.
So add an extra one it can safely clobber.
This is a huge hack because it's basically pure chance it works,
no idea how this is supposed to be done.

We would use the second half of the U plane buffer, rather than the
V plane buffer, to output the V plane pixels.

948ccdadf4 swscale: for >8bit scaling, read in native bit-depth.
For 9/10bit, it means we don't have to upscale to 16bit before
actual scaling or pixel format conversion, and thus a performance
gain.

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.

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.

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.

    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.

    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.

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.
