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.

1bab6f852c swscale: make access to filter data conditional on filter type. 
Prevents crashes on 1-tap filter (unscaled). Also rename "bguf" argument
to "vbuf", seems that was a typo.

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.

8c433d8a03 swscale: rename "dstw" to "w" to prevent name collisions. 
"dstw" can collide with the word-version of the "dst" argument, causing
all kind of weird stuff down the pipe.

7e4d9d5d45 win64: add a XMM clobber test configure option. 
This will be useful to test more aggressively for failures to mark XMM
registers as clobbered in Win64 builds, and prevent regressions thereof.

e0c3e07387 sws: implement MMX/SSE2/SSSE3/SSE4 versions for horizontal scaling. 
Speed: from 3.9x to 9.6x speed improvement over C, and some small
(up to 15%) speed improvements over existing MMX code (particularly
for bigger filters).

3f04ab4fcd swscale: split hScale() function pointer into h[cy]Scale(). 
This allows using more specific implementations for chroma/luma, e.g.
we can make assumptions on filterSize being constant, thus avoiding
that test at runtime.

8a8d0ce208 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.

ef1ee362b3 swscale: implement >8bit scaling support.

formats with >8 bits per component (48bit RGB, 16bit grayscale,
9/10/16bit YUV).

13a099799e swscale: change prototypes of scaled YUV output functions. 
Remove unused variables "flags" and "dstFormat" in yuv2packed1,
merge source rows per plane for yuv2packed[12], and make every
source argument int16_t (some where invalidly set to uint16_t).
This prevents stack pollution and is part of the Great Evil Plan
to simplify swscale.

a27db4c349 swscale: fix function declaration keywords in x86/swscale_template.c. 
Remove inline keyword for functions that are only called through
their function pointers (and thus cannot be inlined); add av_cold
keyword to init function, and use av_always_inline instead of
inline for functions that must be inlined for performance reasons.

9bcbb250e2 swscale: fix types of assembly arguments. 
This prevents the following compiler warnings: "warning:
initialization from incompatible pointer type". Since the
variables are only ever used in inline assembly, their type
is actually irrelevant (so the part where it was wrong did
not invoke any buggy behaviour).
