4860625236 swscale: fix off-by-one in second coefficient in bilinear filters. 
If coefficient A is 12-bits xixed-point number "X", then the other
coefficient is (1 << 12) - X, not (1 << 12) - X - 1.

e7e19b15c7 build: Only clean the architecture subdirectory we build for. 
This allows simplifying the Makefiles; it is no longer necessary to register
arch subdirectory Makefiles, just putting them in place is enough.

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.

25c42234a9 swscale: make monowhite/black RGB-independent. 
Disadvantage is that it no longer allows modifying brightness through
adjustment of the RGB lookup table. Advantage is that now monowhite/black
no longer need to be identified as a RGB format.

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.

c0b87359b2 swscale: handle gray16 as a "planar" YUV format (Y-only, of course). 
This allows removing any gray16-specific code, which is essentially
identical to the per-plane code in yuv2plane*().

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.
