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.

swscale: clip unscaled output intermediates.
...
Fixes bug 240, as well as several integer overflows (visible as glitches)
in other scaling output routines, e.g. YUV422.

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.

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*().
