swscale: fix sign extensions in yuv planar conversion
...
Casting the left-most byte to unsigned avoids an undefined
result of the shift by 24 if bit 7 is set.
yuvPlanartouyvy_c and yuvPlanartoyuy2_c are affected.

The rationale is that you have a packed format in form
<greyscale sample> <alpha sample> <greyscale sample> <alpha sample>
and shortening greyscale to 'G' might make one thing about Greenscale instead.
An alias pixel format and color space name are provided for compatibility.

swscale: add two spatially stable dithering methods
...
Both of these dithering methods are from http://pippin.gimp.org/a_dither/ for
GIF they can be considered better than bayer (provides more gray-levels), and
spatial stability - often more than twice as good compression and less visual
flicker than error diffusion methods (the methods also avoids error-shadow
artifacts of diffusion dithers).
These methods are similar to blue/green noise type dither masks; but are
simple enough to generate their mask on the fly. They are still research work
in progress; though more expensive to generate masks (which can be used in a
LUT) like 'void and cluster' and similar methods will yield superior results

Aligning the tables reduces the amount of code generated on

so it can be encoded inside a single instruction instead of 2.
Ideally all should be declared aligned, but the DECLARE_ALIGNED
macros does not work with pointer tables, thus also reordered
the tables.

swscale: provide a default scaler if none is set
...
Lanczos for general case, sinc for upscaling, Gaussian for
downscaling. According to current literature these scalers
should be the best quality-wise algorithms for each case.

swscale: make bilinear scaling the default
...
Before this commit, sws_init_context() failed with an error if no scaler
was explicitly set.
Defaulting to something reasonable is better behavior.
