fc1eda543c 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.

e96c3b81ca avutil: rename AV_PIX_FMT_Y400A to AV_PIX_FMT_YA8 
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.

3e6016622e 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

* Use descriptions of libraries from the pkg-config file generation function
* Use "FFmpeg Project" as CompanyName (suggested by Alexander Strasser)
* Use "FFmpeg" for ProductName as MSDN says "name of the product with which the
  file is distributed" [1].
* Use FFmpeg's version (N-xxxxx-gxxxxxxx) for ProductVersion per MSDN [1].
* Only build the .rc files when --enable-small is not enabled.

4fab08c94f Optimize pure C unscaled yuv2rgb. 
Aligning the tables reduces the amount of code generated on
e.g. ARM as the offset constant then has few enough set bits
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

Conflicts:
	libswscale/utils.c

The default is left at bicubic until someone has compared the scalers
properly speed and quality wise.

6b3ff6f91a 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.
