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.

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.
