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.

9ffac3d00d lsws: duplicate ff_log2_tab
libswscale uses the table but wasn't duplicating it like the rest of the libs.
This should fix compilation failures on msvc/icl after lavu stopped exporting
internal functions and tables.

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.

Blackfin is a painful platform to work with, no test machines are available
and the range of multimedia applications is dubious. Thus it only represents
