Vittorio Giovara f84a1b597c swscale: support AV_PIX_FMT_YA16 as input 
Based on a long debug session with Kostya.

Vittorio Giovara 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.

Diego Biurrun 880e2aa236 Remove all Blackfin architecture optimizations 
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
a maintenance burden.
