50ce296026 swscale: use dithering in DITHER_COPY only if not set -sws_dither none 
This patch uses dithering in DITHER_COPY macro only if
it was not used option '-sws_dither none'.
With option '-sws_dither none' it uses downshift.

For human eye dithering is OK, for video codecs not necessarily.
If user don't want to use dithering, we should respect that.

21f9468402 avutil: Rename FF_CEIL_COMPAT to AV_CEIL_COMPAT 
Libav, for some reason, merged this as a public API function. This will
aid in future merges.

A define is left for backwards compat, just in case some person
used it, since it is in a public header.

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.

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.
