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.

Justin Ruggles d9a542ace1 swscale: Set alpha to opaque for internal palettes. 
Fixes conversion of pal8 to rgb formats with alpha.

Updated references for 2 FATE tests which previously encoded fully
transparent images.

Martin Storsjö d192ac3e03 swscale: Disallow conversion to GBRP16 
This reverts parts of d6d5ef5534, that didn't work right. (The
tests that were added failed on big endian, and the output looked
garbled on little endian as well.)

This is due to the fact that the intermediate scaling values (from
e.g. hScale8To19_c or hScale16To19_c) are stored as int32_t and
thus requires a separate output function, while yuv2gbrp_full_X_c
only interprets it as int16_t.
