It is an internal swscale symbol and thus should not be exported.

Based on a long debug session with Kostya.

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
a maintenance burden.

SPARC is no longer being used in any multimedia-related fields and the
VIS optimizations only represent a maintenance burden.

Also give consistent names to init functions.

Revert "swscale: update context offsets after removal of AlpMmxFilter."
(commit a95e3fa9)
and
Revert "swscale: Remove some write-only variables related to alpha handling."
(commit 9d03cb9f).

They broke alpha handling - it's the evil inline asm that still uses that
variable, so it's not truely write-only.

This makes it possible to dintinguish them from PAL8.

Fixes an invalid write in avpicture_layout().

It is obscure, most likely unused and not bit-exact compared to
libavcodec due to a different IDCT transform algorithm.

Fixes PAL8 to YUV conversion.

isGray() is left as a FIXME for later.
