This affected many FATE-tests: The number of failing tests went down
from 663 to 344. (Both numbers exclude tests that failed because of
unaligned accesses in code that is inside #if HAVE_FAST_UNALIGNED.)

Variables used in inline assembly need to be marked with attribute((used)).
Static constants already were, via the define of DECLARE_ASM_CONST.
But DECLARE_ALIGNED does not add this attribute, and some of the variables
defined with it are const only used in inline assembly, and therefore
appeared dead. This change adds a macro DECLARE_ASM_ALIGNED that marks
variables as used.

This change makes FFMPEG work with Clang's ThinLTO.

Make sure the scaling functions for the 9-15bits are used for
9-15bits bit depths correctly.

See merge commit '39d6d361'.

Removed previous swscale code under '#ifndef NEW_FILTER'
and removed unused fields of SwsContext

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.

Fixes compilation with Sun C 5.12.

Also give consistent names to init functions.

This simplifies the code and improves quality at the expense of a slight
slowdown of a rarely used function (no fate test uses it).

This separates code relying on inline from that relying on external
assembly and fixes instances where the coalesced check was incorrect.
