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.

Ensure that cabac init sets the bitstream pointer to an even value.
It is often faster to load from an aligned boundry

There is not much reason to generate such a small table at runtime.

works around bug in gccs inline asm register assignment
Fixes Ticket3177
gcc from 4.4 to 4.6 is affected at least, no non affected gccs known
clang seems not affected

The only use case of it was the selftest code, and there the slightly more
complex indexing that is needed after its removial doesnt matter.

The reason is this is easier for PIC code (in particular on darwin...).
Keep the old names as pointers (static in cabac_functions.h so gcc
knows these are just immediate offsets) so the c code can nicely stay the same
(alternatively could use offsets directly in the functions needing the
tables). This should produce the same code as before with non-pic and better
code (confirmed) with pic.
The assembly uses the new table but still won't work for PIC case.

not used outside the cabac test functions (which probably means it's
a bad test if it doesn't use the same tables as the real functions?)

This fixes standalone compilation of some decoders with --disable-optimizations.
cabac.h defines some inline functions that use symbols from cabac.c. Without
optimizations these inline functions are not eliminated and linking fails with
references to non-existing symbols.
Splitting the inline functions off into their own header and only #including
it in the places where the inline functions are used allows #including cabac.h
from anywhere without ill effects.
The functions are not used in any part of Libav, therefore testing them in the
cabac-test is unnecessary. Since this makes them unused, remove the functions.
Passing an explicit filename to this command is only necessary if the
documentation in the @file block refers to a file different from the
one the block resides in.

Otherwise doxygen complains about ambiguous filenames when files exist
under the same name in different subdirectories.
