get_bits: remove x86 inline asm in A32 bitstream reader
...
x86 does not use this variant so having inline asm there
is pointless.

Sanitise get_bits macros, part 1
...
Some of the macros in get_bits.h include a final semicolon,
some do not. This removes these or adds do {} while(0) around
the macros as appropriate and adds semicolons where needed in
calling code.

Remove "libmpeg2" bitstream reader
...
Using the libmpeg2 reader causes errors in a multitude of places,
including MPEG and H264 codecs. As the advantage of this reader
is questionable, removing it seems the sensible course of action,
especially considering the simplifications this allows elsewhere
with the bit cache size increasing from 17 to 25 bits as minimum.
