Mans Rullgard 23ce6e7212 get_bits: remove x86 inline asm in A32 bitstream reader
x86 does not use this variant so having inline asm there
is pointless.

Mans Rullgard 990f213e57 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.
