get_bits: Move BITSTREAM_READER_LE definition before all relevant #includes
...
This avoids the danger that get_bits.h might get indirectly #included before
BITSTREAM_READER_LE is defined.
Also sort headers into canonical order where appropriate.

vorbis: Validate that the floor 1 X values contain no duplicates.
...
Duplicate values in this vector are explicitly banned by the Vorbis I spec
and cause divide-by-zero crashes later on.

Drop ALT_ prefix from BITSTREAM_READER_LE name.
...
The prefix is a historic remnant that probably meant "alternative".
Now that the A32 bitstream reader has been dropped it makes no sense anymore.

Replace int_fast integer types with their sized standard posix counterparts.

The _fast integer types provide no realworld benefits, but may introduce
portability issues and are just plain ugly.

vorbis: Replace sized int_fast integer types with plain int/unsigned.
...
int/unsigned is the natural memory access type for CPUs, using sized types
for temporary variables, counters and similar just increases code size and
can possibly cause a slowdown.

Remove explicit filename from Doxygen @file commands.

Passing an explicit filename to this command is only necessary if the

one the block resides in.

1.5x faster ff_vorbis_floor1_render_list, 5% faster vorbis decoding on Core2.
...
1.3x and 3% on G4.
Though I think only part of this speedup is due to my optimizations per se;
some of it is that I got a better roll on the GCC random code generator.
Trivial reorderings of this function have a disproportionate effect on speed.
