This is a preparatory step for the MSS2 decoder which needs to use
the WMV9 decoder to decode some kinds of frames.

Instead, use it on the first member, since by definition, if
any member is aligned, the whole struct must be, in order to
maintain that alignment.

Fixes compilation with some finicky compilers.

Idea for fix from Måns Rullgård.

They have most of their code in common.

This also makes sure the function pointers are stored via the same

This C99 feature is generally not used in the libav codebase,
since it breaks building with some fringe compilers (GCC 2.95,
MSVC).

The function is debug-only, so only compile it in debug mode.
Make it static as it has no uses outside of the file.
Change av_log() to av_dlog().

Defining tables in header files is ugly and prone to duplication.

The bitstream buffer must be padded, or the bitstream reader might
read over the end.

Put the zero length check in place of code that was never used
during decoding, as zero-length slices were generally refused
in decode_frame().
