Using the malloc variant avoids pointless memcpy on size
increase and simplifies handling allocation failure.
Also change code to ensure that allocation, bswap and bitstream
reader all use the same size, even when the packet size is odd
for example.

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.

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

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.
