ac6eab1496 put_bits: fix invalid shift by 32 in flush_put_bits()
If flush_put_bits() is called when the 32-bit buffer is empty,
e.g. after writing a multiple of 32 bits, and invalid shift by
32 is performed.  Since flush_put_bits() is called infrequently,
this additional check should have negligible performance impact.

e6b22522c9 bswap: change ME to NE in macro names
Other parts of FFmpeg use NE (native endian) rather than ME (machine).
This makes it consistent.

ba87f0801d Remove explicit filename from Doxygen @file commands.
Passing an explicit filename to this command is only necessary if the
documentation in the @file block refers to a file different from the
one the block resides in.

43d7c6118d put_bits can only reliably write up to 31 bit bits, above it relies on
undefined shift behaviour.
Document this, fix the assert and add a put_bits32 to handle writing 32
bits and use that where necessary.
