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.

Convert doxygen to multiline and express bitfields more simply.

When decoding, this field holds the inverse of the framerate that can be
written in the headers for some codecs. Using a field called 'time_base'
for this is very misleading, as there are no timestamps associated with
it. Furthermore, this field is used for a very different purpose during
encoding.

Add a new field, called 'framerate', to replace the use of time_base for
decoding.

Also rename the enum values to be consistent with other DCT permutations.

It's got_frame, not data size

It will be useful in the upcoming transition to refcounted AVFrames.

These decoders use a special non-MPEG2 IDCT.  Call it directly
instead of going through dsputil.  There is never any reason
to use a regular IDCT with these decoders or to use the EA IDCT
with other codecs.

This also fixes the bizarre situation of eamad and eatqi decoding
incorrectly if eatgq is disabled.

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

It's more readable and less prone to breakage.

Just aligning it on the stack would have been possible but less reliable
