This reverts commit da22ba7d since it
broke slice threading. Slice threading just duplicates MpegEncContext
so every value used during mpeg_decode_slice has to be in it.
A second patch will fix the illusion that Mpeg1Context is available
in mpeg_decode_slice.

It's MPEG-1/2 specific.

It's MPEG-1 specific.

It's used in lavf.

The way this value is used, it should be an unsigned type.
While the numerical value has no meaning, unsigned wraparound
is relied upon.

Using the old code, half of it was unused and the other half was too
small for e.g. >8bpp interlaced data, causing random buffer overruns.

Deprecate CODEC_FLAG_SVCD_SCAN_OFFSET

Deprecate CODEC_FLAG2_DROP_FRAME_TIMECODE

Deprecate CODEC_FLAG2_INTRA_VLC.

This allows using the same arm assembler offsets for both EABI
and the mach-o ABI.

FF_COMMON_FRAME holds the contents of the AVFrame structure and is also copied
to struct Picture.  Replace by an embedded AVFrame structure in struct Picture.

filter_mb_fast assumed that qscale_table was padded like many of the other tables.

It was long ago superseded by msmpeg4_version.

It has been deprecated for about five years, skip_idct/skip_frame should
be used instead.

This moves the fields needed by asm near the top, before any
structs or other members which complicate the offset calculation.
Modifying other structs will no longer require updating the offsets,
and the asm code is slightly simpler due to the smaller offsets.

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.
