This file defines a single, huge function, MPV_motion(), which
although being declared inline is not actually inlined by the
compiler (for good reason). There is thus no sense in defining
this function in a header file, resulting in multiple copies of
it in the final library.

This feature is complex, of questionable utility, and slows down
normal decoding.

Interlaced images can have 32 references (16 per field), so limiting the
array size to 16 leads to invalid writes.

It is obscure, most likely unused and not bit-exact compared to
libavcodec due to a different IDCT transform algorithm.

Adds a new member to MpegEncContext to hold the number of used slice
contexts. Fixes segfaults with '-threads 17 -thread_type slice' and
fate-vsynth{1,2}-mpeg{2,4}thread{,_ilace} with --disable-pthreads.

This was intended as an optimisation for skipped blocks in MPEG2
P-frames and never used elsewhere. Removing this "optimisation"
speeds up MPEG2 decoding by 1-2% (ARM Cortex-A9).

This reverts commit da22ba7df461c13bf0b0eabc953303803a285d91 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.

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.

This allows using the same arm assembler offsets for both EABI

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.

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.
