The previous code dependent on the input buffer matching the
buffer that has been provided by yadifs get_buffer.
The API does in now way gurantee this though its often true.
This fixes some out of array reads.
The regression test checksums change due to "out of picture" values
being initialized differently.
There should be no visual difference in the filters output

The old code generates a termination packet with the same regions as the
start packet and page_state set to "only what changed"; the result is
that the termination packet is decoded as identical to the start packet.
The new code does as found in some DVB broadcasts: produce a packet with
no regions. This is done by expecting num_rects to be 0 rather than
using a flip-flop. ffmpeg.c is updated accordingly.
The main benefit of inlining this function is from constant
propagation for the 'field_based' argument. Instead of inlining
all calls, create two versions of the function for field_based
values of 0 and 1.

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 adds a hidden config variable for the mpegvideo.o dependency
and selects from the codecs which require it.

This macro is only used in two places, both in libavcodec, so this
is a more sensible place for it.
Two small tweaks to the macro are made:
- removing the trailing semicolon
- dropping unnecessary 'volatile' from the x86 asm

In particular, do not upcase first word, do not use final dot, use a verb
to specify what the option does, sort entries by name, apply random
vertical align.
Create a dedicated options subchapter, rather than a subchapter for each
option.
This is more consistent with the rest of the docs. Also apply misc minor
fixes for improving rendering.
The syntax of the 'glob_sequence' pattern type is explained in the image2
manual section, so there is no need to replicate it here.
Also discourage the use of such deprecated pattern type by not showing
examples employing it.
Replace the syntax explanation with an use example of the 'glob' pattern
type.
Allow to override the default 'glob_sequence' value, which is deprecated
in favor of the new 'glob' and 'sequence' options.
The new pattern types should be easier on the user since they are more
predictable than 'glob_sequence', and do not require awkward escaping.
This is limited to the chars that arent filtered by av_log() already
we might filter more aggressively if theres some case where this becomes
needed.
