They are used by dnxhd and mpegvideo_enc exclusively, move them to codec
private options instead.

Having this macro in an header only facilitates the use of such header.
The code increase is minimal and files have one less dependency
on mpegvideo.h.

Mark it as static.

It is necessary to avoid circular header dependencies.

The main ff_alloc_picture() function is made more generic with all the
parameters necessary as arguments. This will allows to move most of the
related functions to a separate file later.

Right now wrappers are provided to try and minimize the number of
changes in the code.

Use more generic arguments and remove its static attribute since it will
be moved to a separate file.

This skips setting the memory to 0 but allows for reuse on different
contextes. Oracle did not report any unsual activity because of it.

The field is unused.

It is just a duplicate of an AVCodecContext member so use it instead.

They are just duplicates of AVCodecContext members so use those instead.

If it doesn't fit into 12 bits it triggers an assertion.

One step in untangling the mpegvideo code and fixing some problems in
the order that initialization is being done in h263dec and h261dec.
