This option is extremely codec specific and only a few codecs employ it.
Move it to codec private options instead: mpegenc family supports only 3
values, xavs and x264 use 5, and xvid has a different metric entirely.

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

Fixes valgrind mpeg4 failures

The most interesting parts are initialization in ff_MPV_common_init() and
uninitialization in ff_MPV_common_end().

ff_mpeg_unref_picture and ff_thread_release_buffer have additional NULL
checks for Picture.f, because these functions can be called on
uninitialized or partially initialized Pictures.

NULL pointer checks are added to ff_thread_release_buffer() stub function.

This also converts vc1, since that is mpegvideo-based.

This also converts vc1, since that is mpegvideo-based.

This misfeature is most likely completely useless and conflicts with
removing the mpegvideo-specific fields from AVFrame. In the improbable
case it is actually useful, it should be reimplemented in a better way.

This avoids SIMD-optimized functions having to sign-extend their
line size argument manually to be able to do pointer arithmetic.
