4a160cbef4 avcodec/motion_est, mpegvideo: Make pointers to static storage const 
Modifying static storage must not happen because of multithreading
(except initialization of course), so add const to the pointed-to type
for pointers that point to static storage.

531fbce0b2 mpegvideo_enc: add intra_penalty option for p frames 
This option allows more control over the use of intra macroblocks in
predictive frames.

By using '-intra_penalty max', intra macroblocks are never used in
predictive frames.

It is useful for glitch artists to generate input material. This option
allows them to split and merge two video files while maintaining fluid
motion from the second video without having intra macroblocks restoring
chunks of the first video.

4b6b1082a7 lavc: Deprecate avctx.me_method 
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.

f6774f905f mpegvideo: operate with pointers to AVFrames instead of whole structs 
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.
