They are not just inverses of each other.
This should restore behavior to before the introduction of framerate

When decoding, this field holds the inverse of the framerate that can be
written in the headers for some codecs. Using a field called 'time_base'
for this is very misleading, as there are no timestamps associated with
it. Furthermore, this field is used for a very different purpose during
encoding.
Add a new field, called 'framerate', to replace the use of time_base for
decoding.

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.

Fixes an issue where the B-frame coding mode switches from interlaced
fields to interlaced frames, causing incorrect decisions in the motion
compensation code and resulting in visual artifacts.

Introduced by 28243b0d35b47bbf9abbd454fc444a6e0a9e7b71
Intensity compensation is always used once it was encountered, because
v->next_use_ic is never set back to zero.
Reset v->next_use_ic, when resetting v->next_luty/uv.

Fix https://trac.ffmpeg.org/ticket/3204
The problem was that intensity compensation was always used once it was
encountered. This is because v->next_use_ic was never set back to zero.
To fix this, when resetting v->next_luty/uv, also reset v->next_use_ic.
This improved (restored) performance by 85% when decoding

Use the intensity-compensated reference frame for subsequent
fields/B-frames.
Since we currently don't change the reference frame we have to
maintain lookup tables for intensity compensation in the following
dependent frames.
