Cedrus driver predates that, so it has implemented mechanism to check if all required controls are included in one request. Conform to specifications with removing that mechanism. Note that this mechanism with static required flag isn't very good anyway because need for control is usually signaled in other controls.

Progressive references have both, top and bottom reference flags set. Cedrus reference list expects only bottom reference flag and only when interlaced frames are decoded. However, due to a bug in Cedrus check, exclusivity is not tested and that flag is set also for progressive references. That causes "jumpy" background with many videos. Fix that by checking that only bottom reference flag is set in control and nothing else.
