- Add macros to allow conflicting with all other devel projects
  to ensure we always install only one specific ffmpeg

- Conditionalize zimg to build on Leap 42.3

- Use autopatch

- Provide ffmpeg symbol without version on main package too

- Prefix all the devel packages and conflict between releases

- Fix setup call to enter to proper folder

- Conflict with other ffmpeg-devel packages, simply always pull
  one of them

- Move license markings to the libs itself
- Add condition to switch between full build and lib only one
- Add provides/obsoletes on the ffmpeg private headers

- Reintroduce conditional libxvid support since FFmpeg?s
  MPEG4-ASP encoder is not quite up to par
