'control' and 'extraintf' will be checked for occurences of 'macosx', which, if found, in turn will be removed. Other contents of these settings won't be touched. Same for all the other prefs.

Shared anonymous mapping did not make much sense.

This hopefully helps on scrollin bigger playlists as view is not always
back on top.

This fixes playback for wall-e bluray (and maybe others)

Should be now the same as it would be in fullscreen.

Avoid repeating the same implementation several times:
 incorrectly (switcher and mux didn't lock)
 redundantly (avcodec_register_all can be called several times)

Move libavXXX init at the top of a few functions, just in case.

Check uses of vlc_avcodec_(un)lock and factorize
