(effects other than the equalizer to be implemented)

fixed compilation of the intf

Note that this rework changes the current behavior: if VLC is in the background, the keys still control it, however if you start another key user (such as iTunes, QTP, etc.), it won't interfere and control the other app. That's why macosx-mediakeys-background was removed.

Thanks to Spotify for releasing their code.

fixes #4679

The current implementation is broken by design and only confuses the users. Use SPrefs to change hotkeys and advanced prefs only for advanced stuff such as jump length changing, etc.

This change should be backwards compatible as corresponding types were
added in ffmpeg in 2008.
