By default, VLCMediaLibraryKit will be compiled with and linked against
version 4 (pre-release) of VLCKit. To make this work, a patch against
libmedialibrary will be applied automatically to backport a
deinterlacing API change.

We need to be more precise when formulating simulator vs device compilation flags.

This fixes #28 and does not change the public API.

Providing no type to the media library is not supported and will result
in an empty list.

This is needed to implement vlc-ios#1141
