[core, ios, osx] cameraThatFitsCoordinateBounds

Added an API to get a camera that you can pass into -[MGLMapView setCamera:] that fits the given coordinate bounds, by analogy with -[MKMapView regionThatFits:] or -[MKMapView mapRectThatFits:edgePadding:].

Added mbgl::Map::getCameraOptions() for getting the current camera options more conveniently.
