Implement support for keeping image provider alive
If you define QT_DIRECTFB_IMAGEPROVIDER_KEEPALIVE we make sure atleast
one IDirectFBImageProvider is alive at all times.
Apparently this is refcounted by DirectFB on atleast one implementation
and there's considerable overhead involved when releasing the
last/creating the first image provider.
