Description
The current KML Superoverlay driver cannot output transparent tiles if the output format is jpg.
This patch allows for this hybrid output where a tile is only created in png format if it contains nodata or transparent pixels.
The patch does not include any changes to the docs.

I've done a few changes, mostly suppressing a duplicated VSIMkdir() call that caused warnings to be emitted in kmlsuperoverlay_4 test, and fixing some compiler warnings.
prevents kmlsuperoverlay from generating thousands of empty tiles from sparse raster sources
