Add support for raster tile index with tiles of mixed SRS (TILESRS keyword)
Shapefile (vector layers or tileindex): PROJECTION AUTO in a shapefile layer now causes reading the .prj file
Remove useless orig_tilesrs field in layerObj struct
Correct test to resolve PROJECTION AUTO in msSHPLayerOpen() is '#if defined(USE_GDAL) || defined(USE_OGR)'
