gdal2tiles.py not support input raster from source other than file

[fechen123]

Expected behavior and actual behavior.

The following is not working now with gdal2tiles.py:

gdal2tiles.py --zoom=2-5 /vsizip/tgr.zip/tgrgtf1.tif tiles gdal2tiles.py --zoom=2-5 geor:user/pwd,,grtab,grobj,id=0 tiles

gdal2tiles.py: error: The provided input file /vsizip/tgr.zip/tgrgtf1.tif does not exist or is not a file

Not sure it is a bug or it is designed this way. But other python scripts such as gdal_polygonize.py support all the data sources.

Steps to reproduce the problem.

• create a zipfile with a tif file in it.
• run the above command.
