        * gfile.c:
        (g_file_copy):
        (g_file_move):
	Allow calls to implementation of copy and write
	even if the type of the file implementations is
	different. This can be used to implement native
	upload and download calls in a vfs.
	
        * glocalfile.c:
        (g_local_file_move):
	Protect against the case where move is called
	with one file not being local.
	
	Make sure we call the progress callback once
	in the native move operation so that the caller
	knows how many bytes were copied.
