CVS commit by faure: 

When rename() fails, for any reason other than file_exists/dir_exists/unsupported,
i.e. a real reason (access denied, does not exist etc.), just stop the job there
instead of attempting the copy+del method.
Side effects: fixes a kio_trash bug, and doesn't leave around the destination file
when trying to move(/rename) on the same partition (consistent with "mv")

Added regression tests for move() in multiple cases, including the "access denied" case.
