Make sure the new dir path exists before trying to rename files to avoid

2004-01-28  Jeffrey Stedfast  <fejj@ximian.com>

	* providers/local/camel-mbox-store.c (rename_folder): Make sure
	the new dir path exists before trying to rename files to avoid
	ENOENT errors. Also save errno when we encounter errors so that we
	can report the true error later rather than an error we may get
	while reverting changes. Also, it is OK if the ibex files don't
	exist, so check for that errno case.
