idmap_autorid: add idmap_autorid_iterate_domain_ranges[_read]()
Functions to perform an action on all domain range mappings for a given domain, specified by the domain sid. Inspired by a previous patch by Atul Kulkarni <atul.kulkarni@in.ibm.com>. Signed-off-by: Michael Adam <obnox@samba.org> Reviewed-by: Volker Lendecke <vl@samba.org>
