Subject: moving more code around.

  * move rid allocation into IDMAP.  See comments in _api_samr_create_user()
  * add winbind delete user/group functions

I'm checking this in to sync up with everyone.  But I'm going to split
the add a separate winbindd_allocate_rid() function for systems
that have an 'add user script' but need idmap to give them a RID.
Life would be so much simplier without 'enable rid algorithm'.
The current RID allocation is horrible due to this one fact.
Tested idmap_tdb but not idmap_ldap yet.  Will do that tomorrow.

Nothing has changed in the way a samba domain is represented, stored,
or search in the directory so things should be ok with previous installations.

going to bed now.
