Several updates to get server side sorting going:
- Added sort control to ads_do_paged_search. It allows a char * to be passed
as the sort key. If NULL, no sort is done.
- fixed a bug in the processing of controls (loop wasn't incremented properly)
- Added ads_do_search_all2, which funs a function that is passed in against
each entry. No ldapmessage structures are returned. Allows results to
be processed as the come in on each page.
I'd like ads_do_search_all2 to replace ads_do_search_all, but there's some
work to be done in winbindd_ads.c first.
Also, perhaps now we can do async ldap searches? Allow us to process a
page while the server retrieves the next one?
