From 41ce3dc0c3cbfdf06f0ffd3738c34ff8c22f450e Mon Sep 17 00:00:00 2001

Subject: s4:dsdb Add 'dsdb_flags' to dsdb_module_search() to enable often-used
 features

These flags, also on dsdb_module_search_dn() allow us to add commonly
set controls to this pre-packaged blocking search, without rebuilding
the whole function in each caller.
