s4-ldb: added an optional operator_fn in the schema syntax
this function takes the operator being invoked, which will allow schema functions to provide more fine grained control over comparisons. The key bug this was introduced to fix is the incorrect handling of the LDB_OP_PRESENT test for deleted linked attributes. The backends are unaware of the deleted state of these links, so they cannot do a LDB_OP_PRESENT test on their own. Pair-Programmed-With: Andrew Bartlett <abartlet@samba.org>
