- fixed ncacn_ip_tcp to use the generic async name resolution methods,
   so NBT names now work (as requested several times by abartlet!)

 - changed resolve_name() to take an event_context, so it doesn't cause
   the whole process to block

 - cleaned up the talloc_find_parent_bytype() calls to go via a cleaner
   event_context_find() call
