  NOTE about async replies:
   if the backend wants to reply later:

   - it should set the WBSRV_CALL_FLAGS_REPLY_ASYNC flag, and may set a 
     talloc_destructor on the this structure or on the private_data (if it's a
     talloc child of this structure), so that wbsrv_terminate_connection
     called by another call clean up the whole connection correct.
   - When the backend is ready to reply it should call wbsrv_send_reply(call),
     wbsrv_send_reply implies talloc_free(call), so the backend should use 
     talloc_reference(call), if it needs it later. 
   - If wbsrv_send_reply doesn't return NT_STATUS_OK, the backend function 
     should call, wbsrv_terminate_connection(call->wbconn, nt_errstr(status));
     return;
