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));
