r4690: - add support for async rpc server replies
the backend should check for (dce_call->state_flags & DCESRV_CALL_STATE_FLAG_MAY_ASYNC) then it's allowed to reply async then the backend should mark that call as async with dce_call->state_flags |= DCESRV_CALL_STATE_FLAG_ASYNC; later it has to manualy set r->out.result and then send the reply by calling status = dcesrv_reply(p->dce_call); NOTE: that ncacn_np doesn't support async replies yet - implement an async version of echo_TestSleep - reenable the echo_TestSleep torture test (this need to be more strict when we have support for async ncacn_np) metze (This used to be commit f0a0dbeb25b034b1333078ca085999359f5f6209)
