Support Daemon Stub

This patch supports that the daemon process can be the stub.
The daemon or service process has to call the rpc_port_register_proc_info()
to set the process name. When the proxy tries to connect to the stub,
the rpc-port library calls the aul_proc_get_name() if calling the
aul_app_get_appid_bypid() is failed.
