Waiting for initialization request from upper layer

Because necessary information for joining the network such as self-node No. is
not set, a joining operation cannot be started.

The node waits until the parameters that permit joining the network are set by the
upper layer.

Waiting for joining token detection timeout Time for judging the current network
status. The time starts after an initialization request from the upper layer is
accepted. The monitoring time shall be 3 sec.

If even a token is received within this monitoring time, the network is judged as
an operating status. When the network is in the operating status, the self-node in
the network is put into the halfway joining initialization state.

When the network is not in the operating status, the self-node will join the
network at network initialization.
