otherwise open_sockets() fails, which causes start_child() to fail silently.

Furthermore, if open_sockets() fails and child_state is CH_DIED, it will
not be possible to start it manually later; therefore, set child_state
to CH_STOPPED when open_sockets() fails.

Note: it wouldn't hurt if open_sockets() were a little more talkative.
