Move initial wait for network link into the state machine by adding

state S_PREBOOT and associated state_preboot() function.

This results in routing socket messages being processed even while
the link is being waited for. Thus the RTM_IFINFO message announcing
the link is ready can be reacted to immediately, rather than waiting
for the sleep(1)'ing process to wake up and look at the link state.

Some interfaces seem to lose the first packet sent when the RTM_IFINFO
message is reacted to so quickly, so temporarily leave in place an
explicit delay before sending the first packet.
