Fix the return values of dhcp_packet_get and arp_packet_get.
...
This corrects a bug where stale dhcp packets would get reprocessed,
causing very bad behavior; an issue that was introduced in the
coroutine conversion.

Check link carrier via ifch and netlink instead of ioctl.
...
Thus, ioctl can once again be removed from the ndhc seccomp whitelist.

Indicate that client_state_t and client_config_t pointer args
...
cannot ever be null.
Could possibly improve code generation, and makes the intention clear.

Check for carrier before sendto() or write() on interface fd.
...
Linux will quietly proceed as if the data were sent even if the carrier
is down and nothing actually happened. There is still a tiny race
condition where the carrier could drop between the check and the actual
write, but we really can't do anything about that and it is a very
small race.

Just use raw sockets for listening to DHCP requests. A UDP SO_BROADCAST
...
socket was previously used only for receiving RENEWING packets, and it
added needless complexity and was somewhat fragile.
