Get rid of a spurious dereference in DHCPRELEASE.

Change buffer for SIOCGIFCONF usage from 2048 to 32768. Because the
...
code to retry on SIOCGIFCONF not returning all interfaces is broken,
this unreasonably large buffer should handle the case of a machine
with lots of (usually virtual) interfaces. dhcpd 4 uses a different
method to get interface configuration, so this kludge should go away
on upgrade.
Fix based on understanding of the code, but has been compile-tested
only, to address failure report received from Michael Graff.

Follow NetBSD's interpretation of the interface to SIOCGIFCONF: the
...
next ifreq is sizeof(struct ifreq) after the current one unless the
sockaddr is bigger than the union in ifreq that holds it.
In the original 4.4BSD code, this interpretation results in the same
behavior as the "is the sockaddr bigger than struct sockaddr", because
sizeof(struct sockaddr) and sizeof(ifc->ifr_ifru) are the same.
Add comments pointing out problems in the 'need bigger buffer' code,
and copying excessive amounts of data.

before system header file inclusion magically causing what "read" is

of nowhere at all and using the trick referenced above).
