1) print the payload length in AH headers correctly (the field's
value is length of the payload, minus 2, divided by 2, so we
have to add 2 before multiplying by 2);
2) correctly handle, in an SIOCGIFCONF list, entries whose
address has an "sa_len" field less than the size of a "struct
sockaddr" (the length of the address in an entry is the
maximum of the real length and the size of a "struct
sockaddr").

libpcap, we may also want to return a flag indicating that we have to
map seconds/nanoseconds in the packet header to seconds/microseconds.

for AIX 5.x's non-standard libpcap, where "pcap_datalink()" doesn't
return DLT_ values, it returns RFC 1573 ifType values.
Put that wrapper, and the routine to get the interface list, in a
separate file, for packet-capture utility routines, so not everybody who
includes "util.h" needs to include <pcap.h>.
Fix up the Wiretap hack for dealing with said incompatibility to use the
correct ifType value for Token Ring.
