Clean up the checksumming stuff a bit:
have "ip_checksum()" compute the checksum of the IP header;
have "ip_checksum_state()" call "ip_checksum()" and then return
TRUE if the result is 0 and FALSE otherwise;
have "ip_checksum_shouldbe()" save the current value of the
checksum field in the header, set that field to 0, call
"ip_checksum()" to get the checksum, restore the value of the
checksum field in the header to the saved value, and then return
what "ip_checksum()" returned;
rather than having duplicated code to compute checksums.
