was expecting it to be set, thus ignored it.
bin/29509 - because ipft_cookie wasn't reset to 0 before making the ioctl
call for each variable, only the first name to find was used, each successive
call just used the cookie.

8 bytes of data were dropped.
- If the packet is a fragment, return. There is no UDP header in this case.
- Don't set the FI_SHORT flag. Already tested in `frpr_short()'.
- Remove unneeded test `!fin->fin_off'.

IPv6 packets can contain headers (like options) before the TCP/UDP/ICMP6
header. pf finds the first TCP/UDP/ICMP6 header to filter by traversing
the header chain. In the case where headers are skipped, the protocol
checksum verification used the wrong length (included the skipped headers),
leading to incorrectly mismatching checksums. Such IPv6 packets with
headers were silently dropped. Reported by Bernhard Schmidt.

Initialise init_addr in pf_map_addr() in the PF_POOL_ROUNDROBIN,
prevents a possible endless loop in pf_get_sport() with 'static-port'

allowing rules to be set to match only ipv4/ipv6. And so ipnat must be updated
to actually set this field correctly but to keep things working for old
versions of ipnat (that will set this to 0), make the ioctl handler "update"
the 0 to a 4 to keep things working when people just upgrade kernels. This
forces NAT rule matching to be limited to ipv4 only, here forward, fixing
kern/28662

fix a bug that leads to a crash when binat rules of the form
'binat from ... to ... -> (if)' are used, where the interface
is dynamic. reported by kos(at)bastard(dot)net, analyzed by
Pyun YongHyeon.
