iptables: do not print trailing whitespaces
Due to the use of printf("foobar "), iptables emits spaces at the
end-of-line, which looks odd to some users because it causes the
terminal to wrap even if there is seemingly nothing to print.
It may also have other points of annoyance, such as mailers
interpreting a trailing space as an indicator that the paragraph
continues when format=flowed is also on.
And git highlights trailing spaces in red, so let's avoid :)
Preexisting inconsistencies in outputting spaces in the right
spot are also addressed right away.

extensions: libxt_CHECKSUM extension
This adds a `CHECKSUM' target, which can be used in the iptables mangle
table.
You can use this target to compute and fill in the checksum in
a packet that lacks a checksum. This is particularly useful,
if you need to work around old applications such as dhcp clients,
that do not work well with checksum offloads, but don't want to disable
checksum offload in your device.
The problem happens in the field with virtualized applications.
For reference, see Red Hat bz 605555, as well as
http://www.spinics.net/lists/kvm/msg37660.html
Typical expected use (helps old dhclient binary running in a VM):
iptables -A POSTROUTING -t mangle -p udp --dport bootpc \
-j CHECKSUM --checksum-fill
