Still high on the goods of act_ctinfo being accepted into kernel
net-next I thought it would be a good idea to offer the user space tc
side of things to control the wee beastie.

It's a pretty shameless copy/shunt/paste/hack of m_connmark and some of
the other tc action control programs and does fundamentally work (used
for testing of the kernel module)

There are no doubt some sharp edges that I'd like to knock the corners
off before a realistic attempt at submitting, so this is a general RFC
call to see what I've fundamentally done wrong and can clean up.

eg. I do update uapi/linux/pkt_cls.h to match the relevant bits of what
has gone upstream for act_ctinfo.  Should this be a separate commit?
