libnetfilter_conntrack.h missing struct nf_conntrack definition

None of the libnetfilter_conntrack's "public" headers include the full
definition of struct nf_conntrack.

It's not a 'private' structure (__*), thought it uses private structures
within it...  This means I can't do things like memcpy() them, sizeof() them,
or even build an STL vector of them (yeah, I know, ew, yuck, c++).

Since nf_conntrack structs are passed around to the applications using nfct,
it seems reasonable to desire to do things with them.

Looks like this was sorta thought of. Apparently you can return
NFCT_CB_STOLEN which will cause it to not be freed. I can then keep pointers
to the object rather than the object itself...

Oh well - I already restructured my code to get around this. :)

So you can ignore the original email.
