Problem building libnetfilter_conntrack

[Chase Venters]

Hello,
    I'm trying to do some experimentation with libnetfilter_conntrack. I
noticed 
that r4363 does not build, from what I can tell, for a few reasons:

1. libnetfilter_conntrack is the new name, but the process of renaming
the header file does not seem to be complete
(include/libnetfilter_conntrack contains libnfnetlink_conntrack.h but
Makefile.in says:

> pkginclude_HEADERS = libnetfilter_conntrack.h

and libnetfilter_conntrack.c says:

> #include <libnetfilter_conntrack/libnetfilter_conntrack.h>

Perhaps libnetfilter_conntrack.h was not checked in?

2. Even when fixing the above, I seem to run into build issues:

I've tried other revisions, and I seem to always run into problems with
struct nfct_msg_handler. I'm going to try poking around a bit more
myself to see if I can find anything obviously wrong, but I suspect that
Subversion may be missing an updated libnetfilter_conntrack.h (from what
I can tell, 
libnfnetlink_conntrack.h hasn't changed since at least before r4295).

Any advice? Please CC me as I'm not yet a member of netfilter-devel.

Thanks,
Chase

I forgot to commit some changes to SVN. Please, update your working copy 
and try again.
