ipfilter: Move kernel bits to netpfil

Through fixes and improvements our ipfilter sources have diverged
enough to warrant move from contrib into sys/netpil. Now that I'm
planning on implementing MSS clamping as in iptables it makes more
sense to move ipfilter to netpfil.

This is the first of three commits the ipfilter move.

Also, always use -Wno-unknown-pragma to (hopefully temporarily) work
around #pragma ident in debug.h in the opensolaris code. Remove some
stale warning suppression that's no longer necessary.

Let modules use the kernel's opt_*.h files if built along with
the kernel by wrapping all targets for fake opt_*.h files in
.if defined(KERNBUILDDIR). Thus, such fake files won't be
created at all if modules are built with the kernel.

Some modules undergo cleanup like removing unused or unneeded
options or .h files, without which they wouldn't build this way
or the other.

new files and compile defines to build new ipfilter

Don't define PFIL_HOOKS. It's no longer required in RELENG_5 or HEAD.

NOINET6 -> NO_INET6

Recognise NOINET6 as an indication to not build IPv6 enabled source even
if FreeBSD header files, etc, support it.

Submitted by: Sergey Mokryshev <[email protected]>

IPv6 is on by default in GENERIC so enable IPv6 in IPFilter too by default.
