IPFilter 4.1.34 Imported

[Darren Reed <darrenr%netbsd.org@localhost>]

This afternoon I imported IPFilter 4.1.34 into NetBSD.
This import introduces the kernel configuration option "IPFILTER_COMPAT."
When present in a kernel config file, it will enable older versions of 
ipfilter
binaries to be used with a new kernel. It has been tested with x86 & sparc64
using a current kernel on 5.0 successfully.
