Another kvm user can go away?

[Paul Goyette <paul%whooppee.com@localhost>]

I have managed to provide access to all of the kernel history data via 
sysctl, and I've come up with a modified version of vmstat(1) that can 
read the data from sysctl rather than having to use kvm.

Diffs for sys/sys/kernhist.h and sys/kern/kern_history.c can be found at 
www.netbsd.org/~pgoyette/my_vmstat/kernhist.diffs  In the same directory 
you can find a source file my_vmstat.c (and its associated Makefile).

Please review and comment (preferably constructively), and let me know 
what more needs to be done before it gets committed.
