atatat caea20e952 Add PTRTOUINT64() and UINT64TOPTR() macros to sys/sysctl.h for use by 
kern.proc, kern.proc2, kern.lwp, and kern.buf.

Define more MIB for kern.buf so that specific buffers can be selected
(only all/all is supported right now), and use a 32/64 bit agnostic
structure for communcating buffer information to userland.

Convert systat to the new kern.buf method.

Clean up the vm.buf* handling a little.  There's no actual need to
record the dynamically assigned OIDs, since sysctl_data can tell us
what we're looking at.

Oh, and fix a typo in a comment.

pk 498839ae5e Adapt to kernel buffer cache memort allocation changes. 
Since the buffer headers do no longer exist as an array in the kernel anymore,
use the new CTL_KERN.KERN_BUF mib to fetch them from kernel space.

Also look at a vnode's specinfo field to properly associate an opened
block device special file with a mounted filesystem.

christos 6a02b7be66 - avoid coredump by returning NULL when read fails and don't keep following 
the list.
- avoid zerodivide.
XXX: still does not work, but at least it does not core-dump.

jdolecek ecb9302c7f if kvm_nlist() fails, nlisterr() would be called before the screen 
curses context would be initialized; just use errx() instead in this case
this fixes coredump for cases like 'systat -N /netbsd.gz', reported by Walt
on port-i386

in nlisterr(), wait a while (5 seconds currently) before exiting, so that
it would be actually possible to actually see the error

mrg 3cf4c73d05 iostat(8) and systat(8) support for separate read/write disk statistics. 
"iostat -x" now shows these (ala linux/solaris), but this is only splitting
the read/write bytes/transactions, not adding any new metrics.  "systat
iostat" now has two new commands to switch between combined/separate mode
for both it's numbers & bar modes.

abs 3dbe098822 introduce puthumanint() which calls humanize_number(), and use to 
display disk transfer values (Suggested by Simon Burge). Also clip
%busy to 100 and display as an int which has the useful side effect
of stopping it overflowing into the next column (100.0).
