- The default repeat count for iostat(8) is 1 unless there
was a -w on the command line.
- A -x display doesn't include TTY or CPU stats by default
but they can be turned on with a -T or -C, respectively.

It's been broken for several years and with all the binutils/toolchain
changes in flight, it might make more sense to put efforts into dtrace and
hwpmc instead.

Modify the logic so there's only one exit point instead of two.
Only insert valid (non-NULL) values into the queue.
dispatch_free_command:
Ensure that item is not NULL before removing it from the queue and
dereferencing the pointer.
NULL out free'd pointers to catch any use-after-free bugs.

and updated comments in the usb_quirk.h header file.
The main purpose of this is to expose the quirks for ejecting 3G
modules. usb_modeswitch in Linux does a great job of collecting
information on these, and with the quirks module people can try out the
modeswitch config file entries on FreeBSD, hence the SCSI strings in the
man page.

extra MACHINE_ARCH symlink for certain platforms (such as pc98). The
support for creating these symlinks was added to sys/conf/kern.post.mk in
changeset 152964. The intention of that commit was to remove this code
from config(8), but config(8) was never updated.

- Sample CPU usage data from kern.cp_times, this makes for a far more
accurate and scheduler independent algorithm.
- Rip out the process list scraping that is no longer required.
- Don't update CPU usage sampling on every request, but every 15s
instead. This makes it impossible for an attacker to hide the CPU load
by triggering 4 samplings in short succession when the system is idle.
- After reaching the steady-state, the system will always report the
average CPU load of the last 60 sampled seconds.
- Untangling of call graph.

I'm unsure if some MIB standard states this must be the load average
for, eg. 300s, it looks like net-snmp isn't even bothering to implement
the CPU load reporting at all.
o We need an eval here to get the right expansion of the command
o bs=128k doesn't work in some cases, so eliminate it and cope with the
minor performance hit.
