mips: Carefully use device_set_private for cpuN.

But don't do it in cpu_attach_common because the callers aren't set
up right -- instead leave a comment about what's wrong, to be dealt
with later.

Merge thorpej-cfargs2.

Fix various typos in comments. Also add missing NetBSD RCS Id in some of these files.

branches: 1.19.8;
Merge thorpej-cfargs branch:

Simplify and make extensible the config_search() / config_found() /
config_attach() interfaces: rather than having different variants for
which arguments you want pass along, just have a single call that
takes a variadic list of tag-value arguments.

Adjust all call sites:
- Simplify wherever possible; don't pass along arguments that aren't
actually needed.
- Don't be explicit about what interface attribute is attaching if
the device only has one. (More simplification.)
- Add a config_probe() function to be used in indirect configuiration
situations, making is visibly easier to see when indirect config is
in play, and allowing for future change in semantics. (As of now,
this is just a wrapper around config_match(), but that is an
implementation detail.)

Remove unnecessary or redundant interface attributes where they're not
needed.

There are currently 5 "cfargs" defined:
- CFARG_SUBMATCH (submatch function for direct config)
- CFARG_SEARCH (search function for indirect config)
- CFARG_IATTR (interface attribte)
- CFARG_LOCATORS (locators array)
- CFARG_DEVHANDLE (devhandle_t - wraps OFW, ACPI, etc. handles)

...and a sentinel value CFARG_EOL.

Add some extra sanity checking to ensure that interface attributes
aren't ambiguous.

Use CFARG_DEVHANDLE in MI FDT, OFW, and ACPI code, and macppc and shark
ports to associate those device handles with device_t instance. This
will trickle trough to more places over time (need back-end for pre-OFW
Sun OBP; any others?).

Change cpus_booted back to a simple variable instead of a kcpuset.
octeon_cpu_spinup() was trying to set CPU status immediately on kernel
startup _well_ before the kcpuset was initialised.

Initialize PageMask and Wired registers on secondary processors.

Support "boot -1" to start an MP kernel in uniprocessor mode.
Sort sys/* includes while here.

KNF whitespace nits.

Remove 2 CPU limit in OCTEON interrupt controller driver.

Minor tweaks and cleanup.

Transition from __cpuset_t to kcpuset_t *. This brings the local pmap one
step closer to uvm/pmap, its eventual replacement. Tested on ERLITE MP kernel.

Reenable preemption before returning an error when trying to set the
watchdog to an invalid period.
