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?).

Now that we have the kthread mechanism, massively clean up the way
additional processors are spun up on multiprocessor Alpha systems.
Now, each processor gets its own idle thread (the primary processor

explicitly referencing proc0.

Also, make `curproc', `fpcurproc', and `curpcb' per-cpu values. This
required some data structure rearrangement; cpu info is now statically
allocated in the BSS, rather than via malloc(), and cpu_softc is gone.
(Modeled somewhat after NetBSD/sparc's multiprocessor info structures.)

Fix printf format problems on Alpha. (IRONIC?!)

More include shuffling.

If not MULTIPROCESSOR then identify the interrupt target cpu by hwrpb id (%d)
rather than attachment name, and hence avoid referencing `cpus'.

- Do not set TLCPUMASK on non-I/O nodes. That register exists only on
I/O nodes. Previous code erroneously set it on CPU nodes only.
- In both the single- and multi-processor case, route all interrupts from
I/O nodes to the primary CPU, for now.

Clarify comment about what nodes are being 'found' and noted for later
use by an error handler:

* There can be only one TurboLaser, and we'll overload it
* with a bitmap of found turbo laser nodes. Note that
* these are just the actual hard TL node IDS that we
* discover here, not the virtual IDs that get assigned
* to CPUs. During TLSB specific error handling we
* only need to know which actual TLSB slots have boards
* in them (irrespective of how many CPUs they have).

There can only be one TurboLaser node, and now we'll overload
into the integer tlsb_found a bit map of found nodes and export
it to the rest of the kernel. This is so that at machine check
time when we're doing some TLSB/KFTXX error handling we don't
have to attempt a badaddr to look at all TLSB nodes (which will
just be too sad to try...).
