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?).

Establish interrupt handlers with proper softc per each zs device
rather than sharing them among all zs devices and searching softc
in handlers.

The latter method is derived from ancient sun3 zs driver which tried
to reduce overhead on autovectored interrupts, but nowadays such hack
might cause recursive global locks on modern SMP capable framework.

make sure we pass a valid consdev pointer to the console keyboard so kbd
knows it's console and passes the right flags to wskbd, now the wskbd will
not drop off the mux when leaving event mode.
Symptoms: now the keyboard should no longer be dead when leaving X and there
should be no more panics caused by it
I tested this on an SS5 and an SS20, may need some more attention and zs.c
sure could use some cleanup - there are a few differences to sparc64 that
really don't make much sense to me, like not passing console flags to zstty
which sparc64 does but sparc avoids, which caused this problem in the first
place.

various devices having different ideas about being console otherwise.

add two new functions for z8530tty: zs_chan_lock() and zs_chan_unlock(),

First steps for working wscons on sun-4 class machines - recognise the
console keyboard and mouse on them.

We are not there yet because currently both wsdisplay and zstty assume
that they are the console. On sun-4, zstty wins because it attaches
last and overwrites the console device that wscons had set previously.
