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?).

malloc(9) -> kmem(9) (easy, straight-forward cases only, for now)

in many device attach paths, allocate memory with M_WAITOK instead of M_NOWAIT
and remove code to handle failures that can no longer happen.

src is too big these days to tolerate superfluous apostrophes. It's
"its", people!

avoid writing 1 byte beyond the end of the string promlib.c has given us.
instead of forcing a nul byte afterwards, KASSERT() that the final byte
already is a nul. if there are broken proms... well, we can fix them.

this, plus one more change, allows my SS20 to boot multiuser.

convert the remaining sparc drivers to CFATTACH_DECL_NEW/cfdata_t/device_t.
(cgsix_obio.c was only partially converted with the rest of the cgsix code
when it was changed some time ago.)

#include <sys/bus.h> instead of <machine/bus.h>.

- use device_t and cfdriver_t
- use device_private() and device_xname()
- use proper types or variables for device_t/softc

Merge the ppcoea-renovation branch to HEAD.

This branch was a major cleanup and rototill of many of the various OEA
cpu based PPC ports that focused on sharing as much code as possible
between the various ports to eliminate near-identical copies of files in
every tree. Additionally there is a new PIC system that unifies the
interface to interrupt code for all different OEA ppc arches. The work
for this branch was done by a variety of people, too long to list here.

TODO:
bebox still needs work to complete the transition to -renovation.
ofppc still needs a bunch of work, which I will be looking at.
ev64260 still needs to be renovated
amigappc was not attempted.

NOTES:
pmppc was removed as an arch, and moved to a evbppc target.

Merge some of the less invasive changes from the vmlocking branch:

- kthread, callout, devsw API changes
- select()/poll() improvements
- miscellaneous MT safety improvements

Kill caddr_t; there will be some MI fallout, but it will be fixed shortly.

G/c debugging printf (hi, macallan!).

PCI device list and interrupt mapping for JavaStation Espresso.
Interrupt line values from Linux sparc sources.

Remove declaration of a variable which is no longer used.

Make sure the file ends with a newline, so the port builds again.

add support for options BLINK

ANSIify. Use uint<N>_t. Drop unnecessary inlcudes.
Declare as static everything we don't need to export.
