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?).

branches: 1.13.30;
some bugs in chipsfb_putchar_aa():
- fix 64bit padding for scanlines
- clean out latch for every scanline
now fonts with odd widths look right

support anti-aliased fonts, glyphcache etc.

branches: 1.11.2;
fix a bunch of bugs & tpyos in chipsfb_mmap() so wsfb can actually work

branches: 1.10.6; 1.10.10;
__unuse the right function
( note to self - don't commit half asleep )

do as joerg requested and mark an unused function __unused

support WSDISPLAYIO_GET_FBINFO

avoid uninitialized use of defattr

branches: 1.6.2; 1.6.4;
- use R3G3B2 palette
- don't muck around in config registers that don't really concern us

first step to fix PR 46461 - don't jump through a NULL pointer when we're
not the console but the firmware set up the graphics hardware anyway

Replace the remaining KAUTH_GENERIC_ISSUSER authorization calls with
something meaningful. All relevant documentation has been updated or
written.
