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?).

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

branches: 1.18.26;
merge ktrace-lwp.

kill some more simple submatch() functions, use config_stdsubmatch()

replace the "locdesc_t" structure carrying the number of locators
explicitely by a plain integer array
the length in now known to all relevant parties, so this avoids
duplication of information, and we can allocate that thing in
drivers without hacks

branches: 1.15.2;
add more "const"

autoconf cleanup: turn xxxsubmatch() functions into the locator
passing variants

branches: 1.13.2;
Use aprint_normal() for cfprint routines.

Use CFATTACH_DECL().

Declare all cfattach structures const.

Introduce a new routine, config_match(), which invokes the
cfattach->ca_match function in behalf of the caller. Use it
rather than invoking cfattach->ca_match directly.

Const poison.

Add in a step to actually probe for MCPCIAs. This allows us to run on
4100s that only have two of four possible MCPCIAs.

branches: 1.6.2; 1.6.8;
- Add a comment explaining why we probe for MCPCIAs in the shuffled
MID order.
- Export the shuffled MID order; other files now need it.
- Don't derive the GID from the unit number of the mcbus. A user could
render his kernel non-bootable by using a different unit number in the
kernel config file. We (and the hardware) only support one MCBUS, so
simply use instance 0. Note that this will need to be adjusted if there
are even any multiple-MCBUS systems.

be more consistent about use of 'cputype'. e.g. it's in a header, don't
bother 'externing' it everywhere!

branches: 1.4.8;
attempt to catch some stuff for ev5 module info

Garbage-collect the old confargs stuff that was used in the Early Days.
It isn't really appropriate anymore. Replace it with a real mainbus
attach args structure.

redo misleading comment (thanks, soren)

Add in a define for a MCPCIA bridge register that would be suitable for
probing for with badaddr(9).
