 1.16  07-Aug-2021  thorpej Merge thorpej-cfargs2.
 1.15  07-May-2021  thorpej branches: 1.15.6;
A small bit of const poisoning.
 1.14  24-Apr-2021  thorpej branches: 1.14.2;
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?).
 1.13  04-Jun-2011  tsutsui branches: 1.13.70;
Split device_t/softc. pmax is tested on GXemul, compile test only for alpha.
 1.12  31-Mar-2006  thorpej branches: 1.12.86; 1.12.92; 1.12.96;
Use ANSI function decls, apply static.
 1.11  11-Dec-2005  christos branches: 1.11.4; 1.11.6; 1.11.8; 1.11.10; 1.11.12;
merge ktrace-lwp.
 1.10  26-Aug-2005  drochner kill some more simple submatch() functions, use config_stdsubmatch()
 1.9  25-Aug-2005  drochner 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
 1.8  27-Feb-2005  perry branches: 1.8.4;
nuke trailing whitespace
 1.7  26-Aug-2004  drochner branches: 1.7.4; 1.7.6;
turn the (unused) ioasic_submatch() function into something useful, use
the locator passing variant of config_found(), get rid of the macros
hiding cfdata accesses and include "locators.h" from the .c file only
 1.6  27-Sep-2003  tsutsui Use strlcpy() rather than strncpy() + `\0' termination.
 1.5  26-Sep-2003  tsutsui Remove casts and use %x in printf for tc_offset_t,
which is int32_t on both alpha and pmax.
 1.4  01-Jan-2003  thorpej branches: 1.4.2;
Use aprint_normal() in cfprint routines.
 1.3  13-Nov-2001  lukem add/cleanup RCSIDs
 1.2  16-Mar-1999  simonb branches: 1.2.20; 1.2.22;
Add NetBSD RCS id on first line.
 1.1  15-Mar-1999  jonathan MI ioasic softc and child-device structs, gc duplicate struct definitions.
Add MI ioasic functions, but dont enable on alpha until tested.
 1.2.22.1  10-Jan-2002  thorpej Sync kqueue branch with -current.
