 1.12  07-Aug-2021  thorpej Merge thorpej-cfargs2.
 1.11  24-Apr-2021  thorpej branches: 1.11.8;
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?).
 1.10  20-Feb-2011  matt branches: 1.10.70;
Merge forward matt-nb5-mips64
Adapt to new interrupt/spl framework
 1.9  14-Mar-2009  dsl branches: 1.9.4; 1.9.6; 1.9.8;
Change about 4500 of the K&R function definitions to ANSI ones.
There are still about 1600 left, but they have ',' or /* ... */
in the actual variable definitions - which my awk script doesn't handle.
There are also many that need () -> (void).
(The script does handle misordered arguments.)
 1.8  14-Mar-2009  dsl Remove all the __P() from sys (excluding sys/dist)
Diff checked with grep and MK1 eyeball.
i386 and amd64 GENERIC and sys still build.
 1.7  11-Dec-2005  christos branches: 1.7.78; 1.7.86; 1.7.92; 1.7.96;
merge ktrace-lwp.
 1.6  13-Dec-2004  chs for drivers that support only one instance, use a global variable to ensure
that only one instance is configured rather than requiring that its
unit number be zero.
 1.5  15-Jul-2003  lukem __KERNEL_RCSID()
 1.4  02-Oct-2002  thorpej branches: 1.4.6;
Use CFATTACH_DECL().
 1.3  27-Sep-2002  thorpej Declare all cfattach structures const.
 1.2  30-Mar-2001  wdk branches: 1.2.2; 1.2.8;
Probe ISA bus devices
 1.1  12-Aug-2000  wdk branches: 1.1.2; 1.1.4;
Initial commit of port to MIPS Computer Systems RC3xxx systems.
Currently supports the RC3230
 1.1.4.1  09-Apr-2001  nathanw Catch up with -current.
 1.1.2.3  21-Apr-2001  bouyer Sync with HEAD
 1.1.2.2  20-Nov-2000  bouyer Update thorpej_scsipi to -current as of a month ago
A i386 GENERIC kernel compiles without the siop, ahc and bha drivers
(will be updated later). i386 IDE/ATAPI and ncr work, as well as
sparc/esp_sbus. alpha should work as well (untested yet).
siop, ahc and bha will be updated once I've updated the branch to current
-current, as well as machine-dependant code.
 1.1.2.1  12-Aug-2000  bouyer file mainbus.c was added on branch thorpej_scsipi on 2000-11-20 20:14:10 +0000
 1.2.8.2  18-Oct-2002  nathanw Catch up to -current.
 1.2.8.1  30-Mar-2001  nathanw file mainbus.c was added on branch nathanw_sa on 2002-10-18 02:38:53 +0000
 1.2.2.1  10-Oct-2002  jdolecek sync kqueue with -current; this includes merge of gehenna-devsw branch,
merge of i386 MP branch, and part of autoconf rototil work
 1.4.6.4  18-Dec-2004  skrll Sync with HEAD.
 1.4.6.3  21-Sep-2004  skrll Fix the sync with head I botched.
 1.4.6.2  18-Sep-2004  skrll Sync with HEAD.
 1.4.6.1  03-Aug-2004  skrll Sync with HEAD
 1.7.96.1  14-Jan-2010  matt device_t, CFATTACH_DECL_NEW, ansify, ...
 1.7.92.1  13-May-2009  jym Sync with HEAD.

Commit is split, to avoid a "too many arguments" protocol error.
 1.7.86.1  28-Apr-2009  skrll Sync with HEAD.
 1.7.78.1  04-May-2009  yamt sync with head.
 1.9.8.1  05-Mar-2011  bouyer Sync with HEAD
 1.9.6.1  06-Jun-2011  jruoho Sync with HEAD.
 1.9.4.1  05-Mar-2011  rmind sync with head
 1.10.70.1  21-Mar-2021  thorpej Give config_found() the same variadic arguments treatment as
config_search(). This commit only adds the CFARG_EOL sentinel
to the existing config_found() calls. Conversion of config_found_sm_loc()
and config_found_ia() call sites will be in subsequent commits.
 1.11.8.1  04-Aug-2021  thorpej Adapt to CFARGS().
