Merge thorpej-cfargs2.

branches: 1.26.8;
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?).

convert the remaining dev/sbus drivers to CFATTACH_DECL_NEW, cfdata_t
and device_t, including the pci frontend and backend for en(4).

- use device_private(), proper types and variables for device_t/softc
- remove unnecessary casts against void pointer

XXX: many inconsistent use of aprint_*(9) and printf(9)

Remove struct sbusdev and related functions sbus_establish() and sbusreset().
They are derived from 4.4BSD/sparc and have been there since initial import
of NetBSD/sparc in 1993, but the struct sbusdev is almost unused for years,
nothing calls sbusreset(), and all (*sd->sd_reset)() functions look bogus.

Suggested by mrg@ and martin@, and tested on SS1+ and SS20.

struct device * -> device_t, no functional changes intended.

struct cfdata * -> cfdata_t, no functional changes intended.

ANSIfy another 1261 function definitions.
The only ones left in sys are beyond by sed script!
(or in sys/dist or sys/external)
Mostly they have function pointer parameters.

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.)

Merge the gehenna-devsw branch into the trunk.

This merge changes the device switch tables from static array to
dynamically generated by config(8).

- All device switches is defined as a constant structure in device drivers.

- The new grammer ``device-major'' is introduced to ``files''.

device-major <prefix> char <num> [block <num>] [<rules>]

- All device major numbers must be listed up in port dependent majors.<arch>
by using this grammer.

- Added the new naming convention.
The name of the device switch must be <prefix>_[bc]devsw for auto-generation
of device switch tables.

- The backward compatibility of loading block/character device
switch by LKM framework is broken. This is necessary to convert
from block/character device major to device name in runtime and vice versa.

- The restriction to assign device major by LKM is completely removed.
We don't need to reserve LKM entries for dynamic loading of device switch.

- In compile time, device major numbers list is packed into the kernel and
the LKM framework will refer it to assign device major number dynamically.

Adapt to sbusvar.h changes.

branches: 1.4.4;
Get rid of unnecessary BUS_SPACE_MAP_LINEAR.

Get rid of `bus_type_t' and use BUS_ADDR() (in sbus_bus_map()) to construct
a `bus_addr_t' to pass on to bus_space_map().

Drop `va' argument from sbus_bus_map(); it should not be used by MI Sbus
drivers.

frontend driver for the 16 port serial card by aurora technologies. this
doesn't quite work yet -- interrupt acknowledgement is hosed (and thus the
device keeps interrupting). uses the newly commited cd18xx backend.
