Remove unnecessary (and unimplemented) WSKBD_*BELL ioctls in kbd drivers.

It looks the only ioctl(4) to be implemented for WSKBDIO_*BELL in
the backend keyboard driver is WSKBDIO_COMPLEXBELL.
All other BELL ioctls (WSKBDIO_BELL, WSKBDIO_SETBELL, WSKBDIO_GETBELL,
WSKBDIO_SETDEFAULTBELL, and WSKBDIO_GETDEFAULTBELL) are handled in the
MI wskbd driver (in wskbd_displayioctl() in src/sys/dev/wscons/wskbd.c).

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?).

Add missing semicolon

fix leak, found by Brainy.

Don't pull in the whole uvm(9) API to access only PAGE_SIZE and
some other constants. These are provided by sys/param.h now.

Remove deprecated powerhook_establish(9) since apmdev(4) which required
the old API was gone.

Add WSDISPLAYIO_LINEBYTES, which is required by Xorg wsfb server.

Clear RI_NO_AUTO in actual attach functions during autoconf(9)
for console devices that set the flag during consinit().

Set RI_NO_AUTO in ri->ri_flg if hpcfb_init() is invoked from cnattach.
Fixes silent hang on hpcsh and hpcmips.

XXX: all other rasops based console devices need to set this flag??

Register with pmf(9). Thus we register with both dopowerhooks(9) and
pmf(9), but they are mutually exclusive (apm(4) vs apmdev(4)).

Express pmf(9) hooks in terms of dopowerhooks(9) hook - the reverse
would be more natural, but pmf hook signature is hidden behind
PMF_FN_ARGS/PMF_FN_CALL, so just go the least intrusive way for now.

The only ones left in sys are beyond by sed script!

Mostly they have function pointer parameters.

Has this compiled recently?

Start detangling lock.h from intr.h. This is likely to cause short term
breakage, but the mess of dependencies has been regularly breaking the
build recently anyhow.

wsdisplay has been converted to device_t/softc separation so we can't cast
the wsdisplay device to the wsdisplay_softc anymore. Use device_private()
instead to get the softc.
