Add an option COM_REGMAP to allow com(4) to use an array of register indices.
This allows us to convert aucom to just another com attachment, and cleanup
some code in the com_arbus.c.

Additionally, we use a common com_cleanup routine rather than having a
zillion copies of it in the attachment points.

This has been tested on a number architectures, and it has been shown to get
close to comparable performance when COM_REGMAP is defined, and comparable
when it is not defined.

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 initial support for Xorg server for wsfb(4):

- Fix WSDISPLAYIO_GTYPE ioctl.

- Support WSDISPLAYIO_LINEBYTES, _{GET,PUT}CMAP, and _SMODE ioctl.

As well as tiny improvements related to it:

- Use actual size of framebuffer for bus_space_mmap(9), as well as upper
bound for mmap(2).

- Use base address obtained from autoconf(9) layer for mmap(2), instead of
hard-coded one.

- Use rasops_cmap as default color map, instead of our own ANSI color map.

- Show monitor resolution and color depth instead of size as tty.

I've confirmed that mlterm-fb from pkgsrc/x11/mlterm also works fine.

Misc cleanup for clarity. No functional changes.

- Group function declarations, and reorder function bodies accordingly.
- Misc KNF.

Fix color map.

Almost all colors except *green* were wrong for the apparent reason ;).

Configure fb(4) appropriately also when it is not console.

Now, wsdisplay(4) can be used with serial console.

Avoid doubly bus_space_map(9) when pckbc(4) is already attached as console.

pckbcintr() must be running with IPL_TTY, not IPL_SERIAL. Otherwise,
tty(4) routines are unexpectedly interrupted, which results in
"locking against myself" errors for tty_lock.

Convert to intr_establish_xname().

Stop registering same function twice, i.e., for pckbd(4) and pms(4),
