Merge thorpej-cfargs2.

Adapt to CFARGS().

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?).

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.

general overhaul, in no particular order:
- use MIPS_PHYS_TO_KSEG1()
- get rid of duplicated rasops_allocattr() and _mapchar() methods
- use rasops_init()
- support fonts that aren't 8x16
- use fastclear mode for rectangle fills
- don't mess with XMAP9's config register
- initialize all 32 XMAP9 mode registers, just in case
- make newport_fill_rectangle() use x, y, wi, he like everyone else
- use R3G3B2 palette in preparation for alpha font support

- pass the right address to bus_space_mmap() so this works on N32 kernels
- don't mess with XMAP9 when switching to graphics mode

Rebase to HEAD as of a few days ago.

Pull up following revision(s) (requested by macallan in ticket #977):
	sys/arch/sgimips/gio/newport.c: revision 1.15
remove leftover debug code

Pull up following revision(s) (requested by macallan in ticket #1009):
	sys/arch/sgimips/gio/newport.c: revision 1.14
No need to have two pre-defined screen types - just adapt to whatever
video mode we find. Also, redraw screen when X exits.
TODO: find out why characters are drawn upside down, for some bizarre
reason this happens right after exiting X but the last line is normal.

Pull up following revision(s) (requested by macallan in ticket #974):
	sys/arch/sgimips/gio/newport.c: revision 1.13
Don't bother drawing a cursor until wsdisplay attaches. This works
around the deadlock I've seen with the previous version.
While there do some KNF policing.

Pull up following revision(s) (requested by macallan in ticket #981):
	sys/arch/sgimips/gio/files.gio: revision 1.10
	sys/arch/sgimips/gio/newport.c: revision 1.12
Become a good vcons citizen.
Also, don't use the cursor sprite as text cursor - it's not worth the
pain and the sprite doesn't have an invert-background plane either so
the cursor wasn't transparent.
Instead blit the cursor using the appropriate ROPs. This way we get
rid of the cursor misplacement problem as well.
While there also use device_t.
TODO: arbitrary font sizes, cleanup, support for mapping all blitter
registers so we can use them from X.

Pull up following revision(s) (requested by macallan in ticket #963):
	sys/arch/sgimips/gio/newport.c: revision 1.11
A bunch of bugfixes:
- set blitter direction appropriately so scrolling downwards works now
- remove a bunch of false +1 so we only copy/erase what we really need
  to
- slightly change the logic for the cursor sprite offset so it works
  on this Indy ( I think what matters is VC2 revision 0 )
TODO: virtual consoles, fonts wider than 8 pixels

Kill caddr_t; there will be some MI fallout, but it will be fixed shortly.

IP12 (and perhaps other systems) appear to be buggy and incapable of
reliably supporting badaddr(). False negatives appear to occur
approximately 1.8 percent of the time, although neither false positives
nor consecutive false negatives occur. We take advantage of the latter
property and always use a wrapper that makes multiple checks.

My IP12 no longer sees occasional ghost devices and related panics during
boot.

Do not rely on the Product ID Word to be 0x04 since there is no such
thing for graphics options. Since we're removing this, ensure that we can
read the probe registers before proceeding.

sync with head - hopefully this will work

Add an extra cookie to the ioctl and mmap wsdisplay accessops that points
to the screen on which they are being called.  The driver cannot guess
this by itself but it is needed to implement, at least, the getwschar and
putwschar functions in the correct place.  There are no functional changes
yet.

Tested on i386 (vga, vga_raster, machfb, vesafb), macppc and sparc64.
Suggested and reviewed by macallan@.

More newport driver tweaks:

* detect and store vc2 revision.  This is (likely) the important factor in
  determining the proper cursor offset, so add a bit of logic that does the
  right thing on my revision 0 vc2.  This will have to be determined
  empirically, revision by revision.
* take a stab at detecting framebuffer depth.  SGI does it quite differently,
  but their algorithm doesn't work, so we'll do it along the same lines as
  linux.
* implement newport_mmap() for use by X.  The necessary xsrc commits have been
  made (with the notable exception of the config/cf changes, which probably
  shouldn't go in until 4.4.0 has been imported).

Remove unused dc_screens from the softc, the driver does not support multiple
screens.

Slight modifications to newport driver:

* Add resolution and depth variables to softc (for use in X driver, although
  depth detection is currently problematic),
* Store more information about various chip revisions,
* Implement ioctls to help the X driver detect device presence and geometry.

Correctly read the board revision.
