Add proper consinit(9) support for sti(4) at sgc framebuffer on hp300.

The cnattach functions for sti(4) and service switch check method
for 425e in com_frodo.c are taken from OpenBSD.
The strategy how to choose the console device in hp300_cninit() is
quite diverged from 4.4BSD and OpenBSD so it's tweaked by me.

Also put several changes in sti_sgc.c to reduce diffs from OpenBSD/hp300.

Tested on 425e and 362 (which still uses gendiofb(4), not sti(4)).

XXX: sti(4) requires uvm_km_alloc(9) and uvm_map_protect(9)
to copy and call ROM functions on the executable memory region, so
it can be called before UVM and related initializations are complete.
Probably it's time to consider about MI "deferred consinit()" API
in init_main.c (or elsewhere) for modern complicated VM system...

Switch NetBSD/hp300 to wscons with rasops. Simply ported from OpenBSD/hp300.

- Only A1416 Kathmandu (topcat) framebuffer on 425t is tested, but
all other variants (TigerShark, Hyperion, DaVinci, GatorBox, Renaissance)
should also work if they are working on OpenBSD/hp300.
- sti(4) and SGC bus support are not pulled because I don't have 425e
and I can't confirm that 362 and 382 actually have SGC bus.
(I'll commit a DIO based dumb driver for 362 and 382 framebuffers later)
- Xorg server with wsfb driver will also be integrated soon
once after keycode with NoSymbol problem is addressed.
(We have to re-think what code should be used on WSDISPLAY_COMPAT_RAWKBD)
- MI HIL keyboard and mouse drivers are working fine though
cngetc via hilkbd has some problem (still we can input commands).
- No old HP-UX like HIL ioctl compatibility (we removed COMPAT_HPUX anyway).
grfinfo(8) and hilinfo(8) will be removed shortly.

Demonstrated on NetBSD booth at Open Source Conference 2011 Kagawa.

Remove clause 3 and 4 from TNF licenses

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

Protect against multiple inclusion.

Replace resource map usage with extent maps.

Update the console attach interface now that bus_space is available.
Basically means that hardware drivers with console attachments are
now largely machine independent.

configure() prototype is in <sys/device.h>

Fix tipo inherited from old version of TNF copyright template.

Add prototypes as appropriate.

Fix logic errors in new console probe code that caused framebuffers
outside of "internal i/o" space to not even have a chance at console-hood.

Fix tested by Thorsten Frueauf <frueauf@ira.uka.de>, and offered with
my sincerest apologies that the bug ever existed in the first place.

Completely rework how the console is probed. Console probing no longer
requires pre-autoconfigured devices. Fix up some prototypes. Part of the
long journey towards new config. (GETTING THERE!)
