Extend the PCKBC_CANT_TRANSLATE feature, specific to Tadpole/RDI hardware,
to also support scan code set #3 in addition to the existing scan code set #2.

This makes the built-in keyboard on the Tadpole UltraBook IIe work.

Introduce a new knob to force the first USB keyboard as console input.

By setting "machdep.forceukbd=1" you can now use your USB keyboard in
ddb(4) even if your BIOS emulates a pckbd(4).

ok tom@, kettenis@, deraadt@

Follow the recent pckbc@isa changes and always establish all the necessary
interrupts at pckbc attach time, and get rid of the `intr_establish'
pckbc callback.

Tested on hppa (gsckbc) and sgi (pckbc@hpc); not tested on sparc64 (pckbc@ebus)
but this attachment was already behaving this way and its intr_establish
callback was an empty function.

Revert Active PS/2 support for now, until we find a solution suitable
for chipsets which stopped working.

ok mpi

Enable active PS/2 multiplexing if available.
Supported for i386 and amd64 except SMALL_KERNEL.

Based on Miod's former work on this subject.

ok mpi

simplify pckbc_xt_translation()
* call only for set translation on (once in /sys/dev/pckbd.c)
therefore we can delete unused code.
* change behavior (more standard) - return zero on success

ok miod@

disable the polling timeout when we suspend; discovered by some code
guenther is working on
ok miod

removed slot argument of function pckbc_cnattach
because it is always PCKBC_KBD_SLOT

ok krw@, miod@

Reset the keyboard controller on resume, and also alert the children
(pckbd and pms) to do their part
started by mlarkin, cleaned up by me
ok miod

Disable the heuristics for legacy free systems if pckbc flags are set to 1
in UKC; found the hard way by jakemsr@ on an old Tecra laptop.

Reenable the AUXWRITE dance to try and find the aux port in pckbc(4), based
on an attachment dependent flag; the Tadople SPARCLE needs it.
ok kettenis@ deraadt@

Add a new parameter to pckbc_cnattach(): flags to put in the pckbc bowels.
For now, only one such flag is defined, PCKBC_CANT_TRANSLATE. It hints
pckbc that the device does not behave correctly to the ``set translation''
commands.

Set this flag if we are running on a Tadpole Ultrabook machine, which needs it.
This makes the built-in keyboard work correctly on this laptop (with the
help of the software translation pckbd diff).

Remove __HAVE_NWSCONS and related remnants of pre-wscons days; no functional
change.
