Squash clang warnings.

Add support fot ia64. This means that ia64, for the first time ever,
has a working non-serial console!

I'm pretty sure this doesn't work on the SGI Altix 350, but that's
ok for now. Lot's of things don't work there...

Make sure to initialize early-boot keyboard drivers, as is apparently
required for the Sun UART-based keybaord driver to attach correctly. With
this change, vt(4) now works perfectly on sparc64 (at least on supported
hardware).

Checkpoint SPARC support. This seems to inexplicably crash fairly early on
somewhere outside of ofwfb.c. It is in no way clear why.

Make ofwfb static framebuffer much smaller by actually reading how you
are supposed to do this kind of thing.

Add a vt(4) framebuffer for Open Firmware linear framebuffer devices (i.e.
all graphics on PowerPC Apple systems). This will also work on some sparc64
graphics hardware with a small amount of modification.

Upgrade to Terminus 4.36.
