Switch OpenBSD/hp300 to wscons, still using on-board ROM fonts for now.
Main features:
- MI hil drivers, allowing live plug/unplug of devices, and the keyboard
does not need to be at id 1 anymore.
- SGC bus support on 4xx models. SGC frame buffers are supported too, but
not as console, though you can use them as a regular glass terminal if
you run a getty on ttyC0. Currently not compiled-in, awaiting for an sti(4)
fix to be commited.
- HP-UX compatibility interfaces are removed. grfinfo and hilinfo are removed.
X11 support is currently broken by these changes; X.org X11R6 support will
be available very soon.
Tested on hyperion and 4 different flavours of catseye/topcat/kathmandu; other,
older frame buffers (davinci, gatorbox and renaissance) could not been tested
but should work; please report any regression.
