vga: can run acme/rio/clock, no mouse yet.
Currently
- bug in poolalloc, so we're not using it yet
- bug in addclock0link, so not soft cursor timer
- vmap is no longer panic'ing if m->machno > 0, don't know why that was set.
But it properly sets and blanks the display.
You can now run stuff like acme and keyboard input works. No mouse.
Do this:
bind -a '#m' /dev/mouse
aux/realemu
aux/mouse ps2
aux/vga -m vesa -l 1024x768x8 && acme
(or other -l of your choice -- aux/vga -m vesa -p for a list)
start typing. Note typing works. No screen output on console.
