loader: implement framebuffer console
Create common (linear framebuffer based) graphical local console with our own terminal emulator.
The UEFI does provide the framebuffer as default (at least 800x600x32 as minimum resolution), if possible, set the same for BIOS.
Add TEM as terminal emulator.
Use built in 8x16 font for fall back, load "best font" when available (see /boot/fonts) and pass it to the kernel as module.
add loadfont command for manual font loading.
add screen-font variable to make it possible to set font size by name (set screen-font without the value will list the alternatives).
Implement few gfx primitives to support drawing the display elements, including the png image for logo. We currently only do put logo at right lower corner of the screen.
Draw black on white by default (it does look better with illumos phoenix and is nice otherwise).
User can set ansi colors (0-7 or by names) via tem.fg_color and tem.bg_color
Implement common framebuffer set | get | list | on | off to manage the FB.
Introduce some nice bugs we can fix later.
