Draw console on efi. Add vbe framebuffer for BIOS loader (vbe off, vbe on, vbe list, vbe set xxx). autoload font (/boot/fonts) based on resolution and font size. Add command loadfont (set font by file) and variable screen.font (set font by size). Pass loaded font to kernel. Export variables: screen.height screen.width screen.depth Add gfx primitives to draw the screen and put png image on the screen. Rework menu draw to iterate list of consoles to enamble device specific output. Probably something else I forgot... Relnotes: yes Differential Revision: https://reviews.freebsd.org/D27420
