Framebuffer console patches

[Sascha Hauer]

This is the current state of the framebuffer console patches that
went back and forth between Antony and me.

The framebuffer console has different compile and runtime selectable
fonts, color support and supports enough escape sequences to show the
console and the editor properly.

Thank you Antony for starting this and for your effort. Framebuffer console
support has been on my wishlist for quite some time now.
