So far we only supported blitting the whole screen from the shadow
fb to the framebuffer. Add a function to blit areas.

The fb core now has builtin support for offscreen rendering, use
this and drop offscreen handling in the gui code.

Allocate the screen dynamically in fb_open. This opens the way to create
a fb_create_screen function which takes a struct fb_info * instead of a
filename. This is suitable for the framebuffer console which already has
a struct fb_info *.

get_pixel converts a 32bit trgb color into framebuffer format. This
is useful for other code aswell, so export it.
Other functions in the graphics utils code use the name get/set_pixel
aswell, but instead of converting data they get a pixel from the framebuffer
or set a pixel on the framebuffer. To separate from these rename the
function to gu_hex_to_pixel.

It's a render buffer, not a redering buffer.

This adds a common namespace to the graphic functions. We use
gu_ for graphic_utils.

Instead of passing hundreds of parameter, just pass the right structure.
struct screen represent the screen with a without double buffering.
struct surface represent the part of the screen we want to render.
