Message:

implement multiboot v2 specification and use it in GRUB for UEFI

• improve multiboot v1 code, move defines to a common location
• rename VESA framebuffer stuff to generic "boot framebuffer"
• small collateral changes

Location:

kernel/genarch/include

Files:

• fb/bfb.h (moved) (moved from kernel/arch/ia32/include/drivers/vesa.h ) (2 diffs)
• multiboot/multiboot.h (modified) (4 diffs)
• multiboot/multiboot2.h (added)

kernel/genarch/include/fb/bfb.h
