emaste 4a841fdff4 amd64: Parse the EFI memory map if present
With this change (and loader.efi from the projects/uefi branch) we can now
boot under qemu using the OVMF UEFI firmware image with the limitation
that a serial console is required.

(This is largely r246337 from the projects/uefi branch.)
