Move common option rom code to header file
We will have a linux boot option rom soon, so let's take all functionalitythat might be useful for both to a header file that both roms can include.

Convert multiboot to fw_cfg backed data storage
Right now we load the guest kernel to RAM, fire off the BIOS, hope itdoesn't clobber memory and run an option rom that jumps into the kernel.
That breaks with SeaBIOS, as that clears memory. So let's read all...
