bios: Add bios stubs generated from assembly files
We substitute hardcoded fake bios handlers with ones generated
from assembly sources. This way we may extend them if needed.
In particular new int0x10 handler just write output into video
guest memory so the node machine may read the output anytime
it needs (though, to be fair, the kernel uses int0x10 only once
at bootup procedure if there was an attempt to boot directly
from disk/floppy, any other output is done via video port I/O
which is not implemented yet).
