bios: stub calls interrupt number; simplified bios.ha main interface

Instead of having the bios.call stub calling a function, make it directly call an interrupt that is
changed dynamically by modifying the code at runtime.
Simplify the bios.ha interface and document it.

Next up: implementing a high level drive interface for the BIOS using BIOS interrupts
