Raw kernel frontend

[tiehuis]

I would like to create a frontend for this which is a minimal operating system which boots directly into the game. This would be a minimal embedded example. The following are the steps that need to be done.

• [x] Create a minimal kernel (linker scripts, startup script, etc)
• [x] Create a buffered screen library (800x600 fixed)
• [x] Create a PS/2 keyboard driver for input state (plus scancode/keycode conversion)
• [x] Implement a simple random subsystem
• [x] Make modifications to the engine to allow freestanding compilation
• [x] Implement Serial library for debugging (hook in fsLog potentially).
• [ ] Integrate with the existing build system

The resulting image should run on i686 and x86_64 architectures ideally.

A kernel is now complete. Integration with the meson build is another story. Since this requires a cross-compiler and a lot of other tools it is a bit more complicated to integrate. It isn't a pressing priority either.
