os: rework kernel architecture
Rework the code structure and architecture of the kernel by separating platform-dependent and platform-independent code more cleanly. As of this patchset, full feature parity has not been achieved. Nonetheless, a sufficient subset of functionality has been ported to the new architecture to demonstrate the feasibility of the new structure.
