replace ad hoc driver loading with a proper driver manager, new DDK, new PnP manager with device matching, asynchronous startup, resource ownership and removal, add shared PCI capability helpers, replace typed, rigid services with a proper service manager, implement proper system shutdown and restart, shutting down unloads drivers and shuts down services, add simple power button, remove heavyweight boot self-tests and SMP stress runs, add monotonic timestamps to kernel debug output, fruitless USB and PS/2 fixes, make test builds opt in.
