The end goal of this commit is to allow to boot on bare metal with no PS/2 device connected to the system. It turned out that the original code relied on the existence of the PS/2 keyboard, so VirtualConsole called it even though ACPI indicated the there's no i8042 controller on my real machine because I didn't plug any PS/2 device. The code is much more flexible, so adding HID support for other type of hardware (e.g. USB HID) could be much simpler. Briefly describing the change, we have a new singleton called HIDManagement, which is responsible to initialize the i8042 controller if exists, and to enumerate its devices. I also abstracted a bit things, so now every Human interface device is represented with the HIDDevice class. Then, there are 2 types of it - the MouseDevice and KeyboardDevice classes; both are responsible to handle the interface in the DevFS. PS2KeyboardDevice, PS2MouseDevice and VMWareMouseDevice classes are responsible for handling the hardware-specific interface they are assigned to. Therefore, they are inheriting from the IRQHandler class.
