LibGL+LibGPU+LibSoftGPU: Add virtual base class for devices

Browse source 
This adds a virtual base class for GPU devices located in LibGPU.
The OpenGL context now only talks to this device agnostic interface.

Currently the device interface is simply a copy of the existing SoftGPU
interface to get things going :^)
