Move the transform and lighting code to two new directories

	math:  Provides basic matrix and vector functionality that
               might be useful to multiple software t&l
	       implementations, and is used by core mesa to
	       manage the Model, Project, etc matrices.

	tnl:   The real transform & lighting code from core mesa,
	       including everything from glVertex3f through vertex
	       buffer handling, transformation, clipping, lighting
	       and handoff to a driver for rasterization.

The interfaces of these can be further tightened up, but the basic
splitting up of state and code move is done.
