Subject: 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.
