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.

into a new directory. Specifically the handling of changes to lighting
lighting space (light in model vs. light in eye) have been revamped.
Moved several derived values used only by swrast into that directory.
Removed direct calls to swrast_flush() from vbrender.c -- pushed into
ctx->Driver.RenderFinish.
Optimized flat-shading case in swrast_setup.

- Remove support for choosing software fallbacks from core code
- Remove partial fallback code from vbrender.c -- drivers are now
expected to be able to find a triangle/quad function for every state,
even if they have to use _swsetup_Triangle or _swsetup_Quad.
- Marked derived variables in the GLcontext struct with a leading
underscore '_'.

based on the GL attribute groups.
Introduced constants describing the circumstances under which some
key derived values can change:
_SWRAST_NEW_RASTERMASK -- ctx->RasterMask
_SWRAST_NEW_TRIANGLE -- The software rasterizer's triangle
function
_DD_NEW_FEEDBACK -- the 'DD_FEEDBACK' bit in ctx->TriangleCaps
These are helpful in deciding whether you need to recalculate state if your
recalculation involves reference to a derived value.

Renamed struct gl_context to struct __GLcontextRec.
Include glcore.h, setup GL imports/exports.
Replaced gl_ prefix with _mesa_ prefix in context.[ch] functions.
GLcontext's Visual field is no longer a pointer.
