- 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.

Lot's of clean-up in macros.h and mmath.h
|
|
Replace GLubyte with GLchan
Replace 255 with CHAN_MAX
|
|
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.

- FX bug fixes.
- Polygon mode and edgeflag work properly.
- Clipping works with edgeflag.
- Driver.ReducedPrimitiveChange() callback so drivers
that implement lines & points as triangles can turn culling off
before rendering groups of these primitives.
- Cleaned up feedback & select primitives.
