Initial commit of new glucose code.

Browse source 
From a driver perspective, all that needs to be done
is call...

glucoseScreenInit(pScreen);

and glucose will take over for the acceleration. Something
like this should do...

if (!exa && !xaa)
	glucoseScreenInit(pScreen);
else if (!exa)
	driversXAAinit(...);
else
	driversEXAinit(...);

This code has been tested with the i915, i915tex and i810
and there's a few odd rendering quirks that need to be worked
out but they'll probably be in their respective drivers but
the framework is here now.

# A script that symlinks source files from xgl to glucose
#
# Author: Soren Sandmann (sandmann@redhat.com) (original)
# adapted for glucose by Alan Hourihane <alanh@tungstengraphics.com>
#
# Things we would like to do
#
# - Check that all the relevant files exist
# - AUTHORS, autogen.sh, configure.ac, ...
# - Check that we have actually linked everything
# - if a file doesn't need to be linked, then it needs
# to be listed as "not-linked"
# - Compute diffs between all the files (shouldn't be necessary)
# - possibly check that files are listet in Makefile.am's
# - Clean target directory of irrelevant files
#
