Version 4 of VBO and GLSL code from xreal, w/ changes

I took your advice and took a look at ET-Xreal's GIT repository, but I'm sort
of wary about directly integrating changes, as ET's source code release was
covered by GPLv3, whereas Quake 3's was covered by GPLv2.

Still, I wrote up my own version of the glMultiDrawElements part, and added a
simple optimization (r_mergeMultidraws) that netted me 2fps on tvy-bench.  I
also copied out ET-Xreal's version of R_CullLocalBox(), as the file header for
tr_main.c stated GPLv2, so I'm thinking that's still covered by that.

I somehow broke merging cluster surfaces in this version of the patch though. 
I'm looking into it.
