unichrome 3d client driver in xc tree

[Thomas Hellstr�m]

Hi!
Following the previous mailing list discussion I've replaced the "via" 
3d client subdir in the xc tree with a corresponding "unichrome" one, 
which makes it possible to compile the unichrome 3d client driver in the 
xc tree. 

In order to make it compile, a small patch is needed to the Mesa source. 
I don't have cvs rights in that tree, so if somebody could care to check 
it in?
