10.0.0 (testing), builds fine

ATM one patch is dropped, which makes ~30MB blow in $drivers,
because the shared gallium stuff isn't used by them.
ToDo: try to find if/when debian/ubuntu have an updated patch.

Note: in master this seems best included after LLVM-3.4 (scheduled Dec 23)
remove the double ./configure run
Merge commit 'refs/top-bases/vlada/mesa' into vlada/mesa

Conflicts (easy):
	pkgs/development/libraries/mesa/default.nix
update to 10.0.1 (stable, but TODOs)
init
3.3 -> 3.4: first shot
drop patch that didn't apply (because the default got tripled)
depend on v/llvm now
Merge commit 'refs/top-bases/vlada/mesa' into vlada/mesa
make R600 non-optional
Merge commit 'refs/top-bases/v/llvm' into v/llvm
Merge commit 'refs/top-bases/vlada/mesa' into vlada/mesa
