mesa-8.0.x: Cherry-pick "dri/nouveau: don't use nested functions"

[Sedat Dilek]

Hi

I am playing again with llvm/clang v3.2 and patches I adapted from
LLVMLinux project.

I wanted to test my new toolchain before doing a rough testing of the
mainline Linux-kernel.

I decided to build the latest mesa-8.0.5 as I am on Ubuntu/precise
AMD64 here by making me and my build-deps happy (so NO mesa-9.x as it
requires a higher version of libdrm).

Unfortunately, I hit the same problem Johannes Obermayr already described.
Gratefully he points also in the BTS to the patch which is NOT in
"8.0" mesa GIT branch!
Thank you Johannes.

Can someone cherry-pick this one?

commit 4aa1ac5fe94b5696095229ee3568bf4fa7cfed95
"dri/nouveau: don't use nested functions"

Have fun!

P.S.: I have hit another build-error while writing this email, grrr!
