Implementation of dri2proto support - xf86-video-nouveau

Registered by Ilias Biris on 2011-11-14

Development of dri2proto, updating libdri2 to support dri2video and dri2video test app, updating mesa and implement the core functionality in xserver against xf86-video-nouveau.

For first stage the support for xf86-video-nouveau driver will be implemented as reference, since:
(a) it is hw more widely available to xorg developers and xorg packagers for ubuntu, and
(b) it allows testing that without breaking compatibility with binary nvidia driver.

Since 12.04 is a LTS, there was concern about introducing a change that could break compatibility. Rather than having to package special linaro build of whole x11 stack, this approach seems reasonably safe in order to make progress and allow comfortable and safe review from the x86 side.
