Nouveau Adds ARB_copy_image, Intel Adds Another OpenGL 4.3 Extension Too

Following AMD adding ARB_copy_image support to the RadeonSI driver, Nouveau's NV50 and NVC0 Gallium3D drivers have now been wired up for this OpenGL extension.

Prolific community-based contributor Ilia Mirkin has implemented this OpenGL 4.3 extension for NVC0 (the NVIDIA Fermi and newer driver) as well as for NV50 as the driver for supporting the older NVIDIA graphics processors.

Meanwhile, Intel has added ARB_fragment_layer_viewport to their i965 Mesa driver as another OpenGL 4.3 extension. Nouveau NV50/NVC0, R600, RadeonSI, and LLVMpipe had already supported that extension.
