[Mesa-dev] i965: Don't use gl-context for fbo-blits

[Topi Pohjolainen]

This series introduces new blorp parameter type for blit programs
compiled from glsl-sources. For most parts the launch logic just
calls core i965 batch emission logic.
Vertex batches are handcrafted containing full vertex header
information. This is needed because the pipeline is programmed to
skip vertex shader, clip and viewport transformation in strips&fans
(SF) but to provide the vertices directly from vertex fetcher (VF)
to the windower (WM).

Topi Pohjolainen (14):
