mesa: Save and restore GL_RASTERIZER_DISCARD state during meta ops.
During meta-operations (such as _mesa_meta_GenerateMipmap()), we need
to be able to draw even if GL_RASTERIZER_DISCARD is enabled. This
patch causes _mesa_meta_begin() to save the state of
GL_RASTERIZER_DISCARD and disable it (so that drawing can be done
during the meta-op), and causes _mesa_meta_end() to restore it.
Fixes piglit test "EXT_transform_feedback/generatemipmap discard" on
i965 Gen6.
