Merge branch 'gallium-0.1' into gallium-0.2
A first attempt at moving gallium onto a branch directly off master... It will be interesting to see how much work this takes to get running. Have resolved the conflicts semi-arbitarily, not compiled or tested.

+ * Constant State Object (CSO) cache.
+ *
+ * The basic idea is that the states are created via the
+ * create_state/bind_state/delete_state semantics. The driver is expected to
+ * perform as much of the Gallium state translation to whatever its internal
+ * representation is during the create call. Gallium then has a caching
+ * mechanism where it stores the created states. When the pipeline needs an
+ * actual state change, a bind call is issued. In the bind call the driver
+ * gets its already translated representation.
+ *
+ * Those semantics mean that the driver doesn't do the repeated translations
+ * of states on every frame, but only once, when a new state is actually
+ * created.
+ *
+ * Even on hardware that doesn't do any kind of state cache, it makes the
+ * driver look a lot neater, plus it avoids all the redundant state
+ * translations on every frame.
+ *
+ * Currently our constant state objects are:
+ * - alpha test
+ * - blend
+ * - depth stencil
+ * - fragment shader
+ * - rasterizer (old setup)
+ * - sampler
+ * - vertex shader
+ *
+ * Things that are not constant state objects include:
+ * - blend_color
+ * - clip_state
+ * - clear_color_state
+ * - constant_buffer
+ * - feedback_state
+ * - framebuffer_state
+ * - polygon_stipple
+ * - scissor_state
+ * - texture_state
+ * - viewport_state
