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.

+ * Two condition must be meet:
+ * min_lod =< max_lod == true
+ * max_lod =< last_level == true
+ *
+ *
+ * This is all fine and dandy if it where for the fact that max_lod

+ * max_lod = MIN2(last_level, max_lod);
+ *
+ * So we need to update the map state when we change samplers and
+ * we need to be change the sampler state when map state is changed.
+ * The first part is done by calling i915_update_texture in
+ * i915_update_samplers and the second part is done else where in
+ * code tracking the state changes.
