The current support in mesa for ARB_multi_draw_indirect is pretty shameful... it just does N separate draws. Instead make it possible for drivers to handle this in a more efficient manner. Also create the backend interfaces necessary to support ARB_indirect_parameters, although the (trivial) frontend bits are not part of this series.
Of course right now st/mesa will still break up the multidraw into N draws since no backends actually support this. And there are no piglits (other than one in images) which actually make use of glMultiDraw*Indirect... oh well. The nvc0 support is going to be a tad tricky for this since I can't feed an arbitrarily-sized buffer into the command stream (something like 2K max items per command). So I need to split it up. And I need to beef up the macro we use for it. That's all a task for next year though.
