Cycle CUDA: revert the f1aeb2ccf4 and 84f958754 busywait fixes for now.
...
It's unclear what kind of impact they have on performance at the moment, so I
rather play it safe and postpone this for 2.71.

Cycles GPU Performance Regression
From my testing this (what i should have done in the first place) reduces the regression a lot.
Lets hope it is enough or we have to go back to busy waiting.

Cycles: equi-angular sampling for homogeneous volumes
...
This adds an option in the Volume Sampling panel, which helps rendering lamps
inside or near volumes with less noise. It can also increase noise though and
needs improvements to support MIS and heterogeneous volumes, but since it's
useful in some cases already (especially world volumes) it's there now.
Based on the code in the old branch by Stuart, with modifications by Thomas
and Brecht.

surface is encountered.
