direct and indirect lighting differently. Rather than picking one light for each
point on the path, it now loops over all lights for direct lighting. For indirect
lighting it still picks a random light each time.
It gives control over the number of AA samples, and the number of Diffuse, Glossy,
Transmission, AO, Mesh Light, Background and Lamp samples for each AA sample.
This helps tuning render performance/noise and tends to give less noise for renders
dominated by direct lighting.
This sampling mode only works on the CPU, and still needs proper tile rendering
to show progress (will follow tommorrow or so), because each AA sample can be quite
slow now and so the delay between each update wil be too long.
Note that currently the reroute nodes are hardcoded to color values, which means they will not work for shader type connections (and possibly cause overhead for float and vector conversion). Looking into a solution.
The image file name function was updating the iuser->framenr using a supposed cfra parameter. However, the actual cfra is unknown when loading movies or sequences, so the iuser->framenr value itself was passed in its place, leading to incremental addition of the iuser frame offset. Removed the cfra parameter altogether from the image path function. This should instead be done separately if necessary, it's not an inherent part of constructing the image file name.
* Removed a workaround for the NodeType enum, uses consecutive values now.
I could not find issues with CUDA, when compiling with Toolkit 4.2 (all sm kernels) and regression files rendered fine on my GPU with sm_21.
The particle data is stored in a separate texture if any of the dupli objects uses particle info nodes in shaders. To map dupli objects onto particles the store an additional particle_index value, which is different from the simple dupli object index (only visible particles, also works for particle dupli groups mode).

* __OSL__ is now defined for CPU when building with OSL.
* First batch of compile fixes, remove some unneeded std namespace declarations and added missing includes.
* More fixes, replaced all remaining size variables with scale ones.
* Remove nonzero check in OSL textures, not needed anymore, was there to prevent division by zero for the size variable.
