add stressVAOpolicy bench

[mp3butcher]

this is the cleaned code from openscenegraph/OpenSceneGraph#697
adding BIGCITY dataset could have been a bad idea

@mp3butcher Sorry for the slow turn around on this, I haven't been spending time tracking SceneGraphTestBed. Now catching up. Is this example and dataset still good to merge?

Previously I had a look at your BIGCITY.ive shared on a previous occasion when looking at VAO, is this the same model? In the one I have there is one building that is massively over scaled and rotated, is this a bug in the loader or the data?

I see that the model is over 50Mb, will this require git large file support to be used by myself or others?

Thanks.

It's the same model..I know it's awfull but it's a Blender CCO licenced city downloaded from https://www.blendswap.com/blends/view/69510 and then exported with osgexport or wavefront addon (can't remember)

Perhaps, I'm not familiar with git size limit. I imagine the problem may come from binary patch support. ...I don't know
I compressed it to 21 Mo with gz plugin if it helps

Thanks.
