Fixes for API changes in OSL RendererServices: * Added two new required get_matrix methods, from OSL RendererServices (otherwise the constructor fails). The two new matrix methods probably still need an implementation. * Removed deprecated "get_pointcloud_attr_query" and "pointcloud". There are two new routines for pointclouds, function headers for those are there. * Removed the (unused) PARTIO code parts from OSL. It was marked as not tested / not working, and due to the api changes here broken for sure. Code is still in svn history if needed.
