Log Message:
-----------
Cycles / OSL:
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.
