Cycles compile fix: only use std::isfinite when OSL is enabled.

* Removed last occurrence of get_pointcloud_attr_query.

* OSL can't overwrite input parameters, use a local variable instead.

Cycles / OSL:
* Updates for noise_turbulence, to match svm function.

Fixed a number of OSL syntax errors from the updated 1.2 API. Microfacet functions now all take an eta parameter, set to 1.0 if no IOR is given.

Fix for r50314:
* oren_nayar is not part of the default stdosl, added it back.

Fixed remaining syntax errors in OSL files. node_sepcomb_rgb.osl is split into 2 parts, since OSL only allows one shader per file.

Use function pointers instead of hard-coded english button names in color picker block.

This solves the problem with es/ru translations of color picker block reported by Gabriel Gazzán in Bf-translations-dev.

Cycles / OSL:
* Add oslutil.h, from osl 1.2.

OSL / Cycles:
* Update the stdosl header file, from official osl 1.2.

Cycles / OSL:
* Remove declaration of node_blend_weight_texture from cmake, does not exist, and match node_blend_weight name in nodes.cpp with the actual file.

Cycles / OSL:
* First batch of compile fixes for several shaders, mainly syntax errors.

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.

Cycles / OSL:
* Compile fix for the "direction_to_panorama" issue.
Added kernel_projection.h to kernel_triangle.h.

Enable shader model 3.0 shaders for mingw compilers

Fix #32463, Cycles crashing. The particle system sync_recalc part was checking object data, which can be NULL and doesn't actually say anything about particles, removed.

Cycles fix: don't skip particle device update when there are no particle systems. The device texture always contains at least one dummy particle in case particle info node is used for non-instance objects, this must be initialized in any case.

Cycles / OSLGlobals:
* Fixes for changes in the Open Shading Langauge API from version 0.6.0: https://github.com/imageworks/OpenShadingLanguage/commit/11ce51418b45e975ace4d919a4bdd8c2001ba300

* Removed the need for ShadingSystemImpl.

Cycles / OSL:
* OSL namespace fixes for osl_shader.cpp.
