Change Proposal Name OpenCL

Summary

This change will bring basic OpenCL support to Fedora to support the development of OpenCL enabled software and the development of OpenCL implementations itself.. This will include enabling Mesa's OpenCL state-tracker (in 9.3), packaging pocl - an CPU only OpenCL implementation - and the introduction of several other OpenCL related packages.

Detailed Description

The change is intended to give developers a starting point to be able to use OpenCL and to improve existing OpenCL implementations.

The change will include the following sub changes:

Add OpenCL implementations
- Enable OpenCL state-tracker in Mesa NEW
- Package pocl - CPU-only OpenCL implementation DONE
- Package beignet - Intel Ivy Bridge 1 only

Package implementation dependencies:
- Package libclc - needed by Mesa's state-tracker DONE
- Fix OpenCL path owenrship - Who owns /etc/OpenCL DONE
  - Review Request: opencl-filesystem - OpenCL filesystem layout - A package owning shared paths DONE

Package related packages
- Review Request: gocl - GLib/GObject based library for OpenCL - glib based OpenCL library DONE
- Review Request: clinfo - Enumerate OpenCL platforms and devices - A tool to query informations about the available OpenCL platforms DONE
- Review Request: erlang-cl - OpenCL binding for Erlang WIP
- Package ViennaCL - A math library whcih can utilize CPU (OpenMP) and GPU (OpenCL/CUDA) WIP
- Package pyopencl - A python library for accessing OpenCL BLOCKED BY rhbz #1002898

Update existing packages if needed
- gegl (to be investigated)
- ocl-icd (done)

Potential projects to be packaged:
- Package khronos icd - probably not
- Package radeontop - To monitor a Radeon GPU (which supports OpenCL)
- Package piglit - This will be a testuite for the OpenCL implementations

Other stuff:
- Add a new group to comps or a opencl-dev package?
- Add virtual provides to the opencl implementations - So a app requireing opencl just needs to require the virtual package (so any provider)
- Version opencl-headers

Benefit to Fedora

Developers will have an easier start to develop OpenCL based software on Fedora. Furthermore this shall be seen as a step o bring OpenCL based software to Linux in general.
