Description

Declares ClfftInitializer class, which initializes and tears down the clFFT library resources in OpenCL builds, and does nothing in other builds, and a factory function for it.

clFFT itself is used in the OpenCL implementation of PME for 3D R2C/C2R transforms. It is know to work with NVidia OpenCL, AMD fglrx and AMDGPU-PRO drivers, and to not work with AMD Rocm dev preview as of May 2018 (#2515). TODO: find out compatibility with Intel once the rest of PME gets there (#2516), or by building clFFT own tests.
