Konstantin Seurer cb31b5a958 clc,libcl: Clean up CL includes
This patch does a couple of things to make CL integration with drivers
as seamless as possible:
- We pull in opencl-c.h and opencl-c-base.h to stop relying on system
  headers.
- Parts of libcl.h are moved to new headers that are incomplete CL-safe
  variants of libc headers.
- A couple of util headers are changed to remove now unnecessary
  __OPENCL_VERSION__ guards and make more headers CL safe.
- Drivers now include src/compiler/libcl and use headers like
  macros.h,u_math.h instead of libcl.h.
