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.
