Cycles OpenCL: keep the opencl context and program around for quicker rendering

the second time, as for example Intel CPU startup time is 9 seconds.

* Adds an cache for contexts and programs for each platform and device pair,
  which also ensure now no two threads try to compile and write the binary cache
  file at the same time.
* Change clFinish to clFlush so we don't block until the result is done, instead
  it will block at the moment we copy back memory.
* Fix error in Cycles time_sleep implementation, does not affect any active code
  though.
* Adds some (disabled) debugging code in the task scheduler.
