introduced callback_job:

simple asynchronous method invocation
  use daemons thread pool for all threads
  proper cancellation and cleanups
  cancellation mechanism to dynamically unload multithreaded code
unified event_queue and scheduler => scheduler
unified job_queue and thread_pool => processor
removed job_type_t, not really needed
fixes here, there and everywhere
