Clock randomness gathering daemon

The Clock randomness gathering daemon gathers system randomness from fluctuations between different physical high-frequency clocks in a system. The randomness is tested with FIPS, and if this is successful, fed into the system entropy pool. It is especially useful for systems without real hardware random number generators.

      Release Notes: A interrupt changed flag was not declared as volatile, so if the code was compiled with optimizations it was likely not to work correctly. This bug has now been fixed.

        I wrote a patch which adds a makefile to clrngd. It also contains code so that clrngd will fork itself into the background to become a daemon.
        You can find the patch here:
