0.9.4.17:
	Fix a some policy violations that have crept in:
	* Canonicalize whitespace
	* Change genesis to output C code with canonical whitespace
	* Kill some gcc warnings
	* Change genesis to explicitly mark large integer literals
	  as unsigned

	Small test framework change:
	* Unexpected successes are reported, but do not cause a failure
	  return code for the whole test suite. There are some
	  non-deterministic tests that don't always fail.
