Alex Kavanagh 86b3e38a54 Remove load-time mocking from unit tests 
This patchset removes the load-time mocking necessary due to load-time
function calls in 'constants'.  The constants are changed to run-time
functions and and the lazy feature of restart_on_change is used, and the
harden disable for unit testing is switched on when needed.
