Add basic structure for fuzzing targets

Browse source 
General changes:

* Add -D/--deterministic command line option as
  convenience/alternative to -G/--load-seeds (i.e. no file needed, it just
  uses zero-initialized random seeds).  It also changes Broker data
  stores over to using deterministic timing rather than real time.

* Add option to make Reporter abort on runtime scripting errors
