Fuzzer improvements.

phase_of_moon and friday_13th determined using rn2() instead of local
time if fuzzing.  Don't reseed using init_random() if fuzzing.  Allow
set_random to be called outside of hacklib.  rn2_on_display_rng uses
rn2 if fuzzing so that we have a single source of random that we can
ensure is reproducible.  Implement rul() that returns a random unsigned
long.  Fix bug in fuzzer handling of ntposkey which would cause us to use
unitialized values for x and y.  Added command line arguments to allow
auto starting and stopping of fuzzer.  Add a logging facility for the
fuzzer to use to record activity.  Added some scripts used to automate
fuzzer testing on windows.
