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.
When stopping in the debugger after having called impossible, the windowing
state will have been modified since the assertion was hit. This made
examining state that caused the nhassert to fire no longer possible.
To avoid this issue, we now detect the debugger and stop in the debugger
prior to impossible.
When we were saving message history as part of a game save for insurance,
we were calling remember_topl() and thus inappropriately changing topline
state. This would cause us to mis-manage the topline in subsequent calls
to update the topline.
The code has been re-worked to fix the issue, reduce complexity and make
the code clearer.
When we save gamestate as part of making an insurance snapshot, we will
save message history which will clear toplines but leaving window state
in tack including the need for more.
When fuzzing, we would increment ttyDisplay->inmore but then prematurely
exit more() leaving ttyDisplay->inmore set.
Under various conditions, we can request to remember the topline when
the topline had not yet been acknowledged leaving toplin state in an
inappropriate state.
_snprintf and snprintf have one very important semantic difference.
_snprintf does NOT add terminating null character when the buffer limit
is reached while snprintf guarantees a terminating null character. It
was a mistake to make this naming change hiding the fact that the
semantics don't match what the developer might expect.
