Remove use of object_guidebot_cannot_reach and instead track the
reachability of the object as a separate flag. This allows the game to
remember when an object was found, but unreachable. Previously, it
would store only that some unreachable object was found. Now, it stores
the index of the unreachable object. This extra information is not used
yet.

Utility xrange, inspired by the Python2 feature of the same name,
provides an object that returns successive values from [start, end). It
is useful when the end index is known in advance, and is particularly
helpful when that index is expensive to recompute.
Fix original bug that buddy was limited to 5 hints per program run, not
5 per boss as it probably should have been.
Due to savegame format limitations, this still is not right. Reloading
the game should restore Buddy_gave_hint_count to its value at save time,
but will not.
The movie code assumes that when the topmost window is closed, that
window must have been the movie window, and that the movie data can now
be freed. However, if the movie is paused, a new topmost window is
created to tell the user that the movie is paused. When that topmost
pause window is deleted, the movie code frees the movie data, even
though the movie is not done. Corruption ensues, ultimately leading to
a crash.

Add macro cf_assert ("control flow" assert) to hint to gcc that certain
conditions are impossible. Use it to avoid generating range checks for
situations that never happen. If the event did happen, the only
consequence would be truncated UI text, rather than a correctness
problem.
clang issues -Wformat-nonliteral when `vsnprintf` is passed the format
string from its caller. This is generally not useful. Fortunately, the
warning can be suppressed by annotating the function as format(printf).
Presumably, this is because clang now trusts that the caller would have
been warned for a bad format string.
