cgram(6): Don't move over the last char and fix an assertion
The maximum value of cursor_x was the text length and thus also
*equaled* to extent_x, which broke the assertion in substitute()
and caused crashes.
In addition, the cursor could move just beyond the last character
on a line, which didn't make much sense.
So only allow the cursor move to the last char but not over it.
This also properly fix the above assertion issue.

cgram(6): Sync the rewritten version from NetBSD
Fixes:
* Do not consider the puzzle solved if all letters in the visible area
are substituted correctly. To be properly solved, the whole puzzle
must be solved, even those parts that are currently off-screen.
* Never place the cursor at the very right edge of the screen since that
does not work well with some terminals. The maximum valid x
coordinate is COLS - 1.
* Add horizontal scrolling. Make all coordinate handling symmetric in
regard to the horizontal and vertical axes. Previously, lines longer
than 80 characters could not be seen on the screen.
* Fix undefined behavior when pressing function keys, which was
resulting parts of the screen being cleaned.
Improvements:
* Remove the arbitrary limit of 128 characters per line. Even if
fortune(6) may never generate such long lines, the code is easy
enough to adapt to other sources.
* Properly clean up the allocated memory. Previously, only the string
arrays were freed but not the strings themselves.
* Allow navigation with page up/down keys.
* Consistently use char for characters, avoiding converting back and
forth between char, unsigned char and int.

grdc(6): Add '-t' option to show time in 12-hour format
Partially based on FreeBSD's implementation (revision 112749). But I
moved the AM/PM mark to the upper-left corner instead of the
bottom-right corner as in FreeBSD, because the mark in the bottom-right
corner would be flushed by scrolling.
In addition, improve the determination of AM/PM mark, including:
00:mm -> 12:mm AM
12:mm -> 12:mm PM

grdc(6): Fix 100% CPU usage and make timeout work again
grdc(6) was passing a timespec with tv_nsec = 1000000*1000, which is
invalid. So every nanosleep() call just returns with EINVAL error.
This causes grdc(6) to loop hard and uses 100% CPU. It also brreaks
the optional timeout argument; grdc(6) just exits immediately.
Fix the above issue by correctly setting the timespec argument.
This fix also makes the optional timeout argument work again.

games: Bring in monop(6) from NetBSD
monop is reminiscent of the Parker Brother's game Monopoly, and monitors
a game between 2 to 9 users. It is assumed that the rules of Monopoly
are known. The game follows the standard rules, with the exception that,
if a property goes up for auction and there are only two solvent players,
no auction is held and the property remains unowned.
