[troff]: Fix Savannah #64229.
Throw diagnostic in event of a diversion's contents overflowing its
vertical position. We can't do anything sensible in this case, so make
it a fatal error. (It's also more likely that your host environment
will exhaust memory available to the `troff` process before encountering
this problem.)
* src/roff/troff/div.cpp: New constant symbol `DIVERSION_LENGTH_MAX`
defines the maximum permissible vertical size of a diversion in basic
units. Presently, it is `INT_MAX`.
(macro_diversion::distance_to_next_trap): When there is no diversion
trap, or it has already been passed, report the distance to
`DIVERSION_LENGTH_MAX` (rather than `INT_MAX`) divided by the vertical
resolution.
(macro_diversion::output): Check for overflow when incrementing
vertical position upon writing out a line, and emit fatal error
diagnostic if it occurs.
