modeline: Handle version number overflow. #5450
Closes #5449
A file containing the string "vim" followed by a very large number in a modeline
location will trigger an overflow in getdigits() which is called by
chk_modeline() when trying to parse the version number.
Add getdigits_safe(), which does not assert overflows, but reports them to the
caller.
