Handle overflow when computing char display width (Bug#9496).

* character.c (char_width): Return EMACS_INT, not int.
(char_width, c_string_width): Check for overflow when
computing the width; this is possible now that individual
characters can have unbounded width.  Problem introduced
by merge from Emacs 23 on 2012-01-19.
