Improve overflow checks in string catenation.
* lib.c (cat_str, vscat): Use size_t type for the total, so
that the wrapping behavior we depend on for overflow detection
is well-defined. Also, there was an overflow check missing for
the total + 1 beign passed to chk_wmalloc. Instead of adding
that overflow check, let's just start the total at 1.
