Remove possibility of mutiplicative integer overflow by not multiplying.
Instead of the widespread-but-overflow-prone
while (newlen < wanted) { newlen *= 2; }
idiom, just realloc() for the space requested by the caller and check
for additive overflow.
Also change type of 'newlen' variable from int to size_t to avoid
overflows there.
