Fixed calloc() and getopt_long()

Browse Source 
Added integer overflow test to calloc().

Tiny change in getopt_long() so that the value pointed to by the "longindex" parameter is always initialized to an invalid index position (that being -1), instead of 0. The value of 0 can break some shell commands, most notably GNU wget.
