Include count for \0 character when using strncpy to implement strdup.
We have to include the \0 character in the length when copying a string with strncpy() for which length was found with strlen(). Otherwise the destination will not get null terminated - except that we explicitly zeroed it out earlier. This quiets down the compiler's warnings. Signed-off-by: Jes Sorensen <jsorensen@fb.com>
