Avoid integer overflow in hstore_to_json().
The length of the output buffer was calculated based on the size of the
argument hstore. On a sizeof(int) == 4 platform and a huge argument, it
could overflow, causing a too small buffer to be allocated.
Refactor the function to use a StringInfo instead of pre-allocating the
buffer. Makes it shorter and more readable, too.
