    Remove a ridiculous realloc call from torgzip.c
    
    realloc()ing a thing in order to try to save memory on it just
    doesn't make sense with today's allocators.  Instead, let's use the
    fact that whenever we decompress something, either it isn't too big,
    or we chop it up, or we reallocate it.
