  MyRealloc(NULL, 0)  : returns NULL : but realloc(NULL, 0) is allowed to return NULL or non_NULL
MyRealloc() is similar to realloc() for the following cases:
  MyRealloc(non_NULL, 0)         : returns NULL and always calls MyFree(ptr)
  MyRealloc(NULL, non_ZERO)      : returns NULL, if allocation failed
  MyRealloc(non_NULL, non_ZERO)  : returns NULL, if reallocation failed
