    upstream: two defensive changes from Tobias Stoeckmann via GHPR287
    
    enforce stricter invarient for sshbuf_set_parent() - never allow
    a buffer to have a previously-set parent changed.
    
    In sshbuf_reset(), if the reallocation fails, then zero the entire
    buffer and not the (potentially smaller) default initial alloc size.
