     * <p>This method escapes the following characters as per RFC 4515:
     * <ul>
     * <li>\ (backslash) → \5c</li>
     * <li>* (asterisk) → \2a</li>
     * <li>( (left parenthesis) → \28</li>
     * <li>) (right parenthesis) → \29</li>
     * <li>\0 (null character) → \00</li>
     * </ul>
     *
     * <p><strong>Security Note:</strong> This method MUST be called on all user-supplied

   * instruct Java serialization to use it instead of the originally created object.
   *
   * <p>We have chosen this approach over at least two alternatives:
   *
   * <ul>
   *   <li>We could change the serialization of this class incompatibly. We have reserved the right
   *       to make such changes to our serialized forms, and we have made them before, usually

   *
   * <p>In addition to operating on {@code Map} instances, {@code MapJoiner} can operate on {@code
   * Multimap} entries in two distinct modes:
   *
   * <ul>
   *   <li>To output a separate entry for each key-value pair, pass {@code multimap.entries()} to a
   *       {@code MapJoiner} method that accepts entries as input, and receive output of the form

   * This method does so by hashing 64 bits of the IPv6 address into {@code 224.0.0.0/3} (64 bits
   * into 29 bits):
   *
   * <ul>
   *   <li>If the IPv6 address contains an embedded IPv4 address, the function hashes that.
   *   <li>Otherwise, it hashes the upper 64 bits of the IPv6 address.
   * </ul>
   *
   * <p>A "coerced" IPv4 address is equivalent to itself.
