*  Fix: Don't crash if the thread is interrupted while reading the public
    suffix database.
 *  Fix: Use relative resource path when loading the public suffix database.
    Loading the resource using a path relative to the class prevents conflicts
    when the OkHttp classes are relocated (shaded) by allowing multiple private
    copies of the database.
 *  Fix: Accept cookies for URLs that have an IPv6 address for a host.
