commit 705599ff6aa29857e8ed1b3da11e6e8ba05e9aa9

    LP#1776510 JS libs handle transport errors
    
    Teach the websocket client code to look for the transport_error flag
    applied to the websocket wrapper message by the websocket gateway when a
    request for an unavilable service is made.
    
    When encountered, fire the transport or generic error handler callbacks,
    if available.  Avoid any attempts to further process the message.
