> Original change's description:
> > Add thread guards to JsepTransport
> >
> > This ensures that JsepTransport's methods are either only accessed on the thread
> > that creates it, or using methods that are marked for off-thread use
> > (using a lock to prevent simultaneous access).
> >
> > The intent is to document the existing contract, and to make it easy to find the
> > actions needed to convert the class to a pure single-threaded class.
