When we close the JS compartment we try and cancel all callbacks so that
they do not fire after the compartment is closed. However if we have
in-train callbacks, they can gum up the closedown and so we need to check
and if we've done all we can, we break out of the callback removal loop.

In order to better model content close vs destroy, add the concept
of closing a thread to the JS interface.

In order to cope with threads which manage to navigate entirely
while executing (sadly possible) we need to handle the possibility
that a thread is destroyed by the browser but still needs to live
until it returns from whatever exec it was doing at the time.

Update the duktape bindings and dukky interface to support the
new JS heap/thread split. Heaps may have multiple active threads
though in general there will only be 2 at a time.

In preparation for proper splitting of Javascript support into
heaps and threads, this renames the types and corrects the no-js
builds to still work. At this time no substantive change in
semantics exists, and the duktape build won't work.

This is a *very* rudimentary implementation lacking most of the
functionality of NamedNodeMap but it's enough to get jQuery 1.12.4 up.

To get us further along the JavaScript pathway, support the
getter and setter for innerHTML. The getter always returns
an empty string for now, but the setter works.

Normal, and verbose logging will now also log all JS errors in order that we
stand a chance of debugging things more easily when testing.

By reference to the MDN and to Duktape's CLI, expose everything
we possibly can on the global object (Window).

Add a polyfill for Array.from(), and fix the console formatter so that
it won't keep exploding. This should improve matters in the tests.

Sometimes callbacks may be cancelled from within themselves. In
that case we need to simply ensure that should the callback be
wanted to repeat, we instead stop that so that once the callback
is completed we do not attempt to reschedule something which had
already been deleted.
