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.

This reduces the source complexity of the html_mouse_action()
previously this was a single function of several thousand
lines with over 30 local variables allocated on the stack.
Variables are now mostly held in a single static structure which
drasticaly reduces the size of stack frame required and improves
lookup locality.
The generated code does cause two additional function calls as the
compiler avoids inlining the sub functions. The optimiser seems to
produce somewhat better code within the sub functions.
In the final analysis there appears to be no significant performance
loss or gain with this change, just more readable source.
In order to better model content close vs destroy, add the concept
of closing a thread to the JS interface.

Since it makes more sense for the htmlc to be responsible for
when the JS thread gets destroyed, move its lifetime from the
responsibility of the browser window to the html content.

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.

The async script completion process needs to complete the
content state machine so that browser throbbers eventually
stop once async scripts have fetched and run, even if that
happens *after* conversion finishes.

If there is more than one incomplete sync script then it's
important that we don't unpause hubbub too early. This commit
adds a counter so that if there're unfinished sync scripts in
the set, we don't unpause until the last one completes.

Fixes abort on exit when corestring finalisation tried to unref
what should have been the final ref:
$ ./nsgtk3
corrupted double-linked list
Aborted (core dumped)
HTML contents reference many other objects. The browser window
needs to know if any of them may not be secure, in which case it
needs to report that in its page state. If other content types
might refer to sub-contents, they will need to define the callback
too.
