Make walk_dom_nodes() use a stack context; reduces the DOM stack state size

Make it easier to work with DOM stack contexts outside of the callbacks
...
The problem is to get access to the context when it is not the first one
and it has to happen outside of the context callbacks. This changes the
memory management so that the context adder returns the context. To further
improve the use of contexts add a context destructor which makes it
possible to unregister (temporary) contexts.

Simplify DOM node popping
...
.. by turning do_pop_dom_node() into pop_dom_node() and let pop_dom_state()
handle it's own logic for reaching the wanted state.

Rename DOM stack iterators and make them include all states when iterating

They are now called: foreach{back,}_dom_stack_state (...) and the immutable

the document root node never is popped.

It's basically pop_dom_nodes() without the search part and is now used as a

DOM stack searches in a row.

Fix access to free()d memory in the DOM stack state data
...
There already was one work-around in the code related to clearing of the
state data after popping. Instead of storing a pointer to the state data in
the state we now store the depth of the state (in the stack) and use a
macro to access the state data. The bug occurred when reallocating the
stack state objects and the stack data pointers wasn't updated to point to
the newly allocated data.

Rename DOM navigator -> stack
...
This is really a much more appropriate word since it never ended up being
more than just a stack. The rename also changes the symbol names to use the
much shorter "stack".
