Dodji Seketeli 49db3f838c Plug leak of diffs of member variables of class type 
On certain work loads, cycles in the tree of diffs of member variables
can appear.  This because:

  1/ each diff tree nodes holds a reference on each of its children
  nodes
  2/ each var_diff tree node holds a reference on the diff tree node
  representing its type changes.

There can thus be reference cycles in involving diff the tree --> child
node relationship and the var_diff tree --> type diff tree
relationship.

This patch fixes the issue be make sure that a diff tree node does not
hold a reference on its children nodes.  That is, rather than having a
vector of shared pointers to its children diff nodes, it has a vector
of naked pointers to those.  The patch goes further by making sure
that a var_diff node does not hold a reference to its type diff node
either.  It holds a weak pointer to the type diff node, rather than a
shared pointer.

The patch should be followed by a patch make sure that all kinds of
diff nodes follow this pattern; that is, if a diff node needs to carry
a sub-type diff node, it should do so by either using a naked pointer
to the sub-type diff node, or a weak pointer.

For now, the patch fixes the leaks reported by running all the tests
of the suite under Valgrind.

	* include/abg-comparison.h (diff_wptr, unordered_diff_sptr_set): New typedefs.
	(struct diff_sptr_hasher): Define new type.
	(diff_context::keep_diff_alive): Declare new member function.
	(diff::children_nodes): Return a vector of diff*, rather than a
	vector of diff_sptr.
	* src/abg-comparison.cc (diff_context::priv::live_diffs_): New
	data member.
	(diff_context::keep_diff_alive): Define new data member.
	(diff::priv::children_): Make this be a vector of diff*, rather
	than a vector of diff_sptr.
	(diff_less_than_functor::operator()): Add a new overload for
	diff*.  Make the existing overload of diff_sptr use the new one.
	(diff::children_nodes): Adjust;
	(diff::append_child_node): Make sure the child node is kept
	alive.  Only add the naked pointer to the child node to the vector
	of children.
	(diff::traverse): Adjust.
	(var_diff::priv::type_diff_): Make this be a weak pointer, rather
	than a shared pointer.
	(var_diff::type_diff): The var_diff::priv::type_diff_ data member
	is now a weak pointer, so make this accessor convert it to a
	shared pointer.
	(corpus_diff::priv::children_): Turn this into a vector of diff*,
	rather than a vector of diff_sptr.
	(corpus_diff::children_nodes): Adjust.
	(corpus_diff::append_child_node): Make sure the child node is kept
	alive.  Only add the naked pointer to the child node to the vector
	of children.
	(category_propagation_visitor::visit_end): Adjust.
	(suppression_categorization_visitor::visit_end): Adjust.
	(redundancy_marking_visitor::{visit_begin, visit_end}): Adjust.
