Enhance the format of the diff tree dumping report

Browse Source 
This patch changes the format of the diff tree dumping report emitted
by abidiff --dump-diff-treee to make it more hierachical and also add
two new properties: the address of the diff tree node and the address
of its canonical diff tree node.

	* src/abg-comparison.cc (diff_node_printer::do_indent): New
	method.
	(diff_node_printer::visit): Use diff_node_printer::do_indent().
	Print the addresses of the diff tree node and its canonical node.
	Add some vertical spaces and some indenting to make the report
	more readable.
