Pimpl-ify traversable_base and remove its unused traverse method
The traverse method is defined in the traversable_base class but is
never used as the synonymous methods in the derived classes have
different argument types and so hide it.
It's never used because it's mostly intended as documentation for what
the implementations of this interface should look like. Namely they
should define a traversable method and its parameter type should
derive from the parameter type of traversable_base::traverse.
But apparently, clang's -Werror-overloaded-virtual is not happy about
this. It flags it as an error. It's not. But hey, let's work-around
it then.
So this patch just comments that method out and document its intent.
To make the change somewhat useful, this patch pimpl-ifies this
abg-traverse.h header file to get us one step closer to some a{b,p}i
stability. The definitions are moved into abg-traverse.cc.
* include/abg-traverse.h (traversable_base::priv): Declare new type.
(traverse_base::priv_sptr): Add pointer to private data
member.
(traverse_base::visiting_): Move this data member definition into
traverse_base::priv.
(traverse_base::{visiting, traverse_base, ~traverse_base}): Move
definitions out-of-oline.
(traverse_base::traverse): Comment out.
* src/abg-traverse.cc (struct traversable_base::priv): Define new
type.
(traversable_base::{traversable_base, ~traversable_base, traverse,
visiting}): Move these previous inline definitions here.
