* src/abg-writer.h: Likewise.
* src/Makefile.am: Build the new files above.
* src/abg-ir.h (class location): Add public accessors for the value, and
a truth operator. Make the methods be inline.
(class decl_base): Renamed decl into this. Renamed what_decl_kind
into what_kind. Renamed get_context into get_scope. Add virtual
destructor, accessors for location and name.
(class {scope_decl, type_base, type_decl} ): Add virtual dtor.
Re-style.
(struct {decl_base_hash, type_decl_hash}): New hashing functors.

member.
(class type_base): Add data members proper and clean the iface up.
(class type_decl, scope_type_decl, namespace_decl): Iron out
constructors.
