* section.c (bfd_section_list_remove): Don't clear s->next.
(bfd_section_list_append): Always init s->prev.
(bfd_section_list_prepend): Define.
(bfd_section_list_insert_after): Minor optimization.
(bfd_section_removed_from_list): Rewrite.
* elf.c (assign_section_numbers): Simplify list traversal now that
bfd_section_list_remove doesn't destroy removed section next ptr.
* sunos.c (sunos_add_dynamic_symbols): Likewise.
* elfxx-ia64.c (elfNN_ia64_object_p): Use bfd_section_list_prepend.
* xcofflink.c (_bfd_xcoff_bfd_final_link): Simplify list traversal.
* bfd-in2.h: Regenerate.
