Extensive changes to move the bulk of the linker into BFD so that
more efficient backend code can be written for specific object files. Only existing efficient backend is a.out. * seclet.c, seclet.h: Removed. * hash.c, linker.c, genlink.h: New files. * bfd-in.h: Removed bfd_error_vector. Declared hash table structures and functions. (JUMP_TABLE): Removed bfd_seclet_link, added bfd_link_hash_table_create, bfd_link_add_symbols and bfd_final_link. * All backends: Changed accordingly. * bfd-in2.h: Rebuilt. * bfd.c (struct _bfd): Added link_next and archive_pass fields. Removed ld_symbols field. (bfd_nonrepresentable_section, bfd_undefined_symbol, bfd_reloc_value_truncated, bfd_reloc_is_dangerous, bfd_error_vector): Removed.

Declare internal linking functions. * libbfd.h: Rebuilt. * libbfd.c (bfd_seek): Comment out fseek assertion. It's worked for months. * reloc.c (reloc_howto_type): Added error_message argument to special_function field. Changed all callers and all definitions. (bfd_get_reloc_size): Make argument a const pointer. (bfd_perform_relocation): Add error_message argument to hold string set if return value if bfd_reloc_dangerous. Changed all callers. (_bfd_final_link_relocate, _bfd_relocate_contents): New functions. * section.c (asection): Renamed seclets_head and seclets_tail to link_order_head and link_order_tail. * targets.c (bfd_target): Replaced seclet argument with link_info and link_order and symbols arguments in bfd_get_relocated_section_contents.

DESCRIPTION
- If @var{output_bfd} is supplied to this function, the generated

- output file after they have been changed to reflect the new
- state of the world. There are two ways of reflecting the
- results of partial linkage in an output file: by modifying the
- output data in place, and by modifying the relocation record.
- Some native formats (e.g., basic a.out and basic coff) have no
- way of specifying an addend in the relocation type, so the
- addend has to go in the output data. This is no big deal
- since in these formats the output data slot will always be big
- enough for the addend. Complex reloc types with addends were
- invented to solve just this problem.
