4c3721d514 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.
	(bfd_default_error_trap, bfd_error_trap,
	bfd_error_nonrepresentabltrap): Removed.
	(bfd_get_relocated_section_contents): Pass link_info.  Pass
	link_order instead of seclet.  Pass symbols.
	(bfd_relax_section): Pass link_info.
	(bfd_seclet_link): Removed.
	(bfd_link_hash_table_create, bfd_link_add_symbols,
	bfd_final_link): New macros.
	* libbfd-in.h: If __GNUC__ is defined and alloca is not, define
	alloca as __builtin_alloca.  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

	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.

	and link_order and symbols arguments in

	bfd_relax_section.  Removed bfd_seclet_link.  Added
	bfd_link_hash_table_create, bfd_link_add_symbols and

	macros.
	(WRITE_HEADERS): Only output symbols if outsymbols is not NULL.

	of translate_to_native_sym_flags and bfd_write.
	* aout-target.h (final_link_callback): New function.
	(MY_bfd_final_link): New function.
	* aout-adobe.c (aout_adobe_write_object_contents): Check return
	value of aout_32_write_syms.

	up _gp in the hash table rather than in outsymbols.
	* coff-a29k.c (a29k_reloc): Pass errors back in new error_message
	argument rather than printing them.
	* coffcode.h (bfd_coff_reloc16_extra_cases): Take link_info and
	link_order arguments rather than seclet.  Changed all uses and
	definitions.
	(bfd_coff_reloc16_estimate): Pass link_info arguments.  Changed
	all uses and definitions.
	* libcoff.h: Rebuilt.
	* ecoff.c (ecoff_get_extr): If symbol is defined by linker, but
	not by ECOFF, make it scAbs.
