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
	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.  Added symbols argument to
	bfd_relax_section.  Removed bfd_seclet_link.  Added
	bfd_link_hash_table_create, bfd_link_add_symbols and
	bfd_final_link.
	* libaout.h (struct aoutdata): Added external_syms,
	external_sym_count, external_strings, sym_hashes fields.
	(obj_aout_external_syms, obj_aout_external_sym_count,
	obj_aout_external_strings, obj_aout_sym_hashes): New accessor
	macros.
	(WRITE_HEADERS): Only output symbols if outsymbols is not NULL.
	* aoutx.h: Wrote new back end linker routines.
	(translate_to_native_sym_flags): Return boolean value.  Don't use
	bfd_error_vector.
	(NAME(aout,write_syms)): Return boolean value.  Check return value
	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.
	* hp300hpux.c (MY(write_object_contents)): Likewise.
	* i386lynx.c (WRITE_HEADERS): Likewise.
	* libaout.h (WRITE_HEADERS): Likewise.
	* bout.c: Changed functions to use link_info->callbacks rather
	than bfd_error_vector, and link_orders rather than seclets.
	* coff-alpha.c: Likewise.
	* coff-h8300.c: Likewise.
	* coff-h8500.c: Likewise.
	* coff-sh.c: Likewise.
	* coff-z8k.c: Likewise.
	* elf32-hppa.c: Likewise.
	* reloc16.c: Likewise.
	* coff-alpha.c (alpha_ecoff_get_relocated_section_contents): Look
	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.
	(ecoff_bfd_final_link): Renamed from ecoff_bfd_seclet_link and
	rewritten.
	* elf32-mips.c (mips_elf_final_link): Renamed from
	mips_elf_seclet_link and rewritten.
	* elf32-hppa.c (elf32_hppa_stub_description): Added link_info
	field.
	(new_stub, add_stub_by_name, hppa_elf_build_arg_reloc_stub,
	hppa_elf_build_long_branch_stub, hppa_look_for_stubs_in_section):
	Added link_info arguments.  Changed all callers.
	* elfcode.h (elf_slurp_symbol_table): Don't quit if outsymbols is
	not NULL.
	* oasys.c (oasys_write_sections): Return boolean value rather than
	using bfd_error_vector.
	(oasys_write_object_contents): Check return value of
	oasys_write_sections.
