* Support code for enabling the new style linker for PA ELF.

	* elfcode.h (swap_symbol_in, swap_symbol_out): Externalize.
	(elf_compute_section_file_positions): Pass link_info to
	the begin_write_processing hook.
	(bfd_elf_write_object_contents): Pass NULL for new link_info
	argument to final_write_processing hook.
	(elf_link_output_sym): Accept new "input_section" argument for
	the symbols's input section.  All callers changed.  Call the
	link_output_symbol_hook if it's defined.
	(elf_bfd_final_link): Call the final_write_processing hook if
	it's defined.
	* libelf.h (elf_backend_link_output_symbol_hook): Declare.
	(elf_backend_begin_write_processing): Add new "info" argument.
	(elf_backend_final_write_processing): Likewise.
	* elf32-target.h (elf_backend_link_output_symbol_hook): Provide
	a default definition.
	(elf32_bed): Add elf_backend_link_output_symbol_hook.
	* elf64-target.h: Likewise.

	* Major rework of the PA ELF code.  Uses the new style BFD
	linker, major cleanups.
	* hppa_stubs.h: Rewrite from scratch.  Much smaller and simpler.
	* elf32-hppa.h: Delete all symbol extension related code.
	(hppa_look_for_stubs_in_section): Delete decl.
	(elf32_hppa_size_stubs, elf32_hppa_build_stubs): New decls.
	* elf32-hppa.c: Symbol extension stuff moved form elf32-hppa.h
	into elf32-hppa.c.  Do not include aout64.h.
	(typdef hppa_stub_type): Delete.
	(elf32_hppa_stub_name_list_struct): Delete.
	(elf32_hppa_stub_description_struct): Delete.
	(arg_reloc_type): Use simpler enumerations.  All references changed.
	(arg_location, arg_reloc_relocation): Likewise.
	(elf32_hppa_symextn_map_struct): Delete.

	(elf32_hppa_backend_section_from_bfd_section): Delete.
	(NEW_INSTRUCTION): Delete.
	(CURRENT_STUB_OFFSET): Delete.
	(elf32_hppa_relocate_section): New function.
	(elf32_hppa_bfd_final_link_relocate): New function.
	(elf32_hppa_size_symext): New function.
	(elf32_hppa_link_output_symbol_hook): New function.

	(elf32_hppa_build_stubs): New function.
	(elf32_hppa_size_stubs): New function.
	(linker, stub and argument hash tables): Add appropriate
	structures, definitions and functions to implement all three
	hash tables.
	(hppa_elf_relocate_insn): Don't need argument location information
	in this function.
	(add_entry_to_symext_chain): Accept a symbol's argument location
	information rather than the symbol itself.  All callers changed.
	(hppa_elf_gen_reloc_type): Simplify.
	(hppa_elf_set_section_contents): Stub section is no longer special.
	(hppa_elf_reloc): Greatly simplify.
	(elf32_hppa_begin_write_processing): Accept link_info argument.
	Handle being called from the BFD backend linker.
	(elf32_hppa_final_write_processing): Likewise.
	(elf_hppa_tc_make_sections): No longer call stub_finish.
