* objdump.c (disassemble_all): New global variable.

	(usage): Document --disassemble-all.
	(long_options): Add disassemble-all as a synonym for -D.
	(compare_symbols): Make pointers const.
	(compare_relocs): New static function.
	(disassemble_data): Rename disassemble to disassemble_fn to avoid
	shadowing.  If dump_reloc_info, print relocs along with
	disassembly.  Skip sections which are not SEC_CODE unless
	disassemble_all or only is set.
	(display_bfd): Don't call dump_relocs if disassemble is set.
	(main): Accept and handle -D.
	* binutils.texi: Document -D/--disassemble-all.
	* objdump.1: Likewise.
