More fixes for invalid memory accesses triggered by fuzzed binaries.
PR binutils/17512 * nm.c (print_symbol): Add 'is_synthetic' parameter. Use it to help initialize the info.elfinfo field. (print_size_symbols): Add 'synth_count' parameter. Use it to set the is_synthetic parameter when calling print_symbol. (print_symbols): Likewise. (display_rel_file): Pass synth_count to printing function. (display_archive): Break loop if the last archive displayed matches the current archive. * size.c (display_archive): Likewise. * archive.c (do_slurp_bsd_armap): Make sure that the parsed sized is at least big enough for the header to be read. * elf32-i386.c (elf_i386_get_plt_sym_val): Skip unknown relocs. * mach-o.c (bfd_mach_o_get_synthetic_symtab): Add range checks. (bfd_mach_o_read_command): Prevetn duplicate error messages about unrecognized commands. * syms.c (_bfd_stab_section_find_nearest_line): Add range checks when indexing into the string table.
