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.
