Fixes for memory access violations exposed by fuzzinf various binaries.

	PR binutils/17512
	* dwarf.c (get_encoded_value): Check for an encoded size of 0.
	(display_debug_lines_raw): Check for an invalid line range value.
	(display_debug_frames): Check for corrupt augmentation data.

	* coffgen.c (coff_get_normalized_symtab): Check for an excessive
	number of auxillary entries.
	* ieee.c (next_byte): Convert to a function.  Return FALSE if the
	next byte is beyond the end of the buffer.
	(parse_int): Test the return value of next_byte.
	(parse_expression): Convert to boolean.  Return FALSE if the
	parsing failed.  Test the return value of next_byte.
	(ieee_seek): Convert to a function.  Return FALSE if the seek goes
	beyond the end of the buffer.
	(ieee_slurp_external_symbols): Test the return value of ieee_seek
	and next_byte.
	(ieee_slurp_sections): Convert to boolean.  Return FALSE if the
	operation failed.  Test the return value of ieee_seek and
	next_byte.
	(ieee_archive_p): Test the return value of ieee_seek and
	next_byte.
	(do_one): Likewise.
	(ieee_slurp_section_data): Likewise.
	(ieee_object_p): Likewise.  Store the size of the buffer in the
	total_amt field in the header.
	* libieee.h (common_header_type): Add amt field.
	* mach-o.c (bfd_mach_o_canonicalize_one_reloc): Check that the
	reloc's value is within range.
	(bfd_mach_o_read_symtab_symbols): Nullify the symbols field if the
	operation fails.
	* pei-x86_64.c (pex64_xdata_print_uwd_codes): Replace abort with
	an error message.
	(pex64_dump_xdata): Check for buffer overflows.
	* versados.c (process_otr): Check that the section exists before
	taking its size.
	(versados_object_p): Make sure that enough data was read for the
	header to be checked.
	* vms-alpha.c (vms_get_remaining_object_record): Change
	read_so_far parameter to an unsigned int.  Check that the amount
	read is in range.
