	Simple functions/variables for use in tools.

	ostr = option string. Comprises single letter options, followed by : if there
	is an argument to the option.

	longopts: NULL (indicating no long options), or a pointer to an array of
	longoptions, terminated by an entry with option == NULL.

	In the event of matching a single char option, this function will normally
	return the char. The exception to this is when the option requires an
	argument and none is supplied; in this case we return ':'.

	In the event of matching a long option, this function returns 0, with fz_optlong
	set to point to the matching option.

	A long option entry may be followed with : to indicate there is an argument to the
	option. If the need for an argument is specified in this way, and no argument is
	given, an error will be displayed and argument processing will stop. If an argument
	is given, and the long option record contains a non-null flag pointer, then the code
	will decode the argument and fill in that flag pointer. Specifically,
	case-insensitive matches to 'yes', 'no', 'true' and 'false' will cause a value of 0
	or 1 as appropriate to be written; failing this the arg will be interpreted as a
	decimal integer using atoi.

	A long option entry may be followed by an list of options (e.g. myoption=foo|bar|baz)
	and the option will be passed to fz_opt_from_list. The return value of that will be
	placed in fz_optitem. If the return value of that function is -1, then an error will
	be displayed and argument processing will stop.

	In the event of reaching the end of the arg list or '--', this function returns EOF.

	In the event of failing to match anything, an error is printed, and we return '?'.

	If an argument is expected for the option, then fz_optarg will be returned pointing
	at the start of the argument. Examples of supported argument formats: '-r500', '-r 500',
	'--resolution 500', '--resolution=500'.
