Add tests for the handling of non-option arguments, "--" and

	* tests/option-test.c: Add tests for the handling of
	non-option arguments, "--" and G_OPTION_REMAINING.

	* glib/goption.[hc]: #define G_OPTION_REMAINING, which is
	a special long option name, which can be used for an option
	in the main group which collects the non-option arguments.
	It must be of type G_OPTION_ARG_STRING_ARRAY or
	G_OPTION_ARG_FILENAME_ARRAY. If the main group doesn't contain
	an option whose name is G_OPTION_REMAINING, the non-option
	arguments are left behind in argv as before.
