* mkgroup.c: Use statically linked functions throughout, except for

	DsGetDcNameW.  Reformat.  Convert to use WCHAR for names throughout.
	Use defines instead of constants throughout.
	(MAX_SID_LEN): Define.
	(load_netapi): Just load DsGetDcNameW pointer.
	(psx_dir): Remove.
	(uni2ansi): Remove.
	(enum_local_users): Take server name and use in Net... call.
	(DBGSID): Define datastructure.
	(MAX_BUILTIN_SIDS): Define.
	(builtin_sid_list): Define global sid list.
	(builtin_sid_cnt): Define counter for global sid list.
	(enum_local_groups): Take server name and use in Net... and Lookup...
	calls.  Take offset argument.  Use MAX_PREFERRED_LENGTH in call to
	NetLocalGroupEnum.  Check for duplicate builtin groups.
	(enum_users): Take server name and use in Net... call.
	(usage): Change text slightly.
	(print_version): Fix copyright.
	(main): Call enum_local_groups for domains as well.
	* mkpasswd.c: Use statically linked functions throughout, except for
	DsGetDcNameW.  Reformat.  Convert to use WCHAR for names throughout.
	Use defines instead of constants throughout.
	(MAX_SID_LEN): Define.
	(load_netapi): Just load DsGetDcNameW pointer.
	(uni2ansi): Use wcstombs.
	(current_user): Replace "unused_by_nt/2000/xp" by
	just "unused".
	(enum_users): Ditto.
	(print_version): Fix copyright.
