* mkpasswd.c: include lmerr.h (main): New -u option to allow specifying a specific user. If specified, groups aren't displayed and output is limited to only the specified user. (enum_users): If specific user is specified, via -u option, display only that user's record. With -u use NetUserGetInfo instead of NetUserEnum. (load_netapi): Added netusergetinfo.
