* sec_helper.cc (cygsid::getfrompw): Change parameter to `const'.

Browse Source 
(cygsid::getfromgr): Ditto.
        * security.cc: Use `sys_mbstowcs' and `sys_wcstombs' throughout.
        (extract_nt_dom_user): Try to get user and domain from SID in
        pw->pw_gecos first.
        * security.h (class cygsid): Change parameter of getfrompw() and
        getfromgr() to `const'.
        * uinfo.cc (internal_getlogin): Change order for evaluating user
        information in winNT case. Drop usage of NetWkstaUserGetInfo().
