* autoload.cc: Add load statements for `LookupAccountNameW',

Browse Source 
`LsaClose', `LsaEnumerateAccountRights', `LsaFreeMemory',
        `LsaOpenPolicy', `LsaQueryInformationPolicy', `NetLocalGroupEnum',
        `NetLocalGroupGetMembers', `NetServerEnum', `NetUserGetGroups' and
        `NtCreateToken'.
        * ntdll.h: Add declaration for `NtCreateToken'.
        * sec_helper.cc: Add `well_known_local_sid', `well_known_dialup_sid',
        `well_known_network_sid', `well_known_batch_sid',
        `well_known_interactive_sid', `well_known_service_sid' and
        `well_known_authenticated_users_sid'.
        (cygsid::string): Define as const method.
        (cygsid::get_sid): Set psid to NO_SID on error.
        (cygsid::getfromstr): Ditto.
        (cygsid::getfrompw): Simplify.
        (cygsid::getfromgr): Check for gr == NULL.
        (legal_sid_type): Move to security.h.
        (set_process_privilege): Return -1 on error, otherwise 0 or 1 related
        to previous privilege setting.
        * security.cc (extract_nt_dom_user): Remove `static'.
        (lsa2wchar): New function.
        (open_local_policy): Ditto.
        (close_local_policy): Ditto.
        (get_lsa_srv_inf): Ditto.
        (get_logon_server): Ditto.
        (get_logon_server_and_user_domain): Ditto.
        (get_user_groups): Ditto.
        (is_group_member): Ditto.
        (get_user_local_groups): Ditto.
        (sid_in_token_groups): Ditto.
        (get_user_primary_group): Ditto.
        (get_group_sidlist): Ditto.
        (get_system_priv_list): Ditto.
        (get_priv_list): Ditto.
        (get_dacl): Ditto.
        (create_token): Ditto.
        (subauth): Return immediately if SE_TCB_NAME can't be assigned.
        Change all return statements in case of error to jumps to `out'
        label. Add `out' label to support cleanup.
        * security.h: Add extern declarations for `well_known_local_sid',
        `well_known_dialup_sid', `well_known_network_sid',
        `well_known_batch_sid', `well_known_interactive_sid',
        `well_known_service_sid' and `well_known_authenticated_users_sid'.
        Add extern declarations for functions `create_token',
        `extract_nt_dom_user' and `get_logon_server_and_user_domain'.
        (class cygsid): Add method `assign'. Change operator= to call new
        `assign' method. Add `debug_print' method.
        (class cygsidlist): New class.
        (legal_sid_type): Moved from sec_helper.cc to here.
        * spawn.cc (spawn_guts) Revert reversion of previous patch.
        Call `RevertToSelf' and `ImpersonateLoggedOnUser' instead of `seteuid'
        again.
        * syscalls.cc (seteuid): Rearranged. Call `create_token' now when
        needed. Call `subauth' if `create_token' fails. Try setting token
        owner and primary group only if token was not explicitely created
        by `create_token'.
        * uinfo.cc (internal_getlogin): Try harder to generate correct user
        information. Especially don't trust return value of `GetUserName'.
