* autoload.cc (DsGetDcNameW): Replace DsGetDcNameA.
* dcrt0.cc (child_info_spawn::handle_spawn): Drop artificial
supplementary group list from calling setgroups in parent.
* grp.cc (internal_getgroups): Drop 9x-only code. Reformat.
* sec_auth.cc (get_logon_server): Do everything in WCHAR only.
(get_user_groups): Ditto. Use wlogonserver in LookupAccountNameW
calls, too.
(is_group_member): Get logon server as first argument and use in call
to NetLocalGroupGetMembers.
(get_user_local_groups): Get logon server as first argument and use in
calls to NetLocalGroupEnum and LookupAccountNameW. Revamp to work
more correctly in domain environments.
(get_server_groups): Accommodate aforementioned changed function calls.
* security.h (get_logon_server): Change prototype accordingly.
* uinfo.cc (cygheap_user::env_logsrv): Accommodate changed
get_logon_server call.
