s4:dsdb/rootdse: Support netlogon request
This patch adds support for a netlogon ldap style request
over the tcp socket. This is available since win2k3+ [1].
The automatic client join & configuration daemon "realmd" makes
use of this ability.
Realmd can now be used to join a computer to a samba 4 domain.

Tested with:
ldapsearch -h samba-srv -x -b '' -s base "(&(NtVer=\06\00\00\00)(AAC=\00\00\00\00))" NetLogon
And compared the result in wireshark with cldap request issued by
examples/misc/cldap.pl.
