wintest Add testing of kerberos connections to Windows members of an AD domain

This improves the Samba3 wintest script to test against Windows7 and
WinXP domain members, and Windows7 standalone servers.  To do this,
more of the samba4 script is put in common, and we splut up the
starting of the VMs from the preperation of the VM.

This also improves the nmblookup command parsing to cope with both the
samba3 and samba4 nmblookup commands.

A krb5.conf is now provided for both s3 and s4 tests.
