The network mode is specified by a NIC parameter named 'nic_mode'.
Currently two modes are supported: 'tap' and 'user'.
Other NIC parameters are now handled: nic_script, nic_downscript and
nic_ifname. nic_ifname should usually not be specified (qemu chooses one
automatically). nic_script and nic_downscript may specify a relative path,
e.g. 'qemu-ifup', which refers to a file in the KVM test local dir, or an
absolute path, e.g. '/etc/qemu-ifup'.
This patch mainly modifies VM.get_address(), VM.get_port() and
VM.make_qemu_command(), and adds a 'script_dir' parameter to several VM
routines. 'script_dir' should normally be the KVM test local dir.
