To interact with the FVP (for example entering the U-Boot shell
and transferring the files by TFTP), we need to connect the
corresponding port by the telnet first. Use an expect script to
simplify the automation of the whole "interacting with FVP" stuff.
The expect script will firstly detect the IP of the host, then
connect to the telnet port of the FVP, set the `serverip` and `ipaddr`
for the TFTP service in the U-Boot shell, and finally boot Xen from
U-Boot and wait for the expected results by Xen, Dom0 and DomU.
