This patch introduces a new method which is used to log into the guest
through the guest serial console. The serial_mode must be set to
"session" in order to make use of this patch. Serial does not support
cocurrent sessions, so it doest not aim at replacing the regular
remote shell servers. But it would be useful for the network related
test which may cause the network unresponsive such as driver
load/unload or some kinds of network stress testing.
