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.
In what cases would we want to use this feature? The serial console is
not supported by all guests and I'm not sure it supports multiple
concurrent sessions (does it?), so it's probably not possible to use it
reliably as a replacement for the regular remote shell servers, or even
as an alternative variant.
We plan to push some network related tests in the next few weeks, so
it's important to use a serial based console rather than network based
one ( our test s may load/unload the nic driver, do the stress testing
which may cause the session created by remote_login() not responsible)

You probably meant to pass the prompt assist string to remote_login()
but instead you're passing "".
As I said, I just send a empty line in order to get the the prompt
string, but this may be removed if I logout the console during when
close the session.
