Currently, the commit test just use qemu_img, which
install in the system as default, to make the backup
file, and use the qemu_img_binary which get the path
from env file. Thus may bring some bugs.

For example, if just use the qemu source code and
don't make install to the system(that means the
system haven't installed a qemu to /usr/local/bin
or other system bin path, and autotest just test
the qemu using the git tree), the test will not
find the qemu_img_binary to create the backing_file.

and another problem is the binary used to backup and
commit may be different version, this may cause a bug.

To solve the problem, make the same binary to backup
and commit.

This test starts loopback between first 2 ports and do the interruption.
Than it verifies, whether new data still arrives and the loss/dup is
in the allowed range. Multiple interruption loops are supported.

Variants:
* stop and cont

This patch adds _reconnect_none_mode version of the loopback thread.
It works as ordinary none_mode, but additionally disconnects in case
the port is unreadable and reconnects when possible.

It was necessarily to make virt global variable to be able to access
it in this thread.

This patch adds new features to GuestWorker:
* read_nonblocking - read-out the output of guest script (used when
                     the test fails and we want to see the output)
* ThSendCheck - adds reduced_set option (use only A-Z, simplifies debuging
* ThRecvCheck - adds debug mode. This mode executes completely different
                loop. It's better for debuging purposes. Not all
                functionalities are kept so you should know when you want
                to use it.

This patch changes the GuestWorker to run on windows and adjusts
virtio_console test also to support windows testing.

Currently supported tests are:
* open
* multiopen
* close
* max_serials_and_conosles (windows won't initialize consoles. I need
           to check it with the developer if this is a bug or feature)
* rw_host_offline (fails, need to check with developer the expected
                   results)
* basic_loopback (fails, data are corrupted)
* loopback (fails, data are corrupted)
* migrate (fails, data are corrupted)
* hotplug (fails, windows won't initialize consoles properly)
* shutdown

Beware on my laptop in 50% the ports were not initialized properly,
VM reboot usually helped (not always). You might use "Winobj" program
to list \\Device\vport* ports or \\.\$port_name devices/symlinks.

I checked the data corruption and it happends (winXP->Fedora18)
pretty regularly even with Amit's C++ testing script.

It's a first very limited version.

VirtioGuest class now contains all functions, which might be used in

The Nt version is simplified version which currently doesn't support

features.
