Currently the QEMU Python module limits the QEMUMachine class to
use the first serial console.
Some machines/guest might use another console than the first one as
the 'boot console'. For example the Raspberry Pi uses the second
(AUX) console.
To be able to use the Nth console as default, we simply need to
connect all the N - 1 consoles to the null chardev.
Add an index argument, so we can use a specific serial console as
default.

The QEMUMachine VM has a monitor setup on which an QMP
connection is always attempted on _post_launch() (executed
by launch()). In case the QEMU process immediatly exits
then the qmp.accept() (used to establish the connection) stalls
until it reaches timeout and consequently an exception raises.
That behavior is undesirable when, for instance, it needs to
gather information from the QEMU binary ($ qemu -cpu list) or a
test which launches the VM expecting its failure.
This patch adds the set_qmp_monitor() method to QEMUMachine that
allows turn off the creation of the monitor machinery on VM launch.

Currently, the console socket on QEMUMachine is closed after the QMP
command to gracefully exit QEMU is executed. Because of a possible
deadlock (QEMU waiting for the socket to become writable) let's close
the console socket earlier.

iotests.py itself does not store socket files, but machine.py and
qtest.py do. iotests.py needs to pass the respective path to them, and
they need to adhere to it.

If a test has issued a quit command already (which may be useful to do
explicitly because the test wants to show its effects),
QEMUMachine.shutdown() should not do so again. Otherwise, the VM may
well return an ECONNRESET which will lead QEMUMachine.shutdown() to
killing it, which then turns into a "qemu received signal 9" line.

Since we're out in a new module, do a quick cursory pass of some of the

It's not obvious that something named __init__.py actually houses
important code that isn't relevant to python packaging glue. Move the
QEMUMachine and related error classes out into their own module.
Adjust users to the new import location.
