We add the ConsoleSocket object, which has a socket interface
and which will consume all arriving characters on the
socket, placing them into an in memory buffer.
This will also provide those chars via recv() as
would a regular socket.
ConsoleSocket also has the option of dumping
the console bytes to a log file.
We also give QEMUMachine the option of using ConsoleSocket
to drain and to use for logging console to a file.
By default QEMUMachine does not use ConsoleSocket.
This is added in preparation for use by basevm.py in a later commit.
This is a workaround we found was needed for basevm.py since
there is a known issue where QEMU will hang waiting
for console characters to be consumed.

With a QEMU bug, it can happen that the QEMU process doesn't react to a
'quit' QMP command. If we got an exception during previous QMP
communication (e.g. iotests Timeout expiring), we could also be in an
inconsistent state where after sending 'quit' we immediately read an old
response and close the socket even though the 'quit' command wasn't
processed yet. Both cases would lead to a hanging test.
Fix this by waiting for the QEMU process to exit after sending 'quit'
with a timeout, and if it doesn't happen within three seconds, send
SIGKILL.

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.

Before, event_match didn't always recurse if the event value was not a
dictionary, and would instead check for equality immediately.
By delaying equality checking to post-recursion, we can allow leaf
values like "5" to match "None" and take advantage of the generic
None-returns-True clause.
This makes the matching a little more obviously consistent at the
expense of being able to check for explicit None values, which is
probably not that important given what this function is used for.

The set_console() utility function either adds a device based on the
explicitly given device type, or adds a known good type of device
based on the machine type.
But, for a number of machine types, it may be impossible or
inconvenient to add the devices by means of "-device" command line
options, and then it may better to just use the "-serial" option and
let QEMU itself, based on the machine type, set the device
accordingly.
To achieve that, the behavior of set_console() now flags the intention
to add a console device on launch(), and if no explicit device type is
given the "-serial" option is going to be added to the QEMU command
line, instead of raising exceptions.
Based on testing with different machine types, the CONSOLE_DEV_TYPES
is not necessary anymore, so it's being removed, as is the logic to
use it.

Even when the launch of QEMU succeeds, it's useful to have the command
line recorded.

This is a simple move of Python code that wraps common QEMU
functionality, and are used by a number of different tests
and scripts.
By treating that code as a real Python module, we can more easily:
* reuse code
* have a proper place for the module's own unittests
* apply a more consistent style
* generate documentation
