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.

We've got a separate option to configure the accelerator nowadays, which
is shorter to type and the preferred way of specifying an accelerator.
Use it in the source and examples to show that it is the favored option.
(However, do not touch the places yet which also specify other machine
options or multiple accelerators - these are currently still better
handled with one single "-machine" statement instead)

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.

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.

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
