If tests use a TCP based monitor socket, the connection will
go into a TIMED_WAIT state when the test exits. This will
randomly prevent the test from being re-run without a certain
time period. Set the SO_REUSEADDR flag on the socket to ensure
we can immediately re-run the tests

If QEMU fails to launch for some reason, the QEMUMonitorProtocol
class accept() method will wait forever in a socket accept call.
Set a timeout of 15 seconds so that we fail more gracefully
instead of hanging the test script forever

PEP 8 calls for it, because it's forward compatible with Python 3.
Supported since Python 2.6, which we require (commit fec2103).

A filter is added to allow callers to request very specific
events to be pulled from the event queue, while leaving undesired
events still in the stream.
This allows us to poll for completion data for multiple asynchronous
events in any arbitrary order.
A new timeout context is added to the qmp pull_event method's
wait parameter to allow tests to fail if they do not complete
within some expected period of time.
Also fixed is a bug in qmp.pull_event where we try to retrieve an event
from an empty list if we attempt to retrieve an event with wait=False
but no events have occurred.

When QEMU process aborts and socket is closed, qmp client will not
detect it. When this happens, some qemu-iotests scripts will enter an
endless loop waiting for qmp events.
It's better we raise an exception in qmp.py to catch this and make the
test script stop.
