Oksana Vohchana 566054a0bc python/qemu/qmp.py: QMP debug with VM label
QEMUMachine writes some messages to the default logger.
But it sometimes hard to read the output if we have requests to
more than one VM.
This patch adds a label to the logger in the debug mode.

Lukáš Doktor 52c68b8abb python: Treat None-return of greeting cmd
In case qemu process dies the "monitor.cmd" returns None which gets
passed to the "__negotiate_capabilities" and leads to unhandled
exception. Let's only check the resp in case it has a value.

Wainer dos Santos Moschetta 54aafc2fc6 python/qemu: qmp: Make accept()'s timeout configurable
Currently the timeout of QEMUMonitorProtocol.accept() is
hard-coded to 15.0 seconds. This added the parameter `timeout`
so the value can be configured by the user.

Cleber Rosa 8f8fd9edba Introduce a Python module structure
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
