Thanks for addressing this, @Bastian-Krause ! Seems indeed more adherent to the common design/usage patterns. I'll give it a closer look as soon as time permits. |

Since `qemu_version_mock` is required for all tests using `qemu_mock`, move its functionality into `qemu_mock`. Since `qemu_driver` will fixture will soon need `qemu_mock` always, add it as its dependency now, thus minimizing the direct fixtures required by the tests.

…e()/on_deactivate() Until now the QEMU process and QMP monitor start was tied to the on()/off() methods. This feels unnatural, preventing the user from interacting with the QEMU process via monitor commands before the emulation starts and meant starting a new process on each power cycle. Rework the driver to start QEMU and the QMP monitor in on_activate(), allowing interaction via monitor_command after activation. The on() and off() methods interact only via QMP now. All methods relying on a started QEMU and QMP monitor instance are decorated with @Driver.check_active now. The atexit handling is no longer required since the target's atexit handler already calls the driver's on_deactivate().

Now that the QEMU invocation is not only prepared, but also started in on_activate(), there is no need to keep the command around. Turn it into a local variable instead. Signed-off-by: Bastian Krause <bst@pengutronix.de>

Description
Until now the QEMU process and QMP monitor start was tied to the
on()/off()methods. This feels unnatural, preventing the user from interacting with the QEMU process via monitor commands before the emulation starts and meant starting a new process on each power cycle.Rework the driver to start QEMU and the QMP monitor in on_activate(), allowing interaction via
monitor_command()after activation. Theon()andoff()methods interact only via QMP now.All methods relying on a started QEMU and QMP monitor instance are decorated with
@Driver.check_activenow.The atexit handling is no longer required since the target's atexit handler already calls the driver's
on_deactivate().While at it, restructure the QEMU mock fixtures in the QEMUDriver tests.
