[PATCH 0/4] Introduce a battery, AC adapter, and lid button |

This series introduces the following ACPI devices:
* Battery
* AC adapter
* Laptop lid button
When running QEMU on a laptop, these paravirtualized devices reflect the
state of these physical devices onto the guest. This functionality is
relevant not only for laptops, but also for any other device which has e.g.
a battery. This even allows to insert a ``fake'' battery to the
guest, in a form of a file which emulates the behavior of the actual
battery in sysfs. A possible use case for such a ``fake'' battery can be
limiting the budget of VM usage to a subscriber, in a naturally-visible way.
But of course, the main purpose here is addressing the desktop users.
This series was tested with Windows and (desktop) Linux guests, on which
indeed the battery icon appears in the corresponding state (full,
charging, discharging, time remaining to empty, etc.) and the AC adapter
plugging/unplugging behaves as expected. So is the laptop lid button.
For the ease of review, these commits are also available here:

Thanks,
Leonid.
