[libvirt] [PATCH 00/12] Remove devices only after DEVICE_DELETED event

This series (partially) fixes a longstanding bug in device unplug from a live domain. We considered the QEMU command used for that to be synchronous and removed the unplugged device from domain definition immediately after the command returned success. This is OK for USB devices but other devices actually need guest cooperation to be unplugged and thus they are actually unplugged asynchronously and QEMU tells us about that using DEVICE_DELETED event. This series is not complete, it does not check if any device finished unplug while libvirtd was not running. I'm working on that part but I wanted to get some feedback on this series as soon as possible. Path 3/12 explains how I decided to deal with backward compatibility of the virDomainDetachDeviceFlags API. No libvirt client/app should see any real difference in behavior after this series unless they want to.
