[libvirt] [PATCH v1 00/10] PCI Multifunction hotplug/unplug, part 1

This is the first part of the feature discussed at [1]. With the exception of patch 06, these patches are aimed into preparing the existing unit test infrastructure for the more sofisticated multifunction tests to come. First 3 Michal's patches helped me with unit test issues in the first 3-4 patches (see [2] for more info), thus I am relying on them being upstreamed as well. The whole feature can be checked out at [3]. All patches survives unit testing. The feature was stress tested with hundreds of consecutive hotplug/unplugs of a Broadcom BCM5719 multifunction network card in a guest running in a Power 8 server. Hopefully I'll find a suitable x86 env to stress test the feature there too.
