[libvirt] [PATCH v2 0/7] PCI Multifunction hotplug/unplug, part 1

[Daniel Henrique Barboza]

v2:
- rebased without 3 patches from Michal that are under review
in his NVMe patch series

This is the first part of the feature discussed at [1]. These
patches are mostly cleanup and fixes, thus it is beneficial
to have them upstream right away.

The whole feature can be checked out at [2]. 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.
