by having a vmid <-> pciid mapping in /var/run
i did not check if the vm has the pci device really in the config,
but we should not need that, since we remove the reservation again
in the cleanup step and check the running pid anyway.

changes from v1:
* use time-based reservation before starting (current + start timeout +5s)
  and reserve again after we have the pid

Dominik Csapak (2):
  pci: add helpers to (un)reserve pciids for a vm
  fix #3258: block vm start when pci device is already in use
