PCID server used if domain has passthrough PCI controller and we wants
assign some device to other domain.
pcid server should be launched in domain owns the PCI controller and process
request from other domains.
pcid server needs if domain which owns the PCI controller is not Domain-0.
Changes:
patch with subject "remove xenstore entries on vchan server closure" removed
from patchset because it already merged.
patch with subject "Add pcid daemon to xl" divided on several patches because
it was very large.
Fixed crash in some cases
Fixed memory leak
Fixed false client detection.
