These patches implements a separate module for hostdev passthrough so that it
could be shared by different drivers and can maintain a global state of a host
device.
Patches 1~6 are to switch existing qemu and lxc driver to use common library
lists, so that to maintain a global state of every host device.
Patches 7~45 are to extract general code from qemu_hostdev.c piece by piece,
make them reusable common APIs.
Patches 46: unit test for the virhostdev common library
Patches 47: add a hostdev backend type for xen
Patches 48: add pci passthrough to libxl driver based on the common library
Patches 49: change lxc to use common library APIs

changes to v12:
* split "add hostdev passthrough common library" patch into small patches
for easier review.
* fix v12 comments
* rebase to libxl changes
