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. Plus, add passthrough to libxl driver, and change qemu driver and lxc
driver to use hostdev common library instead of their own hostdev APIs.
---
Changes to v5:
* For upgrade concern, check netconfig file in old stateDir xxx/qemu/ if it's
not found in new location xxx/hostdevmgr/, since if there is existing VM,
then after upgrade, NetConfigRestore should find the netconfig file from old
stateDir place.
* Rebase to new qemu_hostdev changes, e.g, prefer VFIO, and add CheckSupport.
* Put into separate patches for adding a pci backend type for xen and other
hostdev common library stuff
* Other fixes according to Daniel's comments.
