[libvirt] [v8 0/6]Write separate module for hostdev passthrough

[Chunyan Liu]

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.

patch 1/6: extract hostdev passthrough function from qemu_hostdev.c and make it
reusable by multiple drivers.
patch 2/6: add a unit test for hostdev common library.
patch 3/6: switch qemu driver to use the common library instead of its own
hostdev passthrough APIs.
patch 4/6: switch lxc driver to use the common library instead of its own
hostdev passthrough APIs.
patch 5/6: add a hostdev pci backend type for xen usage.
patch 6/6: add pci passthrough to libxl driver.
