From: Chunyan Liu <cyliu at suse.com>

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 v2:
  * add patches for qemu driver and lxc driver, use common library APIs instead
    of their own hostdev APIs.
  * add APIs for nodedev-detach and nodedev-reattach calling.
  * rename functions to use unified prefix 'virHostdev'
  * use VIR_ONCE_GLOBAL_INIT() as others instead of previous Init and Cleanup.
  * use VIR_STRDUP instead of strdup
  * rebase to latest code
  v2 is here:

Chunyan Liu (4):
  add hostdev passthrough common library
  add pci passthrough to libxl driver
  change qemu driver to use hostdev common library
  change lxc driver to use hostdev common library
