[libvirt] [PATCH v2 0/2]impl separite module for hostdev passthrough



This patch series include two patches:
1/2 is the implementation of the hostdev passthrough common library.
To meet two purposes:
a. move qemu hostdev APIs to common library so that it could be used by all
   hypervisor drivers.
b. maintain a global hostdev in-use state.

2/2 is the implementation of pci passthrough to libxl driver.
Using common library APIs to implement pci passthrough for libxl driver.
(Changes to qemu/lxc driver are not included yet. That could be done after common
library is confirmed.)


Changes to v1:
1/2: 
*  add scsi part to common library
*  instead of hardcode, check for <driver name='kvm/vfio/xen'/> setting, call
   virPCIDeviceSetStubDriver to set stub driver. For libxl driver, a <driver
   name='xen' /> is needed.
*  rebase to current libvirt changes

2/2: 
* Add device-attach/detach a pci hostdev implementataion to libxl driver 


Chunyan Liu (2):
  add hostdev passthrough common library
  add pci passthrough impl to libxl
