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: fix memory leak in virscsi.c
Patch 2: improve virHostdevManager to use virOject wrapper and keep reference
Patches 3~7: switch existing qemu and lxc driver to use virHostdevManager's
lists, so that to maintain a global state of every host device.
Patches 8~45 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 v13:
* change virHostdevManager, use virObject and keep reference, solve 'free'
problem
* add .hostdevMgr to qemu/lxc/libxl driver, get virHostdevManager in
StateInitialize for once and keep reference, instead of getting it every
time virHostdevManager is used.
* fix v13 3/49 "qemu-reuse-hostdev-interfaces-to-avoid-duplicate.patch":
update qemuPrepareHostUSBDevices parameters to specify hostdevs and
nhostdevs, so that could be reused in qemu_hotplug.
* rebase left patches
