Subject: [PATCH] Add host PCI device hotplug support
Attaching a host PCI device to a qemu guest is done with a
straightforward 'pci_add pci_addr auto host host=XX:XX.X' command.
Like with NIC and disk hotplug, we need to retain the guest PCI address
assigned by qemu so that we can use it for hot-unplug.
Identifying a device for detach is done using the host PCI address.
Managed mode is handled by detaching/resetting the device before
attaching it to the guest and re-attaching it after detaching it from
the guest.

Subject: [PATCH] Maintain a list of active PCI hostdevs and use it in pciResetDevice()
https://bugzilla.redhat.com/499678
First we add a pciDeviceList type and add a qemuGetPciHostDeviceList()
function to build a list from a domain definition. Use this in
prepare/re-attach to simplify things and eliminate the multiple
pciGetDevice() calls.
Then, as we start/shutdown guests we can add or delete devices as
appropriate from a list of active devices.
Finally, in pciReset(), we can use this to determine whether its safe to
reset a device as a side effect of resetting another device.

Subject: [PATCH] Allow PM reset on multi-function PCI devices
https://bugzilla.redhat.com/515689
It turns out that a PCI Power Management reset only affects individual
functions, and not the whole device.
The PCI Power Management spec talks about resetting the 'device' rather
than the 'function', but Intel's Dexuan Cui informs me that it is
actually a per-function reset.
Also, Yu Zhao has added pci_pm_reset() to the kernel, and it doesn't
reject multi-function devices, so it must be true! :-)
(A side issue is that we could defer the PM reset to the kernel if we
could detect that the kernel has PM reset support, but barring version
number checks we don't have a way to detect that support)
* src/pci.c: remove the pciDeviceContainsOtherFunctions() check from
pciTryPowerManagementReset() and prefer PM reset over bus reset
where both are available

Subject: [PATCH] Improve PCI host device reset error message
https://bugzilla.redhat.com/499678
Currently, if we are unable to reset a PCI device we return a fairly
generic 'No PCI reset capability available' error message.
Fix that by returning an error from the individual reset messages and
using that error to construct the higher level error mesage.
* src/pci.c: set errors in pciTryPowerManagementReset() and
pciTrySecondaryBusReset() on failure; use those error messages
in pciResetDevice(), or explain that no reset support is available

Subject: [PATCH] Reset and re-attach PCI host devices on guest shutdown
https://bugzilla.redhat.com/499561
When the guest shuts down, we should attempt to restore all PCI host
devices to a sane state.
In the case of managed hostdevs, we should reset and re-attach the
devices. In the case of unmanaged hostdevs, we should just reset them.
Note, KVM will already reset assigned devices when the guest shuts
down using whatever means it can, so we are only doing it to cover the
cases the kernel can't handle.
* src/qemu_driver.c: add qemuDomainReAttachHostDevices() and call
it from qemudShutdownVMDaemon()
