For network devices allocated from a network with <forward
mode='hostdev'>, there is a need to add the newly minted hostdev to
the hostdevs array.
In this case we also need to call qemuPrepareHostDevices just for this
one device, as the standard call to initialize all the hostdevs that
were defined directly in the domain's configuration has already been
made by the time we allocate a device from a libvirt network, and thus
have something that needs initializing.

This patch updates the network driver to properly utilize the new
attributes/elements that are now in virNetworkDef

This function is needed by the network driver in a later commit.
It is useful in functions like networkNotifyActualDevice and
networkReleaseActualDevice
The network pool should be able to keep track of both network device
names and PCI addresses, and return the appropriate one in the
actualDevice when networkAllocateActualDevice is called.

This patch introduces the new forward mode='hostdev' along with
attribute managed. Includes updates to the network RNG and new xml
parser/formatter code.

Existing code that creates a list of forwardIfs from a single PF
was moved to the new utility function networkCreateInterfacePool.
No functional change.

Move the functions the parse/format, and validate PCI addresses to
their own file so they can be conveniently used in other places
besides device_conf.c
Refactoring existing code without causing any functional changes to
prepare for new code.
This patch makes the code reusable.

If a system has 64 or more VF's, it is quite tedious to mention each VF
in the interface pool.
The following modification will implicitly create an interface pool from
the SR-IOV PF.
This functions enables us to get the Virtual Functions attached to
a Physical function given the name of a SR-IOV physical functio.
In order to accomplish the task, added a getter function pciGetDeviceAddrString
to get the BDF of the Virtual Function in a char array.
pciDeviceListSteal(pcidevs, dev) removes dev from pcidevs reducing
the length of pcidevs, so moving onto what was the next dev is wrong.
Instead callers should pop entry 0 repeatedly until pcidevs is empty.
