These patches delete the caching of pci, virtioSerial and ccw address sets.
I am deleting them, because they can be recalculated from the domain definition,
and there's no point in keeping redundant data, especially because handling
a persistent cache of addresses required using functions that released addresses.
These functions aren't useful anymore, so they are dropped too.

New subject: [libvirt] [PATCH 01/10] add virDomainVirtioSerialAddrSetCreateFromDomain
The address sets (pci, ccw, virtio serial) are currently cached
in qemu private data, but all the information required to recreate
these sets is in the domain definition. Therefore I am removing
the redundant data and adding a way to recalculate these sets.
Add a function that calculates the virtio serial address set
from the domain definition.
Credit goes to Cole Robinson.

The address sets (pci, ccw, virtio serial) are currently cached
in qemu private data, but all the information required to recreate
these sets is in the domain definition. Therefore I am removing
the redundant data and adding a way to recalculate these sets.
Add a function that calculates the pci address set from
the domain definition.
The part of pci address assignment that is not a dryRun is
separated from qemuDomainAssignPCIAddresses into a new function:
qemuDomainPCIAddrSetCreateFromDomain. The first time this function
is run, it can allocate some new addresses. After all the pci
addresses are assigned, on subsequent runs to this function, it just
recreates the pci address set.

New subject: [libvirt] [PATCH 08/10] qemu_hotplug: generate pci address list on demand
Dropping the caching of pci address set.
Instead of using the cached address set, functions in qemu_hotplug.c
now recalculate it on demand.
