[libvirt] [PATCH v2 00/10] Remove caching of address sets

[Tomasz Flendrich]

From: Tomasz Flendrich <Darge at users.noreply.github.com>

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.

I know that USB addresses were added and that they are cached now. I am sure
that they can be calculated on demand too though.

If this gets accepted, I will rebase the other patches that depend on this one,
making functions less dependant on qemu, and removing the code duplication.

Changes in v2:
* I rebased it, because there were some changes that added a usb address set.
* virDomainReleaseDeviceAddress is no longer deleted, because it's used
  for usb addresses. It also means that in qemu_hotplug.c, this function's
  calls are not deleted anymore.
* In qemu_hotplug.c, in one place, virDomainPCIAddressSetFree() was previously
  called after the "error:" label. I moved it to the "cleanup:", so the address
  set is freed even if an error occurs.
* Add one missing free of pci address set, in qemuDomainAttachNetDevice().
