d3c784999d conf: Add support of zero-detection for disks
This option allows or disallows detection of zero-writes if it is set to
"on" or "off", respectively.  It can be also set to "unmap" in which
case it will try discarding that part of image based on the value of the
"discard" option.

acc83afe33 vnc: add support for listen type 'socket'
VNC graphics already supports sockets but only via 'socket' attribute.
This patch coverts that attribute into listen type 'socket'.

For backward compatibility we need to handle listen type 'socket' and 'socket'
attribute properly to support old XMLs and new XMLs.  If both are provided they
have to match, if only one of them is provided we need to be able to parse that
configuration too.

To not break migration back to old libvirt if the socket is provided by user we
need to generate migratable XML without the listen element and use only 'socket'
attribute.

4d100c7a41 conf: permit auto-assignment of controller indexes
Hand-entering indexes for 20 PCI controllers is not as tedious as
manually determining and entering their PCI addresses, but it's still
annoying, and the algorithm for determining the proper index is
incredibly simple (in all cases except one) - just pick the lowest
unused index.

The one exception is USB2 controllers because multiple controllers in
the same group have the same index. For these we look to see if 1) the
most recently added USB controller is also a USB2 controller, and 2)
the group *that* controller belongs to doesn't yet have a controller
of the exact model we're just now adding - if both are true, the new
controller gets the same index, but in all other cases we just assign
the lowest unused index.

With this patch in place and combined with the automatic PCI address
assignment, we can define a PCIe switch with several ports like this:

  <controller type='pci' model='pcie-root-port'/>
  <controller type='pci' model='pcie-switch-upstream-port'/>
  <controller type='pci' model='pcie-switch-downstream-port'/>
  <controller type='pci' model='pcie-switch-downstream-port'/>
  <controller type='pci' model='pcie-switch-downstream-port'/>
  <controller type='pci' model='pcie-switch-downstream-port'/>
  <controller type='pci' model='pcie-switch-downstream-port'/>
  ...

These will each get a unique index, and PCI addresses that connect
them together appropriately with no pesky numbers required.

c026f8f1c2 qemu: auto-assign addresses when <address type='pci'/> is specified
Rather than only assigning a PCI address when no address is given at
all, also do it when the config says that the address type is 'pci',
but it gives no address (virDeviceInfoPCIAddressWanted()).

There are also several places after parsing but prior to address
assignment where code previously expected that any info with address
type='pci' would have a *valid* PCI address, which isn't always the
case - now we check not only for type='pci', but also for a valid
address (virDeviceInfoPCIAddressPresent()).

The test case added in this patch was directly copied from Cole's patch titled:

55320c23dd qemu: Regenerate VNC socket paths
Similarly to what commit 7140807917 did with some internal paths,
clear vnc socket paths that were generated by us.  Having such path in
the definition can cause trouble when restoring the domain.  The path is
generated to the per-domain directory that contains the domain ID.
However, that ID will be different upon restoration, so qemu won't be
able to create that socket because the directory will not be prepared.

To be able to migrate to older libvirt, skip formatting the socket path
in migratable XML if it was autogenerated.  And mark it as autogenerated
if it already exists and we're parsing live XML.

Best viewed with '-C'.

bc07251f59 conf: new pci controller model pcie-expander-bus
This controller provides a single PCIe port on a new root. It is
similar to pci-expander-bus, intended to provide a bus that can be
associated with a guest-identifiable NUMA node, but is for
machinetypes with PCIe rather than PCI (e.g. q35-based machinetypes).

Aside from PCIe vs. PCI, the other main difference is that a
pci-expander-bus has a companion pci-bridge that is automatically
attached along with it, but pcie-expander-bus has only a single port,
and that port will only connect to a pcie-root-port, or to a
pcie-switch-upstream-port. In order for the bus to be of any use in
the guest, it must have either a pcie-root-port or a
pcie-switch-upstream-port attached (and one or more
pcie-switch-downstream-ports attached to the
pcie-switch-upstream-port).

52f3d0a4d2 conf: new pci controller model pci-expander-bus
This is a standard PCI root bus (not a bridge) that can be added to a
440fx-based domain. Although it uses a PCI slot, this is *not* how it
is connected into the PCI bus hierarchy, but is only used for
control. Each pci-expander-bus provides 32 slots (0-31) that can
accept hotplug of standard PCI devices.

The usefulness of pci-expander-bus relative to a pci-bridge is that
the NUMA node of the bus can be specified with the <node> subelement
of <target>. This gives guest-side visibility to the NUMA node of
attached devices (presuming that management apps only assign a device
to a bus that has a NUMA node number matching the node number of the
device on the host).

Each pci-expander-bus also has a "busNr" attribute. The expander-bus
itself will take the busNr specified, and all buses that are connected
to this bus (including the pci-bridge that is automatically added to
any expander bus of model "pxb" (see the next commit)) will use
busNr+1, busNr+2, etc, and the pci-root (or the expander-bus with next
lower busNr) will use bus numbers lower than busNr.

a89f05ba8d qemu: Shorten per-domain directory names
Per-domain directories were introduced in order to be able to
completely separate security labels for each domain (commit
f1f68ca334).  However when the domain
name is long (let's say a ridiculous 110 characters), we cannot
connect to the monitor socket because on length of UNIX socket address
is limited.  In order to get around this, let's shorten it in similar
fashion and in order to avoid conflicts, throw in an ID there as well.
Also save that into the status XML and load the old status XMLs
properly (to clean up after older domains).  That way we can change it
in the future.

The shortening can be seen in qemuxml2argv tests, for example in the
hugepages-pages2 case.

c1c4d0d5a5 tests: qemuxml2xml: assign device addresses
We use the PreFormat callback for this. Many test cases need to be extended
to pass in proper qemuCaps flags so AssignAddresses doesn't throw errors.

One test case (pcie-root-port-too-many) is dropped, since it was meant
only for checking an error condition in qemuxml2argv, and one we add in
AssignAddresses it errors here too.

Long term I think AssignAddresses should be handled in qemu's PostParse
callback, but that's not entirely straightforward. Handling it here
means we can get the test suite churn over with.

d093d623e3 tests: qemuxml2xml: Always use different output file
Most qemuxml2xml tests expect that the input XML is unchanged after
parsing. This is unlike 99% of new qemu configs in the wild, which after
initial parsing end up with stable PCI device addresses. The xml2xml bit
doesn't currently hit that code path though, so most XML testing indeed
does not change.

Future patches will add that PCI address bits, which means most test cases
will have different output. So let's do away with the hardcoded same vs
different test split, and always track a separate output file. Tests can
still have same input and output, it just necessitates 2 separate XML files.
