Add a test to demonstrate the effect of automatic virtio-serial
address assignment.

The 7c3c7f21 and f5c2d6 commits introduced a nodeinfo test.
In order to do that, some parts of sysfs had to be copied.
However, sysfs is full of symlinks, so during copying some
symlinks broke. Remove them, as on different systems they can
point to different files or be broken. At the same time, we don't
need all files added in those commits. For instance we don't care
about 'uevent' files, 'power' folders, and others.

QEMU 2.3 adds these new models to cover Haswell and Broadwell CPUs with
updated microcode. Luckily, they also reverted former the machine type
specific changes to existing models. And since these changes were never
released, we don't need to hack around them in libvirt.

Recently we've fixed a bug where the status XML could not be parsed as
the parser used absolute path XPath queries. This test enhancement tests
all XML files used in the qemu-xml-2-xml test as a part of a status XML
snippet to see whether they are parsed correctly. The status XML-2-XML is
currently tested in 223 cases with this patch.

The current auto-indentation buffer code applies indentation only on
complete strings. To allow adding a string containing newlines and
having it properly indented this patch adds virBufferAddStr.

To allow adding more tests, refactor the XML-2-XML test so that the
files are not reloaded always and clarify the control flow.

Result of this changes is that the active and inactive portions of the
XML are tested in separate steps rather than one test step.

Function virQEMUCapsInitGuestFromBinary detect kvm support by testing
whether /dev/kvm exists or whether we pass path to kvmbin.  Provide the
path we are testing via kvmbin for testing purpose instead of detecting

Add support to start qemu instance with 'pc-dimm' device. Thanks to the
refactors we are able to reuse the existing function to determine the
parameters.

This patch adds code that parses and formats configuration for memory
devices.

A simple configuration would be:
<memory model='dimm'>
  <target>
    <size unit='KiB'>524287</size>
    <node>0</node>
  </target>
</memory>

A complete configuration of a memory device:
<memory model='dimm'>
  <source>
    <pagesize unit='KiB'>4096</pagesize>
    <nodemask>1-3</nodemask>
  </source>
  <target>
    <size unit='KiB'>524287</size>
    <node>1</node>
  </target>
</memory>

This patch preemptively forbids use of the <memory> device in individual
drivers so the users are warned right away that the device is not
supported.

To enable memory hotplug the maximum memory size and slot count need to
be specified. As qemu supports now other units than mebibytes when
specifying memory, use the new interface in this case.

Add a XML element that will allow to specify maximum supportable memory
and the count of memory slots to use with memory hotplug.

To avoid possible confusion and misuse of the new element this patch
also explicitly forbids the use of the maxMemory setting in individual
drivers's post parse callbacks. This limitation will be lifted when the
support is implemented.

Lets not give a bad example and check for return values of
virNetwork* APIs called within the test. Even though it's
unlikely that any API will fail, it can happen. We're connected
to the test driver after all, and our API sequence is correct. So
test driver should fail only in case of bug or OOM.

Midonet is an opensource virtual networking that over lays the IP
network between hypervisors. Currently, such networks can be made
with the openvswitch virtualport type.

This patch, defines the schema and documentation that will serve
as basis for the follow up patches that will add support to libvirt
for using Midonet virtual ports for its interfaces. The schema
definition requires that the port profile expresses its interfaceid
as part of the port profile. For that reason, this is part of the
patch too.

By querying the qemu guest agent with the QMP command
"guest-network-get-interfaces" and converting the received JSON
output to structured objects.

Although "ifconfig" is deprecated, IP aliases created by "ifconfig"
are supported by this API. The legacy syntax of an IP alias is:
"<ifname>:<alias-name>". Since we want all aliases to be clubbed
under parent interface, simply stripping ":<alias-name>" suffices.
Note that IP aliases formed by "ip" aren't visible to "ifconfig",
and aliases created by "ip" do not have any specific name. But
we are lucky, as qemu guest agent detects aliases created by both.

Now that the size of guest's memory can be inferred from the NUMA
configuration (if present) make it optional to specify <memory>
explicitly.

To make sure that memory is specified add a check that some form of
memory size was specified. One side effect of this change is that it is
no longer possible to specify 0KiB as memory size for the VM, but I
don't think it would be any useful to do so. (I can imagine embedded
systems without memory, just registers, but that's far from what libvirt
is usually doing).

Forbidding 0 memory for guests also fixes a few corner cases where 0 was
not interpreted correctly and caused failures. (Arguments for numad when
using automatic placement, size of the balloon). This fixes problems
described in https://bugzilla.redhat.com/show_bug.cgi?id=1161461

Test case changes are added to verify that the schema change and code
behave correctly.

Use the NUMA total instead of the configured size both in XML and for
uses in the code once NUMA is enabled for a domain.

One test case change is necessary as the rounding of the individual cell
sizes was not matching the rounding of the total size.

Use the new single function instead of calling
qemuMonitorJSONGetBlockStatsInfo and
qemuMonitorJSONGetBlockStatsParamsNumber. This will allow to delete the
functions later while still maintaining coverage.

Add a different version of parser for "info blockstats" that basically
parses the same information as the existing copy of the function.

This will allow us to remove the single device version
qemuMonitorGetBlockStatsInfo in the future.

The new implementation uses few new helpers so it should be more
understandable and provides a test case to verify that it works.

qemu HMP commands sent by libvirt are terminated just by a '\r'. The
fake monitor used in tests wasn't prepared to handle this and the
communication would hang on an attempt to do a HMP conversation.

Add a special case for handling commands separated by \r in case HMP is
used.

The error count statistic is not supported by qemu, so there's no need
to pass the variables around if the result is ignored anyways.

Our code supports that for ages. When using a <filterref/> to an
<interface/> several parameters can be passed to the filter. Later,
when building firewall rules, parameters are substituted for their
values. However, our RNG schema allowed only one parameter to be
passed.

We don't usually do tests purely for one change, but one change was
special because when users will migrate to OVMF/AAVMF, commit 18f9f69b
makes their lives easier by allowing them to interleave <type/> inside

the loader and nvram elements wherever it is valid, hence this test.
