Some test cases have the backend tag inside wrong interfaces. The backend xml
tag does not support <interface type='user|direct|hostdev'>. So this commit
changes some network types inside the interfaces that have backend defined.

This capability says if qemu is capable of specifying distances
between NUMA nodes on the command line. Unfortunately, there's no
real way to check this and thus we have to go with version check.

released in 2.10.0.

There's no point in checking if numa->mem_nodes[node].ndistances

When QEMU dies, we read its output stored in a log file and use it for
reporting a hopefully useful error. However, virReportError will trim
the message to (VIR_ERROR_MAX_LENGTH - 1) characters, which means the
end of the log (which likely contains the error message we want to
report) may get lost. We should trim the beginning of the log instead.

Still because of commit id 'fe8f1c8b' where we generate a REF for the
Register and that's transparent to the consumer (e.g. how would they
know they need to ensure that Deregister is called), thus the purpose of
this patch is to find a way to Deregister if it's determined that the
consumer hasn't by the time of the "last" REF we'd have.

This solution to this problem is to alter the processing to have the
remoteClientCloseFunc handle performing the Deregister calls instead of
the remoteClientFreeFunc because there's no way FreeFunc would be called
unless the Deregister was already called.

Extract common clearing of event callbacks as remoteClientFreePrivateCallbacks.
the common function also separation including the sysident handling.

We have a check for backslash alignment that checks for two blanks preceding a
backslash.  However there can be alignment done using a tabulator and in some
cases one might be enough.  There are none currently, but I found out that was
the case before. at some point.  so let's check for \t preceding the final
backslash as well.

Explain that certain attributes formatted with -drive are in fact
attributes of the drive itself and not the storage backing it.

That's a disk frontend attribute. Move the code to a separate function
since it's non-trivial and call it from the frontend attribute
formatter.

Isolate it from the other code.

Move all logic depending on whether we are solely formatting -drive (no
-device along with it) into one block.

Move together sections which are conditionaly executed depending on
whether -device will be used together with the -drive.

Disk serial is not a property of the image but of the disk frontend.
Account for this appropriately.

Historically we've formatted a lot of the attributes of a disk (disk
geometry, etc) with -drive. Since we use -device now, they should be
formatted there. Extract them to a separate function for keeping
compatibility with SDcards which still use only -drive.

Start this by moving the geometry into a separate function.

When doing block commit we need to allow write for members of the
backing chain so that we can commit the data into them.

qemuDomainDiskChainElementPrepare was used for this which since commit
786d8d91 calls qemuDomainNamespaceSetupDisk which has very adverse
side-effects, namely it relabels the nodes to the same label it has in
the main namespace. This was messing up permissions for the commit
operation since its touching various parts of a single backing chain.

Since we are are actually not introducing new images at that point add a
flag for qemuDomainDiskChainElementPrepare which will refrain from
calling to the namespace setup function.

Calls from qemuDomainSnapshotCreateSingleDiskActive and
qemuDomainBlockCopyCommon do introduce new members all calls from
qemuDomainBlockCommit do not, so the calls are anotated accordingly.

Because WARN_CFLAGS and COVERAGE_CFLAGS are not set globally, we
rely on each binary built to include WARN_CFLAGS/COVERAGE_CFLAGS.
But it is easy to forget those - e.g. libvirt_shell.la. However,
don't enable WARN_FLAGS (i.e. don't include AM_CFLAGS) for
wireshark plugin - parts of that code are generated and trigger

This set of rules was proposed by Christian Boltz <apparmor@cboltz.de>
on https://bugzilla.opensuse.org/show_bug.cgi?id=1065123.

Current cleanup processing is ad-hoc at best - it's led to a couple of
strange and hard to diagnose timing problems and crashes.

So rather than perform cleanup in a somewhat random order, let's
perform cleanup in the exact opposite order of startup.

NB: It is possible that virNetlinkEventServerStart fails and we jump
to cleanup before driversInitialized has been set. That could leave
things inconsistent; however, resolution of that possibility is perhaps
more trouble than it's worth to handle.
