Add QMP schema data query for aarch64. The gic capabilities are
unfortunately queried after the QMP schema and thus this patch needs to
undo the temporary removal of the declared support for query-qmp-schema.
Note that as a gicv3 machine was not available the schema data is taken
from the gicv2 case. It should be identical since qemu would be built
from the same source.

Allow detecting capabilities according to the qemu QMP schema. This is
necessary as sometimes the availability of certain options depends on
the presence of a field in the schema.
This patch adds support for loading the QMP schema when detecting qemu
capabilities and adds a very simple query language to allow traversing
the schema and selecting a certain element from it.
The infrastructure in this patch uses a query path to set a specific
capability flag according to the availability of the given element in
the schema.
Remove the command from the supported commands list temporarily so that
QMP introspection code can be added without breaking tests and having to
tweak the test data in the same commit.
This will be later reverted and test data will be added. The aarch64
code is special as it calls additional commands and thus the test data
can't be added upfront.
Some operations like reboot, save, coreDump, blockStats,
ifaceStats make sense iff domain is running. While it is
technically possible for our test driver to return success
regardless of domain state, we should copy constraints from
other drivers and thus deny these operations over inactive
domains.

Add check in qemuCheckDiskConfig for an invalid combination
of using the 'scsi' bus for a block 'lun' device and any disk
source format other than 'raw'.
Fixes the behavior when destroying a domain more than once.
VIR_ERR_OPERATION_INVALID should be raised when destroying an

Release tarballs ship the include/libvirt/libvirt-common.h.
when srcdir != builddir we end up including libvirt-common.h twice: from
$top_srcdir/include/libvirt-common.h and from
$builddir/include/libvirt-common.h leading to
function virTypedParamsGetUInt from /tmp/buildd/libvirt-2.4.0/debian/build/docs/../include/libvirt/libvirt-common.h redeclared in /tmp/buildd/libvirt-2.4.0/docs/../include/libvirt/libvirt-common.h

…
Only add the builddir to the search list if there is no pregenerated
libvirt-common.h.
Reuse the existing check that predates the libvirt.h → libvirt-common.h
split and that probably was meant for exactly that.

Commit e8861f6971 changed our spec file to compile and run
tests in parallel. That's a very good step forward, but why
stop there? Let's run *all* make jobs in parallel and really
put those expensive cores to use!
On my laptop, this shaves ~10s off 'make rpm'.
${exec_prefix} and ${prefix} point to the same directory in
most setups, but when that's not the case the former should
be used for architecture-dependent data such as shared objects,
which makes it the best fit for our Wireshark dissector.
While at it, change all uses of $(var) to ${var}: they are
absolutely identicaly as far as make's concerned, but autoconf
itself seems to prefer the latter form so we might as well
follow suit.
We only need to strip $ws_prefix from $ws_plugindir if we've
retrieved it from pkg-config: if we're building it ourselves
from $libdir, we can just use it without further processing.

Let's keep all run time validation of cached QEMU capabilities in

virQEMUCapsInitCached should keep only the checks which do not make
sense once the cache is loaded in memory.

So far, the main code is built in parallel, which makes it pretty
fast. But with a lots of tests we have now I've noticed this part
takes too much time to build. The problem was that tests were
build and run in a single job.
Also, 'make' in the first hunk is useless. The test suite is not
built due to 'make all' because there's no .git in the sources
unpacked from a tar.xz archive. It's 'make check' which triggers
tests build.

QEMU added support for ivshmem-plain and ivshmem-doorbell. Those are
reworked varians of legacy ivshmem that are compatible from the guest
POV, but not from host's POV and have sane specification and handling.
Details about the newer device type can be found in qemu's commit
5400c02b90bb:

We're keeping some things at default and that's not something we want to
do intentionally. Let's save some sensible defaults upfront in order to
avoid having problems later. The details for the defaults (of the newer
implementation) can be found in qemu's commit 5400c02b90bb:
http://git.qemu.org/?p=qemu.git;a=commit;h=5400c02b90bb
Since we are merely saving the defaults it will not change the guest ABI
and thanks to the fact that we're doing it in the PostParse callback it
will not break the ABI stability checks.

Unlike other migration capabilities, post-copy is also set on the
destination host which means it doesn't disappear once domain is
migrated. As a result of that other functionality which internally uses
migration to a file (virDomainManagedSave, virDomainSave,
virDomainCoreDump) may fail after migration because the post-copy
capability is still set.

The library.xen file contains a braindump of thoughts dating

Commit id 'dcfdf341' passes 'opts_need_arg' and 'opts_seen' to
vshCmddefGetData, but that seems to be incorrect as those values
are not initialized properly (something at least one compiler found).
Instead the static 'const_opts_need_arg' and 'const_opts_seen' values
should be passed.
By passing unitialized values leads to not finding possible options
for simpler commands (domfsfreeze for example), where if you're in
a virsh shell using command line completion - you'll get a list of
files in your current directory instead of two options --domain and
--mountpoint (as would happen with this patch applied.

commit 9065cfaa added the ability to disable DNS services for a
libvirt virtual network. If neither DNS nor DHCP is needed for a
network, then we don't need to start dnsmasq, so code was added to
check for this.
Unfortunately, it was written with a great lack of attention to detail
(I can say that, because I was the author), and the loop that checked
if DHCP is needed for the network would never end if the network had
multiple IP addresses and the first <ip> had no <dhcp> subelement
(which would have contained a <range> or <host> subelement, thus
requiring DHCP services).
This patch rewrites the check to be more compact and (more
importantly) finite.
This bug was present in release 2.2.0 and 2.3.0, so will need to be
backported to any relevant maintainence branches.
