Move the alias name right after the object type for rng-egd backend so
that we can later use the JSON to commandline generator to create the
command line.

Libvirt didn't prefix the random number generator backend object alias
with any string thus the device alias and object alias were identical.

To avoid possible problems, rename the alias for the backend object and
tweak tests to comply with the change.

If a storage file would be backed with a NBD device without path
(nbd://localhost) libvirt would crash when parsing the backing path for
the disk as the URI structure's path element is NULL in such case but
the NBD parser would access it shamelessly.

I'm going to add a few test cases so it's the best time to convert the
test to automatic numbering.

Some code paths have special logic depending on the page size
reported by sysconf, which in turn affects the test results.
We must mock this so tests always have a consistent page size.

Change done by commit f309db1f wrongly
assumes that qemu can start with a combination of NUMA nodes specified
with the "memdev" option and the appropriate backends, and the legacy
way by specifying only "mem" as a size argument. QEMU rejects such
commandline though:

$ /usr/bin/qemu-system-x86_64 -S -M pc -m 1024 -smp 2 \
-numa node,nodeid=0,cpus=0,mem=256 \
-object memory-backend-ram,id=ram-node1,size=12345 \
-numa node,nodeid=1,cpus=1,memdev=ram-node1
qemu-system-x86_64: -numa node,nodeid=1,cpus=1,memdev=ram-node1: qemu: memdev option must be specified for either all or no nodes

To fix this issue we need to check if any of the nodes requires the new
definition with the backend and if so, then all other nodes have to use
it too.

QEMU's command line visitor as well as the JSON interface take bytes by
default for memory object sizes. Convert mebibytes to bytes so that we
can later refactor the existing code for hotplug purposes.

QEMU's qapi visitor code allows yes/on/y for true and no/off/n for false
value of boolean properities. Unify the used style so that we can
generate it later and fix test cases.

Move the alias as the second formated argument and tweak the tests so
that a future refactor that will change the order doesn't break tests.

Unlike -device, qemu uses a JSON object to add backend "objects" via the
monitor rather than the string that would be passed on the commandline.

To be able to reuse code parts that configure backends for various
devices, this patch adds a helper that will allow generating the command
line representations from the JSON property object.

Adding or reordering test cases is usually a pain due to static test
case names that are then passed to virtTestRun(). To ease the numbering
of test cases, this patch adds two simple helpers that generate the test
names according to the order they are run. The test name can be
configured via the reset function.

This will allow us to freely add test cases in middle of test groups
without the need to re-number the rest of test cases.

In one of our previous commits (dc8b7ce7) we've done a functional
change even though it was intended as pure refactor. The problem is,
that the following XML:

 <vcpu placement='static' current='2'>6</vcpu>
 <cputune>
   <emulatorpin cpuset='1-3'/>
 </cputune>
 <numatune>
   <memory mode='strict' placement='auto'/>
 </numatune>

gets translated into this one:

 <vcpu placement='auto' current='2'>6</vcpu>
 <cputune>
   <emulatorpin cpuset='1-3'/>
 </cputune>
 <numatune>
   <memory mode='strict' placement='auto'/>
 </numatune>

We should not change the vcpu placement mode. Moreover, we're doing
something similar in case of emulatorpin and iothreadpin. If they were
set, but vcpu placement was auto, we've mistakenly removed them from
the domain XML even though we are able to set them independently on
vcpus.

There are some interface types (notably 'server' and 'client')
which instead of allowing the default set of elements and
attributes (like the rest do), try to enumerate only the elements
they know of. This way it's, however, easy to miss something. For
instance, the <address/> element was not mentioned at all. This
resulted in a strange behavior: when such interface was added
into XML, the address was automatically generated by parsing
code. Later, the formatted XML hasn't passed the RNG schema. This
became more visible once we've turned on the XML validation on
domain XML changes: appending an empty line at the end of
formatted XML (to trick virsh think the XML had changed) made
libvirt to refuse the very same XML it formatted.

Instead of trying to find each element and attribute we are
missing in the schema, lets just allow all the elements and
attributes like we're doing that for the rest of types. It's no
harm if the schema is wider than our parser allows.

Well, even though users can pass the list of UEFI:NVRAM pairs at the
configure time, we may maintain the list of widely available UEFI
ourselves too. And as arm64 begin to rises, OVMF was ported there too.
With a slight name change - it's called AAVMF, with AAVMF_CODE.fd
being the UEFI firmware and AAVMF_VARS.fd being the NVRAM store file.

Up until now there are just two ways how to specify UEFI paths to
libvirt. The first one is editing qemu.conf, the other is editing
qemu_conf.c and recompile which is not that fancy. So, new
configure option is introduced: --with-loader-nvram which takes a
list of pairs of UEFI firmware and NVRAM store. This way, the
compiled in defaults can be passed during compile time without
need to change the code itself.

Record the index of each TAP device created and report them to
systemd, so they show up in machinectl status for the VM.

For stateless, client side drivers, it is never correct to
probe for secondary drivers. It is only ever appropriate to
use the secondary driver that is associated with the
hypervisor in question. As a result the ESX & HyperV drivers
have both been forced to do hacks where they register no-op
drivers for the ones they don't implement.

For stateful, server side drivers, we always just want to
use the same built-in shared driver. The exception is
virtualbox which is really a stateless driver and so wants
to use its own server side secondary drivers. To deal with
this virtualbox has to be built as 3 separate loadable
modules to allow registration to work in the right order.

This can all be simplified by introducing a new struct
recording the precise set of secondary drivers each
hypervisor driver wants

struct _virConnectDriver {
    virHypervisorDriverPtr hypervisorDriver;
    virInterfaceDriverPtr interfaceDriver;
    virNetworkDriverPtr networkDriver;
    virNodeDeviceDriverPtr nodeDeviceDriver;
    virNWFilterDriverPtr nwfilterDriver;
    virSecretDriverPtr secretDriver;
    virStorageDriverPtr storageDriver;
};

Instead of registering the hypervisor driver, we now
just register a virConnectDriver instead. This allows
us to remove all probing of secondary drivers. Once we
have chosen the primary driver, we immediately know the
correct secondary drivers to use.

Coverity reports that my commit af1c98e4 introduced
two memory leaks:
the cpumap if ncpus == 0 in virCgroupGetPercpuStats
and the params array in the test of the function.

My commit af1c98e4 broke the build on RHEL-6:
vircgrouptest.c: In function 'testCgroupGetPercpuStats':
vircgrouptest.c:566: error: nested extern declaration of
'_gl_verify_function2' [-Wnested-externs]

The only thing that needs checking is that the array size
is at least EXPECTED_NCPUS, to prevent access beyond the array.

We can ensure the minimum size also by specifying the array
size upfront.

Per-cpu stats are only shown for present CPUs in the cgroups,
but we were only parsing the largest CPU number from
/sys/devices/system/cpu/present and looking for stats even for
non-present CPUs.
This resulted in:
internal error: cpuacct parse error

The listen address is not mandatory for <interface type='server'>
but when it's not specified, we've been formatting it as:
-netdev socket,listen=(null):5558,id=hostnet0
which failed with:
Device 'socket' could not be initialized

Omit the address completely and only format the port in the listen
attribute.

Also fix the schema to allow specifying a model.

This adds a new "localOnly" attribute on the domain element of the
network xml.  With this set to "yes", DNS requests under that domain
will only be resolved by libvirt's dnsmasq, never forwarded upstream.

This was how it worked before commit f69a6b98, and I found that
functionality useful.  For example, I have my host's NetworkManager
dnsmasq configured to forward that domain to libvirt's dnsmasq, so I can
easily resolve guest names from outside.  But if libvirt's dnsmasq
doesn't know a name and forwards it to the host, I'd get an endless
forwarding loop.  Now I can set localOnly="yes" to prevent the loop.

The virDomainDefParse* and virDomainDefFormat* methods both
accept the VIR_DOMAIN_XML_* flags defined in the public API,
along with a set of other VIR_DOMAIN_XML_INTERNAL_* flags
defined in domain_conf.c.

This is seriously confusing & error prone for a number of
reasons:

 - VIR_DOMAIN_XML_SECURE, VIR_DOMAIN_XML_MIGRATABLE and
   VIR_DOMAIN_XML_UPDATE_CPU are only relevant for the
   formatting operation
 - Some of the VIR_DOMAIN_XML_INTERNAL_* flags only apply
   to parse or to format, but not both.

This patch cleanly separates out the flags. There are two
distint VIR_DOMAIN_DEF_PARSE_* and VIR_DOMAIN_DEF_FORMAT_*
flags that are used by the corresponding methods. The
VIR_DOMAIN_XML_* flags received via public API calls must
be converted to the VIR_DOMAIN_DEF_FORMAT_* flags where
needed.

The various calls to virDomainDefParse which hardcoded the
use of the VIR_DOMAIN_XML_INACTIVE flag change to use the
VIR_DOMAIN_DEF_PARSE_INACTIVE flag.

The virCPUDefFormat* methods were relying on the VIR_DOMAIN_XML_*
flag definitions. It is not desirable for low level internal
functions to be coupled to flags for the public API, since they
may need to be called from several different contexts where the
flags would not be appropriate.

QEMU supports feature specification with -cpu host and we just skip
using that.  Since QEMU developers themselves would like to use this
feature, this patch modifies the code to work.
