d3f3c2c97f domain_conf.c: auto-align pSeries NVDIMM in virDomainMemoryDefPostParse()
The alignment for the pSeries NVDIMM does not depend on runtime
constraints. This means that it can be done in device parse
time, instead of runtime, allowing the domain XML to reflect
what the auto-alignment would do when the domain starts.

This brings consistency between the NVDIMM size reported by the
domain XML and what the guest sees, without impacting existing
guests that are using an unaligned size - they'll work as usual,
but the domain XML will be updated with the actual size of the
NVDIMM.

ace5931553 conf, qemu: move qemuDomainNVDimmAlignSizePseries to domain_conf.c
We'll use the auto-alignment function during parse time, in
domain_conf.c. Let's move the function to that file, renaming
it to virDomainNVDimmAlignSizePseries(). This will also make it
clearer that, although QEMU is the only driver that currently
supports it, pSeries NVDIMM restrictions aren't tied to QEMU.

d202681781 virnetdaemon: fix memory leak in virNetDaemonCallInhibit
g_variant_new() returns a weak reference which can be consumed by passing
to other g_variant* functions or to g_dbus_connection_call* functions.

This make it possible to call g_variant_new() directly as argument to
the functions above. Because this might be confusing I explicitly call
g_variant_ref_sink() to make it normal reference in both
virGDBusCallMethod() and virGDBusCallMethodWithFD() so the caller is
always responsible for the data.

63af8fdeb2 qemu: revert latest pSeries NVDIMM design changes
In [1], changes were made to remove the existing auto-alignment
for pSeries NVDIMM devices. That design promotes strange situations
where the NVDIMM size reported in the domain XML is different
from what QEMU is actually using. We removed the auto-alignment
and relied on standard size validation.

However, this goes against Libvirt design philosophy of not
tampering with existing guest behavior, as pointed out by Daniel
in [2]. Since we can't know for sure whether there are guests that
are relying on the auto-alignment feature to work, the changes
made in [1] are a direct violation of this rule.

This patch reverts [1] entirely, re-enabling auto-alignment for
pSeries NVDIMM as it was before. Changes will be made to ease
the limitations of this design without hurting existing
guests.

This reverts the following commits:

- commit 2d93cbdea9
  Revert "formatdomain.html.in: mention pSeries NVDIMM 'align down' mechanic"

- commit 0ee56369c8
  qemu_domain.c: change qemuDomainMemoryDeviceAlignSize() return type

4277e61e22 bhyve: soften requirements for slot 1
Currently, slot 1 is only allowed to be used by the LPC device.
Relax this requirement and allow to use slot 1 if it was explicitly
specified by the user for any other device type. In this case the LPC
device will have the next available address.

If slot 1 was not used by the user, it'll be reserved for the LPC
device, even if it is not configured to make address assignment
consistent in case the LPC device becomes necessary (e.g. the user
adds a console or a video device which require LPC).

16a2882350 bhyve: support 'isa' controller for LPC
Support modeling of the 'isa' controller for bhyve. User can manually
define any PCI slot for the 'isa' controller, including PCI slot 1,
but other devices are not allowed to use this address.

When domain configuration requires the 'isa' controller to be present,
automatically add it on domain post-parse stage.

Now, as this controller is always available when needed, it's not
necessary to implicitly add it to the bhyve command line, so remove
bhyveBuildLPCArgStr().

Also, make bhyveDomainDefNeedsISAController() static as it's no longer
used outside of bhyve_domain.c.

As more than one ISA controller is not supported by bhyve,
and multiple controllers with the same index are forbidden,
so forbid ISA controllers with non-zero index for bhyve.

2ef84f000f util: introduce helpers for GLib DBus implementation
With libdbus our wrappers had a special syntax to create the DBus
messages by defining the DBus message signature followed by list
of arguments providing data based on the signature.

There will be no similar helper with GLib implementation as they
provide same functionality via GVariant APIs. The syntax is slightly
different mostly for how arrays, variadic types and dictionaries are
created/parsed.

Additional difference is that with GLib DBus everything is wrapped in
extra tuple (struct). For more details refer to the documentation [1].

de3289e2b5 remove HAL node device driver
There was one attempt a year ago done by me to drop HAL [1] but it was
never resolved. There was another time when Dan suggested to drop HAL
driver [2] but it was decided to keep it around in case device
assignment will be implemented for FreeBSD and the fact that
virt-manager uses node device driver [3].

I checked git history and code and it doesn't look like bhyve supports
device assignment so from that POV it should not block removing HAL.

The argument about virt-manager is not strong as well because libvirt
installed from FreeBSD packages doesn't have HAL support so it will not
affect these users as well [4].

The only users affected by this change would be the ones compiling
libvirt from GIT on FreeBSD.

I looked into alternatives and there is libudev-devd package on FreeBSD
but unfortunately it doesn't work as it doesn't list any devices when
used with libvirt. It provides libudev APIs using devd.

I also looked into devd directly and it provides some APIs but there are
no APIs for device monitoring and events so that would have to be
somehow done by libvirt.

Main motivation for dropping HAL support is to replace libdbus with GLib
dbus implementation and it cannot be done with HAL driver present in
libvirt because HAL APIs heavily depends on symbols provided by libdbus.

5756a7bf2a qemu: fix concurrency crash bug in force snapshot revert
This patch is just revert of [1]. Actually we should NOT pass
QEMU_ASYNC_JOB_NONE as that patch suggests while we are in async job in order
to acquire nested jobs correctly. The patch tries to fix issues introduced by
another patch [2] where jobs are mistakenly cleared out in qemuProcessStop.
Later patch [3] fixed the issue introduced by patch [2]. Now we need to revert
[1] as well as we now still have same concurrency crash issues as [3] described
but for the force revert.

The 'readonly' hostdev property is stored separately from the
virStorageSource as some hostdevs are not described by a virStorage
source. We need to propagate the flag to the virStorage source also for
iSCSI backends as it's used to generate the backend properties.

1a5f35dbd2 qemu: backup: Write TLS cert and secret object aliases into status XML
We've put the aliases into the backup job definition after the status
XML was already written so they didn't appear in the on-disk state.

Move the code putting them into the private definition earlier, so that
the status XML update done by saving blockjobs already writes them out.

Also add a note notifying that the block job status update writes the
status XML.
