7db8373e08 Use G_N_ELEMENTS() more
In a few places we still use the good old:

  sizeof(var) / sizeof(var[0])
  sizeof(var) / sizeof(int)

The G_N_ELEMENTS() macro is preferred though. In a few places we
don't link with glib, so provide the macro definition.

a9a4421ba8 qemu: implement QEMU NBD source reconnect delay attribute
Currently it's only possible to set this parameter during domain
creation via QEMU commandline passthrough feature.
With the new delay attribute it's also possible to set this
parameter if you want to attach a new NBD disk
using "virsh attach-device domain device.xml" e.g.:

  <disk type='network' device='disk'>
    <driver name='qemu' type='raw'/>
    <source protocol='nbd' name='foo'>
      <host name='example.org' port='6000'/>
      <reconnect delay='10'/>
    </source>
    <target dev='vdb' bus='virtio'/>
  </disk>

97dddef48c qemuAppendLoadparmMachineParm: add loadparm from hostdev
Commit 54fa1b44af ("conf: Add loadparm boot option for a boot device")
added the ability to specify a loadparm parameter on a <boot/> tag, while
commit 29ba41c2d4 ("qemu: Add loadparm to qemu command line string")
added that value to the QEMU "-machine" command line parameters.

Unfortunately, the latter commit only looked at disks and network
devices for boot information, even though anything with
VIR_DOMAIN_DEF_FORMAT_ALLOW_BOOT could potentially have this tag.
In practice, a <hostdev> tag pointing to a passthrough (SCSI or DASD)
disk device can be used in this way, which means the loadparm is
accepted, but not given to QEMU.

Correct this, and add some XML/argv tests.

4ee4809907 qemu: validate: Fix logic for validating presence of the HPET timer
Commit 24cc9cda82 switched over to use -machine hpet, but one of the
steps it did was to clear the QEMU_CAPS_NO_HPET capability.

The validation check still uses the old capability though which means
that for configs which would explicitly enable HPET we'd report an error.

Since HPET is an x86(_64) platform specific device, convert the
validation check to an architecture check as all supported qemu versions
actually support it.

Modify a test case to request HPET to catch posible future problems.

2f56f69f7f tests: Create privileged config for QEMU driver
Our QEMU test suite effectively covers the qemu:///system

config with its privileged equivalent after the fact to keep up
the illusion.

Instead of jumping through these extra hoops, we can simply
start with a privileged configuration matching the privileged
driver we're creating for test programs.

This change highlights that we were missing a couple of
overrides, specifically in the tests for passt and dbus. Now
that we're creating a privileged config, this kind of issue
shouldn't be able to slip into the test suite.

98c4e3d073 qemu: Use '-machine acpi=on/off' instead of deprecated '-no-acpi'
QEMU deprecated the '-no-acpi' option, thus we should switch to the
modern way to use '-machine'.

Certain ARM machine types don't support ACPI. Given our historically
broken design of using '<acpi/>' without attribute to enable ACPI and
qemu's default of enabling it without '-no-acpi' such configurations
would not work.

Now when qemu reports whether given machine type supports ACPI we can do
a better decision and un-break those configs. Unfortunately not
retroactively.

9567f3ba1f qemu: Move firmware selection from startup to postparse
Currently, firmware selection is performed as part of the
domain startup process. This mostly works fine, but there's a
significant downside to this approach: since the process is
affected by factors outside of libvirt's control, specifically
the contents of the various JSON firmware descriptors and
their names, it's pretty much impossible to guarantee that the
outcome is always going to be the same. It would only take an
edk2 update, or a change made by the local admin, to render a
domain unbootable or downgrade its boot security.

To avoid this, move firmware selection to the postparse phase.
This way it will only be performed once, when the domain is
first defined; subsequent boots will not need to go through
the process again, as all the paths that were picked during
firmware selection are recorded in the domain XML.

Care is taken to ensure that existing domains are handled
correctly, even if their firmware configuration can't be
successfully resolved. Failure to complete the firmware
selection process is only considered fatal when defining a
new domain; in all other cases the error will be reported
during startup, as is already the case today.

ba5b338ee3 tests: Add descriptors for QCOW2 format firmware builds
Now that we ignore all firmwares that are not in raw format
while performing autoselection, we can have descriptors for
firmware builds in QCOW2 format without breaking anything.

Note that the descriptors are arranged so that they have the
highest priority on aarch64, but the lowest one on x86_64.
This matches the expectation that QCOW2 will quickly be
adopted as the default on aarch64, where its use produces
significant benefits in terms of memory usage, while x86_64
will likely stick with raw for the foreseeable future.

acd8333f76 qemu: add reconnect=5 to passt qemu commandline options when available
QEMU's "reconnect" option of "-netdev stream" tells QEMU to
periodically (period is given in seconds as an argument to the option)
attempt to reconnect to the same passt socket to which it had
originally connected to. This is useful in cases where the passt
process terminates, and libvirtd starts a new passt process in its
place (which doesn't happen yet, but will happen automatically after
an upcoming patch in this series).

Since there is no real hueristic for determining the "best" value of
the reconnect interval, rather than clutter up config with a knob that
nobody knows how to properly twiddle, we just set the reconnect timer
to 5 seconds.

"-netdev stream" first appeared in QEMU 7.2.0, but the reconnect
option won't be available until QEMU 8.0.0, so we need to check QEMU
capabilities just in case someone is using QEMU 7.2.0 (and thus can
support passt backend, but not reconnect)
