Rewrite to use GLib DBus instead of libdbus will introduce function with
large number of arguments that we will have to mock for our tests so we
need to extend the number of arguments for our macros.

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].

This test calls into src/util/virfirewalld.c where it uses DBus to
figure out if firewalld is registered. Without the mock it luckily
fails and the test works correctly.
To isolate the tests from host environment we should mock the DBus
calls.

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.

Move the code putting them into the private definition earlier, so that

QEMU's blockdev nodenames which are used to back SCSI/iSCSI hostdevs are
limited to 32 characters. If a user passes a very long user alias as
name of the host device it's easy to end up with a too-long nodename.
To prevent this from happening don't base the nodename on the possibly
user-specified alias but on the normal sequential node name generator.
We then store the name in the status XML for further use.
