The @niothreads inside of virCHMonitorGetIOThreads() is declared
as of size_t type. This would work, except the variable is then
passed to VIR_DEBUG with incorrect format directive (%ld) and
returned. But the function returns an int not size_t. Fix the

When we parse <mac address="00:00:00:00:00:00"/> we keep that in memory
and pass it down to the hypervisor. However, that MAC address is not
strictly valid as it is not marked as locally administered (bit 0x02)
but it is not even globally unique. It is also used for loopback device
on Linux, for example. And QEMU sees such MAC address just as "not
specified" and generates a new one that libvirt does not even know
about. So to make the overall experience better we now generate it if
the supplied one is all clear.

Meson doesn't interpret what's set in CFLAGS, but rather simply appeds

Okay, this is a shortcut. Our coding style says that error
messages are exempt from '80 chars long lines' rule. But in the
very same paragraph it is said that all error messages need to be
marked for translation (as they might be presented to user).
Therefore, the syntax-check rule can check if _("...") is
formatted on one line. With exception of _("...\n" ...) (e.g.
various outputs from helper binaries like leaseshelper,
sshhelper, or daemons like lockd, logd). I believe nobody would
chose a substring that contains '\n' for git grep-ping the error
message.

The --help output of virsh and virt-admin shows supported options
and commands and as such contains new lines. Both these strings
are marked for translation btw. But the way they are formatted
now ('\n' being at the start of new line instead at the end of
the previous) makes it hard to create a syntax-check rule for
'translation message on one line' (next commit).
Reformat both strings a bit (no user visible change though).
