Peter Krempa c225398015 qemu: Always assume support for QEMU_CAPS_PIIX_DISABLE_S* and QEMU_CAPS_ICH9_DISABLE_S*
The support for PIIX power management was added in qemu commit
v1.0-3094-g459ae5ea5a and the suport for ICH9 power management was added
in qemu commit v2.2.0-542-g6ac0d8d44c and both can't be compiled out.

This means we can always assume support for these features. Remove the
validation and impossible tests. Move relevant bits from
'q35-pm-disable' to 'q35' test case.

Martin Kletzander e95b81c2fd conf: Generate MAC address instead of keeping all zeroes
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.

Michal Privoznik ead76d2ac7 syntax-check: Introduce a rule for one line error messages
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

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).
