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.

QEMU could put in a bigger value and will be bothered with validation

This patch introduces the
<maxphysaddr mode='passthrough'/>
<maxphysaddr mode='emulate' bits='42'/>
sub element of /domain/cpu, which allows specifying the guest virtual CPU
address size. This can be useful if the guest needs to have a large amount
of memory.
If mode='passthrough', the virtual CPU will have the same number of address
bits as the host. If mode='emulate', the mandatory bits attribute specifies
the number of address bits.

This is only used in the ESX driver where, when set to "no", it will
ignore all the checks libvirt does about the origin of the MAC address
(whether or not it's in a VMWare OUI) and forward the original one to
the ESX server telling it not to check it either.
This allows keeping a deterministic MAC address which can be useful for
licensed software which might dislike changes.

The launch-security element can be used to define the security
model to use when launching a domain. Currently we support 'sev'.
When 'sev' is used, the VM will be launched with AMD SEV feature enabled.
SEV feature supports running encrypted VM under the control of KVM.
Encrypted VMs have their pages (code and data) secured such that only the
guest itself has access to the unencrypted version. Each encrypted VM is
associated with a unique encryption key; if its data is accessed to a
different entity using a different key the encrypted guests data will be
incorrectly decrypted, leading to unintelligible data.

TSEG (Top of Memory Segment) is one of many regions that SMM (System Management
Mode) can occupy. This one, however is special, because a) most of the SMM code
lives in TSEG nowadays and b) QEMU just (well, some time ago) added support for
so called 'extended' TSEG. The difference to the TSEG implemented in real q35's
MCH (Memory Controller Hub) is that it can offer one extra size to the guest OS
apart from the standard TSEG's 1, 2, and 8 MiB and that size can be selected in
1 MiB increments. Maximum may vary based on QEMU and is way too big, so we
don't need to check for the maximum here. Similarly to the memory size we'll
leave it to the hypervisor to try satisfying that and giving us an error message
in case it is not possible.

Currently we accept and correctly parse this chardev XML:
...
<channel type='tcp'>
<source mode='connect'/>
<source mode='bind' host='localhost'/>
<source service='4567'/>
<target type='virtio' name='test'/>
</channel>
...
The parsed formatted XML is:
...
<channel type='tcp'>
<source mode='connect' host='localhost' service='4567'/>
<target type='virtio' name='test'/>
</channel>
...
That behavior is super wrong and should not be allowed. If you notice
the current parse takes the first found attribute and uses that value,
so for example from the "<source mode='bind' host='localhost'/>" only
the "host" attribute is used. It works the same way for all possible
attributes that we are able to parse for source element.
This patch enforces providing only one source element for all character
devices, only for UDP type we allow to provide two source elements
since you can specify both modes.

it's parsed as:

<listen type='address'/>
</graphics>
but if the resulting XML is parsed again the output is:
<graphics type='vnc' port='-1' autoport='yes'>
<listen type='address'/>
</graphics>
and this should not happen. The XML have to always remain the same
after it was already parsed by libvirt.
