e6c29f09e5 conf: Add support for specifying CPU max physical address size
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.

1e4aff444c virDomainBackupDefFormat: Propagate private data callbacks
The formatter for the backup job data didn't pass the virDomainXMLOption
struct to the disk formatter which meant that the private data of the
disk source were not formatted.

This didn't pose a problem for now as the blockjob list remembered the
nodenames for the jobs, but the backup source lost them.

5c254bb541 conf: Store SCSI bus length in virDomainDef
Libvirt assumes that a SCSI bus can fit up to 8 devices
(including controller itself), except for so called wide bus
which can accommodate up to 16 devices (again, including
controller). This plays important role when computing 'drive'
address in virDomainDiskDefAssignAddress(). So far, the only
driver that enables wide SCSI bus is VMX. But with newer
releases, ESX is capable of "super wide" bus (64 devices).

We can blindly bump the limit in our code because then we would
compute address that's invalid for older ESX versions that we
still want to support.

Unfortunately, I haven't found a better place where to store this
than virDomainDef.

c8238579fb lib: Drop internal virXXXPtr typedefs
Historically, we declared pointer type to our types:

  typedef struct _virXXX virXXX;
  typedef virXXX *virXXXPtr;

But usefulness of such declaration is questionable, at best.
Unfortunately, we can't drop every such declaration - we have to
carry some over, because they are part of public API (e.g.
virDomainPtr). But for internal types - we can do drop them and
use what every other C project uses 'virXXX *'.

This change was generated by a very ugly shell script that
generated sed script which was then called over each file in the
repository. For the shell script refer to the cover letter:

d3aa28925f Add a check attribute on the mac address element
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.

1d0c3c3a62 cachetune schema: a looser check for the order of <cache> and <monitor> element
Originally, inside <cputune/cachetune>, it requires the <cache> element to
be in the position before <monitor>, and following configuration is not
permitted by schema, but it is better to let it be valid.

  <cputune>
    <cachetune vcpus='0-1'>
      <monitor level='3' vcpus='0-1'/>
            ^
            |__ Not permitted originally because it is in the place
                before <cache> element.

      <cache id='1' level='3' type='both' size='3' unit='MiB'/>
    </cachetune>
    ...
  </cputune>

And, let schema do more strict check by identifying following configuration to
be invalid, due to <cachetune> should contain at least one <cache> or <monitor>
element.

  <cputune>
    <cachetune vcpus='0-1'>

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.

1bd5a08d38 conf, schema, docs: Add support for TSEG size setting
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.

    <source mode='bind' host='localhost'/>
    <source service='4567'/>
    <target type='virtio' name='test'/>

  ...
  <channel type='tcp'>
    <source mode='connect' host='localhost' service='4567'/>
    <target type='virtio' name='test'/>

  ...

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.
