Fix the warning generated on PPC by virt-host-validate for IOMMU.
In case of PPC, IOMMU in the host kernel either has it or it's not
compiled in. The /sys/kernel/iommu_groups check is good enough to
verify if it was compiled with the kernel or not.
Modify the error message when "if (sb.st_nlink <= 2)" to indicate
what the problem would be since there would be no @bootarg.

When parsing the config, we look for the SCSI controllers one by one,
remembering their models, then let virDomainDefAddImplicitDevices
add them if any SCSI disk is using them.
Since these controllers are not really implicit (they are present
in the source config), add them explicitly.
This patch maintains the behavior of not adding a controller
if it was present in the config, but no disk was using it.
This also resolves the memory leak of virVMXParseConfig overwriting
the video device added by calling virDomainDefAddImplicitDevices
before the parsing is finished.

For selected hostdev types, we validate that the address type
matches the subsystem type when parsing the XML.
Move it to the validation phase, to allow extending the checks
to other subsystem types without making existing domains disappear.
At the time the check was written virtuozzo did not use disabled items in boot
order configuration. Boot items were always enabled. Now they can be disabled
as well. Supporting such items is easy - they just should be ignored.
HTML5 obsoletes the 'name' attribute in favor of 'id',
and our TOC generator apparently follows the recommendation
to the letter, resulting in a broken TOC if you use the
old-school attribute.

When parsing bootable devices, we maintain a bitmap of used
<boot order=""> elements. Use it in the post-parse function
to figure out whether the user tried to mix per-device and
per-domain boot elements.
This removes the need to count them twice.
These functions contain the post-parse steps common for all drivers.
Rename it to use the 'Common' prefix, instead of the vagueness
of 'Internal', leaving 'Internal' available for other vague uses.
Since the source element is parsed only once for these type of
character devices we don't have to use temporary variable and
check whether the variable was already set.

The extra check whether (connect|bind)(Host|Service) was set is
required because for UDP chardev there can be two source elements.
Without the check there could be a memory leak.

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.

Since its introduction in commit 874e65aa, if someone requests:
<os><bios useserial="yes"/><os/>
we report an error if we cannot successfully count the number
of serial devices via an XPath query.
Instead of fixing the check (and moving it to the validation phase,
to prevent existing domains from disappearing), drop it completely.
For QEMU, the number of serials is checked when building the command
line.
When security drivers are active but confinement is not enabled,
there is no need to autogenerate <seclabel> elements when starting
a domain def that contains no <seclabel> elements. In fact,
autogenerating the elements can result in needless save/restore and
migration failures when the security driver is not active on the
restore/migration target.
This patch changes the virSecurityManagerGenLabel function in
src/security_manager.c to only autogenerate a <seclabel> element
if none is already defined for the domain *and* default
confinement is enabled. Otherwise the needless <seclabel>
autogeneration is skipped.

The virDomainDef created by testBuildDomainDef in securityselinuxtest
adds a seclabel but does not increment nseclabels. Also, it should
populate seclabel->model with 'selinux'.
While at it, use the secdef itself to populate values instead of
the indirection through def->seclabels[0].

Use the new facility which allows to ignore failures in post parse
callbacks if they are not fatal so that VM configs are not lost if the
emulator binary is missing.
If qemuCaps can't be populated on daemon restart skip certain portions
of the post parse callbacks during config reload and re-run the callback
during VM startup.
This fixes VMs vanishing if the emulator binary was broken or
uninstalled and libvirtd was restarted.
qemuDomainControllerDefPostParse assigns the default USB controller
model when it was not specified by the user. Skip this step if @qemuCaps
is missing so that we don't fill wrong data. This will then be fixes by
re-running the post parse callback.
