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.

Revert @f8172388 which broke the build on Centos 6, because of old
autoconf (< 2.63b) not properly quoting arguments for shell.

Using a variable named 'stat' clashes with the system function
'stat()' causing compiler warnings on some platforms:

libxl/libxl_driver.c: In function 'libxlDomainBlockStatsVBD':
libxl/libxl_driver.c:5387: error: declaration of 'stat' shadows a global declaration [-Wshadow]

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.

If we jump to the error: label and @secbuf is allocated, then it's not
free'd at all.

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.

Rename the original function to virDomainDefPostParseInternal
to allow adding arguments that will be only used by the internal
version.

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.

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.
