This reverts commit 92840eb3a7.

More recent reviews/changes don't have the vir*ObjNew APIs
consuming the @def, so remove from Interface as well. Changes
needed to also deal with conflicts from commit id '46f5eca4'.

b887d7b0c7 maint: correct quoting for gl_WARN_ADD
3 out of 4 uses of gl_WARN_ADD() were incorrectly adding "" around
the argument, which in turn resulted in the argument being used
unquoted (configure had gl_positive=""-fstack-protector-all"",
rather than the intended gl_positive="-fstack-protector-all").

b988f794e3 daemon: logging: Fix --verbose option being ignored by the daemon
Commit 94c465d0 refactored the logging setup phase but introduced an
issue, where the daemon ignores verbose mode when there are no outputs
defined and the default must be used. The problem is that the default
output was determined too early, thus ignoring the potential '--verbose'
option taking effect. This patch postpones the creation of the default
output to the very last moment when nothing else can change. Since the
default output is only created during the init phase, it's safe to leave
the pointer as NULL for a while, but it will be set eventually, thus not
affecting runtime.
Patch also adjusts both the other daemons.

1f43393283 qemu: Handle host devices not being available better
We can't retrieve the isolation group of a device that's not present
in the system. However, it's very common for VFs to be created late
in the boot, so they might not be present yet when libvirtd starts,
which would cause the guests using them to disappear.

Moreover, for other architectures and even ppc64 before isolation
groups were introduced, it's considered perfectly fine to configure a
guest to use a device that's not yet (or no longer) available to the
host, with the obvious caveat that such a guest won't be able to
start before the device is available.

In order to be consistent, when a device's isolation group can't be
determined fall back to not isolating it rather than erroring out or,
worse, making the guest disappear.

e02ff020ca conf: don't close the source element inside different function
While formatting disk or chardev element they both uses
virDomainDiskSourceDefFormatSeclabel() function which also closes
the source element.  This is not extendable.

Use the new virXMLFormatElement() to properly format the source
element with possible child elements.

As a side effect it fixes a bug in disk source formatting.

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

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.

d9fc08d103 vmx: do not treat controllers as implicit devices
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.

21bfd1e9b9 conf: error out for multiple source elements while parsing chardev
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.
