Create a new function qemuPCIAddressValidate and call it everywhere
the user might supply an incorrect address:
* qemuCollectPCIAddress for domain definition
* qemuDomainPCIAddressEnsureAddr and ReleaseSlot for hotplug

Slot and function shouldn't be wrong at this point, since values
out of range should be rejected by the XML parser.

Change QEMU_PCI_ADDRESS_LAST_SLOT to the number of slots in the bus,
not the maximum slot value, to match QEMU_PCI_ADDRESS_LAST_FUNCTION
and rename them both to have _LAST at the end.

Use the same formatting as we do for XML in error and debug outputs.

Bus and domain need to be checked as well, otherwise we might
get false positives when searching for multi-function devices.

The error message reported when attempting to change/get persistent
configuration of a transient domain suggests that changes are being
made. Reword it to suit getter APIs too.

Before:
$ virsh vcpucount transient-domain --config
error: Requested operation is not valid: cannot change persistent config of a transient domain

After:
$ virsh vcpucount transient-domain --config
error: Requested operation is not valid: transient domains do not have any persistent config

Until now tranisent networks weren't really useful as libvirtd wasn't
able to remember them across restarts. This patch adds support for
loading status files of transient networks (that already were generated)
so that the status isn't lost.

This patch chops up virNetworkObjUpdateParseFile and turns it into
virNetworkLoadState and a few friends that will help us to load status
XMLs and refactors the functions that are loading the configs to use
them.

For consistency with other functions in PowerPC CPU driver, the two
functions are renamed as ppcUpdate and ppcDataFree, respectively.

The cpu_map.xml file is there to separate CPU model definitions from the
code. Having the only interesting data for PowerPC models only in the
source code. This patch moves this data to the XML file and removes the
hardcoded list completely.

PowerPC CPUs are either identical or incompatible and thus we just need
to look up the right model for given PVR without pretending we have
several candidates which we may choose from.

The function is also renamed as ppcDecode to match other functions in
PowerPC CPU driver.

Baseline API is supposed to return guest CPU definition that can be used
on any of the provided host CPUs. Since PowerPC CPUs are either
identical or incompatible, the API just needs to check that all provided
CPUs are identical. Previous implementation was completely bogus.

The function is also renamed as ppcBaseline to match other functions in
PowerPC CPU driver.

When ppcVendorLoad fails to parse the vendor element for whatever
reason, it is supposed to ignore it and return 0 rather than -1. The
patch also removes PowerPC vendor string from the XML as it is not
actually used for anything.

Make getting node CPU data for PowerPC unsupported on other
architectures. The function is also renamed as ppcNodeData to match
other functions in PowerPC CPU driver.

Revert the condition to make it easier to read. The function is also
renamed as ppcCompare to match other functions in PowerPC CPU driver.

The API can be used to check if the model is on the supported models
list, which needs to be done in several places.

This patch factors out the vCPU count retrieval including fallback means
into vshCPUCountCollect() and removes the duplicated code to retrieve
individual counts.

The --current flag (this flag is assumed by default) now works also with
--maximum or --active without the need to explicitly specify the state
of the domain that is requested.

This patch also fixes the output of "virsh vcpucount domain" on inactive
domains:

Before:
$ virsh vcpucount domain
maximum      config         4
error: Requested operation is not valid: domain is not running
current      config         4
error: Requested operation is not valid: domain is not running

After:
$virsh vcpucount domain
maximum      config         4
current      config         4

.. and for transient domains too:

Before:
$ virsh vcpucount transient-domain
error: Requested operation is not valid: cannot change persistent config of a transient domain
maximum      live           3
error: Requested operation is not valid: cannot change persistent config of a transient domain
current      live           1

After:
$ virsh vcpucount transient-domain
maximum      live           3
current      live           1

Currently, -device xxx still doesn't work well for ppc64 platform.
It's better use legacy USB option with default for ppc64.

When running unprivileged, virSetUIDGIDWithCaps will fail because it
tries to add the requested capabilities to the permitted and effective
sets.

Detect this case, and invoke the child with cleared permitted and
effective sets.  If it is a setuid program, it will get them.

Some care is needed also because you cannot drop capabilities from the
bounding set without CAP_SETPCAP.  Because of that, ignore errors from
setting the bounding set.

The need_prctl variable is not really needed.  If it is false,
capng_apply will be called twice with the same set, causing
a little extra work but no problem.  This keeps the code a bit
simpler.

It is also clearer to invoke capng_apply(CAPNG_SELECT_BOUNDS)
separately, to make sure it is done while we have CAP_SETPCAP.

Using of a incorrect value for the --holdtime option was silently
ignored and 0 was used. In case a negative number was used, it
overflowed as the API expects a unsigned int.

Fix the data type and getter function type and report errors on
incorrect values.

Rename the get_integer_keycode helper to vshKeyCodeGetInt and get rid of
a unneeded typecast.

The rng schema for <controller> had been non-specific about which
types of controllers allowed which models, and also allowed the
num_queues attribute (since that hasn't been released yet, should we
rename it to "numQueues"?) and <master> subelement to be included for
any controller type. In reality, half of the models are allowed only
for type='scsi', and the other half only for type='usb', num_queues is
allowed only for type='scsi', and <master> only for type='usb'.

This patch makes a separate <group> for type='scsi' and type='usb',
with each group allowing only the appropriate model values, and
allowing num_queue and <master> only when appropriate.

<interleave> also hadn't been specified, forcing a specific order of
subelements, which should never be done. (Note that the <interleave>
had to surround the main element attributes that are in the <group>
subelements, due to one of the <group>s containing a subelement).

When turning a started persistent network into a transient one we forgot
to remove the autostart flag that is no longer valid at that point.

To tell libvirt-{qemu,lxc}.h shouldn't be included either.

With this patch, include public headers in "" form is only allowed
for "internal.h". And only the external tools (examples|tools|python
|include/libvirt) can include the public headers in <> form.

Directories python/tools/examples should include them in <> form,
though this patch allows "" form in these directories by excluding
them, a later patch will do the cleanup.

gnulib is excluded.

Commit 2d25fd4f removed the including of "libvirt/libvirt.h",
which breaks the build. Pushed under build-breaker rule.

The recent qemu requires "0x" prefix for the disk wwn, this patch
changes virValidateWWN to allow the prefix, and prepend "0x" if
it's not specified. E.g.

qemu-kvm: -device scsi-hd,bus=scsi0.0,channel=0,scsi-id=0,lun=0,\
drive=drive-scsi0-0-0-0,id=scsi0-0-0-0,wwn=6000c60016ea71ad:
Property 'scsi-hd.wwn' doesn't take value '6000c60016ea71ad'

Though it's a qemu regression, but it's nice to allow the prefix,
and doesn't hurt for us to always output "0x".

Which is already included in "internal.h", later patch will add
syntax-check to avoid it.

    if test $? != 0; then

No reason to include it in both "if" and "else" branches.
