This patch also fixes 2 possible memory leaks on error path in the code

and a listen address string could be leaked.

Also break a few very long lines and reflow code that fits now.

Currently the RPC protocol files can contain annotations after

Refactoring done in 19c6ad9a didn't
correctly take into account the order cgroup limit modification needs to
be done in. This resulted into errors when decreasing the limits.

The operations need to take place in this order:

decrease hard limit
change swap hard limit

or

change swap hard limit
increase hard limit

This patch also fixes the check if the hard_limit is less than
swap_hard_limit to print better error messages. For this purpose I
introduced a helper function virCompareLimitUlong to compare limit
values where value of 0 is equal to unlimited. Additionally the check is
now applied also when the user does not provide all of the tunables
through the API and in that case the currently set values are used.

After discussions with systemd developers it was decided that
a better default policy for resource partitions is to have
3 default partitions at the top level

   /system   - system services
   /machine - virtual machines / containers
   /user    - user login session

This ensures that the default policy isolates guest from
user login sessions & system services, so a mis-behaving
guest can't consume 100% of CPU usage if other things are
contending for it.

Thus we change the default partition from /system to
/machine

Wrong use of the parentheses causes "rc" always having a boolean value,
either "1" or "0", and thus we can't get the detailed error message
when it fails:

Commit d04916fa introduced a regression in audit quality - even
though the code was computing the proper escaped name for a
path, it wasn't feeding that escaped name on to the audit message.
As a result, /var/log/audit/audit.log would mention a pair of
fields class=path path=/dev/hpet instead of the intended
class=path path="/dev/hpet", which in turn caused ausearch to
format the audit log with path=(null).

Also change its return value from int to bool.

Each bus is represented as an array of 32 8-bit integers
where each bit represents a PCI function and each byte represents
a PCI slot.

Uses just one bus so far.

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

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.
