669018bc9c storage: optional 'refresh' elemement on pool
The new 'refresh' element can override the default refresh operations
for a storage pool. The only currently supported override is to set
the volume allocation size to the volume capacity. This can be specified
by adding the following snippet:

<pool>
...
  <refresh>
    <volume allocation='capacity'/>
  </refresh>
...
</pool>

This is useful for certain backends where computing the actual allocation
of a volume might be an expensive operation.

5d010c3df6 network: avoid trying to create global firewall rules if unprivileged
The unprivileged libvirtd does not have permission to create firewall
rules, or bridge devices, or do anything to the host network in
general. Historically we still activate the network driver though and
let the network start API call fail.

The startup code path which reloads firewall rules on active networks
would thus effectively be a no-op when unprivileged as it is impossible
for there to be any active networks

With the change to use a global set of firewall chains, however, we now
have code that is run unconditionally.

Ideally we would not register the network driver at all when
unprivileged, but the entanglement with the virt drivers currently makes
that impractical. As a temporary hack, we just make the firewall reload
into a no-op.

686803a1a2 network: split setup of ipv4 and ipv6 top level chains
During startup libvirtd creates top level chains for both ipv4
and ipv6 protocols. If this fails for any reason then startup
of virtual networks is blocked.

The default virtual network, however, only requires use of ipv4
and some servers have ipv6 disabled so it is expected that ipv6
chain creation will fail. There could equally be servers with
no ipv4, only ipv6.

This patch thus makes error reporting a little more fine grained
so that it works more sensibly when either ipv4 or ipv6 is
disabled on the server. Only the protocols that are actually
used by the virtual network have errors reported.

9f4e35dc73 network: improve error report when firewall chain creation fails
During startup we create some top level chains in which all
virtual network firewall rules will be placed. The upfront
creation is done to avoid slowing down creation of individual
virtual networks by checking for chain existance every time.

There are some factors which can cause this upfront creation
to fail and while a message will get into the libvirtd log
this won't be seen by users who later try to start a virtual
network. Instead they'll just get a message saying that the
libvirt top level chain does not exist. This message is
accurate, but unhelpful for solving the root cause.

This patch thus saves any error during daemon startup and
reports it when trying to create a virtual network later.

virCapsEnum report is an internal bool indicating whether we
should format the enum in the XML at all. This is unused for
now but will be handled in future patches.

We use a plain bool instead of tristate because the case here
is a bit different than the explicit @supported output. We
already report the equivalent of supported=YES|NO based on
what enum values are filled in. This adds report=false to
handle the ABSENT case.

ad12932481 tests: domcaps: Remove 'full' test
The 'full' test verifies the output of a virDomainCapsPtr built
by hand. It has the following problems:

The domcaps test suite nowadays has 3 hypervisor driver implementations
which should give us plenty of opportunity to get full domcaps coverage.
I don't think this test has much value. And it has the following issues:

- Requires manual intervention to test new domcaps XML, which is easy
  to miss, for example gic bits aren't covered there.
- The SET_ALL_BITS trick it uses to fill in enums will output
  values that are never reported by any driver implementation
  (strings like 'default')

Let's remove it

2e556e00ca storageVolWipePattern: Don't take shortcut to refreshPool()
In d16f803d78 we've tried to solve an issue that after wiping an
image its format might have changed (e.g. from qcow2 to raw) but
libvirt wasn't probing the image format. We fixed this by calling
virStorageBackendRefreshVolTargetUpdate() which is what
refreshPool() would end up calling. But this shortcut is not good
enough because the function is called only for local types of
volumes (like dir, fs, netfs). But now that more backends support
volume wiping we have to call the function with more caution.

Class element is not optional. I guess this should not
break users that use virNodeDeviceCreateXML because
they probably specify only scsi_host capability on

from udev after device appeared.
