These helpers are doing just a read and covert the value, but they
properly size the read limit, handle additional whitespace characters,
and unify error reporting.

Guests are handled in callers, but if something goes wrong (when it
cannot be added to virCapabilities, for example), there's no way for
them to free it properly.

Both QEMU and bhyve are using the same function for setting up the CPU

Move the helper that frees JSON entries put into hash tables into the
JSON module so that it does not have to be reimplemented.

When using thin provisioning, management tools need to resize the disk
in certain cases. To avoid having them to poll disk usage introduce an
event which will be fired when a given offset of the storage is written
by the hypervisor. Together with the API which will be added later, it
will allow registering thresholds for given storage backing volumes and
this event will then notify management if the threshold is exceeded.

'nodeformat' should be used for strings which describe the storage
format object, and 'nodebacking' for the actual storage object itself.

The function has very specific semantics. Split out the part that parses
the backing store specification string into a separate helper so that it
can be reused later while keeping the wrapper with existing semantics.

Note that virStorageFileParseChainIndex is pretty well covered by the
test suite.

It will be useful to set indentation level to 0 after formatting a
nested structure rather than having to track the depth.

Given an SRIOV PF netdev name (e.g. "enp2s0f0") and VF#, this new
function returns the netdev name of the referenced VF device
(e.g. "enp2s11f6"), or NULL if the device isn't bound to a net driver.

This function unbinds a device from its driver, then immediately
rebinds it to its driver again. The code for this new function is just
the 2nd half of virPCIDeviceBindWithDriverOverride(), so that
function's 2nd half is replaced with a call to virPCIDeviceRebind().

This function will be useful in virnetdev.c, so promote it from static.

This patch splits out the part of virNetDevTapCreateInBridgePort()
that would need to be re-done if an existing tap device had to be
re-attached to a bridge, and puts it into a separate function. This
can be used both when an existing domain interface config is updated
to change its connection, and also to re-attach to the "same" bridge
when a network has been stopped and restarted. So far it is used for
nothing.

This function provides the bridge/bond device that the given network
device is attached to. The return value is 0 or -1, and the master
device is a char** argument to the function - this is needed in order
to allow for a "success" return from a device that has no master.

When enabling IPv6 on all interfaces, we may get the host Router
Advertisement routes discarded. To avoid this, the user needs to set
accept_ra to 2 for the interfaces with such routes.

See https://www.kernel.org/doc/Documentation/networking/ip-sysctl.txt
on this topic.

To avoid user mistakenly losing routes on their hosts, check
accept_ra values before enabling IPv6 forwarding. If a RA route is
detected, but neither the corresponding device nor global accept_ra
is set to 2, the network will fail to start.

Add a function getting the name of a network interface out of its index.

virNetlinkCommand() processes only one response message, while some
netlink commands, like route dumping, need to process several.
Add virNetlinkDumpCommand() as a virNetlinkCommand() sister.

Use "virStoragePoolObj" as a prefix for any external API in virstorageobj.

When starting a domain with custom guest CPU specification QEMU may add
or remove some CPU features. There are several reasons for this, e.g.,
QEMU/KVM does not support some requested features or the definition of
the requested CPU model in libvirt's cpu_map.xml differs from the one
QEMU is using. We can't really avoid this because CPU models are allowed
to change with machine types and libvirt doesn't know (and probably
doesn't even want to know) about such changes.

Thus when we want to make sure guest ABI doesn't change when a domain
gets migrated to another host, we need to update our live CPU definition
according to the CPU QEMU created. Once updated, we will change CPU
checking to VIR_CPU_CHECK_FULL to make sure the virtual CPU created
after migration exactly matches the one on the source.

The function is actually in virutil.c, but prototyped in virfile.h.

Use "virNWFilterObj" as a prefix for any external API in virnwfilterobj

Rather than pass the nwfilter object, just pass the def to the function

There's no need to pass the driver pointer to nwfilter_conf, just
pass the configDir.

Whole implementations along with helper totalling screens of code were
conditionally compiled. That made the code totally unreadable and
untestable. Rename functions to have the architecture in the name so
that all can be compiled at the same time and introduce header to allow
testing them all.

After the system has been booted, it should not change.
