Sometimes we want to call virCPUGetHost only when it is implemented for
a given architecture to avoid logging expected and possibly misleading
errors. The new virCPUGetHostIsSupported API may be used to guard such
calls to virCPUGetHost.

Use "virNetworkObj" as a prefix for any external API in virnetworkobj.

Also a couple of functions were local to virnetworkobj.c, so remove their
external defs in virnetworkobj.h.

Rename the API to be a better description of what it does. Besides, a
subsequent patch will rename virNetworkAssignDef to virNetworkObjAssignDef
so rather than make that patch confusing we'll take the intermittent step
in this patch.

Move all the virNetworkObj related API/data structures into their own
modules virnetworkobj.{c,h} from the network_conf.{c,h}

This new internal API makes a copy of virCPUDef while removing all
features which would block migration. It uses cpu_map.xml as a database
of such features, which should only be used as a fallback when we cannot
get the data from a hypervisor. The main goal of this API is to decouple
this filtering from virCPUUpdate so that the hypervisor driver can
filter the features according to the hypervisor.

Currently, if we want to zero out disk source (e,g, due to
startupPolicy when starting up a domain) we use
virDomainDiskSetSource(disk, NULL). This works well for file
based storage (storage type file, dir, or block). But it doesn't
work at all for other types like volume and network.

So imagine that you have a domain that has a CDROM configured
which source is a volume from an inactive pool. Because it is
startupPolicy='optional', the CDROM is empty when the domain
starts. However, the source element is not cleared out in the
status XML and thus when the daemon restarts and tries to
reconnect to the domain it refreshes the disks (which fails - the
storage pool is still not running) and thus the domain is killed.

Having to use cpuBaseline with VIR_CONNECT_BASELINE_CPU_EXPAND_FEATURES
flag to expand CPU features is strange. Not to mention that cpuBaseline
can only expand host CPU definitions (i.e., it completely ignores
feature policies). The new virCPUExpandFeatures API is designed to work
with both host and guest CPU definitions.

The global functions virNetDevReplaceMacAddress(),
virNetDevReplaceNetConfig(), virNetDevRestoreMacAddress(), and
virNetDevRestoreNetConfig() are no longer used, as their functionality
has been replaced by virNetDev(Save|Read|Set)NetConfig().

The static functions virNetDevReplaceVfConfig() and
virNetDevRestoreVfConfig() were only used by the above-named global
functions that were removed.

These three functions are destined to replace
virNetDev(Replace|Restore)NetConfig() and
virNetDev(Replace|Restore)MacAddress(), which both do the save and set
together as a single step. We need to separate the save, read, and set
steps because there will be situations where we need to do something
else in between (in particular, we will need to rebind a VF's driver
after save but before set).

This patch creates the new functions, but doesn't call them - that
will come in a subsequent patch. Note that the new functions to
read/write the file that stores the original network config now uses
JSON rather than plaintext (it still recognizes the old format as well
though, so it won't get confused during an upgrade).

Keep track of the assigned mediated devices the same way we do it for
the rest of hostdevs. Methods like 'Prepare', 'Update', and 'ReAttach'
are introduced by this patch.

That file has only two exported files and each one of them has
different naming.  virNode is what all the other files use, so let's
use it.  It wasn't used before because the clash with public API
naming, so let's fix that by shortening the name (there is no other
private variant of it anyway).

There is no "node driver" as there was before, drivers have to do
their own ACL checking anyway, so they all specify their functions and
nodeinfo is basically just extending conf/capablities.  Hence moving
the code to src/conf/ is the right way to go.

Also that way we can de-duplicate some code that is in virsysfs and/or
virhostcpu that got duplicated during the virhostcpu.c split.  And
Some cleanup is done throughout the changes, like adding the vir*
prefix etc.

There is no reason for it not to be in the utils, all global symbols
under that file already have prefix vir* and there is no reason for it
to be part of DRIVER_SOURCES because that is just a leftover from
older days (pre-driver modules era, I believe).

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.
