Create a new API that will allow an adjustment of IOThread
polling parameters for the specified IOThread. These parameters
will not be saved in the guest XML. Currently the only parameters
supported will allow the hypervisor to adjust the parameters used
to limit and alter the scope of the polling interval. The polling
interval allows the IOThread to spend more or less time processing
in the guest.
Based on code originally posted by Pavel Hrdina <phrdina@redhat.com>
to add virDomainAddIOThreadParams and virDomainModIOThreadParams.
Modification of those changes to use virDomainSetIOThreadParams
instead and remove concepts related to saving the data in guest
XML as well as the way to specifically enable the polling parameters.

Currently the virDrvConnectOpen method is supposed to handle both
opening an explicit URI and auto-probing a driver if no URI is
given. Introduce a dedicated virDrvConnectURIProbe method to enable the
probing functionality to be split from the driver opening functionality.
It is still possible for NULL to be passed to the virDrvConnectOpen
method after this change, because the remote driver needs special
handling to enable probing of the URI against a remote libvirtd daemon.

Similarly to domainSetGuestVcpus this commit adds API which allows to
modify state of individual vcpus rather than just setting the count.
This allows to enable CPUs in specific guest NUMA nodes to achieve any
necessary configuration.
Our internal APIs mostly use virArch rather than strings. Switching
cpuGetModels to virArch will save us from unnecessary conversions in the
future.

To allow finer-grained control of vcpu state using guest agent this API
can be used to individually set the state of the vCPU.
This will allow to better control NUMA enabled guests and/or test
various vCPU configurations.
Add a rather universal API implemented via typed params that will allow
to query the guest agent for the state and possibly other aspects of
guest vcpus.
The virConnectOpenInternal method opens the libvirt client
config file and uses it to resolve things like URI aliases.
There may be driver specific things that are useful to
store in the config file too, so rather than have them
re-parse the same file, pass the virConfPtr down to the
drivers.

Add virDomainGetIOThreadInfo in order to return a list of
virDomainIOThreadInfoPtr structures which list the IOThread ID
and the CPU Affinity map for each IOThread for the domain.
For an active domain, the live data will be returned, while for
an inactive domain, the config data will be returned.
The API supports either the --live or --config flag, but not both.
Also added virDomainIOThreadsInfoFree in order to free the cpumap
and the IOThreadInfo structure.

For stateless, client side drivers, it is never correct to
probe for secondary drivers. It is only ever appropriate to
use the secondary driver that is associated with the
hypervisor in question. As a result the ESX & HyperV drivers
have both been forced to do hacks where they register no-op
drivers for the ones they don't implement.
For stateful, server side drivers, we always just want to
use the same built-in shared driver. The exception is
virtualbox which is really a stateless driver and so wants
to use its own server side secondary drivers. To deal with
this virtualbox has to be built as 3 separate loadable
modules to allow registration to work in the right order.
This can all be simplified by introducing a new struct
recording the precise set of secondary drivers each
hypervisor driver wants
struct _virConnectDriver {
virHypervisorDriverPtr hypervisorDriver;
virInterfaceDriverPtr interfaceDriver;
virNetworkDriverPtr networkDriver;
virNodeDeviceDriverPtr nodeDeviceDriver;
virNWFilterDriverPtr nwfilterDriver;
virSecretDriverPtr secretDriver;
virStorageDriverPtr storageDriver;
};
Instead of registering the hypervisor driver, we now
just register a virConnectDriver instead. This allows
us to remove all probing of secondary drivers. Once we
have chosen the primary driver, we immediately know the
correct secondary drivers to use.

The virDomainDefineXML method is one of the few that still lacks
an 'unsigned int flags' parameter. This will be needed for adding
XML validation to this API. virDomainCreateXML fortunately already
has flags.
virDomainGetFSInfo returns a list of filesystems information mounted in the
guest, which contains mountpoints, device names, filesystem types, and
device aliases named by libvirt. This will be useful, for example, to
specify mountpoints to fsfreeze when taking snapshot of a part of disks.
