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.

I've noticed that these APIs are missing @flags argument. Even
though we don't have a use for them, it's our policy that every
new API must have @flags.

To use post-copy one has to start the migration with
VIR_MIGRATE_POSTCOPY flag and, while migration is in progress, call
virDomainMigrateStartPostCopy() to switch from pre-copy to post-copy.

For setting passwords of users inside the domain.
With the VIR_DOMAIN_PASSWORD_ENCRYPTED flag set, the password
is assumed to be already encrypted by the method required
by the guest OS.

Define helper function virDomainInterfaceFree, which allows
the upper layer application to free the domain interface object
conveniently.
The API is going to provide multiple methods by flags, e.g.
* Query guest agent
* Parse DHCP lease file
include/libvirt/libvirt-domain.h
* Define virDomainInterfaceAddresses, virDomainInterfaceFree
* Define structs virDomainInterface, virDomainIPAddress
src/driver-hypervisor.h:
* Define domainInterfaceAddresses
src/libvirt-domain.c:
* Implement virDomainInterfaceAddresses
* Implement virDomainInterfaceFree
src/libvirt_public.syms:
* Export the new symbols

Add virDomainPinIOThread to allow setting the CPU affinity for a specific
IOThread based on the output generated from virDomainGetIOThreadsInfo
The API supports updating both the --live domain and the --config data
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.

With the large number of APIs in libvirt the driver.h file,
it is easy to get lost looking for things. Split each driver
into a separate header file based on the functional driver
groups.
