Parallels Cloud Server uses virtual networks model for network
configuration. It uses own tools for virtual network management.
So add network driver, which will be responsible for listing
virtual networks and performing different operations on them
(in consequent patched).

This patch only allows listing virtual network names, without
any parameters like DHCP server settings.

Allow changing network interfaces in domain configuration.

ifname is used as iterface identifier: if there is interface
with some ifname in old config and there are no interfaces with
such name in the new config - issue prlctl command to delete
the network interface. And vice versa - if interface with
some ifname exists only in new config - issue prlctl command
to create it.

There are no storage pools in Parallels Cloud Server -
All VM data stored in a single directory: config, snapshots,
memory dump together with disk images.

Let's look through list of VMs and create a storage pool for
each directory, containing VMs.

So if you have 3 vms: /var/parallels/vm-1.pvm,
/var/parallels/vm-2.pvm and /root/test.pvm - 2 storage pools
appear: -var-parallels and -root. xml descriptions of the pools
will be saved in /etc/libvirt/parallels-storage, so UUIDs will
not change netween connections to libvirt.

For S390, the default console target type cannot be of type 'serial'.
It is necessary to at least interpret the 'arch' attribute
value of the os/type element to produce the correct default type.

Therefore we need to extend the signature of defaultConsoleTargetType
to account for architecture. As a consequence all the drivers
supporting this capability function must be updated.

Despite the amount of changed files, the only change in behavior is
that for S390 the default console target type will be 'virtio'.

N.B.: A more future-proof approach could be to to use hypervisor
specific capabilities to determine the best possible console type.
For instance one could add an opaque private data pointer to the
virCaps structure (in case of QEMU to hold capsCache) which could
then be passed to the defaultConsoleTargetType callback to determine
the console target type.
Seems to be however a bit overengineered for the use case...

Let's change URI to parallels:///system. Parallels Server supports
creating VMs from non-privileged accounts, but it's not main usage
scenario and it may be forbidden in the future.

Also containers, which will be supported by the driver, can be managed

As the consensus in:
https://www.redhat.com/archives/libvir-list/2012-July/msg01692.html,
this patch is to destroy conf/virdomainlist.[ch], folding the
helpers into conf/domain_conf.[ch].

* src/Makefile.am:
  - Various indention fixes incidentally
  - Add macro DATATYPES_SOURCES (datatypes.[ch])
  - Link datatypes.[ch] for libvirt_lxc

* src/conf/domain_conf.c:
  - Move all the stuffs from virdomainlist.c into it
  - Use virUnrefDomain and virUnrefDomainSnapshot instead of
    virDomainFree and virDomainSnapshotFree, which are defined
    in libvirt.c, and we don't want to link to it.
  - Remove "if" before "free" the object, as virObjectUnref
    is in the list "useless_free_options".

* src/conf/domain_conf.h:
  - Move all the stuffs from virdomainlist.h into it
  - s/LIST_FILTER/LIST_DOMAINS_FILTER/

* src/libxl/libxl_driver.c:
  - s/LIST_FILTER/LIST_DOMAINS_FILTER/
  - no (include "virdomainlist.h")

This converts the following public API datatypes to use the
virObject infrastructure:

  virDomainPtr
  virDomainSnapshotPtr
  virInterfacePtr
  virNetworkPtr
  virNodeDevicePtr
  virNWFilterPtr
  virSecretPtr
  virStreamPtr
  virStorageVolPtr
  virStoragePoolPtr

The code is significantly simplified, since the mutex in the
virConnectPtr object now only needs to be held when accessing
the per-connection virError object instance. All other operations
are completely lock free.

To create a new VM in Parallels Clud Server we should issue

where VM should be created. VM's storage will be in that

Parallels Cloud Server has one serious discrepancy with libvirt:
libvirt stores domain configuration files in one place, and storage
files in other places (with the API of storage pools and storage volumes).
Parallels Cloud Server stores all domain data in a single directory,
for example, you may have domain with name fedora-15, which will be
located in '/var/parallels/fedora-15.pvm', and it's hard disk image will be
in '/var/parallels/fedora-15.pvm/harddisk1.hdd'.

I've decided to create storage driver, which produces pseudo-volumes
(xml files with volume description), and they will be 'converted' to
real disk images after attaching to a VM.

So if someone creates VM with one hard disk using virt-manager,
at first virt-manager creates a new volume, and then defines a
domain. We can lookup a volume by path in XML domain definition
and find out location of new domain and size of its hard disk.

Add parallelsDomainDefineXML function, it works only for existing
domains for the present.

It's too hard to convert libvirt's XML domain configuration into
Parallel's one, so I've decided to compare virDomainDef structures:
current domain definition and the one created from XML, given to
the function. And change only different parameters.

Currently only name, description, number of cpus, memory amount
and video memory can be changed.

Video device and console added, because libvirt supposes that
VM must always have one video device, if there are some
graphics and one console.

Parallels driver is 'stateless', like vmware or openvz drivers.
It collects information about domains during startup using
command-line utility prlctl. VMs in Parallels are identified by UUIDs
or unique names, which can be used as respective fields in
virDomainDef structure. Currently only basic info, like
description, virtual cpus number and memory amount, is implemented.
Querying devices information will be added in the next patches.

Parallels doesn't support non-persistent domains - you can't run
a domain having only disk image, it must always be registered
in system.

Functions for querying domain info have been just copied from
test driver with some changes - they extract needed data from
previously created list of virDomainObj objects.
