f4ea67f5b3 Turn some dual-state int parameters into booleans
The virStateInitialize method and several cgroups methods were
using an 'int privileged' parameter or similar for dual-state
values. These are better represented with the bool type.

2b121dbc10 Add private data pointer to virStoragePool and virStorageVol
This will simplify the refactoring of the ESX storage driver to support
a VMFS and an iSCSI backend.

One of the tasks the storage driver needs to do is to decide which backend
driver needs to be invoked for a given request. This approach extends
virStoragePool and virStorageVol to store extra parameters:

1. privateData: stores pointer to respective backend storage driver.
2. privateDataFreeFunc: stores cleanup function pointer.

virGetStoragePool and virGetStorageVol are modfied to accept these extra
parameters as user params. virStoragePoolDispose and virStorageVolDispose
checks for cleanup operation if available.

The private data pointer allows the ESX storage driver to store a pointer
to the used backend with each storage pool and volume. This avoids the need
to detect the correct backend in each storage driver function call.

b1c88c1476 capabilities: defaultConsoleTargetType can depend on architecture
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...

0b121614a2 xml: print uuids in the warning
In the XML warning, we print a virsh command line that can be used to
edit that XML. This patch prints UUIDs if the entity name contains
special characters (like shell metacharacters, or "--" that would break
parsing of the XML comment). If the entity doesn't have a UUID, just
print the virsh command that can be used to edit it.

4aaa5a723d parallels: change URI to parallels:///system
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
only by root, so /system path is more suitable for this driver.

bb705e2519 Destroy virdomainlist.[ch]
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".

  - Move all the stuffs from virdomainlist.h into it

46ec5f85c8 Convert public datatypes to inherit from virObject
This converts the following public API datatypes to use the
virObject infrastructure:

  virConnectPtr
  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.

7024ddfc09 parallels: implement VM creation
To create a new VM in Parallels Clud Server we should issue
"prlctl create" command, and give path to the directory,
where VM should be created. VM's storage will be in that
directory later. So in this first version find out location
of first VM's hard disk and create VM there.

aa296e6c29 parallels: add storage driver
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.

e356f6100d parallels: implement virDomainDefineXML operation for existing domains
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.

e93c33a987 parallels: add functions to list domains and get info
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.
