Return 0 instead of ERR_NO_SUPPORT in each driver
where we don't support managed save or -1 if
the domain does not exist.
This avoids spamming daemon logs when 'virsh dominfo' is run.

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.

It's possible to create a container with existing
disk image as root filesystem. You need to remove
existing disks from PCS VM config and then add a new
one, pointing to your image. And then call PrlVm_RegEx
with PRNVM_PRESERVE_DISK flag.
With this patch you can create such container with
something like this for new domain XML config:
<filesystem type='file' accessmode='passthrough'>
<driver type='ploop' format='ploop'/>
<source file='/path-to-image'/>
<target dir='/'/>
</filesystem>

PCS removes disk image from filesystem, if you remove it
from config. There is a special flag PVCF_DETACH_HDD_BUNDLE
which allow to remove disk only from VM/CT config.
If you call virDomainDefine and remove some disk from
config it should be preserved, so call PrlVm_CommitEx
always with flag PVCF_DETACH_HDD_BUNDLE.

The virDomainDefineXMLFlags and virDomainCreateXML APIs both
gain new flags allowing them to be told to validate XML.
This updates all the drivers to turn on validation in the
XML parser when the flags are set
The virDomainDefParse* and virDomainDefFormat* methods both
accept the VIR_DOMAIN_XML_* flags defined in the public API,
along with a set of other VIR_DOMAIN_XML_INTERNAL_* flags
defined in domain_conf.c.
This is seriously confusing & error prone for a number of
reasons:
- VIR_DOMAIN_XML_SECURE, VIR_DOMAIN_XML_MIGRATABLE and
VIR_DOMAIN_XML_UPDATE_CPU are only relevant for the
formatting operation
- Some of the VIR_DOMAIN_XML_INTERNAL_* flags only apply
to parse or to format, but not both.
This patch cleanly separates out the flags. There are two
distint VIR_DOMAIN_DEF_PARSE_* and VIR_DOMAIN_DEF_FORMAT_*
flags that are used by the corresponding methods. The
VIR_DOMAIN_XML_* flags received via public API calls must
be converted to the VIR_DOMAIN_DEF_FORMAT_* flags where
needed.
The various calls to virDomainDefParse which hardcoded the
use of the VIR_DOMAIN_XML_INACTIVE flag change to use the
VIR_DOMAIN_DEF_PARSE_INACTIVE flag.

For SCSI and SATA devices controller and unit are used
to specify drive address. For IDE devices - bus specifies
IDE bus, becase usually there are 2 IDE buses on IDE
controller.
Parallels SDK allows to set drive position by calling
PrlVmDev_SetStackIndex. Since PCS VMs have only one
controller of each type, for SATA and SCSI devices it
simple means position on bus, for IDE devices -
2 * bus_number + position_on_bus.
This patch fixes mapping from libvirt's disk->info.addr.drive
to parallels's 'StackIndex'.

Rewrite code, which applies domain configuration given

This code first check if there are unsupported parameters
in domain XML and if yes - reports error. Some of such

The virStoragePoolSourceFindDuplicate only checks the incoming definition
against the same type of pool as the def; however, for "scsi_host" and
"fc_host" adapter pools, it's possible that either some pool "scsi_host"
adapter definition is already using the scsi_hostN that the "fc_host"
adapter definition wants to use or some "fc_host" pool adapter definition
is using a vHBA scsi_hostN or parent scsi_hostN that an incoming "scsi_host"
definition is trying to use.
This patch adds the mismatched type checks and adds extraneous comments
to describe what each check is determining.
This patch also modifies the documentation to be describe what scsi_hostN
devices a "scsi_host" source adapter should use and which to avoid. It also
updates the parent definition to specifically call out that for mixed
environments it's better to define which parent to use so that the duplicate
pool checks can be done properly.
Since the secondary drivers are only active when the primary
driver is also the Parallels driver, there is no need to use the
different type specific privateData fields. The object that was
being stored in the storagePrivateData can easily be kept in the
parallelsConn struct instead.
To prepare for introducing a single global driver, rename the
virDriver struct to virHypervisorDriver and the registration
API to virRegisterHypervisorDriver()
Add files parallels_sdk.c and parallels_sdk.h for code
which works with SDK, so libvirt's code will not mix with
dealing with parallels SDK.
To use Parallels SDK you must first call PrlApi_InitEx function,
and then you will be able to connect to a server with
PrlSrv_LoginLocalEx function. When you've done you must call
PrlApi_Deinit. So let's call PrlApi_InitEx on first .connectOpen,
count number of connections and deinitialize, when this counter
becomes zero.

Coverity complains that calling virNetworkDefFree(def), then jumping
to the cleanup: label which calls virNetworkDefFree(def) could result
in a double_free. Just remove the call from the if statement.
Libvirt measures vram in Kbytes, not in bytes, so calculation
of Mbytes was incorrect. PCS server can take vram argument
with units, so I added K postfix to make params a little bit clearer.
There were numerous places where numatune configuration (and thus
domain config as well) was changed in different ways. On some
places this even resulted in persistent domain definition not to be
stable (it would change with daemon's restart).
In order to uniformly change how numatune config is dealt with, all
the internals are now accessible directly only in numatune_conf.c and
outside this file accessors must be used.

So far, we only report an error if formatting the siblings bitmap

Only three other callers possibly call closedir on a NULL argument.
Even though these probably won't be used on FreeBSD where this crashes,
let's be nice and only call closedir on an actual directory stream.
4d06af97d3 introduced a possible memory

A future patch wants to create disk definitions with non-zero
default contents; to avoid crashes, all callers that allocate
a disk definition should go through a common point.
I found allocation points by looking for any code that increments
ndisks, as well as any matches for ALLOC.*disk. Most places that
modified ndisks were covered by the parse from XML to domain/device
definition by initial domain creation or device hotplug; I also
hand-checked all drivers that generate a device struct on the
fly during getXMLDesc.
