NULL value of virDomainVideoAccelDefPtr means default
values for video acceleration, so don't report error in
this case.

If we want to perform some operation and domain state is not suitable
for that operation, we should report error VIR_ERR_OPERATION_INVALID.

When PrlJob_GetRetCode sets second argument to
error value it means sdk function failed and we
must return error from getJobResultHelper.

Return error code, returned by parallels SDK from
waitJob and getJobResult, so that caller can handle
different errors.

Get cdrom devices list from parallels server in
prlsdkLoadDomains and add ability to define a domain
with cdroms.

First, we don't need to call prlsdkApplyConfig after
creating new VM or containers, because it's done in
functions prlsdkCreateVm and prlsdkCreateCt.

No need to check, if domain exists in the list after
prlsdkAddDomain.

Also organize code, so that we can call virObjectUnlock
in one place.

This patch replaces code, which creates domains by
running prlctl command.

prlsdkCreateVm/Ct will do prlsdkApplyConfig, because
we send request to the server only once in this case.

But prlsdkApplyConfig will be called also from
parallelsDomainDefineXML function. There is no problem with
it, parallelsDomainDefineXML will be refactored later.

Rewrite code, which applies domain configuration given
to virDomainDefineXML function to the VM of container
registered in PCS.

This code first check if there are unsupported parameters
in domain XML and if yes - reports error. Some of such
parameters are not supported by PCS, for some - it's not
obvious, how to convert them into PCS's corresponding params,
so let's put off it, and implement only basic params in
this patch.

Change domain state using parallels SDK functions instead of
prlctl command.

We don't need to send events from these functions now, becase
events handler will send them. But we still need to update
virDomainObj in privconn->domains.

Subscribe to events from parallels server. It's
needed for 2 things: to update cached domains list
and to send corresponding libvirt events.

Parallels server sends a lot of different events, in
this patch we handle only some of them. In the future
we can handle for example, changes in a host network
configuration or devices states.

Obtain information about domains using parallels sdk instead of prlctl.
prlsdkLoadDomains functions behaves as former parallelsLoadDomains with
NULL as second parameter (name) - it fills parallelsConn.domains list.

prlsdkLoadDomain is now able to update specified domain by given
virDomainObjPtr.

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.
