This step can be omitted, so that drivers can decide what to do when the
user requests to use default vcpu pinning.

The array doesn't necessarily have the same cardinality as the count of
vCPUs for a domain. Iterating it can cause access beyond the end of the
array.

prlsdkCleanupBridgedNet call should be made strongly after
any actual domain deletion accurs. By doing this we avoid
any potential problems connected with second undefine call
when it is made after first one fails by some reason, and
we detect that network is already deleted.

Currently vz driver unregisters domains when undefine is called,
which is wrong because it contradicts with expected behavior.
All vz domains are persistent, which means that when one is
defined a new bundle directory containing meta data is created.
Undefining domains in a way we do now leaves those directories
undeleted, which prevents subsequent define call for the same
domain xml. I.e. the following sequence define->undefine->define
doesn't work now.
The patch fixes the problem by calling PrlVm_Delete instead of
PrlVm_Unreg detaching all disks prior actually doing this to
prevent images deletion.

The new helper will simplify checking whether the domain config contains
inactive vCPUs.

To support further refactors replace all write access to def->maxvcpus
with a accessor function.

1. Add virCheckFlags() call in vzDomainReboot

In virtuozzo we support only en-us keymap for VMs and containers.
If keymap is specified than check that it's en-us, otherwise
show error message.

We have macros for both positive and negative string matching.
Therefore there is no need to use !STREQ or !STRNEQ. At the same
time as we are dropping this, new syntax-check rule is
introduced to make sure we won't introduce it again.

The name of the variable was misleading. Rename it and it's setting

As far as not every call of prlsdkUUIDParse assume correct UUID
supplied, there is no use to complain about wrong format in it.
Otherwise our log is flooded with false error messages.
For instance, calling prlsdkUUIDParse from prlsdkEventsHandler
works as a filter and in case of uuid absence for event issuer,
we simply know that we shouldn't continue further processing.
Instead of error logging for all calls we should explicitly take
into accaunt where it is called from.

We create a virtual network of special type, which
has the same name as bridge name to create bridged
network adapter in vz. So when we delete such an
adapter we have to remove corresponding virtual
network.

So let's rename prlsdkDelNet to prlsdkCleanupBridgedNet
and don't check for return value.

We support only one IPv4 and one IPv6 default gateway.
If static IPs are not present in instance config,
then we switch on DHCP for this adapter.
PrlVmDevNet_SetAutoApply to makes necessary settings within guest OS
In linux case it creates network startup scripts
/etc/sysconfig/network-scripts/ifcfg-ethN and fills it with necessary
parameters.

Current version of SDK event dispatcing is incorrect. For most VM events (add,
delete etc) issuer type is PIE_DISPATCHER. Actually analyzing issuer type
doesn't have any benifints so this patch get rid of it. All dispatching is done
only on event type.

Remove braces around single-statement blocks in vz_sdk.c

In this patch we add VIR_DOMAIN_DEVICE_NET handlers implementation
for domainAttachDevice and domainDetachDevice callbacks.

As soon as we don't support this operation for hypervisor type domains,
we implement this functionality for containers only.

In detach procedure we find network device by MAC address.
Because PrlVmDevNet_GetMacAddress() returns MAC as a UTF-8 encoded
null-terminated string, we use memcmp() to compare it.
Also we remove corresponding virtual network by prlsdkDelNetAdapter call.

There was many errors in libvirt.log caused by prlsdkDelNet function because
job variable was always initialized as PRL_INVALID_HANDLE
In this patch job variable gets return value of PrlSrv_DeleteVirtualNetwork function()

We need to initialize buflen every time when we get network adapter's
friendly name because we call PrlVmDev_GetFriendlyName in a loop
