Just straight-forward patch.
Use reference counting for privdom as stats internally could drop domain lock.

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.

Because we have no limitation for maximal number of vcpus in containers
we report as maximum 1028 just for the sake of common sence.

In fact, it was never used as far as vz has no features supporting it.
That is why there will be no harm to anyone if we just remove this code to
prevent further misunderstanding and efforts to support dead code.

At the time this code was added we had intentions to support libvirt interface
to manage vz networks. In fact, it was never implemented completely to work
correctly that makes me think that there will be no harm to anyone if we just
rip it off. Moreover, in vz7 we started to use libvirt bridge network driver to
manage networks.

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.

Add the sysfs_prefix argument to the call to allow for setting the
path for tests to something other than SYSFS_CPU_PATH which is a
derivative of SYSFS_SYSTEM_PATH
Use cpupath for nodeCapsInitNUMAFake and remove SYSFS_CPU_PATH
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.

It is better not to assume that newly created network should be
connected to a bridge with same name, but specify it explicitly
by PRL_USE_VNET_NAME_FOR_BRIDGE_NAME flag.

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.
There should be at least one domain for each guest
in cababilities. And in current code we don't add
domain for this guest for example.
if ((guest = virCapabilitiesAddGuest(caps, VIR_DOMAIN_OSTYPE_HVM,
VIR_ARCH_X86_64,
"vz",
NULL, 0, NULL)) == NULL)
Anyway, with two virt types it looks a litte messy, so let's
move adding guest and domain to a separate function.

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.

Function prlsdkGetStatsParam was missing a prototype or the static
keyword. I went with static since it built successfully.
Pushed as a build breaker fix.
Implemented counters:
VIR_DOMAIN_MEMORY_STAT_SWAP_IN
VIR_DOMAIN_MEMORY_STAT_SWAP_OUT
VIR_DOMAIN_MEMORY_STAT_MINOR_FAULT
VIR_DOMAIN_MEMORY_STAT_MAJOR_FAULT
VIR_DOMAIN_MEMORY_STAT_AVAILABLE
VIR_DOMAIN_MEMORY_STAT_ACTUAL_BALLOON
VIR_DOMAIN_MEMORY_STAT_UNUSED
Comments.
1. Use vzDomObjFromDomainRef/virDomainObjEndAPI pair to get domain
object as we use prlsdkGetStatsParam. See previous statistics
comments.
2. Balloon statistics is not applicable to containers. Fault
statistics for containers not provided in PCS6 yet.

Use vzDomObjFromDomainRef/virDomainObjEndAPI pair to get domain
object as we use prlsdkGetStatsParam that can release domain
object lock and thus we need a reference in case domain
is deleated meanwhile.

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()
This patch moves all src/parallels/parallels* files to vz/vz*
and fixes build accordingly.
No functional changes.
