Now we check disk parameters correctness in DomainPostParse.

As far as Virtuozzo6 and Virtuozzo7 support different disk types for virtual
machines (ploop and qcow2 respectively) and different buses (vz6: IDE, SCSI,
SATA; vz7: IDE SCSI) we add vzCapabilities structure to help undestand which
disk formats and buses are supported in the context of a current connection.

When a new connection opens, we select proper capabilities in accordance to
current Virtuozzo version.

Move code from connectGetVersion callback to vzInitVersion function

The problem with the original virLogParseOutputs method was that the way it
parsed the input, walking the string char by char and using absolute jumps
depending on the virLogDestination type, was rather complicated to read.
This patch utilizes virStringSplit method twice, first time to filter out any
spaces and split the input to individual log outputs and then for each
individual output to tokenize it by to the parts according to our
PRIORITY:DESTINATION?(:DATA) format. Also, to STREQLEN for matching destination
was replaced with virDestinationTypeFromString call.

In order to refactor the ugly virLogParseOutputs method, this is a neat way of
finding out whether the destination type (in the form of a string) user
provided is a valid one. As a bonus, if it turns out it is valid, we get the
actual enum which will later be passed to any of virLogAddOutput methods right
away.

Test for parser's functionality.

Patch adds a generic DO_TEST_FULL macro, some PASS/FAIL macros to better
visually distinguish tests that should fail and tests that should pass. Also,
some cosmetic changes like renames and direct call to fprintf is replaced with
our VIR_TEST_DEBUG macro, as using testutils should be our preferred way of
reporting errors in tests.

Just a cleanup I stumbled upon in one of my older branches I did when
browsing through some code and forgot to send it.

In qemuConnectDomainXMLToNative() we set up the monitor, but we never
memset() it to zeros.  Thanks to the introduction of the logfile
parameter of chardevs (and the logfile member of the struct), we started
checking whether that's non-NULL and that exposed this old error.

These functions already report fine grained errors, there's no
benefit to overwriting the error here.

Reverting to a snapshot may change domain configuration. New
configuration should be saved if domain has persistent flag.

VIR_DOMAIN_EVENT_DEFINED_FROM_SNAPSHOT is emitted in case of
configuration update.

VIR_DOMAIN_EVENT_DEFINED_FROM_SNAPSHOT event should be emitted
when domain configuration was changed on revert to snapshot.

These comments explain the difference between a virPCIDevice
instance used for lookups and an actual device instance; some
information is also provided for specific uses.

This is not just a cosmetic change: the name of the variable now
gives a hint about what it is supposed to be used for.

virHostdevGetPCIHostDeviceList() is similar but does not filter out
devices that are not in the active list; that said, we are looking
up the device in the active list just a few lines after anyway, so
we might as well just keep a single function around.

This also helps stress the fact the objects contained in pcidevs are
only for looking up the actual devices, which is something later
commits will make even more explicit.

The docs claims the cache attribute of the disk <driver>
element supports 'default' as one of its permissible values,
but such configuration fails virt-xml-validate. Add 'default'
as one of the cache attribute choices in domaincommon.rng.

Acronyms should be written in all caps.

We're in the hostdev module, so mgr is not an ambiguous name, and
in fact it's already used in some cases. Switch all the code over.

Take the chance to shorten declaration of
virHostdevIsPCINodeDeviceUsedData structures.

When we want to look up a device in a device list and we already
have the IDs from another source, we can simply use
virPCIDeviceListFindByIDs() instead of creating a temporary device
object.

The new order aligns better with the virHostdev prefix.

The only possible return values are true and false, so the return
type should be bool instead of int.

If 'last_processed_hostdev_vf != -1' is false then, since the
loop counter 'i' starts at 0, 'i <= last_processed_hostdev_vf'
can't possibly be true and the loop body will never be executed.

However, since 'i' is unsigned and 'last_processed_hostdev_vf'
is signed, we can't just get rid of the check completely; what
we can do is move it outside of the loop to avoid checking its
value on every iteration and cluttering the actual loop
condition.

Since commit 9c14a9ab we have broken active domain listing
because reworked prlsdkLoadDomain doesn't set dom->def->id
propely. It just looses it when a new def structure is set.
Now we make prlsdkConvertDomainState function return void
and move calling it after an old dom->def is replaces with
a new one within prlsdkLoadDomain function.

This function can be called over a domain definition that has no
video configured. The
tests/qemuxml2argvdata/qemuxml2argv-minimal.xml file could serve
as an example. Problem is, before the check that domain has some
or none video configured, def->videos is dereferenced causing a
segmentation fault in case there's none video configured.
