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.

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.

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.
