Similarly to the DEVICE_DELETED event we will be able to tell when
unplug of certain device types will be rejected by the guest OS. Wire up
the device deletion signalling code to allow handling this.

No need to keep two separate conditions. A slight juggling of return
values is needed to accomodate virDomainObjWaitUntil.

Neither of the callers cares whether the DEVICE_DELETED event isn't
supported or the event was received. Simplify the code and callers by
unifying the two values and changing the return value constants so that
a temporary variable can be omitted.

Callers ignore if this function returns -1 and continue as though the
DEVICE_DELETED event was not received. Since we can't be sure that the
event was not received we should behave as if the event was not
supported and remove the device definition right away. The error
fortunately won't really happen here.

The address assigning code might add new pci bridges.
We need them to have an alias when building the command line.

In real word usage, this is not a problem because all the code
paths already call qemuDomainAssignAddresses. However moving
this call lets us remove one extra call from qemuxml2argvtest.

Essentially revert commit 3a6204cb which added these to allow the test
suite to pass without depending on the host system state.

Since commit 4b527c1a we already mock virSCSIDeviceGetSgName, so these
callbacks are useless.

Instead of calling the virDomainGraphicsListensParseXML function for all
graphics types and ignore the wrong ones move the call only to graphics
types where we supports listen elements.

Those are the last two places that uses the getter functions.  Use a
direct access instead and remove those getters.

Removes the check for graphics type, it's not a public API and developer
know what he's doing and this check makes no sense.  It also removes
the ability to allocate a new array if there is none.  This was used by
the virDomainGraphicsListenAdd* functions and isn't used anymore.

This is now a simple getter with simple check for listens array presence
and whether the index in out of bounds.

This effectively removes virDomainGraphicsListenSetAddress which was
used only to change the address of listen structure and possible change
the listen type.  The new function will auto-expand the listens array
and append a new listen.

The old function was used on pre-allocated array of listens and in most
cases it only "add" a new listen.  The two remaining uses can access the
listen structure directly.

Now that the mirror parsing code is not crammed in the main disk parser
we can employ better coding style.

Changes are indentation and 'cleanup' label instead of 'error'.

Rest of the fields of the iotune data structure did not check for
malformed integers. Use the previously defined macro to extract them
which will simplify the code and add error reporting.

Since the structure was pre-initialized to 0 we don't need to set every
single member to 0 if it's not present in the XML. Additionally if we
put the name of the field into the error message the code can be
simplified using a macro to parse the members.

Since this function isn't doing any cleanup, the label is not necessary.

Also simplify the code by switching to a for loop.

All the fields were initialized to 0.

No need to remember connection name and have corresponding
domain type to keep backward compatibility with former
'parallels' driver. It is enough to be able to accept 'parallels'
uri and domain types.

Return early if there is nothing to do.

If we encounter a video device with primary=yes, we insert it
at def->videos[0].

There is no need to record this in a separate variable,
just check if there already is a primary video at def->videos[0].

We call VIR_INSERT_ELEMENT_INPLACE either with 0 (for primary video)
or def->nvideos (for the rest).

Use a variable with more semantic name, since j is usually used
for iterating.

We start with both i and def->nvideos at 0 and increment both
after every successful iteration.

Use i directly, instead of passing the def->nvideos value through j.

Commit 119cd06e started setting the primary bool for the first
user-specified video even if user omitted the 'primary' attribute.

However this was done before the addition of the implicit device.
This broke startup of transient qemu domains with no <video>:
https://bugzilla.redhat.com/show_bug.cgi?id=1325757

Move this default to virDomainDefPostParseInternal,
after the addition of the implicit video device, to catch the implicit
video as well.

Separate parsing of the XML from auto-generating the device.

Quite straigthforward as vz sdk memory setting function makes
just what we want to that is set "amount of physical memory
allocated to a domain".

'useflags' is introduced for non flag function implementation.
We can't just use combination of flags like "live | config" or
we fail for inactive domains. Other combinations have drawbacks
too.

Actually this is not pure refactoring. Part of common code is
replaced with virDomainObjUpdateModificationImpact and this
a good replacement. It includes removed check of inactive
domain and active flags set. Additionally we resolve
current flag in accordance with current state of domain.
Thus it becames possible to attach/detach devices for
inactive domains if this flag is set.

Commit dc98a5bc refactored the code a lot and forget about checking if
listen attribute is specified.  This ensures that listen attribute and
first listen element are compared only if both exist.
