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.

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.
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.

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 119cd06 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.
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.

Replace the nonsensical debug statement by adding the expected event
code into the existing debug statement.
Since the monitor code always notifies the agent on guest
reboot/shutdown even if that was not initiated by the agent the warning
emitted later is bogus and pollutes the logs in such cases. Delete it
and keep just the original debug message where this info can be
inferred.

Some places already check for "virt-" prefix as well as plain "virt".
virQEMUCapsHasPCIMultiBus did not, resulting in multiple PCI devices
having assigned the same unnumbered "pci" alias.
Add a test for the "virt-2.6" machine type which also omits the
<model type='virtio'/> in <interface>, to check if
qemuDomainDefaultNetModel works too.

FreeBSD lacks ENODATA, and viruuid.c redefines it to EIO, but it's not
actually using it. On the other hand, we have virrandom.c that's using
ENODATA. So make this re-definition common by moving it to internal.h,
so all the current and possible future users don't need to care about
that.
In the latest libxenlight code, libxl_domain_create_restore accepts a
new argument. Update libvirt's libxl driver for that. Use the macro
provided by libxenlight to detect which version should be used.
The new parameter (send_back_fd) is set to -1 because libvirt provides
no such fd.

Our use of gnutls_rnd(), introduced with commit ad7520e8, is
conditional to the availability of the <gnutls/crypto.h> header
file.
Such check, however, turns out not to be strict enough, as there
are some versions of GnuTLS (eg. 2.8.5 from CentOS 6) that provide
the header file, but not the function itself, which was introduced
only in GnuTLS 2.12.0.
Introduce an explicit check for the function.
As usual we try to deal correctly with vz domains that were
created by other means and thus can have all range of SDK domain
parameters. If vz domain boot order can't be represented
in libvirt os boot section let's give warning and make os boot section
represent SDK to some extent.
1. Os boot section supports up to 4 boot devices. Here we just
cut SDK boot order up to this limit. Not too bad.
2. If there is a floppy in boot order let's just skip it.
Anyway we don't show it in the xml. Not too bad too.
3. SDK boot order with unsupported disks order. Say we have "hdb, hda" in
SDK. We can not present this thru os boot order. Well let's just
give warning but leave double <boot dev='hd'/> in xml. It's
kind of misleading but we warn you!
SDK boot order have an extra parameters 'inUse' and 'sequenceIndex'
which makes our task more complicated. In realitly however 'inUse'
is always on and 'sequenceIndex' is not less than 'boot position index'
which simplifies out task back again! To be on a safe side let's explicitly
check for this conditions!
We have another exercise here. We want to check for unrepresentable
condition 3 (see above). The tricky part is that in contrast to
domains defined thru this driver 3-rd party defined domains can
have device ordering different from default. Thus we need
some id to check that N-th boot disk of os boot section is same as
N-th boot disk of SDK boot. This is what prlsdkBootOrderCheck
for. It uses disks sources paths as id for disks and iface names
for network devices.

The patch makes some refactoring of the existing code. Current boot order spec code
makes very simple thing in somewhat obscure way. In case of VMs
it sets the first hdd as the only bootable device. In case of CTs it
doesn't touch the boot order at all if one of the filesystems is mounted to root.
Otherwise like in case of VMs it sets the first hdd as the only bootable
device and additionally sets this device mount point to root. Refactored
code makes all this explicit.
The actual boot order support is simple. Common libvirt domain xml parsing
code makes the exact ordering of disks devices as described in docs
for boot ordering (disks are sorted by bus order first, device target
second. Bus order is the order of disk buses appearence in original
xml. Device targets order is alphabetical). We add devices in the
same order and SDK designates device indexes sequentially for each
device type. Thus device index is equal to its boot index. For
example N-th cdrom in boot specification refers to sdk cdrom with
it's device index N.
If there is no boot spec in xml the parsing code will add <boot dev='hdd'>
for HVMs automatically and we backward compatibly set fist hdd as
bootable.
