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.

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.

VIR_SOCKET_ADDR_VALID dereferences the pointer, thus if we pass NULL
into virNetDevSetIPAddress it crashes. Regression introduced by
b3d06987.

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.

virSocketAddrFormat() wants a single pointer, not a double pointer.

Fixes the following compilation error on FreeBSD:

   'virSocketAddr **' to parameter of type 'const virSocketAddr *';
   remove & [-Werror,-Wincompatible-pointer-types]
      if (VIR_SOCKET_ADDR_VALID(peer) && !(peerstr = virSocketAddrFormat(&peer)))
                                                                         ^~~~~

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.
