VMs with hardcoded platform network devices are forced to use old
style '-net nic' command line config. Current we use qemu's vlan
option to hook this with the '-netdev' host side of things.
However since qemu 1.2 there is '-net nic,netdev=X' option for
explicitly referencing a netdev ID, which is more inline with
typical VM commandlines, so let's switch to that

There are two sets of functions here:
1) some functions talk on both monitor and agent monitor,
2) some functions only talk on agent monitor.
For functions from set 1) we need to use

need to use qemuDomainObjBeginAgentJob() only.

The point is to break QEMU_JOB_* into smaller pieces which

are two threads, one is trying to query something on qemu
monitor while the other is trying to query something on agent
monitor these two threads would serialize. There is not much

If there's a long running job it might cause us to wait 30
seconds before we give up acquiring the job. This is problematic
to interactive applications that fetch stats repeatedly every few
seconds.
The solution is to introduce
VIR_CONNECT_GET_ALL_DOMAINS_STATS_NOWAIT flag which tries to
acquire job but does not wait if acquiring failed.

The aim of this API is to allow the caller to do best effort.
Some functions can work even when acquiring the job fails (e.g.

delay if they have to wait up to 30 seconds for each domain that
is processing some other job.

Fix the return value status comparison checking for call to
virJSONValueObjectCreateVArgs introduced by commit id f0a23c0c3.
If a NULL arglist is passed, then a 0 is returned which is a
valid status and we only should fail when the return is < 0.
This resolves an issue seen for "virsh iothreadadd $dom $iothread"
where a "error: An error occurred, but the cause is unknown" error
was generated when trying to hotplug an IOThread to a domain since
qemuDomainHotplugAddIOThread passes a NULL arglist.

We only formatted the <sev> element when QEMU supported the feature when
in fact we should always format the element to make clear that libvirt
knows about the feature and the fact whether it is or isn't supported
depends on QEMU version, in other words if QEMU doesn't support the
feature we're going to format the following into the domain capabilities

xenParseVif() does a lot of stuff and, in order to make things cleaner,
let's split it in two new functions:
- xenParseVif(): it's a new function that keeps the old name. It's
responsible for the whole per-Vif logic from the old xenParseVif();
- xenParseVifList(): it's basically the old xenParsePCI(), but now it
just iterates over the list of Vifs, calling xenParsePCI() per each Vif.
This patch is basically preparing the ground for the future when
typesafe virConf acessors will be used.
