Introduce guest agent specific job categories to allow threads to
run agent monitor specific jobs while normal monitor jobs can
also be running.

Alter _qemuDomainJobObj in order to duplicate certain fields that
will be used for guest agent specific tasks to increase
concurrency and throughput and reduce serialization.

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 f0a23c0c.

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"

was generated when trying to hotplug an IOThread to a domain since
qemuDomainHotplugAddIOThread passes a NULL arglist.

freed not only the chardev from domain but also the one from

introduced virDomainDetachDeviceAlias() they became the same

In addition to making the configuration more consistent, this

divided into four steps, some of which have slightly different
semantics and the relationship between which is not immediately
obvious without consulting the documentation, to a single

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.
