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.
qemuConnectGetAllDomainStats()). But what they can't bear is
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.

Commit aad3a0b5f altered virObjectEventStateQueueRemote to move
the "if (!event) return" call added in the previous commit 031eb8f6
to virObjectEventStateQueue. Neither commit altered the function
prototype which used ATTRIBUTE_NONNULL(2).
This caused Coverity build problems. Since @event is now checked,
just remove the ATTRIBUTE_NONNULL check from both prototypes.

For reasons I don't understand my original patch of 75f0fd5112
freed not only the chardev from domain but also the one from
passed virDomainDeviceDefPtr. This caused no troubles until now,
because those two pointers were separate, but after I've
introduced virDomainDetachDeviceAlias() they became the same
resulting in double free on detach.

It mirrors the existing DOCKER_CMD, both in how it's defined
as part of the environment and how it's called by passing it
directly to the shell.
In addition to making the configuration more consistent, this
also allows us to move from having the macOS build script
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
straightforward shell invocation.

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.

typesafe virConf acessors will be used.
