This patch moves qemuDomainTrackJob() as virDomainTrackJob() into
hypervisor because it is called in begin job and end job
functions that will be generalized in the following series.

It does not make sense to propagate virDomainObj and get
qemuDomainObjPrivate from it, when it is already accessible in
the only function qemuDomainObjPreserveJob() is called from. That
being said, we can also propagate virDomainJobObj directly and
avoid using qemu private structure.

We will want to update migration phase without affecting job ownership.
Either in the thread that already owns the job or from an event handler
which only changes the phase (of a job no-one owns) without assuming it.
Let's move the ownership change to a new qemuDomainObjStartJobPhase
helper and let qemuDomainObjSetJobPhase set the phase without touching
ownership.

Recent refactor (v8.1.0-217-ga193f4bef6) generalized job related enums
and functions by changing "qemu" prefix to "vir" and moving them to
src/hypervisor/domain_job.[ch]. This was in most cases a good thing, but
async job phases are driver specific and the corresponding functions
remained in src/qemu/qemu_domainjob.[ch], but still their prefix was
changed to "vir". Let's change it back to "qemu".

These enums are essentially the same and always sorted in the
same order in every hypervisor with jobs. They can be generalized

It does not make sense to have both of these, since one of them
is only a wrapper for the other one. I decided to preserve the
more general one, which requires only virDomainObj and rewrote it
a bit, so that it pulls the qemu driver from privateData.

We only need to set statsType in almost every case of setting
something from private data, so it seems unnecessary to pull
privateData out of current / completed job for just this one
thing every time. I think this patch keeps the code cleaner
without variables used just once.

This patch includes:
* introducing new files: src/hypervisor/domain_job.c and src/hypervisor/domain_job.h
* new struct virDomainJobData, which is almost the same as
qemuDomainJobInfo - the only differences are moving qemu specific
job stats into the qemuDomainJobDataPrivate and adding jobType
(possibly more attributes in the future if needed).
* moving qemuDomainJobStatus to the domain_job.h and renaming it
as virDomainJobStatus
* moving and renaming qemuDomainJobStatusToType
* adding callback struct virDomainJobDataPrivateDataCallbacks
taking care of allocation, copying and freeing of private data
of virDomainJobData
* adding functions for virDomainJobDataPrivateDataCallbacks for
qemu hypervisor
* adding 'public' (public between the different hypervisors) functions
taking care of init, copy, free of virDomainJobData
* renaming every occurrence of qemuDomainJobInfo *info to
virDomainJobData *data

These strings are not constant really. They are allocated in

Historically, we declared pointer type to our types:
typedef struct _virXXX virXXX;
typedef virXXX *virXXXPtr;
But usefulness of such declaration is questionable, at best.
Unfortunately, we can't drop every such declaration - we have to
carry some over, because they are part of public API (e.g.
virDomainPtr). But for internal types - we can do drop them and
use what every other C project uses 'virXXX *'.
This change was generated by a very ugly shell script that
generated sed script which was then called over each file in the
repository. For the shell script refer to the cover letter:

After we started copying the privateData pointer in
qemuDomainObjRestoreJob, we should also free them
once we're done with them.
Register the clear function and use g_auto.
Also add a check for job->cb to qemuDomainObjClearJob,
to prevent freeing an uninitialized job.

Both parsing and formatting of NBD migration jobs is QEMU specific and
since we're trying to create a hypervisor-agnostic module out of
qemu_domainjob.c, move the NBD XML handling bits to the qemu_domain
module instead. Additionally, move the respective NBD XML calls to
the 'parseJob'/'formatJob' callbacks of the
qemuDomainObjPrivateJobCallbacks structure.
