c8238579fb lib: Drop internal virXXXPtr typedefs
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:

c21f066d61 qemu_conf: properly set 'deprecation_behavior' default value
The comment for that option states that the default value is 'none' but
it was not set by the code. By default the value is NULL which results
into the following warning:

warning : qemuBuildCompatDeprecatedCommandLine:10393 : Unsupported deprecation behavior '(null)' for VM 'test'

b4d0207906 qemuBlockJobProcessEventCompletedPull: Add backingStore terminators if base is NULL
When doing a blockpull with NULL base the full contents of the disk are
pulled into the topmost image which then becomes fully self-contained.

qemuBlockJobProcessEventCompletedPull doesn't install the backing chain
terminators though, although it's guaranteed that there will be no
backing chain behind disk->src.

Add the terminators for completness and for disabling backing chain
detection on further boots.

46e748aa02 qemuBlockJobProcessEventCompletedPull: Avoid dangling pointer after blockpull
When doing a full block pull job (base == NULL) and the config XML
contains a compatible disk, the completer function would leave a
dangling pointer in 'cfgdisk->src->backingStore' as cfgdisk->src would
be set to the value of 'cfgbase' which was always set to
'cfgdisk->src->backingStore'.

This is wrong though since for the live definition XML we set the
respective counterpart to 'job->data.pull.base' which is NULL in the
above scenario.

This leads to a invalid pointer read when saving the config XML and may
end up in a crash.

Resolve it by setting 'cfgbase' only when 'job->data.pull.base' is
non-NULL.

b3605a4d83 nodedev: Only set up mdevctl monitors if mdevctl.d exist
During its initialization, the nodedev driver tries to set up
monitors for /etc/mdevctl.d directory, so that it can register
mdevs as they come and go. However, if the file doesn't exist
there is nothing to monitor and therefore we can exit early. In
fact, we have to otherwise monitorFileRecursively() fails and
whole driver initialization fails with it.

e65d4917a4 nodedev: Don't join not spawned threads
During the nodedev driver initialization two threads are created:
one for listening on udev events (like device plug/unplug) and
the other for enumerating devices (so that the main thread doing
the driver init is not blocked). If something goes wrong at any
point then nodeStateCleanup() is called which joins those two
threads (possibly) created before. But it tries to join them even
they weren't created which is undefined behaviour (and it just so
happens that it crashes on my system).

If those two virThread variables are turned into pointers then we
can use comparison against NULL to detect whether threads were
created.

3d3435e395 nodedev: Lock @priv sooner
The nodedev driver private data object @priv is created by
calling udevEventDataNew(). After that, driver->privateData
pointer is set to the freshly allocated object and only a few
lines after all of this the object is locked. Technically it is
safe because there should not be any other thread at this point,
but defensive style of programming says it's better if the object
is locked before driver's privateData is set.
