cb1721767b qemu: monitor: Remove legacy 'device_add' infrastrcture
Remove the old-style 'device_add' helpers which parse the commandline
arguments to JSON since we now coverted all usage to use JSON directly.

2154718c29 qemu: Rename 'qemuMonitorAddDeviceArgs' to 'qemuMonitorAddDeviceProps'
We commonly use 'props' for the JSON object describing something. Rename
the monitor device addition code.

Additionally the common approach is to clear the pointer if it was
consumed so the arguments are adjusted to do so.

5c2d6908a6 qemu: Refresh the current size of virtio-mem on monitor reconnect
If the QEMU driver restarts it loses the track of the current size
of virtio-mem (because it's runtime type of information and thus
not stored in XML) and therefore, we have to refresh it when
reconnecting to the domain monitor.

9985f62b51 qemu: Wire up MEMORY_DEVICE_SIZE_CHANGE event
As advertised in previous commit, this event is delivered to us
when virtio-mem module changes the allocation inside the guest.
It comes with one attribute - size - which holds the new size of
the virtio-mem (well, allocated size), in bytes.
Mind you, this is not necessarily the same number as 'requested
size'. It almost certainly will be when sizing the memory up, but
it might not be when sizing the memory down - the guest kernel
might be unable to free some blocks.

This current size is reported in the domain XML as an output
element only.

3ec559661a qemu: Wire up <memory/> live update
As advertised in one of previous commits, we want to be able to
change 'requested-size' attribute of virtio-mem on the fly. This
commit does exactly that. Changing anything else is checked for
and forbidden.

Once guest has changed the allocation, QEMU emits an event which
we will use to track the allocation. In the next commit.

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:
