There's no need to call into -parse and -print manually. The
QOM legacy properties do that for us.
Furthermore, in some cases legacy and static properties have exactly
the same behavior, and we could drop the legacy properties right away.
Add an appropriate fallback to prepare for this.

Nice cleanup. Reviewed-by: Anthony Liguori aligu...@us.ibm.com
I wonder how far we are from moving most of qdev-monitor.c to hmp.c and qmp.c
respectively. I think that given this patch, we can actually implement info
qtree/qdm via qom QMP operations.
That would be a fairly nice win.
