qdev: Fix "info qtree" to show links
qdev_print_props() retrieves a property's value from its legacy
property if it exists. A legacy property is created by
qdev_class_add_legacy_property() when the property has a print()
method or does not have a get() method.
If it has a print() method, the legacy property's value is obtained
from the property's print() method. This is used to format PCI
addresses nicely, i.e. like 01.3 instead of 11.
Else, if doesn't have a get() method, the legacy property is
unreadable. "info qtree" silently skips unreadable properties.
Link properties don't have a get() method, and are therefore skipped.
This is wrong, because the underlying QOM property *is* readable.
Change qdev_print_props() to simply use a print() method directly if
it exists, else get the value via QOM.
"info qtree" now shows links fine. For instance, machine "pc" onboard
device "PIIX4_PM" property "bus" is now visible.

qdev: Legacy properties are now unused internally, drop
Legacy properties are an accidental and undocumented external
interface. qom-set doesn't work for them (no .set() method). qom-get
and qom-list-get work only when the underlying qdev property has a
.print() method, i.e. the PCI address properties, as explained in the
previous commit. Here's one that works:
(qemu) qom-get /machine/unattached/device[3]/pm addr
11
(qemu) qom-get /machine/unattached/device[3]/pm legacy-addr
"01.3"
And here's one that doesn't:
(qemu) qom-get /machine/unattached/device[3]/pm bus
"/machine/i440fx/pci.0"
(qemu) qom-get /machine/unattached/device[3]/pm legacy-bus
Error: Property 'PIIX4_PM.legacy-bus' is not readable
Actual use of this undocumented interface seems quite unlikely. A
deprecation period seems unnecessary. Drop it.

monitor/qmp: cleanup SocketChardev listener sources early to avoid fd
handling race
When starting a dummy QEMU process with virsh version, monitor_init_qmp()
enables IOThread monitoring of the QMP fd by default. However, a race
condition exists during the initialization phase: the IOThread only removes
the main thread's fd watch when it reaches
qio_net_listener_set_client_func_full(),
which may be delayed under high system load.
This creates a window between monitor_qmp_setup_handlers_bh() and
qio_net_listener_set_client_func_full() where both the main thread and
IOThread are simultaneously monitoring the same fd and processing events.
This race can cause either the main thread or the IOThread to hang and
become unresponsive.
Fix this by proactively cleaning up the listener's IO sources in
monitor_init_qmp() before the IOThread initializes QMP monitoring,
ensuring exclusive fd ownership and eliminating the race condition.
