input: activate legacy kbd

Restores traditional behavior:  Keyboard input will be routed to the most
recently added keyboard.  Without this all kbd input goes to the ps/2
keyboard, even if you add a usb keyboard to your guest.

qdev: Fix bus dependency of DeviceState::hotpluggable getter

Commit 1a37eca107cece3ed454bae29eef0bd1fac4a244 (qdev: add
"hotpluggable" property to Device) added a property "hotpluggable" to
each device, with its getter accessing parent_bus->allow_hotplug.

Add a NULL check.

qdev-monitor: Set properties after parent is assigned in device_add

Test steps:
 (qemu) device_add e1000,addr=adsf
  Property 'e1000.addr' doesn't take value 'adsf'
 (qemu) info qtree
  Then qemu crashed.

Currently we set a link to the new device from its parent bus, but the
device hasn't been added to QOM tree yet. When it fails to set properties,
object_unparent() can't clean up the device.

Delay setting of device properties until the device has been added to
the QOM composition tree. This way, when setting a property fails,
object_unparent() can clean up the device properly.

qom: Avoid leaking str and bool properties on failure

When object_property_add_str() and object_property_add_bool() fail, they
leak their internal StringProperty and BoolProperty structs.  Remember
to free the structs on error.

Luckily this is a low-impact memory leak since most QOM properties are
static qdev properties that will never take the error case.
object_property_add() only fails if the property name is already in use.

Test the error class instead.  Expecting a specific message is

There are no other tests of "desc" as far as I can tell.
