'HotplugHandler.unplug' callback is currently used as async
call to issue unplug request for device that implements it.
Renaming 'unplug' callback to 'unplug_request' should help to
avoid confusion about what callback does and would allow to
introduce 'unplug' callback that would perform actual device
removal when guest is ready for it.

hw/pcie: better hotplug/hotunplug support

The current code is broken: it does surprise removal which crashes guests.

Reimplemented the steps:
- Hotplug triggers both 'present detect change' and
'attention button pressed'.

- Hotunplug starts by triggering 'attention button pressed',
then waits for the OS to power off the device and only
then detaches it.

Fixes CVE-2014-3471.

qdev: Drop misleading qdev_free() function

The qdev_free() function name is misleading since all the function does
is unlink the device from its parent. The device is not necessarily
freed.

The device will be freed when its QObject refcount reaches zero. It is
usual for the parent (bus) to hold the final reference but there are
cases where something else holds a reference so "free" is a misleading
name.

Call object_unparent(obj) directly instead of having a qdev wrapper
function.
