[PATCH 0/4] MR10417: winebth.sys: Handle BlueZ crashes and restarts, only make calls to BlueZ if it is available.

[Vibhav Pant (＠vibhavp)]

* Only start initial object enumeration if GetNameOwner succeeds for `org.bluez` (i.e, BlueZ is up).
* Listen for the `NameOwnerChanged` signal on the system bus, this happens when:
  * BlueZ shuts down/crashes: In this case, we emit a `BLUETOOTH_WATCHER_EVENT_TYPE_SERVICE_DOWN`, which removes all added radios/devices/services from the PE driver.
  * BlueZ starts, here we perform an initial enumeration of objects, and register the authentication agent with BlueZ.
