Jouni Malinen dc39004318 WPS: Remove unused WEP related functionality 
Now that WPS 2.0 support is enabled unconditionally, WEP and Shared auth
type are not allowed. This made some of the older code unused and that
can now be removed to clean up the implementation. There is still one
place where WEP is allowed for testing purposes: wpa_supplicant as
Registrar trying to configure an AP to use WEP. That is now only allowed
in CONFIG_TESTING_OPTIONS=y builds, though.

* NameOwnerChanged handling
*
* Some services we provide allow an application to register for
* a signal that it needs. While it can also unregister, we must
* be prepared for the case where the application simply crashes
* and thus doesn't clean up properly. The way to handle this in
* DBus is to register for the NameOwnerChanged signal which will
* signal an owner change to NULL if the peer closes the socket
* for whatever reason.
*
* Handle this signal via a filter function whenever necessary.
* The code below also handles refcounting in case in the future
* there will be multiple instances of this subscription scheme.
