The source project of this merge request has been removed.
Fail if name is already claimed
Make request_name fail if the DBus server replies with Exists, that is, if the requested name is already owned by someone else.
Also remove ReplaceExisting from the set of passed flags, because this method doesn't specify AllowReplacement either. Hence ReplaceExisting is somewhat redundant within the scope of request_names: For it to make any difference callers would have to bypass request_name and directly use DBusProxy::request_name anyway, in order to pass AllowReplacement, and at this point they can also manually pass ReplaceExisting anyway.
Closes #199 (closed)
