Subject: [PATCH 8/8] Add "GetConnectionSmackContext" D-Bus daemon method

This method is used to obtain smack label of given D-Bus client.
Note that it is deprecated and is included only for compatilibity with
existing D-Bus users. GetConnectionCredentials should be used to obtain
client's credentials.
