am cdfd5fe2: Fix a typo in Singleton<>

 * (eg: <TYPE>.cpp) to create the static instance of Singleton<>'s attributes,

 * and avoid to have a copy of them in each compilation units Singleton<TYPE>

 * is used.

 * NOTE: we use a version of Mutex ctor that takes a parameter, because

 * for some unknown reason using the default ctor doesn't emit the variable!
