We also want to directly support deserialization of TokenBuffer. 

Note that we use scalar deserializer base just because we claim
to be of scalar for type information inclusion purposes; actual
underlying content can be of any (Object, Array, scalar) type.
 Since 2.3, another important thing is that possible native ids (type id, object id) should be properly copied even when converting with TokenBuffer. Such ids are supported if (and only if!) source JsonParser supports them. /**
