module-avb: Introduce changes in the mechanisms how the stream are
built: * es_builder: create stream with state variables and counters * acmp: do not use the stream list, go through the descriptor to find the index * stream: do not store redundant information such as the index and descriptor * internal: removing the stream server and function associated to it module-avb: internal, stream: removing server_find_stream
