module-avb: Introduce changes in the mechanisms how the stream are

Browse source 
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
