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
Instead of using timerfd, use the context timer-queue to schedule
timeouts. This saves fds and removes some redundant code.
Make the rtp-source timeout and standby code a bit better by using
atomic operations.
Add in input/output stream, setup the talker/listeners.
Implement IEC61883 audio packets, send and receive data.
Implement talker encoding.
With this, audio can be sent and received from MOTU M64.
