Add stream_setup_socket and stream_send ops to avb_transport_ops so the
stream data plane can use the same pluggable transport backend as the
control plane. Move the raw AF_PACKET socket setup from stream.c into
avdecc.c as raw_stream_setup_socket(), and add a raw_stream_send()
wrapper around sendmsg().
Add a stream list (spa_list) to struct server so streams can be iterated
after creation, and add stream_activate_virtual() for lightweight
activation without MRP/MAAP network operations.
Implement loopback stream ops: eventfd-based dummy sockets and no-op
send that discards audio data. This enables virtual AVB nodes that work
without network hardware or privileges.

Introduce struct avb_transport_ops vtable with setup/send_packet/
make_socket/destroy callbacks. The existing raw AF_PACKET socket code
becomes the default "raw" transport. avdecc_server_new() defaults to
avb_transport_raw if no transport is set, and avdecc_server_free()
delegates cleanup through the transport ops.
This enables alternative transports (e.g. loopback for testing) without
modifying protocol handler code.

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.
