[pulseaudio-discuss] [PATCH v2 00/18] Add a basic node concept

[Tanu Kaskinen]

This patch set adds the pa_node struct to the core, extends alsa,
bluetooth, jack and native-protocol ports, sinks, sources, sink-inputs
and source-outputs so that they implement nodes, and adds
introspection and pactl list support for nodes.

Changes in v2:
 - There are no more pa_port_node, pa_sink_node etc. structs. If there
   is need to have e.g. port node specific code, it will probably go
   to device-port.c.
 - Sinks and sources aren't required to have the
   PA_PROP_DEVICE_DESCRIPTION property set.
   pa_sink/source_get_description() handles missing descriptions by
   returning the sink/source name as a fallback.
 - The device class stuff is not included in this patch set anymore.
   It will possibly come back in the next patch set. As a result, the
   node names aren't very informative at this stage.
 - pa_node doesn't have the "persistent" field anymore. It's not
   needed at this point, and it can be added later.
 - Added protocol support and pactl list support for nodes.
 - Some patches of v1 have been merged already.
