[PATCH v1 06/18] sink, source: Support creating suspended sinks and sources

[mikel.astiz.oss@xxxxxxxxx (Mikel Astiz)]

From: Mikel Astiz <mikel.astiz@xxxxxxxxxxxx>

The initial state of a sink or source might not necessarily be IDLE,
because sometimes it might be suspended from the very beginning.
