This element is a little different from the one in bug 641024, because the
incoming and outgoing streams are intended to conform to the same segment --
hence, the initial gap in addition to the timestamp remapping.  This is
intended to make it possible to send one stream and its delayed counterpart
into an adder.

I could add a boolean property (true by default) to turn on or off the initial
gap buffer, thus optionally providing the behavior of bug 641024.

I agree that this is more properly thought of as a timestamp shift; the "delay
line" part would really be any queue that followed this element.  I still
prefer the name "audiodelay" because in a pipeline where this element is used
it will have the effect of causing the non-silence part of the signal to be
played back at a later time.  How about "audiotimestampshift" or
"audiotimestampoffset" as alternative names?.
