Proposed patch

In streams with elements that have broken or dishonest position queries, the
progressreport element can produce confusing output.

The attached patch adds a mode in which the position is determined by looking
at the buffer metadata, without doing any queries.  Of course, this only works
for FORMAT_TIME.  In a slightly fancier version of this patch, duration could
be taken from the configured segment.
