First, fix a little crash at the end:

    streamsynchronizer: don't send gap events with huge bogus durations when
advancing EOS streams

    When the input buffers for a stream don't have a duration set,
    timestamp_end might still be GST_CLOCK_TIME_NONE. When advancing
    EOSed streams via GAP events (with other streams not yet EOS), we
    would then use the invalid timestamp_end to calculate the duration
    of the gap. This in turn would make baseaudiosink abort, because it
    would try to allocate memory for a trizillion samples.

    So if buffers don't have a duration set, assume a duration of
    one second for stream catch-up purposes, just so we can still
    continue to catch up in those cases. And make sure that
    timestamp_end is valid before doing calculations with it.
