The aggregator base class will handle in a thread-safe way all manners of
concurrent flushes, seeks, pad additions and removals, leaving to the
subclass the responsibility of clipping buffers, and aggregating buffers in
the way the implementor sees fit.
It will also take care of event ordering (stream-start, segment, eos).
Basically, a simple implementation will override aggregate, and call
_finish_buffer from inside that function.
