Add a build-event streamer class

The BuildEventStreamer will listen for BuildEvents and stream them
to the provided transports. It also ensures events are properly chained:
for unsolicited events, it will add progress events to chain them and
at the end of a build it closes all announced but not produced events
as aborted.
