Reinstate the trackerid handling correctly #84

Closed jlouis closed 13 years ago

Trackers can return a trackerid blurb which essentially must be sent back to the tracker on subsequent requests. We did not honor this at all, so it got deleted. But it should not be too hard to reestablish.

This has been analyzed, and I've chosen to skip it for now:

The original BitTorrent protocol spec, BEP 3, does not mention it at all.
It is not clear what it is used for at the tracker level
There is no specification on how to make it interplay with UDP tracking (BEP 15).
There is no specification on how to make it interplay with the multiple-tracker extension (BEP 12).

In other words, any implementation of this would probably not do the same thing as other clients are doing.
