* perf: use scrape to know when a swarm is all-seeds For private torrents, the tracker is the sole source of peers. So when a private torrent's tracker responds that there are 0 leechers, we can use that information to mark the entire swarm as seeders and to not initiate connections to those peers if we are seeding. This can help seedboxes to more efficiently pick which swarms to prioritize. This strategy is not used on public torrents, since new seeder-to-seeder connections can be useful there for pex. This PR changes tr_peerMgrAddPex() to (1) remove tr_atom.seedProbability field (which was not as robust as intended) and (2) add batches of peers instead of a single peer. * fix: only use all-seeds check for private torrents
