I2P Only Mode

[OvercookedBeef]

From qbittorrent/qBittorrent#19913

Suggestion

libtorrent supports I2P, but it currently only uses I2P for torrents with I2P trackers. My suggestion is a mode that uses I2P for every torrent. I2P has outproxy support so it won't just fail on a regular torrent.

Use case

I2P only mode would ensure that no traffic went outside of I2P. This means that people without a VPN can add torrents without worry of leaking, similar to the network interface option.

BiglyBT uses DHT over I2P, so it must be possible.

This feature does not require DHT, as stated in the issue I2P supports out proxies. I2P DHT is a lot more work that it seems like libtorrent won't support any time soon: #7408

Either way, even if it didn't support outproxies, one of the main reasons I want this is to prevent leaks, which has already happened to me when I thought a torrent was going to go through I2P but didn't.

libtorrent currently talks to i2p via the SAM protocol. Does this protocol support ways of contacting plain IPs and ports and speak arbitrary protocols?
