BitTorrent v2 protocol & SHA256 via libtorrent 2.0.x series

[teddyrogers]

Tribler 8.0.7, does not support BitTorrent v2 protocol. Attempting to import a v2 SHA256 magnet link gives error:

Error: Failed to retrieve metadata! Error while getting an infohash from magnet: RuntimeError: missing info-hash from URI [libtorrent:22]

Additionally importing a v2 .torrent shows, under the "Size" column, the value "NaN B". Proceeding with the download gives the error message, "Failed to start download!"

Please support the more secure v2 protocol with stronger SHA256 hashing algorithm. This will also reduce the likelihood of MITM attacks within Tribler network. BitTorrent v2 can be implemented via libtorrent 2.0.x series.

Noted, specifically this is to capture implementation of the v2 protocol and SHA256.
