Pull request description:
This patch removes support in Bitcoin Core for Tor v2 onions, which are already removed from the release of Tor 0.4.6.
- no longer serialize/deserialize and relay Tor v2 addresses
- ignore incoming Tor v2 addresses
- remove Tor v2 addresses from the addrman and peers.dat on node launch
- update generate-seeds.py to ignore Tor v2 addresses
- remove Tor v2 hard-coded seeds
Tested with tor-0.4.6.1-alpha (no v2 support) and 0.4.5.7 (v2 support). With the latest Tor (no v2 support), this removes all the warnings like those reported with current master in https://github.com/bitcoin/bitcoin/issues/21351
```
<bitcoind debug log>
Socks5() connect to […].onion:8333 failed: general failure
<tor log>
Invalid hostname [scrubbed]; rejecting
```
and the addrman no longer has Tor v2 addresses on launching bitcoind.
```rake
$ ./src/bitcoin-cli -addrinfo
{
"addresses_known": {
"ipv4": 44483,
"ipv6": 8467,
"torv2": 0,
"torv3": 2296,
"i2p": 6,
"total": 55252
}
}
```
After recompiling back to current master and restarting with either of the two Tor versions (0.4.5.7 or 0.4.6.1), -addrinfo initially returns 0 Tor v2 addresses and then begins finding them again.
Ran nodes on this patch over the past week on mainnet/testnet/signet/regtest after building with DEBUG_ADDRMAN.
Verified that this patch bootstraps an onlynet=onion node from the Tor v3 hardcoded fixed seeds on mainnet and testnet and connects to blocks and v3 onion peers: `rm ~/.bitcoin/testnet3/peers.dat ; ./src/bitcoind -testnet -dnsseed=0 -onlynet=onion`
Tested using `addnode`, `getaddednodeinfo`,`addpeeraddress`, `disconnectnode` and `-addrinfo` that a currently valid, connectable Tor v2 peer can no longer be added:
Thanks to Vasil Dimov, Carl Dong, and Wladimir J. van der Laan for their work on BIP155 and Tor v3 that got us here.
