libevent seems to have invaded `libbitcoin_common` via `url.cpp`

`url.cpp` is used only from `test/fuzz/string.cpp` and `wallet/rpcwallet.cpp`

libevent should only be required for bitcoind, bitcoin-cli and (due only to the hack of passing wallet names) bitcoin-qt

                throw JSONRPCError(RPC_MISC_ERROR, errors[0]);
                break;
        }
    }
    UniValue result(UniValue::VOBJ);
    
    
    if (!pwallet->IsWalletFlagSet(WALLET_FLAG_DISABLE_PRIVATE_KEYS)) {
        if (!feebumper::SignTransaction(*pwallet, mtx)) {
            throw JSONRPCError(RPC_WALLET_ERROR, "Can't sign transaction.");
        }
        uint256 txid;
        if (feebumper::CommitTransaction(*pwallet, hash, std::move(mtx), errors, txid) != feebumper::Result::OK) {
            throw JSONRPCError(RPC_WALLET_ERROR, errors[0]);
        }
        result.pushKV("txid", txid.GetHex());
    } else {
        PartiallySignedTransaction psbtx(mtx);
        bool complete = false;
        const TransactionError err = pwallet->FillPSBT(psbtx, complete, SIGHASH_ALL, false , true );
        CHECK_NONFATAL(err == TransactionError::OK);
        CHECK_NONFATAL(!complete);
        CDataStream ssTx(SER_NETWORK, PROTOCOL_VERSION);
        ssTx << psbtx;
        result.pushKV("psbt", EncodeBase64(ssTx.str()));
