Use port=0 for dynamic port allocation in test framework components
to avoid "address already in use" errors from concurrent tests or
ports stuck in TIME_WAIT state from previous test runs.
Changes:
- socks5.py: Update conf.addr after bind() to reflect actual port
- p2p.py: Retrieve actual port after create_server() when port=0
- feature_proxy.py: Use port=0 for all SOCKS5 proxy servers
- feature_anchors.py: Use port=0 for onion proxy server
`TestNode::add_outbound_p2p_connection()` is the only place where
addconnection test-only RPC is used. here, we always pass the
appropriate v2transport option to addconnection RPC.
currently the v2transport option for addconnection RPC is optional.
so simply make the v2transport option mandatory instead.

Pull request description:
This function (`check_node_connections`) exists in `feature_anchors.py` and `p2p_add_connections.py` and does the same thing in both, this PR moves this function to util to avoid repetition and facilitate maintenance.

The previous diff touched most files in ./test/, so bump the headers to
avoid having to touch them again for a bump later.

This prevents the node from trying to connect to random IPs on the internet
while running the functional tests. Exceptions are added when required for
the test to pass.
