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

Now that we require Python 3.6+, we should be using variable type
annotations directly rather than # type: comments.
Also takes care of the discarded value issue in p2p_message_capture.py.
See: https://github.com/bitcoin/bitcoin/pull/19509/files#r571674446.
Add a functional test for CaptureMessage. This connects and then
disconnects a peer so that the handshake can be used to check if capture
is being done correctly.
Included in a docstring in the test is the following:
From the data file we'll only check the structure.
We won't care about things like:
- Deserializing the payload of the message
- This is managed by the deserialize methods in
test_framework.messages
- The order of the messages
- There's no reason why we can't, say, change the order of the
messages in the handshake
- Message Type
- We can add new message types
We're ignoring these because they're simply too brittle to test here.
