873beca6d [tests] Rename NodeConn and NodeConnCB (John Newbery)
Pull request description:
Final step in #11518
NodeConn -> P2PConnection
NodeConnCB -> P2PInterface
This is basically just a rename. Should be an easy review.

* [tests] Remove mininode periodic (half-hour) ping messages
* [tests] Tidy up mininode
Add docstrings and renames some methods.
Also removes the redundant NodeConn.readable() method override.
* [tests] Move only: move NodeConnCB below NodeConn
This is required since NodeConnCB will inherit from NodeConn
after the next commit.
* [tests] Make NodeConnCB a subclass of NodeConn
This makes NodeConnCB a subclass of NodeConn, and
removes the need for the client code to know
anything about the implementation details of NodeConnCB.
NodeConn can now be swapped out for any other implementation
of a low-level connection without changing client code.
* [tests] Move version message sending from NodeConn to NodeConnCB
This commit moves the logic that sends a version message
on connection from NodeConn to NodeConnCB. NodeConn should
not be aware of the semantics or meaning of the P2P payloads.
* remove witness

Pull request description:
Final two steps of #10082 : Adding the "mininode" P2P interface to `TestNode`
This PR adds the mininode P2P interface to `TestNode`. It simplifies the process for opening a P2P connection to the node-under-test from this:
```python
node0 = NodeConnCB()
connections = []
connections.append(NodeConn('127.0.0.1', p2p_port(0), self.nodes[0], node0))
node0.add_connection(connections[0])
```
to this:
```python
self.nodes[0].add_p2p_connection(p2p_conn_type=NodeConnCB)
```
The first commit adds the infrastructure to `test_node.py`. The second updates the individual test cases to use it. Can be separated if this is too much review for one PR.

This speeds up assumevalid.py from 22s to 7s on my machine. On travis, this
should be an improvement of a few minutes. Without this, Travis actually
fails due to block download timeouts.

Pull request description:
Some additional tidyups after the introduction of TestNode:
- commit 1 makes TestNode use the correct rpc timeout. This should have been included in #11077
- commit 2 separates `add_node()` from `start_node()` as originally discussed here: https://github.com/bitcoin/bitcoin/pull/10556#discussion_r121161453 with @kallewoof . The test writer no longer needs to assign to `self.nodes` when starting/stopping nodes.
- commit 3 adds a `set_test_params()` method, so individual tests don't need to override `__init__()` and call `super().__init__()`

e9e939108 [tests] Check connectivity before sending in assumevalid.py (John Newbery)
Pull request description:
assumevalid.py would try to send over a closed P2P connection in a loop,
hitting the following failure many times:
`TestFramework.mininode (ERROR): Cannot send message. No connection to node!`
The test still passed, but this is a lot of noise in the test log.
Just check that the connection is open before trying to send.

We only want to verify that assumevalid causes block 102 to be accepted
even though it contains an invalid script, so there is no need to send
more blocks.
Dash has only 1/4 of block time compared to Bitcoin, which requires 4 times
the amount of headers so that the assumevalid check in ConnectBlock results
in skipping of script checks.
Using so many headers now causes block time validation to fail (too far in
the future), so we need to adjust mock time as well.
