Pull request description:
This PR adds a few tests that are bloomfilter-related, including behavior for when bloomfilters are turned _off_:
1. Tests p2p message `msg_mempool`: a node that has `peerbloomfilters` enabled should send its mempool (disabled behavior already tested [here](https://github.com/bitcoin/bitcoin/blob/master/test/functional/p2p_mempool.py)).
2. Tests that bloomfilter peers with [`fRelay=False`](https://github.com/bitcoin/bips/blob/master/bip-0037.mediawiki#extensions-to-existing-messages) in the `version` message should not receive any invs until they set the filter. The rest is the same as what’s already tested in `p2p_filter.py`.
3. Tests that peers get disconnected if they send `filterload` or `filteradd` p2p messages to a node with bloom filters disabled.
4. Refactor: renames p2p_mempool.py to p2p_nobloomfilter_messages.py.
5. Fixes race conditions in p2p_filter.py

-A node with bloomfilters disabled should disconnect peers that send
msg_mempool, msg_filterload, or msg_filteradd.
-Renamed the test because it now has a wider scope and msg_mempool's
actual functionality makes more sense for p2p_filter.py.
-msg_mempool is currently only tested with bloomfilter disabled
(node is disconnected) in p2p_mempool.py
-msg_mempool should get mempool txns in response when bloomfilter
is enabled
-edit test that doesn't test msg_mempool as intended

Pull request description:
This PR gets rid of another unnecessary use of raw pointers, similar to PR #19053 (see also issue #19062 where useful commands for finding potential candidates are listed) but in the tx verification module.
For the functions `CalculateSequenceLocks()` and `SequenceLocks()`, the `prevHeights` vector parameter type is changed to be passed as a reference. Note that there were no checks for null pointers -- if one would pass `nullptr` to one of the functions, the following line would immediately lead to a crash:

34645c4dd0 Test txinwitness is accessible on coinbase vin (Rod Vagg)
3e4421070a Expose txinwitness for coinbase in JSON form (Rod Vagg)
Pull request description:
## Rationale
The CLI can provide you with everything about transactions and blocks that you need to reconstruct the block structure and raw block itself **except** for the witness commitment nonce which is stored in the `scriptWitness` of the coinbase and is not printed. You could manually parse the raw `"hex"` fields for transactions if you really wanted to, but this seems to defeat the point of having a JSONification of the raw block/transaction data.
Without the nonce you can't:
1. calculate and validate the witness commitment yourself, you can generate the witness tx merkle root but you don't have the nonce to combine it with
2. reconstruct the raw block form because you don't have `scriptWitness` stack associated with the coinbase (although you know how big it will be and can guess the common case of `[0x000...000]`)
I'm building some archiving tooling for block data and being able to do a validated two-way conversion is very helpful.
## What
This PR simply makes the `txinwitness` field not dependent on whether we are working with the coinbase or not. So you get it for the coinbase as well as the rest.
## Examples
Common case of a `[0x000...000]` nonce: 00000000000000000000140a7289f3aada855dfd23b0bb13bb5502b0ca60cdd7

"vin": [

],
"sequence": 4294967295
}

Novel nonce value: 000000000000000000008c31945b2012258366cc600a3e9a3ee0598e8f797731

],
"sequence": 4294967295
}
],
...
```
## Alternatives
This field could be renamed for the coinbase, `"witnessnonce"` perhaps. It could also be omitted when null/zero (`0x000...000`).
## Tests
This didn't break any tests and I couldn't find an obvious way to include a test for this. If this is desired I'd apreicate some pointers.

There's no harm in calling `disconnect_nodes` for nodes that weren't connected (in this case it's a no-op). However, detecting this case and logging a warning can help ensure that tests are behaving as expected.
In addition, since `disconnect_nodes` works bidirectionally, I removed all instances of this pattern:

disconnect_nodes(self.nodes[0], 1)
