Pull request description:
(chopped off from #19031 to ease review)
Add an optional support to serialize/unserialize `CNetAddr` in ADDRv2 format (BIP155). The new serialization is engaged by ORing a flag into the stream version.
So far this is only used in tests to ensure the new code works as expected.

ACK 7be6ff6187 I built the PR on macOS Catalina 10.15.6, ran both tests and functional tests. I've reviewed the code and think the changes look good and according to BIP155. I verified that the added Base32 encoding test looks as proposed and working. I've run a node for a week only with Onion addresses `-onlynet=onion` without issues and I can connect to other peer reviewers running TorV3 on their nodes and I can connect both of my test nodes to each other.

re-ACK 7be6ff6187 per `git diff b9c46e0 7be6ff6`, debug build, ran/running bitcoind with this change and observed the log and `-netinfo` peer connections while connected as a tor v2 service to both tor v2 peers and also five tor v3 peers.

ACK 7be6ff6187, tested on Linux Mint 20 (x86_64): on top of this pull and #19031 I'm able to connect to onion v3 addresses, and jonatack is able to connect to my created onion v3 address.

Replace the memset with C++11 value/aggregate initialisation of
the m_data array, which still ensures the unspecified values end
up as zero-initialised.
This then allows changing UINT256_ONE() from dynamically allocating an
object, to a simpler referencing a static allocation.

Pull request description:
After #19316, we can more directly expose information about the connection type on the `getpeerinfo` RPC. Doing so also makes the existing addnode field redundant, so this PR begins the process of deprecating this field.
This PR also includes one commit that improves a log message, as both use a shared function to return the connection type as a string.

Pull request description:
The `TestNode` has a `p2p` property which is an alias for `p2ps[0]`.
I think this should be removed because it can be confusing and misleading (to both the test writer and reviewer), especially if a TestNode has multiple p2ps connected (which is the case for many tests).
Another example is when a test has multiple subtests that connect 1 p2p and use the `p2p` property to reference it. If the subtests don't completely clean up after themselves, the subtests may affect one another.
The best way to refer to a connected p2p is use the object returned by `add_p2p_connection` like this:
```py
p2p_conn = node.add_p2p_connection(P2PInterface())
```
A good example is [p2p_invalid_locator.py](https://github.com/bitcoin/bitcoin/blob/master/test/functional/p2p_invalid_locator.py), which cleans up after itself (waits in both `wait_for_disconnect` and in `disconnect_p2ps`) but wouldn't need so much complexity if it just referenced the connections directly.
If there is only one connected, it's not really that tedious to just use `node.p2ps[0]` instead of `node.p2p` (and it can always be aliased inside the test itself).

fa14f57fbc Assert that RPCArg names are equal to CRPCCommand ones (net, rpcwallet) (MarcoFalke)
Pull request description:
This is the last part split out from #18531 to just touch some RPC methods. Description from the main pr:
### Motivation
RPCArg names in the rpc help are currently only used for documentation. However, in the future they could be used to teach the server the named arguments. Named arguments are currently registered by the `CRPCCommand`s and duplicate the RPCArg names from the documentation. This redundancy is fragile, and has lead to errors in the past (despite having linters to catch those kind of errors). See section "bugs found" for a list of bugs that have been found as a result of the changes here.
### Changes
The changes here add an assert in the `CRPCCommand` constructor that the RPCArg names are identical to the ones in the `CRPCCommand`.
### Future work
> Here or follow up, makes sense to also assert type of returned UniValue?
Sure, but let's not get ahead of ourselves. I am going to submit any further works as follow-ups, including:
* Removing the CRPCCommand arguments, now that they are asserted to be equal and thus redundant
* Removing all python regex linters on the args, now that RPCMan can be used to generate any output, including the cli.cpp table
* Auto-formatting and sanity checking the RPCExamples with RPCMan
* Checking passed-in json in self-check. Removing redundant checks
* Checking returned json against documentation to avoid regressions or false documentation
* Compile the RPC documentation at compile-time to ensure it doesn't change at runtime and is completely static
### Bugs found
* The assert identified issue #18607
* The changes itself fixed bug #19250

Pull request description:
This PR creates a new ZMQ notifier that gives a "total hash history" of block (dis)connection, mempool addition/substraction, all in one pipeline. It also exposes a "mempool sequence number" to both this notifier and `getrawmempool` results, which allows the consumer to use the results together without confusion about ordering of results and without excessive `getrawmempool` polling.
See the functional test `interfaces_zmq.py::test_mempool_sync` which shows the proposed user flow for the client-side tracking of mempool contents and confirmations.
Inspired by https://github.com/bitcoin/bitcoin/pull/19462#issuecomment-656140421
Alternative to https://github.com/bitcoin/bitcoin/pull/19462 due to noted deficiencies in current zmq notification streams.
Also fixes a legacy zmq test that didn't actually trigger a reorg because of identical blocks being generated on each side of the split(oops)

m_valid implies the block solution has been checked, which is not the
case. It only means the txs could be parsed. C++17 comes with
std::optional, so just use that instead.
Using the zmq notifications to avoid excessive mempool polling can be difficult
given the current notifications available. It announces all transactions
being added to mempool or included in blocks, but announces no evictions
and gives no indication if the transaction is in the mempool or a block.
Block notifications for zmq are also substandard, in that it only announces
block tips, while all block transactions are still announced.
This commit adds a unified stream which can be used to closely track mempool:
1) getrawmempool to fill out mempool knowledge
2) if txhash is announced, add or remove from set
based on add/remove flag
3) if blockhash is announced, get block txn list,
remove from those transactions local view of mempool
4) if we drop a sequence number, go to (1)
The mempool sequence number starts at the value 1, and
increments each time a transaction enters the mempool,
or is evicted from the mempool for any reason, including
block inclusion. The mempool sequence number is published
via ZMQ for any transaction-related notification.
These features allow for ZMQ/RPC consumer to track mempool
state in a more exacting way, without unnecesarily polling
getrawmempool. See interface_zmq.py::test_mempool_sync for
example usage.

In addition to adding more specificity to the log statement about the type of
connection, this change also consolidates two statements into one. Previously,
the second one should have never been hit, since block-relay connections would
match the "!IsInboundConn()" condition and return early.

- replaces two `CNode` members, `nRecvVersion` `nSendVersion`, with `m_greatest_common_version`
- removes duplicated getter and setter
There is no change in behavior on the P2P network.
