5e7cc4144b test: add unit test for CConnman::AddedNodesContain() (Jon Atack)
cc62716920 p2p: do not make automatic outbound connections to addnode peers (Jon Atack)
Pull request description:
to allocate our limited outbound slots correctly, and to ensure addnode
connections benefit from their intended protections.
Our addnode logic usually connects the addnode peers before the automatic
outbound logic does, but not always, as a connection race can occur. If an
addnode peer disconnects us and if it was the only one from its network, there
can be a race between reconnecting to it with the addnode thread, and it being
picked as automatic network-specific outbound peer. Or our internet connection
or router or the addnode peer could be temporarily offline, and then return
online during the automatic outbound thread. Or we could add a new manual peer
using the addnode RPC at that time.
The race can be more apparent when our node doesn't know many peers, or with
networks like cjdns that currently have few bitcoin peers.
When an addnode peer is connected as an automatic outbound peer and is the only
connection we have to a network, it can be protected by our new outbound
eviction logic and persist in the "wrong role".
Finally, there does not seem to be a reason to make block-relay or short-lived
feeler connections to addnode peers, as the addnode logic will ensure we connect
to them if they are up, within the addnode connection limit.
Fix these issues by checking if the address is an addnode peer in our automatic
outbound connection logic.

007d6f0e85 test: fix `AddNode` unit test failure on OpenBSD (Sebastian Falbesoner)
Pull request description:
On OpenBSD 7.4, the following check of the unit test `test_addnode_getaddednodeinfo_and_connection_detection` currently fails:
```
BOOST_CHECK(!connman->AddNode({/*m_added_node=*/"127.1", /*m_use_v2transport=*/true}));
```
The reason for that is that this OS seemingly doesn't support the IPv4 shorthand notation with omitted zero-bytes:
```
$ ping 127.1
ping: no address associated with name
```
As a simple fix, this PR skips the check for this with a pre-processor #if. On NetBSD and FreeBSD, `127.1` is resolved correctly to localhost and hence the test passes (thanks to vasild for verifying on the latter!).

d5b4c0b69e pool: change memusage_test to use int64_t, add allocation check (Martin Leitner-Ankerl)
ce881bf9fc pool: make sure PoolAllocator uses the correct alignment (Martin Leitner-Ankerl)
Pull request description:
The class `CTxOut` has a member `CAmount` which is an int64_t, and on ARM 32bit int64_t are 8 byte aligned, which is larger than the pointer alignment of 4 bytes.
So for `CCoinsMap` to be able to use the pool, we need to use the alignment of the member instead of just `alignof(void*)`.

If alignment of the PoolAllocator would be insufficient, then the test would fail. This also catches the issue with ARM 32bit,
where int64_t is aligned to 8 bytes but void* is aligned to 4 bytes. The test adds a check to ensure the pool has allocated
a minimum number of chunks
This changes the PoolAllocator to default the alignment to the given type. This makes the code simpler, and most importantly
fixes a bug on ARM 32bit that caused OOM: The class CTxOut has a member CAmount which is an int64_t and on ARM 32bit int64_t
are 8 byte aligned which is larger than the pointer alignment of 4 bytes. So for CCoinsMap to be able to use the pool, we
need to use the alignment of the member instead of just alignof(void*).

Pull request description:
With Python 3.9 / [PEP 585](https://peps.python.org/pep-0585/), [type hinting has become a little less awkward](https://docs.python.org/3.9/whatsnew/3.9.html#type-hinting-generics-in-standard-collections), as for collection types one doesn't need to import the corresponding capitalized types (`Dict`, `List`, `Set`, `Tuple`, ...) anymore, but can use the built-in types directly (see https://peps.python.org/pep-0585/#implementation for the full list).
This PR applies the replacement for all Python scripts (i.e. in the contrib and test folders) for the basic types, i.e.:
- typing.Dict -> dict
- typing.List -> list
- typing.Set -> set
- typing.Tuple -> tuple
For an additional check, I ran mypy 1.6.1 on both master and the PR branch via
```
$ mypy --ignore-missing-imports --explicit-package-bases $(git ls-files "*.py")
```
and verified that the output is identical -- (from the 22 identified problems, most look like false-positives, it's probably worth it to go deeper here and address them in a follow-up though).
