Pull request description:
This picks up one of the changes from https://github.com/bitcoin/bitcoin/pull/29232, which is a switch to building libnatpmp with CMake. It includes an update to the most recent version of libnatpmp (f2433bec24), which includes (https://github.com/miniupnp/libnatpmp/pull/43).
From an initial look I couldn't find any significant difference between the Autotools and CMake produced libs.

c87b0a0ff4 zmq: accept unix domain socket address for notifier (Matthew Zipkin)
Pull request description:
This is a follow-up to https://github.com/bitcoin/bitcoin/pull/27375, allowing ZMQ notifications to be published to a UNIX domain socket.
Fortunately, libzmq handles unix sockets already, all we really have to do to support it is allow the format in the actual option.
[libzmq](https://libzmq.readthedocs.io/en/latest/zmq_ipc.html) uses the prefix `ipc://` as opposed to `unix:` which is [used by Tor](https://gitlab.torproject.org/tpo/core/tor/-/blob/main/doc/man/tor.1.txt?ref_type=heads#L1475) and now also by [bitcoind](a85e5a7c9a/doc/release-notes-27375.md?plain=1#L5) so we need to switch that internally.
As far as I can tell, [LND](d20a764486/zmq.go (L38)) supports `ipc://` and `unix://` (notice the double slashes).
With this patch, LND can connect to bitcoind using unix sockets:
Example:
*bitcoin.conf*:
```
zmqpubrawblock=unix:/tmp/zmqsb
zmqpubrawtx=unix:/tmp/zmqst
```
*lnd.conf*:
```
bitcoind.zmqpubrawblock=ipc:///tmp/zmqsb
bitcoind.zmqpubrawtx=ipc:///tmp/zmqst
```

Pull request description:
Recursion is a frequent source of stack overflow bugs. Secondly, introduction of recursion can be non-obvious.
This PR proposes to use the clang-tidy `misc-no-recursion` check to make introduction of new recursion obvious. We don't make use of recursion a lot in our code base but there are a few places that need suppressions anyway (mostly the descriptor and univalue/rpc code).

Pretty much all library packages were renamed in the 64-bit time_t
migration to add `t64` (even on 64-bit platforms).
Instead of complicating the doc with conditional package names, suggest
installing the `-dev` packages which still have the same name, and
besides that, are the right way to go about it as they contain the
"user facing" C++ headers needed to build against Qt5.
For Fedora, devel packages are already suggested.
This affects Ubuntu 24.04 and Debian Testing.

Pull request description:
Closes https://github.com/bitcoin/bitcoin/issues/27252
UNIX domain sockets are a mechanism for inter-process communication that are faster than local TCP ports (because there is no need for TCP overhead) and potentially more secure because access is managed by the filesystem instead of serving an open port on the system.
There has been work on [unix domain sockets before](https://github.com/bitcoin/bitcoin/pull/9979) but for now I just wanted to start on this single use-case which is enabling unix sockets from the client side, specifically connecting to a local Tor proxy (Tor can listen on unix sockets and even enforces strict curent-user-only access permission before binding) configured by `-onion=` or `-proxy=`
I copied the prefix `unix:` usage from Tor. With this patch built locally you can test with your own filesystem path (example):
`tor --SocksPort unix:/Users/matthewzipkin/torsocket/x`
`bitcoind -proxy=unix:/Users/matthewzipkin/torsocket/x`
Prep work for this feature includes:
- Moving where and how we create `sockaddr` and `Sock` to accommodate `AF_UNIX` without disturbing `CService`
- Expanding `Proxy` class to represent either a `CService` or a UNIX socket (by its file path)
Future work:
- Enable UNIX sockets for ZMQ (https://github.com/bitcoin/bitcoin/pull/27679)
- Enable UNIX sockets for I2P SAM proxy (some code is included in this PR but not tested or exposed to user options yet)
- Enable UNIX sockets on windows where supported
- Update Network Proxies dialog in GUI to support UNIX sockets

Pull request description:
Revives #17167. It allows whitelisting manual connections. Fixes#9923
Since there are some PRs/issues around this topic, I'll list some motivations/comments for whitelisting outbound connections from them:
- Speed-up tx relay/mempool sync for testing purposes (my personal motivation for this) - In #26970, theStack pointed out that we whitelist peers to speed up tx relay for fast mempool synchronization, however, since it applies only for inbound connections and considering the topology `node0 <--- node1 <---- node2 <--- ... <-- nodeN`, if a tx is submitted from any node other than node0, the mempool synchronization can take quite long.
- https://github.com/bitcoin/bitcoin/pull/29058#issuecomment-1865155764 - "Before enabling -v2transport by default (which I'd image may happen after https://github.com/bitcoin/bitcoin/pull/24748) we could consider a way to force manual connections to be only-v1 or even only-v2 (disabling reconnect-with-v1). A possibility could be through a net permission flag, if https://github.com/bitcoin/bitcoin/pull/27114 makes it in."
- https://github.com/bitcoin/bitcoin/pull/17167#issuecomment-1168606032 - "This would allow us to use https://github.com/bitcoin/bitcoin/pull/25355 when making outgoing connections to all nodes, except to whitelisted ones for which we would use our persistent I2P address."
- Force-relay/mempool permissions for a node you intentionally connected to.

Delving Bitcoin discussion thread: https://delvingbitcoin.org/t/v3-transaction-policy-for-anti-pinning/340
Delving Bitcoin discussion for LN usage: https://delvingbitcoin.org/t/lightning-transactions-with-v3-and-ephemeral-anchors/418
Rationale:
- There are various pinning problems with RBF and our general ancestor/descendant limits. These policies help mitigate many pinning attacks and make package RBF feasible (see #28984 which implements package RBF on top of this). I would focus the most here on Rule 3 pinning. [1][2]
- Switching to a cluster-based mempool (see #27677 and #28676) requires the removal of CPFP carve out, which applications depend on. V3 + package RBF + ephemeral anchors + 1-parent-1-child package relay provides an intermediate solution.
V3 policy is for "Priority Transactions." [3][4] It allows users to opt in to more restrictive topological limits for shared transactions, in exchange for the more robust fee-bumping abilities that offers. Even though we don't have cluster limits, we are able to treat these transactions as having as having a maximum cluster size of 2.
Immediate benefits:
- You can presign a transaction with 0 fees (not just 1sat/vB!) and add a fee-bump later.
- Rule 3 pinning is reduced by a significant amount, since the attacker can only attach a maximum of 1000vB to your shared transaction.
This also enables some other cool things (again see #27463 for overall roadmap):
- Ephemeral Anchors
- Package RBF for these 1-parent-1-child packages. That means e.g. a commitment tx + child can replace another commitment tx using the child's fees.
- We can transition to a "single anchor" universe without worrying about package limit pinning. So current users of CPFP carve out would have something else to use.
- We can switch to a cluster-based mempool [5] (#27677#28676), which removes CPFP carve out [6].

[2]: A FAQ is "we need this for cluster mempool, but is this still necessary afterwards?" There are some pinning issues that are fixed here and not fully fixed in cluster mempool, so we will still want this or something similar afterward.
