97df4e38879d2644aeec34c1eef241fed627333e net: store best block tip time inside PeerManager (furszy)
Pull request description:
Derived from #28120 discussion.
By relocating the peer desirable services flags into the peer manager, we
allow the connections acceptance process to handle post-IBD potential
stalling scenarios.
The peer manager will be able to dynamically adjust the services flags
based on the node's proximity to the tip (back and forth). Allowing the node
to recover from the following post-IBD scenario:
Suppose the node has successfully synced the chain, but later experienced
dropped connections and remained inactive for a duration longer than the limited
peers threshold (the timeframe within which limited peers can provide blocks). In
such cases, upon reconnecting to the network, the node might only establish
connections with limited peers, filling up all available outbound slots. Resulting
in an inability to synchronize the chain (because limited peers will not provide
blocks older than the `NODE_NETWORK_LIMITED_MIN_BLOCKS` threshold).

Small and simple issue reported [here](https://community.umbrel.com/t/bitcoin-docker-container-keeps-restarting/2144).
Improving a confusing situation reported by users who did not understand why a
settings parsing error occurred when the file was empty and did not know how to solve it.
Empty setting file could be due (1) corruption or (2) an user manually cleaning up the file content.
In both scenarios, the 'Unable to parse settings file' error does not help the user move forward.

74ebd4d1359edce82a134dfcd3da9840f8d206e2 doc, test: Test and explain service flag handling (Martin Zumsande)
Pull request description:
Service flags received from the peer-to-peer network are handled differently, depending on how we receive them.
If received directly from an outbound peer the flags belong to, they replace existing flags.
If received via gossip relay (so that anyone could send them), new flags are added, but existing ones but cannot be overwritten.
Document that and add test coverage for it.

No behavior change. Just an intermediate refactoring.
By relocating the peer desirable services flags into the peer
manager, we allow the connections acceptance process to handle
post-IBD potential stalling scenarios.
In the follow-up commit(s), the desirable service flags will be
dynamically adjusted to detect post-IBD stalling scenarios (such
as a +48-hour inactive node that must prefer full node connections
instead of limited peer connections because they cannot provide
historical blocks). Additionally, this encapsulation enable us
to customize the connections decision-making process based on
new user's configurations in the future.

* CentOS-like 8/9 Stream: All Clang versions from 15 to 17
* FreeBSD 12/13: All Clang versions from 15 to 16
* OpenSuse Tumbleweed ships with https://software.opensuse.org/package/clang (`clang17`); No idea about OpenSuse Leap
On operating systems where the clang version is not shipped by default, the user would have to use GCC, or install clang in a different way. For example:
* https://packages.debian.org/bullseye/g++ (g++-10)
* https://packages.ubuntu.com/focal/g++-10

Pull request description:
Replace `LogPrint*` functions with severity based logging functions:
* `LogInfo(...)`, `LogWarning(...)`, `LogError(...)` for unconditional (uncategorised) logging (replaces `LogPrintf`)
* `LogDebug(CATEGORY, ...)` and `LogTrace(CATEGORY, ...)` for conditional logging (replaces `LogPrint`)
* `LogPrintLevel(CATEGORY, LEVEL, ...)` for when the level isn't known in advance, or a category needs to be added for an info/warning/error log message (mostly unchanged, but rarely needed)
Logs look roughly as they do now with `LogInfo` not having an `[info]` prefix, and `LogDebug` having a `[cat]` prefix, rather than a `[cat:debug]` prefix. This removes `BCLog::Level::None` entirely -- for `LogFlags::NONE` just use `Level::Info`, for any actual category, use `Level::Debug`.
Adds docs to developer-notes about when to use which level.
Adds `-loglevelalways=1` option so that you get `[net:debug]`, `[all:info]`, `[all:warning]` etc, which might be helpful for automated parsing, or just if you like everything to be consistent. Defaults to off to reduce noise in the default config, and to avoid unnecessary changes on upgrades.
Changes the behaviour of `LogPrintLevel(CATEGORY, BCLog::Level::Info, ...)` to be logged unconditionally, rather than only being an additional optional logging level in addition to trace and debug. Does not change the behaviour of `LogPrintLevel(NONE, Debug, ...)` and `LogPrintLevel(NONE, Trace, ...)` being no-ops.

`CPubKey::VerifyPubKey` uses rng internally which leads to instability
in the fuzz test.
We fix this by avoiding `VerifyPubKey` in the test and verifying the
decoded public key with a fuzzer chosen message instead.

In reality some mempool transaction might be submitted in a package,
so change m_submitted_in_package to fuzz data provider boolean just like
m_has_no_mempool_parents.
The boolean indicates whether the transaction was added without enforcing mempool
fee limits. m_mempool_limit_bypassed is the correct variable name.
Also changes NewMempoolTransactionInfo booleans descriptions to the format that
is consistent with the codebase.
Making the `GenerateRandomKey` helper available to other modules via
key.{h.cpp} allows us to create random private keys directly at
instantiation of CKey, in contrast to the two-step process of creating
the instance and then having to call `MakeNewKey(...)`.

Pull request description:
This change drops `shutdown.h` and `shutdown.cpp` files, replacing them with a `NodeContext::shutdown` member which is used to trigger shutdowns directly. This gets rid of an unnecessary layer of indirection, and allows getting rid of the `kernel::g_context` global.
Additionally, this PR tries to improve error handling of `SignalInterrupt` code by marking relevant methods `[[nodiscard]]` to avoid the possibility of uncaught exceptions mentioned https://github.com/bitcoin/bitcoin/pull/27861#discussion_r1255496707.
Behavior is changing In a few cases which are noted in individual commit messages. Particularly: GUI code more consistently interrupts RPCs when it is shutting down, shutdown state no longer persists between unit tests, the stop RPC now returns an RPC error if requesting shutdown fails instead of aborting, and other failed shutdown calls now log errors instead of aborting.
This PR is a net reduction in lines of code, but in some cases the explicit error handling and lack of global shutdown functions do make it more verbose. The verbosity can be seen as good thing if it discourages more code from directly triggering shutdowns, and instead encourages code to return errors or send notifications that could be translated into shutdowns. Probably a number of existing shutdown calls could just be replaced by better error handling.
