Pull request description:
This pull request is part of the `libbitcoinkernel` project https://github.com/bitcoin/bitcoin/issues/24303https://github.com/bitcoin/bitcoin/projects/18 and more specifically its "Step 2: Decouple most non-consensus code from libbitcoinkernel". It is also a follow up to #26177.
It replaces pull request https://github.com/bitcoin/bitcoin/pull/27294, which just moved the constants to a new file, but did not re-declare them as enums.
The code move of the chain name constants out of the `chainparamsbase` to their own separate header allows the kernel `chainparams` to no longer include `chainparamsbase`. The `chainparamsbase` contain references to the `ArgsManager` and networking related options that should not belong to the kernel library. Besides this move, the constants are re-declared as enums with helper functions facilitating string conversions.

This commit effectively moves the definition of these constants
out of the chainparamsbase to their own file.
Using the ChainType enums provides better type safety compared to
passing around strings.
The commit is part of an ongoing effort to decouple the libbitcoinkernel
library from the ArgsManager and other functionality that should not be
part of the kernel library.

Pull request description:
Before this PR we had the somewhat confusing combination of methods:
`CNetAddr::ToStringIP()`
`CNetAddr::ToString()` (duplicate of the above)
`CService::ToStringIPPort()`
`CService::ToString()` (duplicate of the above, overrides a non-virtual method from `CNetAddr`)
`CService::ToStringPort()`
Avoid [overriding non-virtual methods](https://github.com/bitcoin/bitcoin/pull/25349/#issuecomment-1185226396).
"IP" stands for "Internet Protocol" and while sometimes "IP addresses" are called just "IPs", it is incorrect to call Tor or I2P addresses "IPs". Thus use "Addr" instead of "IP".
Change the above to:
`CNetAddr::ToStringAddr()`
`CService::ToStringAddrPort()`
The changes touch a lot of files, but are mostly mechanical.

6fefd49527 rpc: Require NodeStateStats object in getpeerinfo (Martin Zumsande)
Pull request description:
The objects `CNode`, `CNodeState` and `Peer` store different info about a peer - `InitializeNode()` and `FinalizeNode()` make sure that for the duration of a connection, we should always have one of each for a peer.
Therefore, there is no situation in which, as part of getpeerinfo RPC, `GetNodeStateStats()` (which requires a `CNodeState` and a `Peer` entry for a `NodeId` to succeed) could fail for a legitimate reason while the peer is connected - this can only happen if there is a race condition between peer disconnection and the `getpeerinfo` processing (see also a more detailed description of this in https://github.com/bitcoin/bitcoin/pull/26457#pullrequestreview-1181641835).
But in this case I think it's better to just not include the newly disconnected peer in the response instead of returning just parts of its data.
An earlier version of this PR also made the affected `CNodeStateStats` fields non-optional (see 5f900e27d0). Since this conflicts with #25923 and should be a separate discussion, I removed that commit from this PR.

Both methods do the same thing, so simplify to having just one.
`ToString()` is too generic in this case and it is unclear what it does,
given that there are similar methods:
`ToStringAddr()` (inherited from `CNetAddr`),
`ToStringPort()` and
`ToStringAddrPort()`.
Both methods do the same thing, so simplify to having just one.
Further, `CService` inherits `CNetAddr` and `CService::ToString()`
overrides `CNetAddr::ToString()` but the latter is not virtual which
may be confusing. Avoid such a confusion by not having non-virtual
methods with the same names in inheritance.
"IP" stands for "Internet Protocol".
"IP address" is sometimes shortened to just "IP" or "address".
However, Tor or I2P addresses are not "IP addresses", nor "IPs".
Thus, use "Addr" instead of "IP" for addresses that could be IP, Tor or
I2P addresses:
`CService::ToStringIPPort()` -> `CService::ToStringAddrPort()`
`CNetAddr::ToStringIP()` -> `CNetAddr::ToStringAddr()`

There is no situation in which CNodeStateStats could be
missing for a legitimate reason - this can only happen if
there is a race condition between peer disconnection and
the getpeerinfo call, in which case the disconnected peer
doesn't need to be included in the response.

1dc03dda05 [doc] remove non-signaling mentions of BIP125 (glozow)
32024d40f0 scripted-diff: remove mention of BIP125 from non-signaling var names (glozow)
Pull request description:
We have pretty thorough documentation of our RBF policy in doc/policy/mempool-replacements.md. It enumerates each rule with several sentences of rationale. Also, each rule pretty much has its own function (3 and 4 share one), with extensive comments. The doc states explicitly that our rules are similar but differ from BIP125, and contains a record of historical changes to RBF policy.
We should not use "BIP125" as synonymous with our RBF policy because:
- Our RBF policy is different from what is specified in BIP125, for example:
- the BIP does not mention our rule about the replacement feerate being higher (our Rule 6)
- the BIP uses minimum relay feerate for Rule 4, while we have used incremental relay feerate since #9380
- the "inherited signaling" question (CVE-2021-31876). Call it discrepancy, ambiguous wording, doc misinterpretation, or implementation details, I would recommend users refer to doc/policy/mempool-replacements.md
- the signaling policy is configurable, see #25353
- Our RBF policy may change further
- We have already marked BIP125 as only "partially implemented" in docs/bips.md since 1fd49eb498
- See comments from people who are not me recently:
- https://github.com/bitcoin/bitcoin/pull/25038#discussion_r909507429
- https://github.com/bitcoin/bitcoin/pull/25575#issuecomment-1179519204
This PR removes all non-signaling mentions of BIP125 (if people feel strongly, we can remove all mentions of BIP125 period). It may be useful to refer to the concept of "tx opts in to RBF if it has at least one nSequence less than (0xffffffff - 1)" as "BIP125 signaling" because:
- It is succint.
- It has already been widely marketed as BIP125 opt-in signaling.
- Our API uses it when referring to signaling (e.g. getmempoolentry["bip125-replaceable"] and wallet error message "not BIP 125 replaceable"). Changing those is more invasive.
- If/when we have other ways to signal in the future, we can disambiguate them this way. See #25038 which proposes another way of signaling, and where I pulled these commits from.
Alternatives:
- Changing our policy to match BIP125. This doesn't make sense as, for example, we would have to remove the requirement that a replacement tx has a higher feerate (Rule 6).
- Changing BIP125 to match what we have. This doesn't make sense as it would be a significant change to a BIP years after it was finalized and already used as a spec to implement RBF in other places.
- Document our policy as a new BIP and give it a number. This might make sense if we don't expect things to change a lot, and can be done as a next step.

fadd8b2676 addrman: Use system time instead of adjusted network time (MarcoFalke)
Pull request description:
This changes addrman to use system time for address relay instead of the network adjusted time.
This is an improvement, because network time has multiple issues:
* It is non-monotonic, even if the system time is monotonic.
* It may be wrong, even if the system time is correct.
* It may be wrong, if the system time is wrong. For example, when the node has limited number of connections (`4`), or the system time is wrong by too much (more than +-70 minutes), or the system time only got wrong after timedata collected more than half of the entries while the time was correct, ...)
This may slightly degrade addr relay for nodes where timedata successfully adjusted the time. Addr relay can already deal with minor offsets of up to 10 minutes. Offsets larger than this should still allow addr relay and not result in a DoS.

Our RBF policy is different from the rules specified in BIP125. For
example, the BIP does not mention Rule 6, and our Rule 4 uses the
(configurable) incremental relay feerate (distinct from the
minimum relay feerate). Those interested in our policy should refer to
doc/policy/mempool-replacements.md instead. These rules may also
continue to diverge with package RBF and other RBF improvements. Keep
references to the BIP125 signaling wrt sequence numbers, since that is
still correct and widely used. It is helpful to refer to this as "BIP125
signaling" since it is unambiguous and succint, especially if we have
multiple ways to signal replaceability in the future.
The rule numbers in doc/policy/mempool-replacements.md correspond
largely to those of BIP 125, so we can still refer to them like "Rule 5."

fa23c19750 univalue: Avoid narrowing and verbose int constructors (MacroFake)
fa3a9a1e8d rpc: Select int-UniValue constructor for enum value in upgradewallet RPC (MacroFake)
Pull request description:
As UniValue provides several constructors for integral types, the
compiler is unable to select one if the passed type does not exactly
match. This is unintuitive for developers and forces them to write
verbose and brittle code. (Refer to `-Wnarrowing` compiler warning)
For example, there are many places where an unsigned int is cast to a
signed int. While the cast is safe in practice, it is still needlessly
verbose and confusing as the value can never be negative. In fact it
might even be unsafe if the unsigned value is large enough to map to a
negative signed one.
Fix this issue and other (minor) type issues.
