Move `SignSchnorr` to `KeyPair`. This makes `CKey::SignSchnorr` now
compute a `KeyPair` object and then call `KeyPair::SignSchorr`. The
notable changes are:
* Move the merkle_root tweaking out of the sign function and into
the KeyPair constructor
* Remove the temporary secp256k1_keypair object and have the
functions access m_keypair->data() directly
Current logging RPC method documentation claims to accept "0" and "none"
categories, but the "none" argument is actually rejected and the "0"
argument is ignored. Update the implementation to refuse both
categories, and remove the help text claiming to support them.
* Make the standalone function `LogCategoryToStr()` private inside
`logging.cpp` (aka `static`) - it is only used in that file.
* Make the method `Logger::GetLogPrefix()` `private` - it is only
used within the class.
* Use `BCLog::NONE` to initialize `m_categories` instead of `0`.
We later check whether it is `BCLog::NONE` (in
`Logger::DefaultShrinkDebugFile()`).
Make special cases explicit in GetLogCategory() and LogCategoryToStr()
functions. Simplify the LOG_CATEGORIES_BY_STR and LOG_CATEGORIES_BY_FLAG
mappings and LogCategoriesList() function.
This makes the maps `LOG_CATEGORIES_BY_STR` and `LOG_CATEGORIES_BY_FLAG`
consistent (one is exactly the opposite of the other).
Follow-up to #30436.
uint256 string representation was wrongfully documented as little-endian due to them being reversed by GetHex() etc, and base_blob::Compare() giving most significance to the beginning of the internal array. They are closer to "big-endian", but this commit tries to be even more precise than that.
uint256_tests.cpp - Avoid using variable from the left side of the condition in the right side.
setup_common.cpp - Skip needless ArithToUint256-conversion.
Add a `KeyPair` class which wraps the `secp256k1_keypair`. This keeps
the secret data in secure memory and enables passing the
`KeyPair` object directly to libsecp256k1 functions expecting a
`secp256k1_keypair`.
Motivation: when passing `CKeys` for taproot outputs to libsecp256k1 functions,
the first step is to create a `secp256k1_keypair` data type and use that
instead. This is so the libsecp256k1 function can determine if the key
needs to be negated, e.g., when signing.
This is a bit clunky in that it creates an extra step when using a `CKey`
for a taproot output and also involves copying the secret data into a
temporary object, which the caller must then take care to cleanse. In
addition, the logic for applying the merkle_root tweak currently
only exists in the `SignSchnorr` function.
In a later commit, we will add the merkle_root tweaking logic to this
function, which will make the merkle_root logic reusable outside of
signing by using the `KeyPair` class directly.

Sanity check that using CKey/CPubKey directly vs using secp256k1_keypair objects
returns the same results for BIP341 key tweaking.

Add benchmarks for signing with null and non-null merkle_root arguments.
Null and non-null merkle_root arguments will apply the taptweaks
H_TapTweak(P) and H_TapTweak(P | merkle_root), respectively, to the
private key during signing.
This benchmark is added to verify there are no significant performance
changes after moving the taptweak signing logic in a later commit.

455fca86cfada1823aa28615b5683f9dc73dbb9a policy: Add OP_1 <0x4e73> as a standard output type (Greg Sanders)
Pull request description:
This is a sub-feature taken out of the original proposal for ephemeral anchors #30239
This PR makes *spending* of `OP_1 <0x4e73>` (i.e. `bc1pfeessrawgf`) standard. Creation of this output type is already standard.
Any future witness output types are considered relay-standard to create, but not to spend. This preserves upgrade hooks, such as a completely new output type for a softfork such as BIP341. It also gives us a bit of room to use a new output type for policy uses.
This particular sized witness program has no other known use-cases (https://bitcoin.stackexchange.com/a/110664/17078), s it affords insufficient cryptographic security for a secure commitment to data, such as a script or a public key. This makes this type of output "keyless", or unauthenticated.
As a witness program, the `scriptSig` of the input MUST be blank, by BIP141. This helps ensure txid-stability of the spending transaction, which may be required for smart contracting wallets. If we do not use segwit, a miner can simply insert an `OP_NOP` in the `scriptSig` without effecting the result of program execution.
An additional relay restriction is to disallow non-empty witness data, which an adversary may use to penalize the "honest" transactor when RBF'ing the transaction due to the incremental fee requirement of RBF rules.
The intended use-case for this output type is to "anchor" the transaction with a spending child to bring exogenous CPFP fees into the transaction package, encouraging the inclusion of the package in a block. The minimal size of creation and spending of this output makes it an attractive contrast to outputs like `p2sh(OP_TRUE)` and `p2wsh(OP_TRUE)` which
are significantly larger in vbyte terms.
Combined with TRUC transactions which limits the size of child transactions significantly, this is an attractive option for presigned transactions that need to be fee-bumped after the fact.

Contributes to #564 by providing an interface for mapLocalHost
through net -> node interface -> clientModel. Later this value can be
read by GUI to show the local addresses.
When the transactions being marked done exactly match the first chunk of
what remains of the linearization, we can just remember to skip that
chunk instead of computing a full rechunking.
Further, chop off prefixes of the input linearization that are already done,
so they don't need to be reconsidered for further rechunkings.

526a87ba6b4f20592ad3c090b82e83ecff2107fc test: add uint256::FromHex unittest coverage (stickies-v)
Pull request description:
Since fab6ddbee6, `TxidFromString()` has been deprecated because it is less robust than the `transaction_identifier::FromHex()` introduced in [the same PR](https://github.com/bitcoin/bitcoin/pull/30482). Specifically, it tries to recover from length-mismatches, recover from untrimmed whitespace, 0x-prefix and garbage at the end, instead of simply requiring exactly 64 hex-only characters.
In this PR, `TxidFromString` is removed completely to clean up the code and prevent further unsafe usage. Unit and fuzz test coverage on `uint256::FromHex()` and functions that wrap it is increased.
Note: `TxidFromSring` allowed users to prefix strings with "0x", this is no longer allowed for `transaction_identifier::FromHex()`, so a helper function for input validation may prove helpful in the future _(this overlaps with the `uint256::uint256S()` vs `uint256::FromHex()` future cleanup)_. It is not relevant to this PR, though, besides the fact that this unused (except for in tests) functionality is removed.
The only users of `TxidFromString` are:
- `test`, where it is straightforward to drop in the new `FromHex()` methods without much further concern
- `qt` coincontrol. There is no need for input validation here, but txids are not guaranteed to be 64 characters. This is already handled by the existing code, so again, using `FromHex()` here seems quite straightforward.
Addresses @maflcko's suggestion: https://github.com/bitcoin/bitcoin/pull/30482#discussion_r1691826934
Also removes `WtxidFromString()`, which is a test-only helper function.
### Testing GUI changes
To test the GUI coincontrol affected lines, `regtest` is probably the easiest way to quickly get some test coins, you can use e.g.
```
alias cli="./src/bitcoin-cli -regtest"
cli createwallet "coincontrol"
# generate 10 spendable outputs on 1 address
cli generatetoaddress 10 $(cli -rpcwallet=coincontrol getnewaddress)
# generate 10 spendable outputs on another address
cli generatetoaddress 10 $(cli -rpcwallet=coincontrol getnewaddress)
# make previous outputs spendable
cli generatetoaddress 100 $(cli -rpcwallet=coincontrol getnewaddress)
```

This adds a fuzzing harness dedicated to the version handshake. To avoid determinism issues, the harness creates necessary components each iteration (addrman, peerman, etc). A harness like this would have easily caught https://bitcoincore.org/en/2024/07/03/disclose-timestamp-overflow/.
As a performance optimization, this PR includes a change to `PeerManager` to lazily initialize various filters (to avoid large unnecessary memory allocations each iteration).

Tested ACK afd237bb5d85923273a69f7b45dc6aae6aa1680e. I compared the coverage of `net_processing` from this harness to the `process_message` and `process_messages` harnesses to see the differences. This target hits more specific parts of the version handshake. The stability looks good as well, at about 94%.

Pull request description:

Should be trivial to disable again, on the first failure.
