A target field was added to the getblock and getblockheader RPC calls in bitcoin#31583, but it mistakingly always used the tip value.
Because regtest does not have difficulty adjustment, a test is added for mainnet instead.

The next commit requires an additional mainnet block which changes the difficulty.
Also fix a few minor mistakes in the test (suite):
- rename the create_coinbase retarger_period argument to halving_period. Before bitcoin#31583 this was hardcoded for regtest where these values are the same.
- drop unused fees argument from mine helper
Finally the CPU miner instructions for generating the alternative mainnet chain are expanded.

Let's say an attacker wants to use/exhaust the network's bandwidth, and
has the choice between renting resources from a commercial provider and
getting the network to "spam" itself it by sending unconfirmed
transactions. We'd like the latter to be more expensive than the former.
The bandwidth for relaying a transaction across the network is roughly
its serialized size (plus relay overhead) x number of nodes. A 1000vB
transaction is 1000-4000B serialized. With 100k nodes, that's 0.1-0.4GB
If the going rate for commercial services is 10c/GB, that's like 1-4c per kvB
of transaction data, so a 1000vB transaction should pay at least $0.04.
At a price of 120k USD/BTC, 100sat is about $0.12. This price allows us
to tolerate a large decrease in the conversion rate or increase in the
number of nodes.

Back when we implemented coin age priority as a miner policy, miners
mempools might admit transactions paying very low fees, but then want to
set a higher fee for block inclusion. However, since coin age priority
was removed in v0.15, the block assembly policy is solely based on fees,
so we do not need to apply minimum feerate rules in multiple places. In
fact, the block assembly policy ignoring transactions that are added to
the mempool is likely undesirable as we waste resources accepting and
storing this transaction.
Instead, rely on mempool policy to enforce a minimum entry feerate to
the mempool (minrelaytxfee). Set the minimum block feerate to the
minimum non-zero amount (1sat/kvB) so it collects everything it finds in
mempool into the block.

The std::source_location conveniently stores the file name, line number,
and function name of a source code location. We switch to using it instead
of the __func__ identifier and the __FILE__ and __LINE__ macros.
BufferedLog is changed to have a std::source_location member, replacing the
source_file, source_line, and logging_function members. As a result,
MemUsage no longer explicitly counts source_file or logging_function as the
std::source_location memory usage is included in the MallocUsage call.
This also changes the behavior of -logsourcelocations as std::source_location
includes the entire function signature. Because of this, the functional test
feature_config_args.py must be changed to no longer include the function
signature as the function signature can differ across platforms.

- Increase block weight by 4000 for all nodes with custom -blockmaxweight.
Prior to this commit, we generated blocks with 4000 weight units less worth of transactions.
See https://github.com/bitcoin/bitcoin/issues/32461#issuecomment-2925282272 for details.

Currently if the version 3 is selected for an otherwise
standard spender, the test will fail. It's unlikely but
possible, so change the test to update expectations and
sample more aggressively on border values to instigate
failures much quicker in the future if another version is

Ensure that tip_header.rehash() is used instead of tip_header.hash, which is None when the header is deserialized from hex.

Rebased-From: 26598ed21ea7228c4ecf85da24527c88f9c1f1c1
The catchup loop in the outbound eviction functional test currently has
a small flaw, as the contained waiting for a `getheaders` message just
waits for any such message instead of one with the intended block hash.
The reason is that the `prev_prev_hash` variable is set incorrectly,
since the `tip_header` instance is not updated and its field `.hash` is
None. Fix that by updating `tip_header` and use the correct field -- we
want the tip header's previous hash (`.hashPrevBlock`).

During init, the test framework will start using rpc after the
mempool was loaded. It will not wait for postInitProcess or
outstanding transactionAddedToMempool notifications, leading to

outstanding notifications.

After fixing the nTime variable name, the test_pruneheight_undo_presence
test began failing because node 2, which is involved in reorg testing,
could be on a different chain than other nodes. This caused failures
when trying to fetch blocks from other nodes that didn't recognize
node 2's chain.
Switch to using node 5 instead, which is also a pruned node but isn't
involved in reorg testing, ensuring it stays on the same chain as the
other nodes. This allows the block fetching to work as intended in the
test.

a3baead7cb8376e3b09f1726b8c466648d187524 validation: use wtxid instead of txid in CheckEphemeralSpends (marcofleon)
Pull request description:
This PR addresses a small bug in [`AcceptMultipleTransactions`](45719390a1/src/validation.cpp (L1598)) where a txid was being inserted into a map that should only hold wtxids. `CheckEphemeralSpends` has an out parameter on failure that records that the child transaction did not spend the parent's dust. Instead of using the txid of this child, use its wtxid.
The second commit in this PR is a refactor of the `PackageMempoolAcceptResult` struct to use the `Wtxid` type instead of `uint256`. This helps to prevent errors like this in the future.

026bb226e96919603af829d0b677779a234a0f6e cmake: Set top-level target output locations (Hennadii Stepanov)
Pull request description:
This PR sets the target output locations to the `bin` and `lib` subdirectories within the build tree, creating a directory structure that mirrors that of the installed targets.
This approach is widely adopted by the large projects, such as [LLVM](e146c1867e/lldb/cmake/modules/LLDBStandalone.cmake (L128-L130)):
```cmake
set(CMAKE_RUNTIME_OUTPUT_DIRECTORY ${CMAKE_BINARY_DIR}/bin)
set(CMAKE_LIBRARY_OUTPUT_DIRECTORY ${CMAKE_BINARY_DIR}/lib${LLVM_LIBDIR_SUFFIX})
set(CMAKE_ARCHIVE_OUTPUT_DIRECTORY ${CMAKE_BINARY_DIR}/lib${LLVM_LIBDIR_SUFFIX})
```
The `libsecp256k1` project has also recently [adopted](https://github.com/bitcoin-core/secp256k1/pull/1553) this approach.
With this PR, all binaries are conveniently located. For example, run:
```
$ ./build/bin/fuzz
```
instead of:
```
$ ./build/src/test/fuzz/fuzz
```
On Windows, all required DLLs are now located in the same directory as the executables, allowing to run `bitcoin-chainstate.exe` (which loads `bitcoinkernel.dll`) without the need to copy DLLs or modify the `PATH` variable.
The idea was briefly discussed among the build team during the recent CoreDev meeting.
---
**Warning**: This PR changes build locations of newly built executables like `bitcoind` and `test_bitcoin` from `src/` to `bin/` without deleting previously built executables. A clean build is recommended to avoid accidentally running old binaries.

Pull request description:
In Python the meaning of `args or argsn` is that `argsn` is fully ignored when `args` is a list with at least one element. However, the RPC server accepts mixed positional and named args in the same RPC.
Fix the debug log by always printing both. Also, add a new `_json_dumps` helper to avoid bloated code.
Can be tested via `--tracerpc` on a call that uses named args mixed with positional args.
