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.

Wait until the node's process has fully stopped before starting a new instance.
Since the same code is used in tool_wallet.py, this consolidates the behavior
into a 'kill_process()' function.

026bb226e9 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.

fac1dd9dff test: Fix authproxy named args debug logging (MarcoFalke)
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.

Pull request description:
* This PR attempts to fix the duplicate coinbase weight reservation issue we currently have.
* Fixes#21950
We reserve 4000 weight units for coinbase transaction in `DEFAULT_BLOCK_MAX_WEIGHT`
7590e93bc7/src/policy/policy.h (L23)
And also reserve additional `4000` weight units in the default `BlockCreationOptions` struct.
7590e93bc7/src/node/types.h (L36-L40)
**Motivation**
- This issue was first noticed during a review here https://github.com/bitcoin/bitcoin/pull/11100#discussion_r136157411)
- It was later reported in issue #21950.
- I also came across the bug while writing a test for building the block template. I could not create a block template above `3,992,000` in the block assembler, and this was not documented anywhere. It took me a while to realize that we were reserving space for the coinbase transaction weight twice.
---
This PR fixes this by consolidating the reservation to be in a single location in the codebase.
This PR then adds a new startup option `-blockreservedweight` whose default is `8000` that can be used to lower or increase the block reserved weight for block header, txs count, coinbase tx.

d45eb3964f test: compare BDB dumps of test framework parser and wallet tool (Sebastian Falbesoner)
01ddd9f646 test: complete BDB parser (handle internal/overflow pages, support all page sizes) (Sebastian Falbesoner)
Pull request description:
This PR adds missing features to our test framework's BDB parser with the goal of hopefully being able to read all legacy wallets that are created with current and past versions of Bitcoin Core. This could be useful both for making review of https://github.com/bitcoin/bitcoin/pull/26606 easier and to also possibly improve our functional tests for the wallet BDB-ro parser by additionally validating it with an alternative implementation. The second commits introduces a test that create a legacy wallet with huge label strings (in order to create overflow pages, i.e. pages needed for key/value data than is larger than the page size) and compares the dump outputs of wallet tool and the extended test framework BDB parser.
It can be exercised via `$ ./test/functional/tool_wallet.py --legacy`. BDB support has to be compiled in (obviously).
For some manual tests regarding different page sizes, the following patch can be used:
```diff
diff --git a/src/wallet/bdb.cpp b/src/wallet/bdb.cpp
index 38cca32f80..1bf39323d3 100644

fad441fba0 test: Treat leftover process as error (MarcoFalke)
Pull request description:
The `--noshutdown` flag is brittle, confusing, and redundant:
* Someone wanting to inspect the state after a test failure will likely also want to debug the state on the python side, so the option is redundant with `--pdbonfailure`. If there was a use case to replicate `--pdbonfailure` without starting pdb, a dedicated flag could be added for that use case.
* It is brittle to use the flag for a passing test, because it will disable checks in the test. For example, on shutdown LSan will perform a leak check, and the test framework will check that the node did not crash, and it will check that the node did not print errors to stderr.
Fix all issues by removing it.
Also, tidy up startup error messages to be less confusing as a result.

- Raise an error if the output value is less than or equal to zero in `create_self_transfer`.
This prevents creating transactions with a value of 0 or less.
- Add a test to verify that `create_self_transfer_multi` also respects the passed `target_vsize`.

Trying to shut down a node after a test failure may fail and lead to an
RPC error.
Also, it is confusing to sidestep the existing fallback to kill any
leftover nodes on a test failure.
So just rely on the fallback.
Idea by Hodlinator.
Co-Authored-By: Hodlinator <172445034+hodlinator@users.noreply.github.com>
For blocks 1 through 15 the script_BIP34_coinbase_height appends OP_1
to comply with BIP34 and avoid bad-cb-length.
This is inconsistent with BlockAssembler::CreateNewBlock() which adds
OP_0 instead.
The utxo_total_supply fuzzer and MinerTestingSetup::Block also use OP_0.
Changing it is required to import the test vectors in the next commit.
It also ensures the test vectors can be regenerated using the CPU miner
at https://github.com/pooler/cpuminer without patches (it uses OP_0).
The same helper is used by the signet miner, so this will impact newly
bootstrapped signets.
`p2p_seednode.py` would try to connect to `0.0.0.1` and `0.0.0.2` as
seed nodes. This sends outbound TCP packets on a non-loopback interface
to the default router.
Configure an unavailable proxy for all executions of `bitcoind` during
this test. Also change `0.0.0.1` and `0.0.0.2` because connecting to
them would skip the `-proxy=` setting because for such an address:
* `CNetAddr::IsLocal()` is true, thus
* `CNetAddr::IsRoutable()` is false, thus
* `CNetAddr::GetNetwork()` is `NET_UNROUTABLE`, even though
`CNetAddr::m_net` is `NET_IPV4`.
This speeds up the execution time of `p2p_seednode.py`
from 12.5s to 2.5s.
Trying to immediately shut down a node after a startup failure without
waiting for the RPC to be fully up will in most cases just fail and lead
to an RPC error.
Also, it is confusing to sidestep the existing fallback to kill any
leftover nodes on a test failure.
So just rely on the fallback.
Printing to stderr instead of stdout makes the test_runner.py fail on
leftover processes. This is desired and fine, because a leftover process
should only happen on a test failure anyway.
`get_socket_inodes()` calls `os.listdir()` and then iterates on the
results using `os.readlink()`. However a file may disappear from the
directory after `os.listdir()` and before `os.readlink()` resulting in a
`FileNotFoundError` exception.
It is expected that this may happen for `bitcoind` which is running and
could open or close files or sockets at any time. Thus ignore the
`FileNotFoundError` exception.
If the `releases` directory exists, but still only a subset of the
necessary previous release binaries are available, the test fails by
throwing an exception (sometimes leading to follow-up exceptions like
"AssertionError: [node 0] Error: no RPC connection") and printing out
a stack trace, which can be confusing and at a first glance suggests
that the node crashed or some alike.
Improve this by checking and printing out *all* of the missing release
binaries and failing with an explicit error in this case. Also add an
info on how to download previous releases binaries.
Noticed while testing #30328.
Can be tested by e.g.
$ ./test/get_previous_releases.py -b
$ rm -rf ./releases/v28.0/
$ ./build/test/functional/wallet_migration.py
