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.

- 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.
This commit fixes it by increasing the block weight by 4000.

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
made standard.

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

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
a possible race, in which listunspent is being called while the
tx is still in Inactive status. Prevent this by processing
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.

474139aa9bf7109df78e46936e5a649c70703386 wallet: abandon inactive coinbase tx and their descendants during startup (furszy)
Pull request description:
Since #26499, we mark coinbase transactions and their descendants as abandoned when a reorg arises through the "block disconnection" signal handler. However, this does not cover all scenarios; external wallets could contain coinbase transactions from blocks the node has not seen yet, or the user could have replaced the chain with an earlier or different version (one without the coinbase chain).
This affects balance calculation as well as mempool rebroadcast (descendants shouldn't be relayed).
Fix this by marking orphaned coinbase transactions and their descendants as abandoned during wallet startup.

This is very closely based on [test/functional/wallet_multisig_descriptor_psbt.py](https://github.com/bitcoin/bitcoin/blob/master/test/functional/wallet_multisig_descriptor_psbt.py) both in code and concept. It should serve as some integration testing for Miniscript descriptors, and also documents a simple multisig that starts as 4-of-4 and decays to 3-of-4, 2-of-4, and finally 1-of-4 at block heights (I think in the real world aligning this to halvenings would be nice).

ec99ed738083fc1ad4c9d85095e26e7e58372217 contrib: add tool to convert compact-serialized UTXO set to SQLite database (Sebastian Falbesoner)
Pull request description:
## Problem description
There is demand from users to get the UTXO set in form of a SQLite database (#24628). Bitcoin Core currently only supports dumping the UTXO set in a binary _compact-serialized_ format, which was crafted specifically for AssumeUTXO snapshots (see PR #16899), with the primary goal of being as compact as possible. Previous PRs tried to extend the `dumptxoutset` RPC with new formats, either in human-readable form (e.g. #18689, #24202), or most recently, directly as SQLite database (#24952). Both are not optimal: due to the huge size of the ever-growing UTXO set with already more than 80 million entries on mainnet, human-readable formats are practically useless, and very likely one of the first steps would be to put them in some form of database anyway. Directly adding SQLite3 dumping support on the other hand introduces an additional dependency to the non-wallet part of bitcoind and the risk of increased maintenance burden (see e.g. https://github.com/bitcoin/bitcoin/pull/24952#issuecomment-1163551060, https://github.com/bitcoin/bitcoin/issues/24628#issuecomment-1108469715).
## Proposed solution
This PR follows the "external tooling" route by adding a simple Python script for achieving the same goal in a two-step process (first create compact-serialized UTXO set via `dumptxoutset`, then convert it to SQLite via the new script). Executive summary:
- single file, no extra dependencies (sqlite3 is included in Python's standard library [1])
- ~150 LOC, mostly deserialization/decompression routines ported from the Core codebase and (probably the most difficult part) a little elliptic curve / finite field math to decompress pubkeys (essentialy solving the secp256k1 curve equation y^2 = x^3 + 7 for y given x, respecting the proper polarity as indicated by the compression tag)
- creates a database with only one table `utxos` with the following schema:
```(txid TEXT, vout INT, value INT, coinbase INT, height INT, scriptpubkey TEXT)```
- the resulting file has roughly 2x the size of the compact-serialized UTXO set (this is mostly due to encoding txids and scriptpubkeys as hex-strings rather than bytes)
[1] note that there are some rare cases of operating systems like FreeBSD though, where the sqlite3 module has to installed explicitly (see #26819)
A functional test is also added that creates UTXO set entries with various output script types (standard and also non-standard, for e.g. large scripts) and verifies that the UTXO sets of both formats match by comparing corresponding MuHashes. One MuHash is supplied by the bitcoind instance via `gettxoutsetinfo muhash`, the other is calculated in the test by reading back the created SQLite database entries and hashing them with the test framework's `MuHash3072` module.
## Manual test instructions
I'd suggest to do manual tests also by comparing MuHashes. For that, I've written a go tool some time ago which would calculate the MuHash of a sqlite database in the created format (I've tried to do a similar tool in Python, but it's painfully slow).
```
$ [run bitcoind instance with -coinstatsindex]
$ ./src/bitcoin-cli dumptxoutset ~/utxos.dat
$ ./src/bitcoin-cli gettxoutsetinfo muhash <block height returned in previous call>
(outputs MuHash calculated from node)
$ ./contrib/utxo-tools/utxo_to_sqlite.py ~/utxos.dat ~/utxos.sqlite
$ git clone https://github.com/theStack/utxo_dump_tools
$ cd utxo_dump_tools/calc_utxo_hash
$ go run calc_utxo_hash.go ~/utxos.sqlite
(outputs MuHash calculated from the SQLite UTXO set)
=> verify that both MuHashes are equal
```
For a demonstration what can be done with the resulting database, see https://github.com/bitcoin/bitcoin/pull/24952#pullrequestreview-956290477 for some example queries. Thanks go to LarryRuane who gave me to the idea of rewriting this script in Python and adding it to `contrib`.

5453e66fd91c303d04004d861ecad183ff177823 Fix nonsensical -noseednode behavior (Ryan Ofsky)
Pull request description:
The PR changes behavior of negated `-noseednode`, `-nobind`, `-nowhitebind`, `-norpcbind`, `-norpcallowip`, `-norpcwhitelist`, `-notest`, `-noasmap`, `-norpcwallet`, `-noonlynet`, and `-noexternalip` options, so negating these options just clears previously specified values doesn't have other side effects.
Negating options on the command line can be a useful way of resetting options that may have been set earlier in the command line or config file. But before this change, negating these options wouldn't fully reset them, and would have confusing and undocumented side effects (see commit descriptions for details). Now, negating these options just resets them and behaves the same as not specifying them.
Motivation for this PR is to fix confusing behaviors and also to remove incorrect usages of the `IsArgSet()` function. Using `IsArgSet()` tends to lead to negated option bugs in general, but it especially causes bugs when used with list settings returned by `GetArgs()`, because when these settings are negated, `IsArgSet()` will return true but `GetArgs()` will return an empty list. This PR eliminates all uses of `IsArgSet()` and `GetArgs()` together, and followup PR #17783 makes it an error to use `IsArgSet()` on list settings, since calling `IsArgSet()` is never actually necessary. Most of the changes here were originally made in #17783 and then moved here to be easier to review and avoid a dependency on #16545.

fa8e0956c23789fb819ad1b31377711df091ec1b rpc: Remove deprecated dummy alias for listtransactions::label (MarcoFalke)
Pull request description:
The RPC arg is not a dummy, but a label, so offering an undocumented alias is inconsistent with all other label interfaces and confusing at best, if not entirely unused.
Fix it by removing the deprecated alias.
This pull is a breaking change, but it should be limited, because it only affects someone using the deprecated named arg on this RPC. I can't imagine anyone doing this, because in all other places where label args are accepted, they are called `label`. If someone really didn't use `label` here as named arg, it would be trivial and less confusing for them to fix it up.
