f1a0314c537791f202dfb7c1209f0e04ba7988c3 gui: change combiner for signals to optional_last_value (Cory Fields)
Pull request description:
[`optional_last_value`](https://www.boost.org/doc/libs/1_73_0/doc/html/boost/signals2/optional_last_value.html), which does not throw, has replaced `last_value` as
Boosts default combiner. Besides being better supported, it also doesn't
trigger gcc's `-Wmaybe-unitialized` warning, presumably because exceptions no
longer bubble-up out of signals:

The change in default happened in [Boost 1.39.0](https://www.boost.org/users/history/version_1_39_0.html) (along with the introduction of the Signals2 library.
More information is also available here https://www.boost.org/doc/libs/1_73_0/doc/html/signals2/rationale.html#id-1.3.36.9.4:
> The default combiner for Boost.Signals2 has changed from the last_value combiner used by default in the original Boost.Signals library.
> This is because last_value requires that at least 1 slot be connected to the signal when it is invoked (except for the last_value<void> specialization).
> In a multi-threaded environment where signal invocations and slot connections and disconnections may be happening concurrently, it is difficult to fulfill this requirement. When using optional_last_value, there is no requirement for slots to be connected when a signal is invoked, since in that case the combiner may simply return an empty boost::optional.

140a49ce5e547a1b520a7cd063af8308184e7cbf test: check that pruneblockchain RPC fails for future block or timestamp (Sebastian Falbesoner)
Pull request description:
This PR adds missing test coverage for the `pruneblockchain` RPC for the case that a future block or timestamp is passed:
8c0bd871fc/src/rpc/blockchain.cpp (L1101)8c0bd871fc/src/rpc/blockchain.cpp (L1111)
Note that the test method `manual_test` gets called twice, once each with `use_timestamp` set to True/False, respectively. Depending on that, the helper function `height` either converts the passed block height to the timestamp of that block, or just returns it without modification.
The other tests for failures in this RPC are also changed to be more detailled ("Cannot prune blocks because node is not in prune mode", "Negative block height"), as I don't think there is any value in just checking a sub-string. If there is ever an error with the same sub-string is introduced, it's not clear which error is exactly checked with the test, so it makes sense to be as specific as possible.

Pull request description:
Add `std::locale::global` to list of locale dependent functions in `lint-locale-dependence.sh`.
We currently flag `setlocale(...)` as locale dependent, but prior to this commit we didn't flag
`std::locale::global(...)` as such.
In addition to setting the global C++ locale `std::locale::global(...)` also does the equivalent of `std::setlocale(LC_ALL, ...);`.
Thus the functionality of `std::locale::global(...)` is a superset of `setlocale(...)` :)

5db506ba5943868cc2c845f717508739b7f05714 tests: Add option --valgrind to run nodes under valgrind in the functional tests (practicalswift)
Pull request description:
What is better than fixing bugs? Fixing entire bug classes of course! :)
Add option `--valgrind` to run the functional tests under Valgrind.
Regular functional testing under Valgrind would have caught many of the uninitialized reads we've seen historically.
Let's kill this bug class once and for all: let's never use an uninitialized value ever again. Or at least not one that would be triggered by running the functional tests! :)
My hope is that this addition will make it super-easy to run the functional tests under Valgrind and thus increase the probability of people making use of it :)
Hopefully `test/functional/test_runner.py --valgrind` will become a natural part of the pre-release QA process.
**Usage:**
```
$ test/functional/test_runner.py --help
…
--valgrind run nodes under the valgrind memory error detector:
expect at least a ~10x slowdown, valgrind 3.14 or
later required
```
**Live demo:**
First, let's re-introduce a memory bug by reverting the recent P2P uninitialized read bug fix from PR #17624 ("net: Fix an uninitialized read in ProcessMessage(…, "tx", …) when receiving a transaction we already have").
```
$ git diff
diff --git a/src/consensus/validation.h b/src/consensus/validation.h

const std::string &reject_reason="",
```
Second, let's test as normal without Valgrind:
```
$ test/functional/p2p_segwit.py -l INFO

Third, let's test with `--valgrind` and see if the test fail (as we expect) when the unitialized value is used:
```

9743432034586385cfef87df4b377c255ed0cba8 Fix bug where duplicate PSBT keys are accepted (John L. Jegutanis)
Pull request description:
As per the BIP 174 spec a PSBT key cannot be duplicated,
however the current code accepts key duplication.
The PSBT key/value entries can be duplicated when the value
is `empty()` or `IsNull()` for `CScript` or `CTxOut` respectively
and if those key/value entries are serialized before the non-empty ones.
For example, the following PSBT, included in the test vectors,
contains a duplicate field:
```
// magic
70736274ff
// global tx
//// key
0100
//// value
2a02000000000140420f000000000017a9146e91b72d5593e7d4391e2ff44e91e985c31641f08700000000
//// separator
00
// no inputs
// outputs
//// key PSBT_OUT_WITNESSSCRIPT

//// value (empty script)

Pull request description:
This PR improves `contrib/devtools/copyright_header.py` script and adds copyright headers to the files in `src` and `test` directories with two exceptions:
- [`src/reverse_iterator.h`](https://github.com/bitcoin/bitcoin/blob/master/src/reverse_iterator.h) (added to exceptions)
- [`src/test/fuzz/FuzzedDataProvider.h`](https://github.com/bitcoin/bitcoin/blob/master/src/test/fuzz/FuzzedDataProvider.h) (added to exceptions)
On master 5622d8f3156a293e61d0964c33d4b21d8c9fd5e0:
```
$ ./contrib/devtools/copyright_header.py report . | grep zero
25 with zero copyrights
```
With this PR:
