Now that m_txrequest and m_recent_confirmed_transactions are guarded by
the same mutex, there is no benefit to processing them separately.
Instead, just loop through pblock->vtx once.

Pull request description:
The current `test-security-check` script is hard to understand, and change (i.e https://github.com/bitcoin/bitcoin/pull/29987/files#diff-52aa0cda44721f089e53b128cb1232a876006ef257b211655456b17dfb2ec712); tests are also not done in isolation (when-possible). Fix that, and add missing checks. Simplifies future toolchain/security/hardening changes.

Pull request description:
See #27463 for full project tracking.
This contains the first few commits of #30110, which require some thinking about thread safety in review.
- Introduce a new `m_tx_download_mutex` which guards the transaction download data structures including `m_txrequest`, the rolling bloom filters, and `m_orphanage`. Later this should become the mutex guarding `TxDownloadManager`.
- `m_txrequest` doesn't need to be guarded using `cs_main` anymore
- `m_recent_confirmed_transactions` doesn't need its own lock anymore
- `m_orphanage` doesn't need its own lock anymore
- Adds a new `ValidationInterface` event, `ActiveTipChanged`, which is a synchronous callback whenever the tip of the active chainstate changes.
- Flush `m_recent_rejects` and `m_recent_rejects_reconsiderable` on `ActiveTipChanged` just once instead of checking the tip every time `AlreadyHaveTx` is called. This should speed up calls to that function (no longer comparing a block hash each time) and removes the need to lock `cs_main` every time it is called.
Motivation:
- These data structures need synchronization. While we are holding `m_tx_download_mutex`, these should hold:
- a tx hash in `m_txrequest` is not also in `m_orphanage`
- a tx hash in `m_txrequest` is not also in `m_recent_rejects` or `m_recent_confirmed_transactions`
- In the future, orphan resolution tracking should also be synchronized. If a tx has an entry in the orphan resolution tracker, it is also in `m_orphanage`, and not in `m_txrequest`, etc.
- Currently, `cs_main` is used to e.g. sync accesses to `m_txrequest`. We should not broaden the scope of things it locks.
- Currently, we need to know the current chainstate every time we call `AlreadyHaveTx` so we can decide whether we should update it. Every call compares the current tip hash with `hashRecentRejectsChainTip`. It is more efficient to have a validation interface callback that updates the rejection filters whenever the chain tip changes.

Instead of constructing a new class every time a file operation is done,
construct them once for each of the undo and block file when a new
BlockManager is created.
In future, this might make it easier to introduce an abstract block
store.
SetHex is fragile, because it accepts any non-hex input or any length of
input, without error feedback. This can lead to issues when the input is
truncated or otherwise corrupted.
Document the problem by renaming the method.
In the future, the fragile method should be removed from the public
interface.

f0eeee2dc1329b0647df09bea9ccc0395bb82698 test: Add test for TxidFromString() behavior (Ryan Ofsky)
Pull request description:
### Problem
Prior to this, `TxidFromString()` was passing `string_view::data()` into `uint256S()` which meant it would only receive the a naked `char*` pointer and potentially scan past the `string_view::length()` until it found a null terminator (or some other non-hex character).
Appears to have been a fully dormant bug as callers were either passing a string literal or `std::string` directly to `TxidFromFromString()`, meaning a null terminator always existed at `pointer[length()]`. Bug existed since original merge of `TxidFromString()`.
### Solution
Make `uint256S()` (and `base_blob::SetHex()`) take and operate on `std::string_view` instead of `const char*` and have `TxidFromString()` pass that in.

29eafd5733d77b3e8f3f3ab6cd65c61ac0e8536b rpc: doc: use "output script" terminology consistently in "asm"/"hex" results (Sebastian Falbesoner)
Pull request description:
The wording "public key script" was likely chosen as a human-readable form of the technical term `scriptPubKey`, but it doesn't seem to be really widespread. Replace it by the more (probably most?) common term "output script" instead. Note that the argument for the `decodescript` RPC is not necessarily an output script (it could e.g. be also a redeem script), so in this case we just stay generic and use "script".
See also the draft BIP "Terminology for Transaction Components" (https://github.com/murchandamus/bips/blob/2022-04-tx-terminology/bip-tx-terminology.mediawiki) from murchandamus which suggests to use "output script" as well.
Affects the help text of the following RPCs:
- decodepsbt
- decoderawtransaction
- decodescript
- getblock (if verbosity=3)
- getrawtransaction (if verbosity=2,3)
- gettxout

Using GCC 11 for the macOS build hasn't been required since #21778, and
at this point, given a toolchain is still needed (#30206), it makes more
sense to (re-)use 12, rather than make all builders compile another
GCC toolchain.
Prior to this, passing string_view::data() into uint256S() meant the latter would only receive the a naked char* pointer and potentially scan past the string_view::length() until it found a null terminator (or some other non-hex character).
Appears to have been a fully dormant bug as callers were either passing a string literal or std::string directly to TxidFromFromString(), meaning null terminator always existed at pointer[length()].

Pull request description:
`PickValue` will advance a begin iterator on the `outpoints` set, which is expensive, because it only has a `++` operator. As it is called in a loop of `num_in` (~`outpoints.size()`), the runtime is `O(outpoints.size() ^ 2)`.
Fix it by making the runtime linear.

Pull request description:
Fixes https://github.com/bitcoin/bitcoin/issues/30496
Seems odd to sometimes do an out-of-tree build (via `./ci/lint_imagefile`, see `test/lint/README.md`) and sometimes not (via Cirrus CI, see `./ci/lint_run_all.sh`).
Fix it by doing an out-of-tree build consistently in the same location.
Also, fix `$CI_RETRY_EXE`, while touching this.

Previous code was confusing and brittle. For example, the full import
"source ./ci/test/00_setup_env.sh" and $PATH overwrite was not needed.
Fix it by simply copying the exe to /ci_retry and use that in
$CI_RETRY_EXE.
This is also a fix, because previously ci/lint_imagefile did use an
empty $CI_RETRY_EXE.

Pull request description:
This PR includes changes split from https://github.com/bitcoin/bitcoin/pull/30454. They improve the functional test framework, allowing users to [run individual functional tests](https://github.com/hebasto/bitcoin/issues/146) from the build directory in the new CMake-based build system.
This functionality is not available for out-of-source builds using the current Autotools-based build system, which always requires write permissions for the source directory. Nevertheless, this PR can be tested as suggested in https://github.com/bitcoin/bitcoin/pull/30463#issuecomment-2232618421:
1. Make an out-of-source build:
```
$ ./autogen.sh
$ mkdir ../build && cd ../build
$ ../bitcoin/configure
$ make
```
2. Create a symlink in the build directory to a functional test:
```
$ ln --symbolic ../../../bitcoin/test/functional/wallet_disable.py ./test/functional/
```
3. Run this symlink:
```
$ ./test/functional/wallet_disable.py
```
The last command fails on the master branch:
```
Traceback (most recent call last):
File "/home/hebasto/git/build/./test/functional/wallet_disable.py", line 31, in <module>

7703884ab19cd7ffddc5c52ba57dec82fbc8dc2b Fix MSVC warning C4273 "inconsistent dll linkage" (Hennadii Stepanov)
Pull request description:
Broken out of https://github.com/bitcoin/bitcoin/pull/30454.
When using CMake, the user can select the MSVC runtime library to be:
1) Statically-linked (with the corresponding `x64-windows-static` vcpkg triplet) or
2) Dynamically-linked (with the corresponding `x64-windows` vcpkg triplet)
In the latter case, the compiler emits the [C4273](https://learn.microsoft.com/en-us/cpp/error-messages/compiler-warnings/compiler-warning-level-1-c4273) warning.
As the "Necessary on some platforms" comment does not apply to MSVC, skip the declaration for MSVC.
The MSVC build system in the master branch supports the statically-linked runtime only: ed739d14b5/build_msvc/common.init.vcxproj.in (L65)

As the "Necessary on some platforms" comment does not apply to MSVC,
skip the declaration for MSVC.
The body of the fuzz test should ideally be a pure function. If data is
persisted in the cache over many iterations, and there is a crash,
reproducing it from the input might be difficult.
