CBlockIndex's no longer live in the heap as of the previous commit.

Merge bitcoin/bitcoin#24343: Add descriptor_tests covering tr(), and fix minor bugs
0683f377e1 Add tr() descriptor unit tests (Pieter Wuille)
4b2e31a7ae Bugfix: make ToPrivateString work with x-only keys (Pieter Wuille)
18ad54c3b2 Bugfix: set x-only flag when inferring pk() inside tr() (Pieter Wuille)

Pull request description:

  This fixes two bugs in the current logic for `tr()` descriptors:
  * ToPrivateString does not always work, because the provided private key may mismatch the parity of the x-only public key.
  * The descriptors inferred for `pk()` inside `tr()` have the wrong x-only flag, leading to such descriptors generating the wrong scriptPubKey (roundtripping through ToString does fix it however, so this seems unobservable in the current code).

  These were discovered while adding unit tests to descriptor_tests that cover various aspects of `tr()` descriptors, which are now also added here.

Merge bitcoin/bitcoin#24349: fuzz: Split script formatting from script fuzz target
fae3f17823 fuzz: Split script formatting from script fuzz target (MarcoFalke)

Pull request description:

  This is a follow-up to commit 9237bdaac1.

  The target was improved a bit, but is still taking enormously long. See for example 4096 seconds in https://cirrus-ci.com/task/5153886888525824?logs=ci#L4451.

  Most of the time is spent formatting the script. See the flamegraph: ![flame](https://user-images.githubusercontent.com/6399679/154052491-ad868078-42e6-4d85-9c77-c2e7e8291a9f.png)

  Thus, I suggest to split up the formatting into a new target. This will:

  * Allow more fuzz cycles in the `script` target when exploring the search space with the fuzz engine
  * Hopefully allow to reduce the fuzz inputs in `qa-assets` without losing coverage

1f46b6e46e util: Work around libstdc++ create_directories issue
Work around libstdc++ issue [PR101510] with create_directories where the
leaf already exists as a symlink. Fixes #24257, introduced by the switch
to `std::filesystem`. It is meant to be more thorough than #24266, which
only worked around one instance of the problem.

The issue was fixed upstream in
https://gcc.gnu.org/git/?p=gcc.git;a=commit;h=124eaa50e0a34f5f89572c1aa812c50979da58fc,
but unfortunately we'll have to carry a fix for it for a while.

This introduces a function `fs::create_directories` which wraps
`std::filesystem::create_directories`. This allows easiliy reverting the
workaround when it is no longer necessary.

d4999d40b9 util: Revert back MoveFileExW call for MinGW-w64 (Hennadii Stepanov)

Pull request description:

  Unfortunately, bitcoin/bitcoin#24308 introduced a [regression](https://github.com/bitcoin/bitcoin/pull/24308#issuecomment-1037259386) for mingw builds.

  The root of the problem is a broken implementation of [`std::filesystem::rename`](https://en.cppreference.com/w/cpp/filesystem/rename). In particular, the expected behavior
  > If `old_p` is a non-directory file, then `new_p` must be ... existing non-directory file: `new_p` _is first deleted_...

  fails with the "File exists" error.

  This PR reverts back the `MoveFileExW` call, and adds the [suggested](https://github.com/bitcoin/bitcoin/pull/24308#pullrequestreview-878832906) unit test.

net: open p2p connections to nodes that listen on non-default ports
By default, for mainnet, the p2p listening port is 8333. Bitcoin Core
has a strong preference for only connecting to nodes that listen on that
port.

Remove that preference because connections over clearnet that involve
port 8333 make it easy to detect, analyze, block or divert Bitcoin p2p
traffic before the connection is even established (at TCP SYN time).

  Fix windows test cases broken in #20744, by passing normalized path arguments to fs::equivalent, fs::exists, and fs::is_directory, instead of non-normalized arguments. Also re-enable the tests.

80cd64e842 Re-enable util_datadir check disabled in #20744
This should also fix an assert error if a -datadir with a trailing slash
is used on windows. This appears to be a real error and regression
introduced with #20744.

On windows (or at least wine), fs calls that actuallly access the
filesystem like fs::equivalent or fs::exists seem to treat directory
paths with trailing slashes as not existing, so it's necessary to
normalize these paths before using them. This fix adds a
path::lexically_normal() call to the failing assert so it passes.

  Two changes (that also make sense on their own) to remove the file-wide sanitizer suppression:

  * `FindByte` no longer takes a `char`, but an `uint8_t`, after commit 196b459920.
  * The `key` vector of unsigned chars can be removed and inlined as initializer-list. This avoids a bunch of verbose code like `clear()` and `push_back` of `char`s.

Merge bitcoin/bitcoin#23508: Add getdeploymentinfo RPC

fd826130a0 rpc: move softfork info from getblockchaininfo to getdeploymentinfo (Anthony Towns)

Pull request description:

  The aim of this PR is to improve the ability to monitor soft fork status. It first moves the softfork section from getblockchaininfo into a new RPC named getdeploymentinfo, which is then also able to query the status of forks at an arbitrary block rather than only at the tip. In addition, bip9 status is changed to indicate the status of the given block, rather than just for the next block, and an additional field is included to indicate whether each block in the signalling period signaled.

net: use Sock in CNode
Change `CNode` to use a pointer to `Sock` instead of a bare `SOCKET`.
This will help mocking / testing / fuzzing more code.

Merge bitcoin/bitcoin#23438: refactor: Use spans of std::byte in serialize
fa5d2e678c Remove unused char serialize (MarcoFalke)
fa24493d63 Use spans of std::byte in serialize (MarcoFalke)
fa65bbf217 span: Add BytePtr helper (MarcoFalke)

Pull request description:

  This changes the serialize code (`.read()` and `.write()` functions) to take a `Span` instead of a pointer and size. This is a breaking change for the serialize interface, so at no additional cost we can also switch to `std::byte` (instead of using `char`).

  The benefits of using `Span`:
  * Less verbose and less fragile code when passing an already existing `Span`(-like) object to or from serialization

  The benefits of using `std::byte`:
  * `std::byte` can't accidentally be mistaken for an integer

  The goal here is to only change serialize to use spans of `std::byte`. If needed, `AsBytes`,  `MakeUCharSpan`, ... can be used (temporarily) to pass spans of the right type.

  Other changes that are included here:

  * [#22167](https://github.com/bitcoin/bitcoin/pull/22167) (refactor: Remove char serialize by MarcoFalke)
  * [#21906](https://github.com/bitcoin/bitcoin/pull/21906) (Preserve const in cast on CTransactionSignatureSerializer by promag)

Pull request description:

  Issues:

  - `CBlockIndex` member functions `GetBlockPos()`, `GetUndoPos()`, `IsAssumedValid()`, `RaiseValidity()`, and `IsValid()` and block storage functions `WriteUndoDataForBlock()` and `IsBlockPruned()` are missing thread safety lock annotations to help ensure that they are called with mutex cs_main to avoid bugs like #22895. Doing this also enables the next step:

  - `CBlockIndex::nStatus` may be racy, i.e. potentially accessed by multiple threads, see #17161. A solution is to guard it by cs_main, along with fellow data members `nFile`, `nDataPos` and `nUndoPos`.

  This pull:

  - adds thread safety lock annotations for the functions listed above
  - guards `CBlockIndex::nStatus`, `nFile`, `nDataPos` and `nUndoPos` by cs_main

  How to review and test:
  - debug build with clang and verify there are no `-Wthread-safety-analysis` warnings
  - review the code to verify each annotation or lock is necessary and sensible, or if any are missing
  - look for whether taking a lock can be replaced by a lock annotation instead
  - for more information about Clang thread safety analysis, see
      - https://clang.llvm.org/docs/ThreadSafetyAnalysis.html

      - https://github.com/bitcoin/bitcoin/blob/master/doc/developer-notes.md#threads-and-synchronization

  Mitigates/potentially closes #17161.
