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

dce8c4c381 rpc: getblockfrompeer (Sjors Provoost)
b884ababc2 rpc: move Ensure* helpers to server_util.h (Sjors Provoost)
Pull request description:
This adds an RPC method to fetch a block directly from a peer. This can used to fetch stale blocks with lower proof of work that are normally ignored by the node (`headers-only` in `getchaintips`).
Usage:
```
bitcoin-cli getblockfrompeer HASH peer_n
```
Closes #20155
Limitations:
* you have to specify which peer to fetch the block from
* the node must already have the header

3333070208 refactor: Call type-solver earlier in decodescript (MarcoFalke)
fab0d998f4 style: Remove whitespace (MarcoFalke)
Pull request description:
The current logic is a bit confusing. First creating the `UniValue` return dict, then parsing it again to get the type as `std::string`.
Clean this up by using a strong type `TxoutType`. Also, remove whitespace.

As node operators are free to set their mempool policies however they
please, it's possible for package transaction(s) to already be in the
mempool. We definitely don't want to reject the entire package in that
case (as that could be a censorship vector).
We should still return the successful result to the caller, so add
another result type to MempoolAcceptResult.

Pull request description:
Similarly to how #18698 added `ProcessNewBlock()` and `ProcessNewBlockHeaders()` methods to the `ChainstateManager` class, this PR adds a new `ProcessTransaction()` method. Code outside validation no longer calls `AcceptToMemoryPool()` directly, but calls through the higher-level `ProcessTransaction()` method. Advantages:
- The interface is simplified. Calling code no longer needs to know about the active chainstate or mempool object, since `AcceptToMemoryPool()` can only ever be called for the active chainstate, and that chainstate knows which mempool it's using. We can also remove the `bypass_limits` argument, since that can only be used internally in validation.
- responsibility for calling `CTxMemPool::check()` is removed from the callers, and run automatically by `ChainstateManager` every time `ProcessTransaction()` is called.

This is not only cleaner but also helps make sure we are always using
the virtual size measure that includes the sigop weight heuristic (which
is the vsize the mempool would return).
f685a13bef doc: GetTransaction()/getrawtransaction follow-ups to #22383 (John Newbery)
abc57e1f08 refactor: move `GetTransaction(...)` to node/transaction.cpp (Sebastian Falbesoner)
Pull request description:
~This PR is based on #22383, which should be reviewed first~ (merged by now).
In [yesterday's PR review club session to PR 22383](https://bitcoincore.reviews/22383), the idea of moving the function `GetTransaction(...)` from src/validation.cpp to src/node/transaction.cpp came up. With this, the circular dependency "index/txindex -> validation -> index/txindex" is removed (see change in `lint-circular-dependencies.sh`). Thanks to jnewbery for suggesting and to sipa for providing historical background.
Relevant IRC log:
```
17:52 <jnewbery> Was anyone surprised that GetTransaction() is in validation.cpp? It seems to me that node/transaction.cpp would be a more appropriate place for it.
17:53 <raj_> jnewbery, +1
17:53 <stickies-v> agreed!
17:54 <glozow> jnewbery ya
17:54 <jnewbery> seems weird that validation would call into txindex. I wonder if we remove this function, then validation would no longer need to #include txindex
17:54 <sipa> GetTransaction predates node/transaction.cpp, and even the generic index framework itself :)
17:55 <sipa> (before 0.8, validation itself used the txindex)
17:55 <jnewbery> (and GetTransaction() seems like a natural sibling to BroadcastTransaction(), which is already in node/transaction.cpp)
17:55 <jnewbery> sipa: right, this is not meant as a criticism of course. Just wondering if we can organize things a bit more rationally now that we have better separation between things.
17:55 <sipa> jnewbery: sure, just providing background
17:56 <sipa> seems very reasonable to move it elsewhere now
```

78f4c8b98e prefer to use txindex if available for GetTransaction (Jameson Lopp)
Pull request description:
Fixes #22382
Motivation: prevent excessive disk reads if txindex is enabled.
Worth noting that this could be argued to be less of a bug and more of an issue of undefined behavior. If a user calls GetTransaction with the wrong block hash, what should happen?

Only allow "packages" with no conflicts, sorted in order of dependency,
and no more than 25 for now. Note that these groups of transactions
don't necessarily need to adhere to some strict definition of a package
or have any dependency relationships. Clients are free to pass in a
batch of 25 unrelated transactions if they want to.
