Pull request description:
# Motivation
The main motivation of this change and only behavior change noticeable by user is to allow running `coinstatsindex` on pruned nodes as has been requested [here for example](https://twitter.com/benthecarman/status/1388170854140452870?s=20).
# Background
`coinstatsindex` on pruned nodes can be enabled in a much simpler than it is done here but it comes with downside. The ability to run `blockfilterindex`on pruned nodes was added in #15946 but it also added the `blockfilterindex` as a dependency to `validation` and it introduced two new circular dependencies. Enabling `coinstatsindex` on pruned nodes in a similar way would add it as a dependency as well and introduce another circular dependency.
Instead, this PR introduces a `m_prune_blockers` map to `BlockManager` as a flexible approach to block pruning. Entities like `blockfilterindex`, for example, can add a key and a height to block pruning over that height. These entities need to update that value to allow more pruning when they are ready.
# Alternative approach
Upon completing the first draft of this PR I found #19463 as an alternative that follows the same but follows a very different approach. I am listing the main differences here as I see them:
- Usage of globals
- Blocks pruning with a start and a stop height
- Can persist blockers across restarts
- Blockers can be set/unset via RPCs
Personally, I don't think any of these are necessary to be added here but if the general approach or specific features are more appealing to reviewers I am happy to change to a solution based on that PR or port over specific parts of it here.

Pull request description:
This PR replaces the macro `CHECK_NONFATAL` with an identity function.
I simplified the usage of `CHECK_NONFATAL` where applicable in `src/rpc`.
This function is useful in sanity checks for RPC and command-line interfaces.
Context: https://github.com/bitcoin/bitcoin/pull/24804#discussion_r846182474.
Also adds `UNREACHABLE_NONFATAL` macro.

Pull request description:
The only important commit is "Only load BlockMan in BlockMan member functions", everything else is all just small style changes.
Here's the commit message, reproduced:
```
This commit effectively splits the "load block index itself" logic from
"derive Chainstate variables from loaded block index" logic.
This means that BlockManager::LoadBlockIndex{,DB} will only load what's
relevant to the BlockManager.
```

Instead of having CBlockIndex's live on the heap, which requires manual
memory management, have them be owned by m_block_index. This means that
they will live and die with BlockManager.
A change to BlockManager::LookupBlockIndex:
- Previously, it was a const member function returning a non-const CBlockIndex*
- Now, there's are const and non-const versions of
BlockManager::LookupBlockIndex returning a CBlockIndex with the same
const-ness as the member function:
(e.g. const CBlockIndex* LookupBlockIndex(...) const)
See next commit for some weirdness that this eliminates.
The range based for-loops are modernize (using auto + destructuring) in
a future commit.

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.

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

On a period boundary, getdeploymentinfo (and previously getblockchaininfo)
would report the status and statistics for the next block rather than
the current block. Change this to always report the status/statistics
of the current block, but add status-next to report the status for the
next block.

A snapshot contains the utxo set, including the out value. To activate the snapshot, the hash needs to be calculated. As a side-effect, the total amount in the snapshot is calculated (as the sum of all out values), but never used. Instead of running into an integer overflow in an unused result, don't calculate the result in the first place.
Other code paths (using the active utxo set) can not run into an integer overflow, since the active utxo set is valid.
