We comment out a newly-added assert from the Bitcoin
side, because it's unclear how to replicate it
correctly in Elements.

When PR 1022 was merged, an & got dropped from the declarations of the two
"fStall" out-parameters, rendering them unused (and triggering a compiler
warning.) Restore them, restoring the functionality of #1022.

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.
```

fa8d4d9128 scripted-diff: Clarify CheckFinalTxAtTip name (MarcoFalke)
fa4e30b0f3 policy: Remove unused locktime flags (MarcoFalke)
Pull request description:
The locktime flags have many issues:
* They are passed in by a default argument, which is fragile. It has already lead to bugs like the one fixed in commit e30b6ea194.
* They are negative (signed), which doesn't make sense for flags (unsigned in general). According to the review comments when the code was added: "The max on the flags is a fairly weird operation." (https://github.com/bitcoin/bitcoin/pull/6566#issuecomment-150310861)
* No call site relies on the default argument and they all pass in a single compile-time constant, rendering most of the code dead and untested.
* The dead code calls `GetAdjustedTime` (network adjusted time), which has its own issues. See https://github.com/bitcoin/bitcoin/issues/4521
Fix all issues by removing them

ACK fa8d4d9128, agree the default arg `flags` is a massive footgun and just setting max flags is weird. Adding `AtTip` to the names makes sense to me, since they're both testing for *next* block and only ever used for {,re}addition to mempool.

faa1aec26b Remove confusing P1008R1 violation in ATMPArgs (MarcoFalke)
Pull request description:
The `= delete` doesn't achieve the stated goal and it is also redundant, since it is not possible to default construct the `ATMPArgs` type.

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.
```
The second commit demonstrates how this makes calls to `Unload()` to satisfy the address sanitizer unnecessary.

Pull request description:
Thread safety refactoring seen in #24177:
- replace re-acquiring lock cs_main with a thread safety annotation in UnloadBlockIndex()
- remove ChainstateManager::Reset(), as it is currently unused (can be reintroduced in the test utilities if needed for unit testing)

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:
This PR is a follow-up to the [#22902](https://github.com/bitcoin/bitcoin/pull/22902).
Previously, the tracepoint `utxocache:flush` was called, even when it was not flushing. So, the tracepoint is now scoped to write only when coins cache to disk.
