A subsequent commit will add a .lock file to this dir at startup, meaning that
the blocksdir is never empty by the time the xor key is being read/written.
Ignore all hidden files when determining if this is the first run.

The chainstate caches are currently re-balanced on startup
even in the non-assumeutxo case, leading to the database being
needlessly re-opened and its cache re-allocated.
Similar to `InitCoinsCache` and `m_coinstip_cache_size_bytes` the
`m_coinsdb_cache_size_bytes` should be set in `InitCoinsDB`.
Together with only conservatively setting the cache values when a
assumeutxo chainstate is present, this allows for skipping the cache
re-balance during initialization in the normal non-assumeutxo case.

There is no way to report a close error from `AutoFile` destructor.
Such an error could be serious if the file has been written to because
it may mean the file is now corrupted (same as if write fails).
So, change all users of `AutoFile` that use it to write data to
explicitly close the file and handle a possible error.

1b41d45d46 wallet: bugfix: ensure atomicity in settings updates (ismaelsadeeq)
Pull request description:
This PR fixes#30620.
As outlined in the issue, creating two wallets with `load_on_startup=true` simultaneously results in only one wallet being added to the startup file.
The current issue arises because the wallet settings update process involves:
1. Obtaining the settings value while acquiring the settings lock.
2. Modifying the settings value.
3. Overwriting the settings value while acquiring the settings lock again.
This sequence is not thread-safe. Different threads could modify the same base value simultaneously, overwriting data from other workers without realizing it.
The PR attempts to fix this by modifying the chain interface's `updateRwSetting` method to accept a function that will be called with the settings reference. This function will either update or delete the setting and return an enum indicating whether the settings need to be overwritten in this or not.
Additionally, this PR introduces two new methods to the chain interface:
- `overwriteRwSetting`: This method replaces the setting with a new value.
Used in `VerifyWallets`
- `deleteRwSettings`: This method completely erases a specified setting.
This method is currently used only in `overwriteRwSetting`.
These changes ensure that updates are race-free across all clients.

- Settings updates were not thread-safe, as they were executed in
three separate steps:
1) Obtain settings value while acquiring the settings lock.
2) Modify settings value.
3) Overwrite settings value while acquiring the settings lock.
This approach allowed concurrent threads to modify the same base value
simultaneously, leading to data loss. When this occurred, the final
settings state would only reflect the changes from the last thread
that completed the operation, overwriting updates from other threads.
Fix this by making the settings update operation atomic.
- Add test coverage for this behavior.

00618e8745 assumeutxo: Drop block height from metadata (Fabian Jahr)
Pull request description:
Fixes https://github.com/bitcoin/bitcoin/issues/30514 which has more context and shows how the issue can be reproduced. Since the value in question is removed, there is no test to add to reproduce anything.
This is an alternative approach to #30516 with much of the [code being suggested there](https://github.com/bitcoin/bitcoin/pull/30516#discussion_r1689146902).

2925bd537c refactor: use c++20 std::views::reverse instead of reverse_iterator.h (stickies-v)
Pull request description:
C++20 introduces [`std::ranges::views::reverse`](https://en.cppreference.com/w/cpp/ranges/reverse_view), which allows us to drop our own `reverse_iterator.h` implementation and also makes it easier to chain views (even though I think we currently don't use this).
