We don't need so much access to the internals of CCoinsCacheEntry, since many tests are just exercising invalid combinations this way.
This implies that `AddFlags` has private access now.
CCoinsCacheEntry provided general access to its internal flags state, even though in reality it could only be clean, fresh, dirty or fresh|dirty.
After it got dirtied we couldn't set the state back to clean by AddFlags(0) - tests were explicitly checking against that.
This commit cleans up the public interface to make this distinction cleaner and invalid behavior impossible instead of just checked by tests.
This includes the removal of redundant `inline` qualifiers (we're inside a struct).
Also renamed `self` to `pair` to simplify the upcoming commits.
Also modernized `EmplaceCoinInternalDANGER` since it was already modified.

When no build targets are specified, it is reasonable to expect the configuration step to succeed and produce a build system that does not build any targets.
This PR updates the code to ensure this behaviour:

b73d331937 dbwrapper: Bump max file size to 32 MiB (Maciej S. Szmigiero)
Pull request description:
The default max file size for LevelDB is 2 MiB, which results in the LevelDB compaction code generating ~4 disk cache flushes per second when syncing with the Bitcoin network.
These disk cache flushes are triggered by `fdatasync()` syscall issued by the LevelDB compaction code when reaching the max file size.
If the database is on a HDD this flush rate brings the whole system to a crawl.
It also results in very slow throughput since 2 MiB * 4 flushes per second is about 8 MiB / second max throughput, while even an old HDD can pull 100 - 200 MiB / second streaming throughput.
Increase the max file size for LevelDB to 128 MiB instead so the flush rate drops to about 1 flush / 2 seconds and the system no longer gets so sluggish.
The max file size value chosen also matches the `MAX_BLOCKFILE_SIZE` file size setting already used by the block storage.

The default max file size for LevelDB is 2 MiB, which results in the
LevelDB compaction code generating ~4 disk cache flushes per second when
syncing with the Bitcoin network.
These disk cache flushes are triggered by fdatasync() syscall issued by the
LevelDB compaction code when reaching the max file size.
If the database is on a HDD this flush rate brings the whole system to a
crawl.
It also results in very slow throughput since 2 MiB * 4 flushes per second
is about 8 MiB / second max throughput, while even an old HDD can pull
100 - 200 MiB / second streaming throughput.
Increase the max file size for LevelDB to 32 MiB instead so the flush rate
drops significantly and the system no longer gets so sluggish.
The new max file size value chosen is a compromise between the one that
works best for HDD and SSD performance, as determined by benchmarks done by
various people.

Pull request description:
The RPC command `scanblocks` provides a useful way to get a set of blockhashes that have activity relevant to a set of descriptors (`relevant_blocks`). However actually extracting the activity from those blocks is left as an exercise to the end user.
This process involves not only generating the (potentially ranged) set of scripts for the descriptor set on the client side (maybe via `deriveaddresses`), but then the user must retrieve each block's contents one-by-one using `getblock <hash>`, which is transmitted over a network link. And that's all before they perform the actual search over block content. There's even more work required to incorporate unconfirmed transactions.
This PR introduces an RPC `getdescriptoractivity` that [dovetails](https://bitcoin-irc.chaincode.com/bitcoin-core-dev/2024-08-16#1046393;) with `scanblocks` output, handling the process described above. Users specify the blockhashes (perhaps from `relevant_blocks`) and a set of descriptors; they are then given all spend/receive activity in that set of blocks.
This is a very useful tool when implementing lightweight wallets that want neither to require a third-party indexer like electrs, nor the overhead of creating and managing watch-only wallets in Core. This allows Core to be more easily used in a "stateless" manner by wallets, with potentially many nodes interchangeably acting as backends.

e8f50c5deb guix: swap moreutils for just sponge (fanquake)
Pull request description:
Switch to building the only `moreutils` utility we actually need (`sponge`). This results in having less unused stuff in the Guix environment (i.e all the other `moreutils` utilities), and, the dependency graph is simplified. i.e we no-longer have a dependency on `perl`, `docbook` etc, for this package.
Current `moreutils` dependency graph:
In the Guix env, `chronic`, `combine`, `errno`, `ifdata`, `ifne`, `isutf8`, `lckdo`, `mispipe`, `parallel`, `pee`, `ts`, `vidir`, `vipe` & `zrun` (plus their `*.real` variants) are removed.

With this patch it is possible to link against the static consensus library and produce a fully static executable.

This is not a pure refactor:
1. It slightly changes the log messages, as reflected in the test changes
2. It adds the IP address to all disconnect logging (when fLogIPs is set)
And under the hood suppoert single transactions
in AcceptPackage. This simplifies user experience
and paves the way for reducing number of codepaths
for transaction acceptance in the future.
