a96b84cb1b fuzz: Abort when calling system time without setting mock time (marcofleon)
ff21870e20 fuzz: Add SetMockTime() to necessary targets (marcofleon)
Pull request description:
This PR expands the `CheckGlobals` utility that was introduced in https://github.com/bitcoin/bitcoin/pull/31486 and should help with fuzz stability (https://github.com/bitcoin/bitcoin/issues/29018).
System time shouldn't be used when running a fuzz test, as it is likely to introduce instability (non-determinism). This PR identifies and fixes the targets that were calling system time without setting mock time at the start of an iteration.
Removing`SetMockTime()` from any one of these targets should result in a crash and a message describing the issue.

fd2d96d908 build, test: Build `db_tests.cpp` regardless of `USE_BDB` (Hennadii Stepanov)
Pull request description:
When the building of `db_tests.cpp` was made conditional on `USE_BDB` in commit a58b719cf7, all `db_tests` were indeed specific to BDB wallets.
However, the tests have since been [extended](ba616b932c) to include SQLite wallets as well.
On the master branch @ 433412fd84, tests specific to SQLite wallets are not built and run if configured with `WITH_BDB=OFF` (the default option).
This PR resolves this issue by guarding BDB-specific code in `db_tests.cpp` and ensuring this source file is compiled regardless of the `WITH_BDB` option.

589ed1a8ea wallet: migration, avoid loading wallet after failure when it wasn't loaded before (furszy)
Pull request description:
Fixes#31447.
During migration failure, only load wallet back into memory when the wallet was
loaded prior to migration. This fixes the case where BDB is not supported, which
implies that no legacy wallet can be loaded into memory due to the lack of db
writing functionality.
Link to error description https://github.com/bitcoin/bitcoin/issues/31447#issuecomment-2528757140.
This PR also improves migration backup related comments to better document the
current workflow.

1ea7e45a1f test: raise explicit error if any of the needed release binaries is missing (Sebastian Falbesoner)
Pull request description:
If the `releases` directory exists, but still only a subset of the necessary previous release binaries are available, the test fails by throwing an exception (sometimes leading to follow-up exceptions like `AssertionError: [node 0] Error: no RPC connection`) and printing out a stack trace, which can be confusing and at a first glance suggests that the node crashed or some alike.
Improve this by checking and printing out *all* of the missing release binaries and failing with an explicit error in this case. Also add an info on how to download previous releases binaries. Noticed while testing #30328.
Can be tested by e.g.
```
$ rm -rf ./releases
$ ./test/get_previous_releases.py -b
$ rm -rf ./releases/v28.0/
$ ./build/test/functional/wallet_migration.py

On FreeBSD, the `shasum` utility is provided by the `perl5` port, which
is not part of the base system and must be installed separately.
Note that this requirement is currently not documented in
`depends/README.md`.
This change switches to using the `sha256sum` utility, which is included
in the base system.
When the behavior was changes in a previous commit (caching `GetSerializeSize` and avoiding `AutoFile.tell`), (static)asserts were added to make sure the behavior was kept - to make sure reviewers and CI validates it.
We can safely remove them now.
Logs were also slightly modernized since they were trivial to do.

Similarly, `WriteBlockToDisk` wasn't really extracting a meaningful subset of the `SaveBlockToDisk` functionality, it's tied closely to the only caller (needs the header size twice, recalculated block serializes size, returns multiple branches, mutates parameter).
The inlined code should only differ in these parts (modernization will be done in other commits):
* renamed `blockPos` to `pos` in `SaveBlockToDisk` to match the parameter name;
* changed `return false` to `return FlatFilePos()`.
Also removed remaining references to `SaveBlockToDisk`.

`UndoWriteToDisk` wasn't really extracting a meaningful subset of the `WriteUndoDataForBlock` functionality, it's tied closely to the only caller (needs the header size twice, recalculated undo serializes size, returns multiple branches, modifies parameter, needs documentation).

* renamed `_pos` to `pos` in `WriteUndoDataForBlock` to match the parameter name;

(total_cache / 4) + (1 << 23) is at least 8 MiB and nMaxCoinsDBCache is
also 8 MiB, so the minimum between the two will always be
nMaxCoinsDBCache. This is just a simplification and not changing the

The return type of `std::forward` depends on the template type, and can not be recovered from the args. Attempting to do so will result in a compile failure. For example, `make_secure_unique<std::string>(std::string{});` does not compile on current master, but does with this pull.

Now that we track all announcers of an orphan, it's not helpful to
consider an orphan provided by a peer that didn't send us this parent.
It can only hurt our chances of finding the right orphan when there are
multiple candidates.
Adapt the 2 tests in p2p_opportunistic_1p1c.py that looked at 1p1c
packages from different peers. Instead of checking that the right peer
is punished, we now check that the package is not submitted. We can't
use the functional test to see that the package was not considered
because the behavior is indistinguishable (except for the logs).
This means we no longer return parents we already have in the
m_unique_parents result from MempoolRejectedTx.
We need to separate the loop that checks AlreadyHave parents from the
loop that adds parents as announcements, because we may do the latter
loop multiple times for different peers.
Add ability to add and track multiple announcers per orphan transaction,
erasing announcers but not the entire orphan.
The tx creation code in orphanage_tests needs to be updated so that each
tx is unique, because the CountOrphans() check assumes that calling
EraseForPeer necessarily means its orphans are deleted.
Unused for now.
Needed for a later commit adding logic to ask the TxRequestTracker for a
list of announcers. These announcers should know the parents of the
transaction they announced.
e8f0e6efaf lint: output-only - Avoid repeated arrows, trim (Hodlinator)
fa9aacf614 lint: Move assertion linter into lint runner (MarcoFalke)
Pull request description:
On failure, this makes the output more consistent with the other linters. Each failure will be marked with an '⚠️ ' emoji and explanation, making it easier to spot.
Also, add --line-number to the filesystem linter.
Also, add newlines after each failing check, to visually separate different failures from each other.
