d45eb3964f test: compare BDB dumps of test framework parser and wallet tool (Sebastian Falbesoner)
01ddd9f646 test: complete BDB parser (handle internal/overflow pages, support all page sizes) (Sebastian Falbesoner)
Pull request description:
This PR adds missing features to our test framework's BDB parser with the goal of hopefully being able to read all legacy wallets that are created with current and past versions of Bitcoin Core. This could be useful both for making review of https://github.com/bitcoin/bitcoin/pull/26606 easier and to also possibly improve our functional tests for the wallet BDB-ro parser by additionally validating it with an alternative implementation. The second commits introduces a test that create a legacy wallet with huge label strings (in order to create overflow pages, i.e. pages needed for key/value data than is larger than the page size) and compares the dump outputs of wallet tool and the extended test framework BDB parser.
It can be exercised via `$ ./test/functional/tool_wallet.py --legacy`. BDB support has to be compiled in (obviously).
For some manual tests regarding different page sizes, the following patch can be used:
```diff

throw std::runtime_error(strprintf("BerkeleyDatabase: Error %d, can't open database %s", ret, strFile));
```
I verified that the newly introduced test passes with all valid page sizes between 512 and 65536.

Loading a wallet with conflicts without a chain (e.g. wallet tool and
migration) would previously result in an assertion due to -1 being both
a valid number of conflict confirmations, and the indicator that that
member has not been set yet.
2c0c6f4477 test: dedup file hashing using `sha256sum_file` helper (Sebastian Falbesoner)
Pull request description:
Rather than doing the open/read/hash-steps manually in the affected functional tests, we can just use the `sha256sum_file` helper from the utils module instead.
Note that for the tool_wallet.py test, the used hash is changed from sha1 to sha256, but as the only purpose is to detect file content changes, this doesn't matter. Also, the optimization using `memoryview` is overkill here, as the opened file has only a size of 24KiB and determining the hash via the helper doesn't take longer than a few hundred micro-seconds on my machine.

Instead of passing the datadir and chain name to os.path.join, just use
the existing properties, which are the same.

This change makes the `bitcoin-wallet` binary path customizable in the
same way how it can be done now with other ones, including `bitcoind`,
`bitcoin-cli` and `bitcoin-util`.
Rather than doing the open/read/hash-steps manually in the affected
functional tests, we can just use the `sha256sum_file` helper from the
utils module instead.
Note that for the tool_wallet.py test, the used hash is changed from
sha1 to sha256, but as the only purpose is to detect file content
changes, this doesn't matter. Also, the optimization using `memoryview`
is overkill here, as the opened file has only a size of 24KiB and
determining the hash doesn't take longer than a few hundred
micro-seconds on my machine.
Review note: The changes are complete, because self.options.descriptors
is set to None in parse_args (test_framework.py).
A value of None implies -disablewallet, see the previous commit.
So if a call to add_wallet_options is missing, it will lead to a test
failure when the wallet is compiled in.
The previous diff touched most files in ./test/, so bump the headers to
avoid having to touch them again for a bump later.

fa0b916971 scripted-diff: Use generate* from TestFramework (MarcoFalke)
Pull request description:
This is needed for #22567.
By using the newly added `generate*` member functions of the test framework, it paves the way to make it easier to implicitly call `sync_all` after block generation to avoid intermittent issues.
