The `on_addr` functionality of `AddrReceiver` tests logic specific to how the
addr messages are set up in the test bodies. To allow other callers to also use
`AddrReceiver`, only apply the assertion logic if the caller indicates
desirability by setting `test_addr_contents` to true when initializing the
class.

d6d2ab9845 test: MiniWallet: fix fee calculation for P2PK and check tx vsize (Sebastian Falbesoner)
ce024b1c0e test: MiniWallet: force P2PK signature to have fixed size (71 bytes) (Sebastian Falbesoner)
Pull request description:
This PR is a follow-up to #21945. It aims to both fix the fee calculation for P2PK mode transactions and enable its vsize check. Currently, the latter assumes a fixed tx length, which is fine for anyone-can-spend txs but doesn't apply to P2PK output spends due to varying DER signature size; the vsize check is therefore disabled for P2PK mode on master branch.
Creating one million DER signatures with MiniWallet shows the following distribution of sizes (smart people with better math skills probably could deduce the ratios without trying, but hey):
| DER signature size [bytes] | #occurences (ratio) |
| ------------- | ------------- |
| 71 | 498893 (49.89%) |
| 70 | 497244 (49.72%) |
| 69 | 3837 (0.38%) |
| 68 | 22 (0.0022%) |
Note that even smaller signatures are possible (for smaller R and S values with leading zero bytes), it's just that the probability decreases exponentially. Instead of choosing a large vsize check range and hoping that smaller signatures are never created (potentially leading to flaky tests), the proposed solution is ~~to limit the signature size to the two most common sizes 71 and 70 (>99.6% probability) and then accordingly only check for two vsize values; the value to be used for fee calculation is a decimal right between the two possible sizes (167.5 vbytes) and for the vsize check it's rounded down/up integer values are used.~~ to simply grind the signature to a fixed size of 71 bytes (49.89% probability, i.e. on average each call to `sign_tx()`, on average two ECC signing operations are needed).
~~The idea of grinding signatures to a fixed size (similar to https://github.com/bitcoin/bitcoin/pull/13666 which grinds to low-R values) would be counter-productive, as the signature creation in the test suite is quite expensive and this would significantly slow down tests that calculate hundreds of signatures (like e.g. feature_csv_activation.py).~~

c490e17ef6 doc: Add release notes for the `-rpcwaittimeout` cli parameter (Christian Decker)
a7fcc8eb59 rpc: Add a `-rpcwaittimeout` parameter to limit time spent waiting (Christian Decker)
Pull request description:
Adds a new numeric `-rpcwaittimeout` that can be used to limit the
time we spend waiting on the RPC server to appear. This is used by
downstream projects to provide a bit of slack when `bitcoind`s RPC
interface is not available right away.
This makes the `-rpcwait` argument more useful, since we can now limit
how long we'll ultimately wait, before potentially giving up and reporting
an error to the caller. It was discussed in the context of the BTCPayServer
wanting to have c-lightning wait for the RPC interface to become available
but still have the option of giving up eventually ([4355]).
I checked with laanwj whether this is already possible ([comment]), and
whether this would be a welcome change. Initially I intended to repurpose
the (optional) argument to `-rpcwait`, however I decided against it since it
would potentially break existing configurations, using things like `rpcwait=1`,
or `rpcwait=true` (the former would have an unintended short timeout, when
old behavior was to wait indefinitely).
~Due to its simplicity I didn't implement a test for it yet, but if that's desired I
can provide one.~ Test was added during reviews.

With `banlist.dat` (being written in addrv1 format) if we would try to
write a Tor v3 subnet, it would serialize as a dummy-all-0s IPv6
address and subsequently, when deserialized will not result in the same
subnet.
This problem does not exist with `banlist.json` where the data is saved
in textual, human-readable form.
30aee2dfe6 tests: Add test for compact block HB selection (Pieter Wuille)
6efbcec4de Protect last outbound HB compact block peer (Suhas Daftuar)
Pull request description:
If all our high-bandwidth compact block serving peers (BIP 152) stall block
download, then we can be denied a block for (potentially) a long time. As
inbound connections are much more likely to be adversarial than outbound
connections, mitigate this risk by never removing our last outbound HB peer if
it would be replaced by an inbound.

Pull request description:
This Commit does 3 things:
1) Adds a test case for checking reacceptance a previously rejected block which
was too far in the future.
~~2) clean up uses of rehash or calc_sha256 where it was not needed~~
3) While constructing block 44, this commit makes the code consistent with the expected figure in
the comment just above it by adding a transaction to the block.
4) Fix comment describing `sign_tx()` function

451b96f7d2 test: kill process group to avoid dangling processes (S3RK)
Pull request description:
This is an alternative to #19281
This PR fixes a problem when after test failure with `--failfast` option there could be dangling nodes. The nodes will continue to occupy rpc/p2p ports on the machine and will cause further test failures.
If there are any dangling nodes left at the end of the test run we kill the whole process group.
Pros: the operations is immediate and won't lead to CI timeout
Cons: the test_runner process is also killed and exit code is 137
Example output:
```
...

rpc_deprecated.py | ✓ Passed | 2 s

Pull request description:
Builds on top of #22051, adding signing support after derivation support.
Nothing is changed in descriptor features. Signing works for key path and script path spending, through the normal sending functions, and PSBT-based RPCs. However, PSBT usability is rather low as no extensions have been defined to convey Taproot-specific information, so all script information must be known to the signing wallet.

01eedf3821 test: doc: improve doc for chain_transaction() helper (Sebastian Falbesoner)
6e63e366d6 test: refactor: dedup utility function chain_transaction() (Sebastian Falbesoner)
Pull request description:
Both tests `mempool_packages.py` and `mempool_package_onemore.py` define a utility function `chain_transaction` with a similar implementation. This PR deduplicates it by moving it into the util package and keeping the more general properties:
* pass a list of parent_txids/vouts instead of single values
* always mark the BIP125-replaceable flag for txs, created via `createrawtransaction` (this is needed by the `mempool_package_onemore.py` test, but doesn't hurt the other one)
This is a low-hanging fruit; as a potential follow-up one could probably also deduplicate the function `chain_transaction` in `rpc_packages.py`, which looks a bit different, as it also takes the parent locking script into account and doesn't send the tx.
