7ad414f4bf doc: add comment about CCoinsViewDBCursor constructor (James O'Beirne)
0f8a5a4dd5 move-only(ish): don't expose CCoinsViewDBCursor (James O'Beirne)
615c1adfb0 refactor: wrap CCoinsViewCursor in unique_ptr (James O'Beirne)
Pull request description:
I tripped over this one for a few hours at the beginning of the week, so I've sort of got a personal vendetta against `CCoinsView::Cursor()` returning a raw pointer.
Specifically in the case of CCoinsViewDB, if a raw cursor is allocated and not freed, a cryptic leveldb assertion failure occurs on CCoinsViewDB destruction (`Assertion 'dummy_versions_.next_ == &dummy_versions_' failed.`).
This is a pretty simple change.

29e5dd1a5b consensus refactor: extract ComputeTapleafHash, ComputeTaprootMerkleRoot (Pieter Wuille)
Pull request description:
Includes:
* First commit from #21365, adding TaprootSpendData in SigningProvider
* A refactor to expose ComputeTapleafHash and ComputeTaprootMerkleRoot from script/interpreter
* A tiny change to make `getaddressinfo` report tr() descriptors as solvable (so that inferred descriptors are shown), despite not having signing code for them.
* Logic to infer the script tree back from TaprootSpendData, and then use that to infer descriptors.

Adds an error output parameter to all GetReservedDestination functions
so that callers can get the actual reason that a change address could
not be fetched. This more closely matches GetNewDestination. This allows
for more granular error messages, such as one that indicates that
bech32m addresses cannot be generated yet.
We don't want the legacy wallet to ever have bech32m addresses so don't
allow importing them. This includes addmultisigaddress as that is a
legacy wallet only RPC
Additionally, bech32m multisigs are not available yet, so disallow them
in createmultisig.
If a transaction as a segwit output, use a bech32m change address if
they are available. If not, fallback to bech32. If bech32 change
addresses are unavailable, fallback to the default address type.
Bech32m addresses need their own OutputType
We are not ready to create DescriptorScriptPubKeyMans which produce
bech32m addresses. So don't allow generating them.

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.
Save the banlist in `banlist.json` instead of `banlist.dat`.
This makes it possible to store Tor v3 entries in the banlist on disk
(and any other addresses that cannot be serialized in addrv1 format).
Only read `banlist.dat` if it exists and `banlist.json` does not
exist (first start after an upgrade).
