Since the previous commit, CTransaction object calls to the
methods `.rehash()` and `.calc_sha256()` are effectively no-ops
if the returned value is not used, so we can just remove them.
Rather than txids (represented by the fields `.sha256` and `.hash`)
being stateful, simply compute them on-the-fly. This ensures that
the correct values are always returned and takes the burden of
rehashing from test writers, making the code shorter overall.
In a first step, the fields are kept at the same name with @property
functions as drop-in replacements, for a minimal diff. In later commits,
the names are changed to be more descriptive and indicating the return
type of the txid.

9f36962b07eff2369577a17c8adeaa0433697e1c policy: uncap datacarrier by default (Greg Sanders)
Pull request description:
Retains the `-datacarrier*` args, marks them as deprecated, and does not require another startup argument for multiple OP_RETURN outputs.
If a user has set `-datacarriersize` the value is "budgeted" across all seen OP_RETURN output scriptPubKeys. In other words the total script bytes stays the same, but can be spread across any number of outputs. This is done to not introduce an additional argument to support multiple outputs.
I do not advise people use the option with custom arguments and it is marked as deprecated to not mislead as a promise to offer it forever. The argument itself can be removed in some future release to clean up the code and minimize footguns for users.

f728b6b11100fae1e27f7a0ef92a5930fa8cffb3 init: Configure reachable networks before we start the RPC server (Matthew Zipkin)
Pull request description:
Closes https://github.com/bitcoin/bitcoin/issues/32433
`MaybeFlipIPv6toCJDNS()` relies on `g_reachable_nets` to distinguish between CJDNS addresses and other IPv6 addresses. In particular, [RFC4193](https://www.rfc-editor.org/rfc/rfc4193#section-3.1) address or "Unique Local Address" with the L-bit unset also begins with the `fc` prefix. #32433 highlights a use case for these addresses that have nothing to do with CJDNS.
On master we don't parse init flags like `-cjdnsreachable` until *after* the HTTP server has started, causing conflicts with `-rpcallowip` because CJDNS doesn't support subnets.
This PR ensures that `NET_CJDNS` is only present in the reachable networks list if set by `-cjdnsreachable` *before* `-rpcallowip` is checked. If it is set all `fc` addresses are assumed to be CJDNS, can not have subnets, and can't be set for `-rpcallowip`.
I also noted this specific parameter interaction in the init help as well as the error message if configured incorrectly.
This can be tested locally:
`bitcoind -regtest -rpcallowip=fc00:dead:beef::/64 -rpcuser=u -rpcpassword=p`
On master this will just throw an error that doesn't even mention IPv6 at all.
On the branch, this will succeed and can be tested by adding the ULA to a local interface.
On linux: `sudo ip -6 addr add fc00:dead:beef::1/64 dev lo`
On macos: `sudo ifconfig lo0 inet6 fc00:dead:beef::1/128 add`
then: `curl -v -g -6 --interface fc00:dead:beef::1 u:p@[::1]:18443 --data '{"method":"getblockcount"}'`
If the `rpcallowip` option is removed, the RPC request will fail to authorize.
Finally, adding `-cjdnsreachable` to the start up command will throw an error and specify the incompatibility:
> RFC4193 is allowed only if -cjdnsreachable=0.

ed179e0a6528c39b3bca76365f256716f917e19b test: apply microsecond precision to test framework logging (Martin Zumsande)
Pull request description:
When analyzing functional test logs (produced with `combine_logs.py`), entries sometimes sort slightly out of order because even though python prints 6 digits for microsecond precision, it fills up the last 3 digits with zeroes. For example, it may look like a message was received by the test framework before it was sent by the node.
Change this to actually use microsecond precision - this should make combined logs a little bit easier to analyze.

cdfb70e5a6a9235ea18dd2cb8148b757902dc08e signet: split decode_psbt miner helper (Sjors Provoost)
Pull request description:
[BIP325](https://github.com/bitcoin/bips/blob/master/bip-0325.mediawiki) mentions the following rule:
> In the special case where an empty solution is valid (ie scriptSig and scriptWitness are both empty) this additional commitment can optionally be left out. This special case is to allow non-signet-aware block generation code to be used to test a custom signet chain where the challenge is trivially true.
Such a signet can be created using e.g. `-signetchallenge=51` (`OP_TRUE`). However `contrib/signet/miner` won't omit the commitment.
This PR improves the miner by skipping the PSBT for known trivial scripts (just `OP_TRUE` and trivial pushes for now). This prevents it from appending the 4 byte signet header to the witness commitment, as allowed by the above rule.
---
Previously the script would fail with `PSBT signing failed`, making it difficult to mine. This is no longer the case.

Instead of failing during initialization and shutting down the app when encountering a legacy wallet, skip loading the wallet and notify the user accordingly.
This allows users to access migration functionalities without needing to manually remove the wallet from settings.json or resort to using the bitcoin-wallet utility.

https://github.com/llvm/llvm-project/blob/main/clang/docs/ReleaseNotes.rst.
Datacarrier output script sizes and output counts are now
uncapped by default.
To avoid introducing another startup argument, we modify the
OP_RETURN accounting to "budget" the spk sizes.
If a user has set a custom default, this results in that
budget being spent over the sum of all OP_RETURN outputs'
scripts in the transaction, no longer capping the number
of OP_RETURN outputs themselves. This should allow a
superset of current behavior while respecting the passed
argument in terms of total arbitrary data storage.

f3a444c45fb4bf4e51d53ebf1cf4c2631ded481c gui: Disallow loading legacy wallets (Ava Chow)
09955172f38a4bbfa6fc8ffba3b057c73e7e3bbe wallet, rpc: Give warning in listwalletdir for legacy wallets (Ava Chow)
Pull request description:
A new field `warnings` is added for each wallet in `listwalletdir`. If a legacy wallet is detected, the warning will contain a message that the wallet is a legacy wallet and will need to be migrated before it can be loaded.
In the GUI, the "Open Wallet" menu is changed to show legacy wallets greyed out with "(needs migration)" appended to their name to indicate to the user that the legacy wallet will need to be migrated.

24e5fd3bedcebacbc10f0449be61be636b77dd79 fs: remove _POSIX_C_SOURCE defining (fanquake)
Pull request description:
On Linux systems, `_POSIX_C_SOURCE` will default to `200809L` (since glibc 2.10). There's currently no reason for us to undefine it, and then set it to an earlier value. Also tested with musl libc.
I think if anything, the project should be settings macros like `_POSIX_C_SOURCE`, globally.

It reuses the logic from the `coins_view` target, except it uses an
in-memory CCoinsViewDB as the backend.
Note `CCoinsViewDB` will assert the best block hash is never null, so we
slightly modify the coins_view fuzz logic to take care of this.

Pull request description:
This PR adds some additional logging to help measure performance of compact block reconstruction.
1. Adds a message to the beginning of `PartiallyDownloadedBlock::InitData()` so that that the logs indicate the amount of time it takes to populate a compact block from mempool transactions.
2. Logs the size of the transactions which a node did not have in its mempool and was forced to request.
3. Logs the size and number of transactions that a node sends to it's peer in a `BLOCKTXN` to fulfill a compact block `GETBLOCKTXN` request.
