Pull request description:
This PR includes changes split from https://github.com/bitcoin/bitcoin/pull/30454. They improve the functional test framework, allowing users to [run individual functional tests](https://github.com/hebasto/bitcoin/issues/146) from the build directory in the new CMake-based build system.
This functionality is not available for out-of-source builds using the current Autotools-based build system, which always requires write permissions for the source directory. Nevertheless, this PR can be tested as suggested in https://github.com/bitcoin/bitcoin/pull/30463#issuecomment-2232618421:
1. Make an out-of-source build:
```
$ ./autogen.sh
$ mkdir ../build && cd ../build
$ ../bitcoin/configure
$ make
```
2. Create a symlink in the build directory to a functional test:
```
$ ln --symbolic ../../../bitcoin/test/functional/wallet_disable.py ./test/functional/
```
3. Run this symlink:
```
$ ./test/functional/wallet_disable.py
```
The last command fails on the master branch:
```

Pull request description:
This PR taken over from #29264
The PR added an option `max_tx_weight` to transaction funding RPC's that ensures the resulting transaction weight does not exceed the specified `max_tx_weight` limit.
If `max_tx_weight` is not given `MAX_STANDARD_TX_WEIGHT` is used as the max threshold.
This PR addressed outstanding review comments in #29264

In CMake-based build system (1) `config.ini` is created in the build
directory, and (2) `cache` must also be created in the same directory.
This change enables running individual functional tests from the build
directory.

Pull request description:
Add tests for the following v2 handshake scenarios:
1. Disconnection happens when > `MAX_GARBAGE_LEN` bytes garbage is sent
2. Disconnection happens when incorrect garbage terminator is sent
3. Disconnection happens when garbage bytes are tampered with
4. Disconnection happens when AAD of first encrypted packet after the garbage terminator is not filled
5. bitcoind ignores non-empty version packet and no disconnection happens
All these tests require a modified v2 P2P class (different from `EncryptedP2PState` used in `v2_p2p.py`) to implement our custom handshake behaviour based on different scenarios and have been kept in a single test file (`test/functional/p2p_v2_misbehaving.py`). Shifted the test in `test/functional/p2p_v2_earlykeyresponse.py` which is of the same pattern to this file too.

In the Tor case, this prevents us from telling the Tor daemon to send
our incoming connections from the Tor network to an address where we
do not listen (we tried to listen but failed probably because another
application is already listening).
In the other cases (IPv4/IPv6 binds) this also prevents unpleasant
surprises caused by continuing operations even on bind failure. For
example, another application may be listening on portX, bitcoind tries
to bind on portX and portY, only succeeds with portY and continues
operation leaving the user thinking that his bitcoind is listening on
portX whereas another application is listening (the error message in
the log could easily be missed).
Avoid having the functional testing framework start multiple `bitcoind`s
that try to listen on the same `127.0.0.1:18445` (Tor listen for
regtest) if `bind_to_localhost_only` is set to `False`.
Also fix a typo in `test-shell.md` related to `bind_to_localhost_only`.
Fixes https://github.com/bitcoin/bitcoin/issues/22727
This allows a transaction's weight to be bound under a certain
weight if possible and desired. This can be beneficial for future
RBF attempts, or whenever a more restricted spend topology is
desired.

Pull request description:
While reviewing #28307, I noticed that the test framework's `key_to_multisig_script` helper (introduced in #23305) is broken for pubkey count (n) and threshold (k) values larger than 16. This is due to the implementation currently enforcing a direct single-byte data push (using `CScriptOp.encode_op_n`), which obviously fails for values 17+. Fix that by passing the numbers directly to the CScript list, where it's automatically converted to minimally-encoded pushes (see class method `CScript.__coerce_instance`, branch `isinstance(other, int)`).
The second commit adds a unit test to ensure that the encoding is correct.

429ec1aaaaafab150f11e27fcf132a99b57c4fc7 refactor: Rename CTransaction::nVersion to version (Ava Chow)
27e70f1f5be1f536f2314cd2ea42b4f80d927fbd consensus: Store transaction nVersion as uint32_t (Ava Chow)
Pull request description:
Given that the use of a transaction's nVersion is always as an unsigned int, it doesn't make sense to store it as signed and then cast it to unsigned everywhere it is used and displayed.
Since a few alternative implementations have recently been revealed to have made an error with this signedness that would have resulted in consensus failure, I think it makes sense for us to just make this always unsigned to make it clear that the version is treated as unsigned. This would also help us avoid future potential issues with signedness of this value.
I believe that this is safe and does not actually change what transactions would or would not be considered both standard and consensus valid. Within consensus, the only use of the version in consensus is in BIP68 validation which was already casting it to uint32_t. Within policy, although it is used as a signed int for the transaction version number check, I do not think that this change would change standardness. Standard transactions are limited to the range [1, 2]. Negative numbers would have fallen under the < 1 condition, but by making it unsigned, they are still non-standard under the > 2 condition.
Unsigned and signed ints are serialized and unserialized the same way so there is no change in serialization.

0000276b31cea5e443a59d94a98c569293ada951 test: Remove redundant verack check (MarcoFalke)
Pull request description:
Currently the sync in `connect_nodes` mentions the `version` and `verack` message types, but only checks the `verack`. Neither check is required, as the `pong` check implies both. In case of failure, the debug log will have to be consulted anyway, so the redundant check doesn't add value.
Also clarify in the comments that the goal is to check the flag `fSuccessfullyConnected` indirectly.

c17550bc3a68faa1eb82d1bdb767b41d8cd85a6b test: MiniWallet: fix tx padding (`target_weight`) for large sizes, improve accuracy (Sebastian Falbesoner)
Pull request description:
MiniWallet allows to create padded transactions that are equal or slightly above a certain `target_weight` (first introduced in PR #25379, commit 1d6b438ef0ccd05e1522ac38b44f847c1d93e72f), which can be useful especially for mempool-related tests, e.g. for policy limit checks or scenarios to trigger mempool eviction. Currently the `target_weight` parameter doesn't play together with `fee_rate` though, as the fee calculation is incorrectly based on the tx vsize before the padding output is added, so the fee-rate is consequently far off. This means users are forced to pass an absolute fee, which can be quite inconvenient and leads to lots of duplicated "calculate absolute fee from fee-rate and vsize" code with the pattern `fee = (feerate / 1000) * (weight // 4)` on the call-sites.
This PR first improves the tx padding itself to be more accurate, adds a functional test for it, and fixes the `fee_rate` treatment for the `{create,send}_self_transfer` methods. (Next step would be to enable this also for the `_self_transfer_multi` methods, but those currently don't even offer a `fee_rate` parameter). Finally, the ability to pass both `target_weight` and `fee_rate` is used in the `mempool_limit.py` functional test. There might be more use-cases in other tests, that could be done in a follow-up.

Pull request description:
When restarting `bitcoind` during an ongoing reindex without setting the `-reindex` flag again, the block and coins db is left intact, but any data from the optional indexes is discarded. While not a bug per se, wiping the data again is
wasteful, both in terms of having to write it again, as well as potentially leading to longer startup times. So keep the index data instead when continuing a prior reindex.
Also includes a bugfix and smaller code cleanups around the reindexing code. The bug was introduced in b47bd959207e82555f07e028cc2246943d32d4c3: "kernel: De-globalize fReindex".

Pull request description:
`struct.pack` has many issues:
* The format string consists of characters that may be confusing and may need to be looked up in the documentation, as opposed to using easy to understand self-documenting code.
This lead to many test bugs, which weren't hit, which is fine, but still confusing. Ref: https://github.com/bitcoin/bitcoin/pull/29400, https://github.com/bitcoin/bitcoin/pull/29399, https://github.com/bitcoin/bitcoin/pull/29363, fa3886b7c69cbbe564478f30bb2c35e9e6b1cffa, ...
Fix all issues by using the built-in `int` helpers `to_bytes` via a scripted diff.
Review notes:
* For `struct.pack` and `int.to_bytes` the error behavior is the same, although the error messages are not identical.
* Two `struct.pack` remain. One for float serialization in a C++ code comment, and one for native serialization.

The helper assumes that the n and k values have to be provided as a
single byte push operation, which is only possible for values up to 16.
Fix that by passing the numbers directly to the CScript list, where it's
automatically converted to minimally-encoded pushes (see class
method `CScript.__coerce_instance`, branch `isinstance(other, int)`).
In case of 17..20, this means that the data-pushes are done with two
bytes using OP_PUSH1 (0x01), e.g. for n=20: 0x01,0x14

Pull request description:
Fixing https://github.com/bitcoin/bitcoin/issues/28250#issuecomment-1674830104 and more.
Currently, redeem scripts longer than 520 bytes, which are technically valid under segwit rules, have flaws in the following processes:
1) The multisig creation process fails to deduce the output descriptor, resulting in the generation of an incorrect descriptor. Additionally, the accompanying user warning is also inaccurate.
2) The `signrawtransactionwithkey` RPC command fail to sign them.
3) The legacy wallet `addmultisigaddress` wrongly discards them.
The issue arises because most of these flows are utilizing the legacy spkm keystore, which imposes
the [p2sh max redeem script size rule](ded6873340/src/script/signingprovider.cpp (L160)) on all scripts. Which blocks segwit redeem scripts longer than
the max element size in all the previously mentioned processes (`createmultisig`, `addmultisigaddress`, and
`signrawtransactionwithkey`).
This PR fixes the problem, enabling the creation of multisig output descriptors involving more than 15 keys and
allowing the signing of these scripts, along with other post-segwit redeem scripts that surpass the 520-byte
p2sh limit.
Important note:
Instead of adding support for these longer redeem scripts in the legacy wallet, an "unsupported operation"
error has been added. The reasons behind this decision are:
1) The introduction of this feature brings about a compatibility-breaking change that requires downgrade
protection; older wallets would be unable to interact with these "new" legacy wallets.
2) Considering the ongoing deprecation of the legacy spkm, this issue provides another compelling
reason to transition towards descriptors.
Testing notes:
To easily verify each of the fixes, I decoupled the tests into standalone commits. So they can be
cherry-picked on top of master. Where `rpc_createmultisig.py` (with and without the `--legacy-wallet`
arg) will fail without the bugs fixes commits.
Extra note:
The initial commits improves the `rpc_createmultisig.py` test in many ways. I found this test very
antiquated, screaming for an update and cleanup.

Currently, transport version is a global variable declared as
TRANSPORT_VERSION in v2_p2p.py. Making it an instance variable
would help in sending non empty transport version packets for
testing purposes. It might also help EncryptedP2PState be more
extensible in far future protocol upgrades.
6629d1d0f8285d1bf2d87341a856abe903f26c13 test: improve robustness of connect_nodes() (furszy)
Pull request description:
Decoupled from #27837 because this can help other too, found it investigating a CI failure https://cirrus-ci.com/task/5805115213348864?logs=ci#L3200.
The `connect_nodes` function in the test framework relies on a stable number of peer
connections to verify that the new connection between the nodes is successfully established.
This approach is fragile, as any of the peers involved in the process can drop, lose, or
create a connection at any step, causing subsequent `wait_until` checks to stall indefinitely
even when the peers in question were connected successfully.
This commit improves the situation by using the nodes' subversion and the connection
direction (inbound/outbound) to identify the exact peer connection and perform the
checks exclusively on it.

Pull request description:
Split from #26596
This PR adds `BerkeleyRODatabase` which is an independent implementation of a BDB file parser. It provides read only access to a BDB file, and can therefore be used as a read only database backend for wallets. This will be used for dumping legacy wallet records and migrating legacy wallets without the need for BDB itself.
Wallettool's `dump` command is changed to use `BerkeleyRODatabase` instead of `BerkeleyDatabase` (and `CWallet` itself) to demonstrate that this parser works and to test it against the existing wallettool functional tests.

[BIP341](https://github.com/bitcoin/bips/blob/master/bip-0341.mediawiki#constructing-and-spending-taproot-outputs) defines a NUMS point `H` as *H = lift_x(0x50929b74c1a04954b78b4b6035e97a5e078a5a0f28ec96d547bfee9ace803ac0)* which is [constructed](11af7015de/src/modules/rangeproof/main_impl.h (L16)) by taking the hash of the standard uncompressed encoding of the [secp256k1](https://www.secg.org/sec2-v2.pdf) base point G as X coordinate."
Add this as a constant so it can be used in our codebase. My primary motivation is BIP352 specifies a special case for when taproot spends use `H` as the internal key, but outside of BIP352 it seems generally useful to have `H` in the codebase, for testing or other use cases.

Pull request description:
Closes https://github.com/bitcoin/bitcoin/issues/2960
Bitcoin Core's JSONRPC server behaves with a special blend of 1.0, 1.1 and 2.0 behaviors. This introduces compliance issues with more strict clients. There are the major misbehaviors that I found:
- returning non-200 HTTP codes for RPC errors like "Method not found" (this is not a server error or an HTTP error)
- returning both `"error"` and `"result"` fields together in a response object.
- different error-handling behavior for single and batched RPC requests (batches contain errors in the response but single requests will actually throw HTTP errors)
https://github.com/bitcoin/bitcoin/pull/15495 added regression tests after a discussion in https://github.com/bitcoin/bitcoin/pull/15381 to kinda lock in our RPC behavior to preserve backwards compatibility.
https://github.com/bitcoin/bitcoin/pull/12435 was an attempt to allow strict 2.0 compliance behind a flag, but was abandoned.
The approach in this PR is not strict and preserves backwards compatibility in a familiar bitcoin-y way: all old behavior is preserved, but new rules are applied to clients that opt in. One of the rules in the [JSON RPC 2.0 spec](https://www.jsonrpc.org/specification#request_object) is that the kv pair `"jsonrpc": "2.0"` must be present in the request. Well, let's just use that to trigger strict 2.0 behavior! When that kv pair is included in a request object, the [response will adhere to strict JSON-RPC 2.0 rules](https://www.jsonrpc.org/specification#response_object), essentially:
- always return HTTP 200 "OK" unless there really is a server error or malformed request
- either return `"error"` OR `"result"` but never both
- same behavior for single and batch requests
If this is merged next steps can be:
- Refactor bitcoin-cli to always use strict 2.0
- Refactor the python test framework to always use strict 2.0 for everything
- Begin deprecation process for 1.0/1.1 behavior (?)
If we can one day remove the old 1.0/1.1 behavior we can clean up the rpc code quite a bit.

For JSON-RPC 2.0 requests we need to distinguish between
a missing "id" field and "id":null. This is accomplished
by making the JSONRPCRequest id property a
std::optional<UniValue> with a default value of
UniValue::VNULL.
A side-effect of this change for non-2.0 requests is that request which do not
specify an "id" field will no longer return "id": null in the response.

3e9c736a26724ffe3b70b387995fbf48c06300e2 test: fix accurate multisig sigop count (BIP16), add unit test (Sebastian Falbesoner)
Pull request description:
In the course of reviewing #29589 I noticed the following buggy call-site of `CScriptOp.decode_op_n` in the CScript's `GetSigOpCount` method:
4cc99df44a/test/functional/test_framework/script.py (L591-L593)
This should be `lastOpcode` rather than `opcode`. The latter is either OP_CHECKMULTISIG or OP_CHECKMULTISIGVERIFY at this point, so `decode_op_n` would result in an error. Also, in `CScript.raw_iter`, we have to return the op as `CScriptOp` type instead of a bare integer, otherwise we can't call the decode method on it. To prevent this in the future, add some simple unit tests for `GetSigOpCount`.
Note that this was unnoticed, as the code part was never hit so far in the test framework.

c4f857cc301d856f3c60acbe6271d3fe19441c7a test: Extends wait_for_getheaders so a specific block hash can be checked (Sergi Delgado Segura)
Pull request description:
Fixes https://github.com/bitcoin/bitcoin/issues/18614
Previously, `wait_for_getheaders` would check whether a node had received **any** getheaders message. This implied that, if a test needed to check for a specific block hash within a headers message, it had to make sure that it was checking the desired message. This normally involved having to manually clear `last_message`. This method, apart from being too verbose, was error-prone, given an undesired `getheaders` would make tests pass.
This adds the ability to check for a specific block_hash within the last `getheaders` message.
