722e9a418d wallet, rpc: add `label` to `listsinceblock` (brunoerg)
852891ff98 refactor, wallet: use optional for `label` in `ListTransactions` (brunoerg)
Pull request description:
This PR adds `label` parameter to `listsinceblock` to be able to fetch all incoming transactions having the specified label since a specific block.
It's possible to use it in `listtransactions`, however, it's only possible to set the number of transactions to return, not a specific block to fetch from. `getreceivedbylabel` only returns the total amount received, not the txs info. `listreceivedbylabel` doesn't list all the informations about the transactions and it's not possible to fetch since a block.

6fb102c9f3 test: Changed small_txpuzzle_randfee to return the virtual size instead of the transaction hex for feerate calculation. (Randall Naar)
Pull request description:
The fee rates used in feature_fee_estimation.py are calculated using the raw transaction size instead of the virtual transaction size (which is used in 'CBlockPolicyEstimator::processBlockTx' and 'CBlockPolicyEstimator::processBlock'). This leads to inconsistencies as the fee rates used in check_raw_estimates are incorrect and can cause assertions to fail.

dd6e8bd71c build: remove BOOST_CPPFLAGS from libbitcoin_util (fanquake)
82e272a109 refactor: Move src/interfaces/*.cpp files to libbitcoin_common.a (Ryan Ofsky)
Pull request description:
These belong in `libbitcoin_common.a`, not `libbitcoin_util.a`, because they aren't general-purpose utilities, they just contain some common glue code that is used by both the node and the wallet. Another reason not to include these in `libbitcoin_util.a` is to prevent them from being used by the kernel library.
Also rename ambiguous `MakeHandler` functions to `MakeCleanupHandler` and `MakeSignalHandler`. Cleanup function handler was introduced after boost signals handler, so original naming didn't make much sense.
This just contains a move-only commit, and a rename commit. There are no actual code or behavior changes.
This PR is an alternative to #26293, and solves the same issue of removing a boost dependency from the _util_ library. The advantages of this PR compared to #26293 are that it keeps the source directory structure more flat, and it avoids having to change #includes all over the codebase.

3198e4239e test: check that loading descriptor wallet with legacy entries throws error (Sebastian Falbesoner)
349ed2a0ee wallet: throw error if legacy entries are present on loading descriptor wallets (Sebastian Falbesoner)
Pull request description:
Loading a descriptor wallet currently leads to a segfault if a legacy key type entry is present that can be deserialized successfully and needs SPKman-interaction. To reproduce with a "cscript" entry (see second commit for details):
```
$ ./src/bitcoin-cli createwallet crashme

Segmentation fault (core dumped)
```
Background: In the wallet key-value-loading routine, most legacy type entries require a `LegacyScriptPubKeyMan` instance after successful deserialization. On a descriptor wallet, creating that (via method `GetOrCreateLegacyScriptPubKeyMan`) fails and then leads to a null-pointer dereference crash. E.g. for CSCRIPT: 50422b770a/src/wallet/walletdb.cpp (L589-L594)
~~This PR fixes this by simply ignoring legacy entries if the wallet flags indicate that we have a descriptor wallet. The second commits adds a regression test to the descriptor wallet's functional test (fortunately Python includes sqlite3 support in the standard library).~~
~~Probably it would be even better to throw a warning to the user if unexpected legacy entries are found in descriptor wallets, but I think as a first mitigation everything is obvisouly better than crashing. As far as I'm aware, descriptor wallets created/migrated by Bitcoin Core should never end up in a state containing legacy type entries though.~~
This PR fixes this by throwing an error if legacy entries are found in descriptor wallets on loading.

f930aefff9 wallet: bugfix, 'CoinsResult::Erase' is erasing only one output of the set (furszy)
Pull request description:
This comes with #26559.
Solving few bugs inside the wallet's transaction creation
process and adding test coverage for them.
Plus, making use of the `CoinsResult::total_amount` cached value
inside the Coin Selection process to return early if we don't have
enough funds to cover the target amount.
### Bugs
1) The `CoinsResult::Erase` method removes only one
output from the available coins vector (there is a [loop break](c1061be14a/src/wallet/spend.cpp (L112))
that should have never been there) and not all the preset inputs.
Which on master is not a problem, because since [#25685](https://github.com/bitcoin/bitcoin/pull/25685)
we are no longer using the method. But, it's a bug on v24
(check [#26559](https://github.com/bitcoin/bitcoin/pull/26559)).
This method it's being fixed and not removed because I'm later using it to solve
another bug inside this PR.
2) As we update the total cached amount of the `CoinsResult` object inside
`AvailableCoins` and we don't use such function inside the coin selection
tests (we manually load up the `CoinsResult` object), there is a discrepancy
between the outputs that we add/erase and the total amount cached value.
### Improvements
* This makes use of the `CoinsResult` total amount field to early return
with an "Insufficient funds" error inside Coin Selection if the tx target
amount is greater than the sum of all the wallet available coins plus the
preset inputs amounts (we don't need to perform the entire coin selection
process if we already know that there aren't enough funds inside our wallet).
### Test Coverage
1) Adds test coverage for the duplicated preset input selection bug that we have in v24.
Where the wallet invalidly selects the preset inputs twice during the Coin Selection
process. Which ends up with a "good" Coin Selection result that does not cover the
total tx target amount. Which, alone, crashes the wallet due an insane fee.
But.. to make it worst, adding the subtract fee from output functionality
to this mix ends up with the wallet by-passing the "insane" fee assertion,
decreasing the output amount to fulfill the insane fee, and.. sadly,
broadcasting the tx to the network.
2) Adds test coverage for the `CoinsResult::Erase` method.

0b78110f73 test: Move tx creation to create_self_transfer_multi (kouloumos)
Pull request description:
Two birds with one stone: replacement of https://github.com/bitcoin/bitcoin/pull/26278 with simplification of the MiniWallet's transaction creation logic.
Currently the MiniWallet creates simple txns (1 input, 1 output) with `create_self_transfer`. https://github.com/bitcoin/bitcoin/pull/24637 introduced `create_self_transfer_multi` **which uses** `create_self_transfer` to create a "transaction template" which then adjusts (copy and mutate inputs and outputs) in order to create more complex multi-input multi-output transactions.
This can more easily lead to issues such as https://github.com/bitcoin/bitcoin/pull/26278 and is more of a maintenance burden.
This PR simplifies the logic by going the other way around. Now `create_self_transfer` **uses** `create_self_transfer_multi`.
The transaction creation logic has been moved to `create_self_transfer_multi` which is being called by `create_self_transfer` to construct the simple case of 1 input 1 output transaction.

Pull request description:

This is an anti-fingerprinting measure. See `BlockRequestAllowed` in `net_processing`.
It's been in Bitcoin Core since 2014, introduced in #2910 and later improved to not rely on checkpoints.
Older and alternative clients might still serve these blocks, so not throwing an error.
Allowing whitelisted nodes to fetch these blocks anyway might be nice.

The CoinsResult class will now count the raw total amount and the effective
total amount internally (inside the 'CoinsResult::Add' and 'CoinsResult::Erase'
methods).
So there is no discrepancy between what we add/erase and the total values.
(which is what was happening on the coinselector_test because the 'CoinsResult'
object is manually created there, and we were not keeping the total amount
in sync with the outputs being added/removed).
Aside from the cleanup, this solves a bug in the following-up commit. Because, in these
tests, we are manually adding/erasing outputs from the CoinsResult object but never
updating the internal total amount field.
This exercises the bug inside CoinsResult::Erase that
ends up on (1) a wallet crash or (2) a created and
broadcasted tx that contains a reduced recipient's amount.
This is covered by making the wallet selects the preset
inputs twice during the coin selection process.
Making the wallet think that the selection process result covers
the entire tx target when it does not. It's actually creating
a tx that sends more coins than what inputs are covering for.
Which, combined with the SFFO option, makes the wallet
incorrectly reduce the recipient's amount by the difference
between the original target and the wrongly counted inputs.
Which means, a created and relayed tx sending less coins to
the destination than what the user inputted.

Prior to #21160, `TxRelay::m_tx_inventory_to_send` was guaranteed to be empty on the first `SendMessages` call, as transaction announcements were only queued for fully connected peers. #21160 replaced a `CConnman::ForEachNode` call with a loop over `PeerManagerImpl::m_peer_map`, in which the txid for a transaction to be relayed is added to `TxRelay::m_tx_inventory_to_send` for all peers. Even for those peers that have not completed the version handshake. Prior to the PR this was not the case as `ForEachNode` has a "fully connected check" before calling a function for each node.

As mentioned in #26571, the task running the USDT interface tests fail when run in docker. cc7335edc8 in #25528 added that the tests are run in a **VM** in Cirrus CI. Running them locally in docker containers might not work:
- We use [bcc] as tracing toolkit which requires the kernel headers to compile the BPF bytecode. As docker containers use the hosts kernel and don't run their own, there is a potential for mismatches between kernel headers available in the container and the host kernel. This results in a failure loading the BPF byte code.
- Privilges are required to load the BPF byte code into the kernel. Normally, the docker containers aren't run with these.
- We currently use an untrusted third-party PPA to install the bpfcc-tools package on Ubuntu 22.04. Using this on a local dev system could be a security risk.
To not hinder the ASan + LSan + UBSan part of the CI task, the USDT tests are disabled on non-CirrusCI runs.

fa15c671f7 test: Remove unused blocktools imports from wallet_bumpfee (MarcoFalke)
Pull request description:
Seems bloaty and confusing to use "tools" when a single RPC can already achieve the same.

dbed28968a test: refactor: eliminate genesis block timestamp magic numbers (Sebastian Falbesoner)
Pull request description:
This tiny PR replaces all occurences of the regtest/testnet genesis block timestamp (found via `git grep 1296688602`) with the constant `TIME_GENESIS_BLOCK` to increase the readability.

150340aeac test: remove unneeded extra_args code (josibake)
989a52e0a5 test: add extra_args to BTF class (josibake)
Pull request description:
## problem
If you try to add `extra_args` when using `TestShell`, you will get the following error:
```python
>>> import sys
>>>
>>> sys.path.insert(0, "/home/josibake/bitcoin/test/functional")
>>>
>>> from test_framework.test_shell import TestShell
>>> test = TestShell().setup(num_nodes=2, extra_args=[[],['-fallbackfee=0.0002']])
Traceback (most recent call last):
File "<stdin>", line 1, in <module>
File "/home/josibake/bitcoin/test/functional/test_framework/test_shell.py", line 41, in setup
raise KeyError(key + " not a valid parameter key!")
KeyError: 'extra_args not a valid parameter key!'
>>>
```
## solution
add `self.extra_args = None` so that `extra_args` is recognized as a valid parameter to be passed to `BitcoinTestFramework`
```python
>>> import sys
>>>
>>> sys.path.insert(0, "/home/josibake/bitcoin/test/functional")
>>>
>>> from test_framework.test_shell import TestShell
>>> test = TestShell().setup(num_nodes=2, extra_args=[[],['-fallbackfee=0.0002']])
