19273d0705 fuzz: set mempool options in wallet_fees (brunoerg)

Pull request description:

  Some functions in `wallet/fees.cpp` (fuzzed by the wallet_fees target) depends on some mempool stuff - e.g. relay current min fee, smart fee and max blocks estimation, relay dust fee and other ones. For better fuzzing of it, it would be great to have these values/interactions. That said, this PR enhances the `wallet_fees` target by:

  - Setting mempool options - `min_relay_feerate`,  `dust_relay_feerate` and `incremental_relay_feerate` - when creating the `CTxMemPool`.
  - Creates a `ConsumeMempoolMinFee` function which is used to have a mempool min fee (similar approach from `MockMempoolMinFee` from unit test).
  - Mock `CBlockPolicyEstimator` - estimateSmartFee/HighestTagretTracket functions, especifically. It's better to mock it then trying to interact to CBlockPolicyEstimator in order to have some effective values due to performance.

  Note that I created `FeeEstimatorTestingSetup` because we cannot set `m_node.fee_estimator` in `ChainTestingSetup` since fae8c73d9e.

be776a1443 wallet: Remove isminetype
Since the only remaining isminetypes are ISMINE_NO and ISMINE_SPENDABLE,
this enum is now just a bool and can be removed. IsMine is changed to
return a bool and any usage of isminetypes and isminefilters are changed
to be the remaining ISMINE_SPENDABLE case.

6a7aa01574 wallet: Remove COutput::spendable and AvailableCoinsListUnspent
In descriptor wallets, we consider all outputs to be spendable as we no
longer have mixed mine and watchonly in a wallet. As such,
COutput::spendable is meaningless and can be removed.

Furthermore, CoinFilterParams::only_spendable can be removed as that was
essentially checking for COutput::spendable.

Lastly, AvailableCoinsListUnspent can also be removed as the wrapper is
now only setting the feerate to std::nullopt which is trivial enough that
a dedicated wrapper is not needed.

daca51bf80 Merge bitcoin/bitcoin#32750: refactor: CFeeRate encapsulates FeeFrac internally
d3b8a54a81 Refactor CFeeRate to use FeeFrac internally (Pol Espinasa)

Pull request description:

  The `FeeFrac` type represents a fraction, intended to be used for `sats/vbyte` or `sats/WU`. It was added to improve accuracy when evaluating fee rates in cluster mempool. [1]
  But it can also be used to fix the precision issues that the current `CFeeRate` class has now.

  At the moment, `CFeeRate` handles the fee rate as  satoshis per kilovirtualbyte: `CAmount / kvB` using an integer.
  This PR fix `CFeeRate` precision issues by encapsulating `FeeFrac` internally keeping backwards compatibility.

  This PR can also be used as a based to use multiple units on RPC calls as detailed in this issue [2].

8bb34f07df Explicitly close all AutoFiles that have been written
There is no way to report a close error from `AutoFile` destructor.
Such an error could be serious if the file has been written to because
it may mean the file is now corrupted (same as if write fails).

So, change all users of `AutoFile` that use it to write data to
explicitly close the file and handle a possible error.

785e1407b0 wallet: Use util::Error throughout AddWalletDescriptor (Ava Chow)

Pull request description:

  #32023 changed `AddWalletDescriptor` to return `util::Error`, but did not change all of the failure cases to do so. This may result in some callers continuing when there was actually an error. Unify all of the failure cases to use `util::Error` so that all callers handle `AddWalletDescriptor` errors in the same way.

  The encapsulated return type is changed from `ScriptPubKeyMan*` to `std::reference_wrapper<DescriptorScriptPubKeyMan>`. This avoids having a value that can be interpreted as a bool, and also removes the need to constantly dynamic_cast the returned value. The only kind of `ScriptPubKeyMan` that can come out of `AddWalletDescriptor` is a `DescriptorScriptPubKeyMan` anyways.

Pull request description:

  Currently, we do not add the sighash field to PSBTs at all, even when we have signed with a non-default sighash. This PR changes the behavior such that when we (attempt to) sign with a sighash other than DEFAULT or ALL, the sighash type field will be added to the PSBT to inform the later signers that a different sighash type was used by a signer. Notably, this is necessary for MuSig2 support as all signers must sign using the same sighash type, but the sighash is not provided in partial signatures.

  Furthermore, because the sighash type can also be provided on the command line, we require that if both a command line sighash type and the sighash field is present, they must specify the same sighash type. However, this was being checked by the wallet, rather than the signing code, so the `descriptorprocesspsbt` RPC was not enforcing this restriction at all, and in fact ignored the sighash field entirely. This PR refactors the checking code so that the underlying PSBT signing function `SignPSBTInput` does the check.

d6001dcd4a wallet: change FillPSBT to take sighash as optional
Instead of having the caller have to figure out the correct sane default
to provide to FillPSBT, have FillPSBT do that by having it take the
sighash type as an optional. This further allows it to distinguish
between an explicit sighash type being provided and expecting the
default value to be used.

Pull request description:

  This PR contains various cleanups around the wallet's master key encryption logic. The default/minimum key derivation rounds magic number of 25000 is hoisted into a constant (member of `CMasterKey`) and two new functions `EncryptMasterKey`/`DecryptMasterKey` are introduced in order to deduplicate code for the derivation round determination and master key en/decryption. Also, mentions of the never-implemented derivation method `scrypt` are removed from the wallet crypter header and both plain and encrypted master key instances are renamed to adapt to moderning coding style (hopefully improving readability).

bd158ab4e3 Merge bitcoin/bitcoin#32023: wallet: removed duplicate call to GetDescriptorScriptPubKeyMan
55b931934a removed duplicate calling of GetDescriptorScriptPubKeyMan (Saikiran)

Pull request description:

  Removed duplicate call to GetDescriptorScriptPubKeyMan and
  Instead of checking linearly I have used find method so time complexity reduced significantly for GetDescriptorScriptPubKeyMan
  after this fix improved performance of importdescriptor part refs https://github.com/bitcoin/bitcoin/issues/32013.

  **Steps to reproduce in testnet environment**

  **Input size:** 2 million address in the wallet

  **Step1:** call importaddresdescriptor rpc method
  observe the time it has taken.

  **With the provided fix:**
  Do the same steps again
  observe the time it has taken.

  There is a huge improvement in the performance. (previously it may take 5 to 6 seconds now it will take 1 seconds or less)

  main changes i've made during this pr:

  1. remove duplicate call to GetDescriptorScriptPubKeyMan method
  2. And inside GetDescriptorScriptPubKeyMan method previously we checking **each address linearly** so each time it is calling HasWallet method which has aquired lock.
  3. Now i've modified this logic call **find method on the map (O(logn)**) time it is taking, so only once we calling HasWallet method.

  **Note:** Smaller inputs in the wallet you may not see the issue but huge wallet size it will definitely impact the performance.

Pull request description:

  `Span` has some issues:

  * It does not support fixed-size spans, which are available through `std::span`.
  * It is confusing to have it available and in use at the same time with `std::span`.
  * It does not obey the standard library iterator build hardening flags. See https://github.com/bitcoin/bitcoin/issues/31272 for a discussion. For example, this allows to catch issues like the one fixed in commit fabeca3458.

  Both types are type-safe and can even implicitly convert into each other in most contexts.

  However, exclusively using `std::span` seems less confusing, so do it here with a scripted-diff.

01960c53c7 fuzz: make FuzzedDataProvider usage deterministic (Martin Leitner-Ankerl)

Pull request description:

  There exist many usages of `fuzzed_data_provider` where it is evaluated directly in the function call.
  Unfortunately, [the order of evaluation of function arguments is unspecified](https://en.cppreference.com/w/cpp/language/eval_order), and a simple example shows that it can differ e.g. between clang++ and g++: https://godbolt.org/z/jooMezWWY

  When the evaluation order is not consistent, the same fuzzing/random input will produce different output, which is bad for coverage/reproducibility. This PR fixes all these cases I have found where unspecified evaluation order could be a problem.

  Finding these has been manual work; I grepped the sourcecode for these patterns, and looked at each usage individually. So there is a chance I missed some.

  * `fuzzed_data_provider`
  * `.Consume`
  * `>Consume`
  * `.rand`

  I first discovered this in https://github.com/bitcoin/bitcoin/pull/29013#discussion_r1420236394. Note that there is a possibility that due to this fix the evaluation order is now different in many cases than when the fuzzing corpus has been created. If that is the case, the fuzzing corpus will have worse coverage than before.

  Update: In list-initialization the order of evaluation is well defined, so e.g. usages in `initializer_list` or constructors that use `{...}` is ok.

Pull request description:

  It is convenient to have a descriptor which specifies both receiving and change addresses in a single string. However, as discussed in https://github.com/bitcoin/bitcoin/issues/17190#issuecomment-895515768, it is not feasible to use a generic multipath specification like BIP 88 due to combinatorial blow up and that it would result in unexpected descriptors.

  To resolve that problem, this PR proposes a targeted solution which allows only a single pair of 2 derivation indexes to be inserted in the place of a single derivation index. So instead of two descriptor `wpkh(xpub.../0/0/*)` and `wpkh(xpub.../0/1/*)` to represent receive and change addresses, this could be written as `wpkh(xpub.../0/<0;1>/*)`. The multipath specifier is of the form `<NUM;NUM>`. Each `NUM` can have its own hardened specifier, e.g. `<0;1h>` is valid. The multipath specifier can also only appear in one path index in the derivation path.

  This results in the parser returning two descriptors. The first descriptor uses the first `NUM` in all pairs present, and the second uses the second `NUM`. In our implementation, if a multipath descriptor is not provided, a pair is still returned, but the second element is just `nullptr`.

  The wallet will not output the multipath descriptors (yet). Furthermore, when a multipath descriptor is imported, it is expanded to the two descriptors and each imported on its own, with the second descriptor being implicitly for internal (change) addresses. There is no change to how the wallet stores or outputs descriptors (yet).

  Note that the path specifier is different from what was proposed. It uses angle brackets and the semicolon because these are unused characters available in the character set and I wanted to avoid conflicts with characters already in use in descriptors.

  Closes #17190

401cc4ec70 fuzz: improve scriptpubkeyman target (brunoerg)

Pull request description:

  Fixes #30541

  This PR aims to improve `scriptpubkeyman` target to avoid timeouts. The input provided in #30541 takes too much time to run because it basically calls only `MarkUnusedAddresses` (300 times * number of spks). The following changes were made to improve it:

  - Reduce keypool size.
  - When calling `MarkUnusedAddresses`, do it with one of the spks per iteration.
  - Remove the specific `AddDescriptorKey` call since it is already covered with `AddWalletDescriptor`.
  - Limit number of iterations to a reasonable value.

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
