416ceb8661117235c76f2985512473ebbc64956b descriptor: check if `rawtr` has only one key. (w0xlt)
Pull request description:
If I understand `rawtr` descriptor correctly, it should only allow `rawtr(KEY)`, not `rawtr(KEY1, KEY2, ...)` or other concatenations.
On master branch, `rawtr(KEY1, KEY2, ...)` will produce the `rawtr(KEY1)` descriptor ignoring the `KEY2, ...` with no error messages or warnings.
For example, the code below will print `rawtr(tprv8ZgxMBicQKsPefef2Doobbq3xTCaVTHcDn6me82KSXY1vY9AJAWD5u7SDM4XGLfc4EoXRMFrJKpp6HNmQWA3FTMRQeEmMJYJ9RPqe9ne2hU/*)#lx9qryfh`
for the supposedly invalid descriptor
`rawtr(tprv8ZgxMBicQKsPefef2Doobbq3xTCaVTHcDn6me82KSXY1vY9AJAWD5u7SDM4XGLfc4EoXRMFrJKpp6HNmQWA3FTMRQeEmMJYJ9RPqe9ne2hU/*, tprv8ZgxMBicQKsPezQ2KGArMRovTEbCGxaLgBgaVcTvEx8mby8ogX2bgC4HBapH4yMwrz2FpoCuA17eocuUVMgEP6fnm83YpwSDTFrumw42bny/*)`
```python
self.nodes[1].createwallet(wallet_name="rawtr_multi", descriptors=True, blank=True)
rawtr_multi = self.nodes[1].get_wallet_rpc("rawtr_multi")
rawtr_multi_desc = "rawtr(tprv8ZgxMBicQKsPefef2Doobbq3xTCaVTHcDn6me82KSXY1vY9AJAWD5u7SDM4XGLfc4EoXRMFrJKpp6HNmQWA3FTMRQeEmMJYJ9RPqe9ne2hU/*, tprv8ZgxMBicQKsPezQ2KGArMRovTEbCGxaLgBgaVcTvEx8mby8ogX2bgC4HBapH4yMwrz2FpoCuA17eocuUVMgEP6fnm83YpwSDTFrumw42bny/*)#uv78hkt0"
result = rawtr_multi.importdescriptors([{"desc": rawtr_multi_desc, "active": True, "timestamp": "now"}])
print(rawtr_multi.listdescriptors(True))
```
This PR adds a check that prevents `rawtr` descriptors from being created if more than one key is entered, shows an error message, and adds a test for this case.

fa3f15f2dd94ae597a66037f5928fe4e90fe099d refactor: Avoid copies in FlatSigningProvider Merge (MacroFake)
Pull request description:
`Merge` will create several copies unconditionally:
* To initialize the args `a`, and `b`
* `ret`, which is the merge of the two args
So change the code to let the caller decide how many copies they need/want:
* `a`, and `b` must be explicitly moved or copied by the caller
* `ret` is no longer needed, as `a` can be used for it in place "for free"

This is a refactor, putting the burden to think about thread safety to
the caller. Otherwise, there is a risk that the caller will assume
thread safety where none exists, as is evident in the previous two
commits.

Now that we have descriptors there is no need to try to sign for a scriptPubKey using dummy signatures, and using a mocked verification of this witness against the interpreter, just to make sure we know how to spend such a Script.

a23cca56c0a7f4a267915b4beba3af3454c51603 refactor: Replace BResult with util::Result (Ryan Ofsky)
Pull request description:
Rename `BResult` class to `util::Result` and update the class interface to be more compatible with `std::optional` and with a full-featured result class implemented in https://github.com/bitcoin/bitcoin/pull/25665. Motivation for this change is to update existing `BResult` usages now so they don't have to change later when more features are added in https://github.com/bitcoin/bitcoin/pull/25665.
This change makes the following improvements originally implemented in https://github.com/bitcoin/bitcoin/pull/25665:
- More explicit API. Drops potentially misleading `BResult` constructor that treats any bilingual string argument as an error. Adds `util::Error` constructor so it is never ambiguous when a result is being assigned an error or non-error value.
- Better type compatibility. Supports `util::Result<bilingual_str>` return values to hold translated messages which are not errors.
- More standard and consistent API. `util::Result` supports most of the same operators and methods as `std::optional`. `BResult` had a less familiar interface with `HasRes`/`GetObj`/`ReleaseObj` methods. The Result/Res/Obj naming was also not internally consistent.
- Better code organization. Puts `src/util/` code in the `util::` namespace so naming reflects code organization and it is obvious where the class is coming from. Drops "B" from name because it is undocumented what it stands for (bilingual?)
- Has unit tests.

fadd8b2676f6d68ec87189871461c9a6a6aa3cac addrman: Use system time instead of adjusted network time (MarcoFalke)
Pull request description:
This changes addrman to use system time for address relay instead of the network adjusted time.
This is an improvement, because network time has multiple issues:
* It is non-monotonic, even if the system time is monotonic.
* It may be wrong, even if the system time is correct.
* It may be wrong, if the system time is wrong. For example, when the node has limited number of connections (`4`), or the system time is wrong by too much (more than +-70 minutes), or the system time only got wrong after timedata collected more than half of the entries while the time was correct, ...)
This may slightly degrade addr relay for nodes where timedata successfully adjusted the time. Addr relay can already deal with minor offsets of up to 10 minutes. Offsets larger than this should still allow addr relay and not result in a DoS.

- Pass in max_size_bytes parameter to InitS*Cache(), modify log line to
no longer allude to maxsigcachesize being split evenly between the two
validation caches.
- Fix possible integer truncation and add a comment.
[META] I've kept the integer types as int64_t in order to not introduce
unintended behaviour changes, in the next commit we will make
them size_t.
Returning the approximate total size eliminates the need for
InitS*Cache() to do nElems*sizeof(uint256). The cuckoocache has a better
idea of this information.
In src/test/fuzz/script_sigcache.cpp, we should really be setting up a
full working BasicTestingSetup. The initialize_ function is only run
once anyway.
In src/test/txvalidationcache_tests.cpp, the Dersig100Setup inherits
from BasicTestingSetup, which should have already set up a global script
execution cache without the need to explicitly call
InitScriptExecutionCache.

dd065dae9fcebd6806ff67703ffa8128e80b97cc refactor: Make mapBlocksUnknownParent local, and rename it (Hennadii Stepanov)
Pull request description:
This PR is a second attempt at #19594. This PR has two motivations:
- Improve code hygiene by eliminating a global variable, `mapBlocksUnknownParent`
- Fix fuzz test OOM when running too long ([see #19594 comment](https://github.com/bitcoin/bitcoin/pull/19594#issuecomment-958801638))
A minor added advantage is to release `mapBlocksUnknownParent` memory when the reindexing phase is done. The current situation is somewhat similar to a memory leak because this map exists unused for the remaining lifetime of the process. It's true that this map should be empty of data elements after use, but its internal metadata (indexing structures, etc.) can have non-trivial size because there can be many thousands of simultaneous elements in this map.
This PR helps our efforts to reduce the use of global variables. This variable isn't just global, it's hidden inside a function (it looks like a local variable but has the `static` attribute).
This global variable exists because the `-reindex` processing code calls `LoadExternalBlockFile()` multiple times (once for each block file), but that function must preserve some state between calls (the `mapBlocksUnknownParent` map). This PR fixes this by allocating this map as a local variable in the caller's scope and passing it in on each call. When reindexing completes, the map goes out of scope and is deallocated.
I tested this manually by reindexing on mainnet and signet. Also, the existing `feature_reindex.py` functional test passes.
