1914e470e3 build: copy config.{guess,sub} post autogen in zmq package (fanquake)
Pull request description:
Otherwise our config.guess and config.sub will be copied over. This problem has been masked by the fact that modern systems ship with versions that recognise all the triplets we use (namely arm64-apple-darwin). However building on ubuntu 20.04 surfaces the issue.
Fixes#26420.

581f16ef34 Apply default umask in `SetupEnvironment()` (Hennadii Stepanov)
8a6219e543 Remove `-sysperms` option (Hennadii Stepanov)
Pull request description:
On master (1e7564eca8) docs say:
```
$ ./src/bitcoind -help | grep -A 3 sysperms
-sysperms
Create new files with system default permissions, instead of umask 077
(only effective with disabled wallet functionality)
```
Basing on that, one could expect that running `bitcoind` first time will create data directory and `wallets/` subdirectory with safe 0700 permissions.
But that is not the case:
```
$ stat .bitcoin | grep id
Access: (0775/drwxrwxr-x) Uid: ( 1000/ hebasto) Gid: ( 1000/ hebasto)
$ stat .bitcoin/wallets | grep id
Access: (0775/drwxrwxr-x) Uid: ( 1000/ hebasto) Gid: ( 1000/ hebasto)
```
Both directories, in fact, are created with system default permissions.
With this PR:
```

1c07500dbb contrib: make DNS seeds file an argument in CLI (brunoerg)
Pull request description:
Instead of using `makeseeds.py` this way:
```sh
python3 makeseeds.py -a asmap-filled.dat < seeds_main.txt > nodes_main.txt
```
We could use the DNS seeds file as an argument since it is a required one. It improves the way the script handles it when that file is missing as well as makes this script more friendly.
E.g:
```sh
python3 makeseeds.py -a asmap-filled.dat -s seeds_main.txt > nodes_main.txt
```

935acdcc79 refactor: modernize the implementation of uint256.* (pasta)
Pull request description:
- Constructors of uint256 to utilize Span instead of requiring a std::vector
- converts m_data into a std::array
- Prefers using `WIDTH` instead of `sizeof(m_data)`
- make all the things constexpr
- replace C style functions with c++ equivalents
- memset -> std::fill
This may also be replaced by std::memset, but I think that std::fill is more idiomatic of modern c++ and readable.
- memcpy -> std::copy
Note: In practice, implementations of std::copy avoid multiple assignments and use bulk copy functions such as std::memmove if the value type is TriviallyCopyable and the iterator types satisfy LegacyContiguousIterator. (https://en.cppreference.com/w/cpp/algorithm/copy)
This could also likely be replaced by std::memcpy, but as said above, I believe the using std::copy is the more c++ way to do anything and is almost guaranteed to compile to the same asm
- memcmp -> std::memcmp

fe683f3524 log: Log VerifyDB Progress over multiple lines (Martin Zumsande)
61431e3a57 validation: Skip VerifyDB checks of level >=3 if dbcache is too small (Martin Zumsande)
Pull request description:
This is the first two commits from #25574, leaving out all changes to `-verifychain` error-handling :
- The Problem of [25563](https://github.com/bitcoin/bitcoin/issues/25563) is that when we skip blocks at level 3 due to an insufficient dbcache (skipping some `DisconnectBlock()` calls), we would still attempt the level 4 checks, attempting to reconnect a block that was never disconnected, leading to an assert in `ConnectBlock()`.
Fix this by not attempting level 4 checks in this case.
- Logging of verification progress is now split over multiple lines. This is more verbose, but now each update has its own timestamp, and other threads logging concurrently will no longer lead to mangled output.
This can be tested with a small `dbcache` value, for example:
`bitcoind -signet -dbcache=10`
`bitcoin-cli -signet verifychain 4 1000`

One test case uses snprintf to convert an
int to a string. Change it to use ToString
(which uses a locale-independent version of
std::to_string). Also remove unnecessary
parts of StringContentsSerializer.
The descriptor inference logic would previously always use a dummy
signing provider and would never analyze the witness script of a P2WSH
scriptPubKey.
Note even a valid Miniscript might not always be decodable from Script
without more contextual information (for instance the key preimage for a
pk_h).

576f7b8614 Fix misleading RPC console wallet message (John Moffett)
Pull request description:
## Misleading message from RPCConsole window ##
In certain circumstances, the GUI console will display the message 'Executing command without any wallet' when it is, in fact, using the currently loaded wallet. For instance:
![scr3](https://user-images.githubusercontent.com/116917595/211404066-d49a6cbf-d3c3-4e89-8720-3583c6acf521.gif)
In RPC calls, if no wallet is explicitly selected and there is exactly one wallet loaded, the [default](39363a4b94/src/wallet/rpc/util.cpp (L71-L93)) is to act on that loaded wallet.
The GUI console acts that way in reality, but sometimes erroneously reports that it's not acting on any particular wallet. The root issue is due to the logic that prevents changing the selected wallet if the RPCConsole is visible:
39363a4b94/src/qt/rpcconsole.cpp (L783-L786)
This PR removes that unnecessary logic. This does have some ramifications. Prior to this PR, if a user opened the console window without any wallets loaded, then opened two or more wallets, the RPC console would select "None" of the wallets and any wallet-specific RPCs would fail. However, the behavior was different if the user hadn't had the console window open. In that case, if they opened the RPC Console window _after_ loading at least the first wallet, it would select the first-loaded wallet. This context-dependent behavior is (IMO) undesirable, and this PR changes it to be consistent.

08209c039f Correctly limit overview transaction list (John Moffett)
Pull request description:
Fixes#703
The way the main overview page limits the number of transactions displayed (currently 5) is not an appropriate use of Qt. Our subclassed transaction sort/filter proxy model returns a maximum of `5` in `rowCount()`. However, the model itself actually may hold significantly more. While this has _worked_, it breaks the contract of `rowCount()`.
If `bitcoin-qt` is run with a DEBUG build of Qt, it'll result in an assert-crash in certain relatively common situations (see #703 for details). Instead of artificially limiting the `rowCount()` in the subclassed filter, we can hide/unhide the rows in the displaying `QListView` upon any changes in the sorted proxy filter.
I loaded a wallet with 20,000 transactions and did not notice any performance differences between master and this branch.
For reference, this is the list I'm referring to:

fa47b28dfc refactor: Remove unused CDataStream SerializeMany constructor (MarcoFalke)
Pull request description:
Seems odd to have an unused method. Moreover, the function is fragile and dangerous, because one could have a `std::vector vec_a` and type `CDataStream{vec_a, 0, 0}.size()` and `CDataStream{0, 0, vec_a}.size()`, assuming they are the same thing, when in fact they are not. (The first takes over the memory as is, the second serializes the vector).
So my suggestion would be to remove the unused method and introduce a new method when this functionality is needed. For example: `static DataStream FromMany(Args&&... args)`.

71383f2fad ci: avoid using -Werror for older compilers (fanquake)
Pull request description:
Don't enable `-Werror` (in the CI) for compilers at least older than our current release compiler (GCC 10). It provides little-to-no value, other than turning compiler bugs & false positives into build failures, and we aren't going to mutate perfectly fine/working code, for the sake of avoid a warning that shouldn't even exist.
I also do not see the point of playing whack-a-mole and turning off various warnings/trying to further work around the broken compiler, just to acheive warningless builds for the sake of warningless builds.

59cc66abb9 test: Remove AddrMan unit test that fails consistency checks (Martin Zumsande)
Pull request description:
Two fixups for #26847:
* Now that `AddrMan::Size()` performs internal consistency tests (it didn't before), we can't call it in the `load_addrman_corrupted` unit tests, where we deal with an artificially corrupted `AddrMan`. This would fail the test when using `-checkaddrman=1` (leading to spurious CI fails). Therefore remove the tests assertion, which is not particularly helpful anyway (in production we abort init when peers.dat is corrupted instead of querying AddrMan in its corrupted state).
(See https://github.com/bitcoin/bitcoin/pull/26847#issuecomment-1411458339)

Don't enable `-Werror` (in the CI) for compilers at least older than
our current release compiler (GCC 10). It provides little-to-no value,
other than turning compiler bugs & false positives into build failures,
and we aren't going to mutate perfectly fine/working code, for the sake
of avoid a warning that shouldn't even exist.
I also do not see the point of playing whack-a-mole and turning off various
warnings/trying to further work around the broken compiler, just to
acheive warningless builds for the sake of warningless builds.
One anecdote from "How SQLite Is Tested":

> exceptions. More bugs have been introduced into SQLite while trying
> to get it to compile without warnings than have been found by static

Now that Size() performs internal consistency checks,
it will rightfully fail (and assert) when dealing with
a corrupted AddrMan. Therefore remove this check.
87f11ef47f refactor: use `Hash` helper for double-SHA256 calculations (Sebastian Falbesoner)
Pull request description:
We have two helper templates `Hash(const T& in1)` and `Hash(const T& in1, const T& in2)` available for calculating the double-SHA256 hash of one object or two concatenated objects, respectively:
b5868f4b1f/src/hash.h (L74-L89)
This PR uses them in order to increase readability and simplify the code. As in #15294 (which inspired this PR, doing the same for RIPEMD160), the helper is not utilized in validation.cpp and script/interpreter.cpp to avoid touching consensus-relevant code.

7a820cee0e test, build: Separate `read_json` function into its own module (Hennadii Stepanov)
Pull request description:
Currently, 4 source files rely on the definition of the `read_json` function provided in `src/test/script_tests.cpp`.
This PR breaks this entanglement, improves code structure and maintainability.

dfc01ccd73 net: simplify the call to vProcessMsg.splice() (Vasil Dimov)
Pull request description:
At the time when
```cpp
pnode->vProcessMsg.splice(pnode->vProcessMsg.end(), pnode->vRecvMsg, pnode->vRecvMsg.begin(), it);
```
is called, `it` is certainly `pnode->vRecvMsg.end()` which makes the call equivalent to:
```cpp
pnode->vProcessMsg.splice(pnode->vProcessMsg.end(), pnode->vRecvMsg, pnode->vRecvMsg.begin(), pnode->vRecvMsg.end());
```
which is equivalent to:
```cpp
pnode->vProcessMsg.splice(pnode->vProcessMsg.end(), pnode->vRecvMsg);
```
Thus, use the latter. Further, maybe irrelevant, but the latter has constant complexity while the original code is `O(length of vRecvMsg)`.

c77c877a8e net: Load fixed seeds from reachable networks for which we don't have addresses (Martin Zumsande)
d35595a78a addrman: add function to return size by network and table (Martin Zumsande)
Pull request description:
AddrMan currently doesn't track the number of its entries by network, it only knows the total number of addresses. This PR makes AddrMan keep track of these numbers, which would be helpful for multiple things:
1. Allow to specifically add fixed seeds to AddrMan of networks where we don't have any addresses yet - even if AddrMan as a whole is not empty (partly fixing #26035). This is in particular helpful if the user abruptly changes `-onlynet` settings (such that addrs that used to be reachable are no longer and vice versa), in which case they currently could get stuck and not find any outbound peers. The second commit of this PR implements this.
1. (Future work): Add logic for automatic connection management with respect to networks - such as making attempts to have at least one connection to each reachable network as suggested [here](https://github.com/bitcoin/bitcoin/issues/26035#issuecomment-1249420209). This would involve requesting an address from a particular network from AddrMan, and expanding its corresponding function `AddrMan::Select()` to do this requires internal knowledge of the current number of addresses for each network and table to avoid getting stuck in endless loops.
1. (Future work): Perhaps display the totals to users. At least I would find this helpful to debug, the existing option (`./bitcoin-cli -addrinfo`) is rather indirect by doing the aggregation itself in each call, doesn't distinguish between new and tried, and being based on `AddrMan::GetAddr()` it's also subject to a quality filter which we probably don't want in this spot.
