c457fb144c improve clarity and up max ipv6 ASNs (Baas)
Pull request description:
This PR attempts to address some of the areas of improvement raised in #17020 . Concretely, my proposed change is fairly minor but addresses the following changes to [`makeseeds.py`](https://github.com/bitcoin/bitcoin/blob/master/contrib/seeds/makeseeds.py):
- Increase max seeds per ASN for IPv6 to 10 as recommended [here](https://github.com/bitcoin/bitcoin/pull/16999#issuecomment-536999544), while keeping max seeds per ASN for IPv4 at 2.
- Bump `MIN_BLOCKS` to 730000.
- Improved script clarity: added function types and more docs to functions, added progress indicator when performing ASN lookup, and change string formatting to better align with [bitcoin python style guidelines](https://github.com/bitcoin/bitcoin/blob/master/test/functional/README.md#style-guidelines)
With the different ASN limits for IPv4 and IPv6, and the new minimum block requirement, the current stats look look like:
```
IPv4 IPv6 Onion Pass
470689 73238 0 Initial
470689 73238 0 Skip entries with invalid address
470689 73238 0 After removing duplicates
470688 73238 0 Skip entries from suspicious hosts
6098 1676 0 Enforce minimal number of blocks
5252 1443 0 Require service bit 1
3812 898 0 Require minimum uptime
3738 877 0 Require a known and recent user agent
3715 869 0 Filter out hosts with multiple bitcoin ports
512 512 0 Look up ASNs and limit results per ASN and per net
```
The new ASN max seeds of 10 allows for 512 IPv6 addresses to be included, up from the ~150 that was filtered by the previous version.
While there is more to do for #17020 , these changes I think are fairly isolated from the rest and should make it a bit easier for others to get up to speed with what the functions in the script do.

Pull request description:
This PR adds a very basic test for the signet miner script (contrib/signet/miner). ~~It was based on #24553 (merged by now) which fixes a bug (and was also the motivation to write this test).~~
The test roughly follows the steps from https://en.bitcoin.it/wiki/Signet#Custom_Signet, except that the challenge key-pair is created solely with the test framework. Calibration is also skipped, the difficulty is simply set to the first mainnet target `0x1d00ffff` (see also https://bitcoin.stackexchange.com/a/57186).

This refactor request was added in commit eb306664e7, though it didn't explain why the refactor is needed and what the goal is. Given that this wasn't touched for more than 5 years, it doesn't seem critical. Generally, non-trivial `TODO`s make more sense as GitHub issues, so that they can be discussed and triaged more easily.

457148a803 guix: fix GCC 10.3.0 + mingw-w64 setjmp/longjmp issues (fanquake)
Pull request description:
This commit backports [a patch](https://gcc.gnu.org/git/?p=gcc.git;a=commit;h=e8d1ca7d2c344a411779892616c423e157f4aea8) to the GCC 10.3.0 we build for Windows
cross-compilation in Guix. The commit has been [backported to the GCC
releases/gcc-10 branch](https://gcc.gnu.org/git/?p=gcc.git;a=commit;h=e3abcc56d2604b9d2652b615ff9e68981cb7f79e), but hasn't yet made it into a 10.x release.
The patch corrects a regression from an earlier GCC commit, see:
https://gcc.gnu.org/git/?p=gcc.git;a=commit;h=357c4350680bf29f0c7a115424e3da11c53b5582
and
https://gcc.gnu.org/git/?p=gcc.git;a=commit;h=074226d5aa86cd3de517014acfe34c7f69a2ccc7,
related to the way newer versions of mingw-w64 implement setjmp/longjmp.
Ultimately this was causing a crash for us when Windows users were
viewing the network traffic tab inside the GUI. After some period, long
enough that a buffer would need reallocating, a call into FreeTypes
[`gray_record_cell()`](a18906091c/src/smooth/ftgrays.c (L526)) would result in a call to [`ft_longjmp` (longjmp)](a18906091c/src/smooth/ftgrays.c (L165)), which
would then trigger a crash.
Fixes: https://github.com/bitcoin-core/gui/issues/582.

a4f4f89815 Replace uint256 specific implementations of base_uint::GetHex() and base_uint::SetHex() with proper ones that don't depend on uint256 and replace template methods instantiations of base_uint with template class instantiation (Samer Afach)
Pull request description:
The current implementations of `SetHex()` and `GetHex()` in `base_uint` use `arith_uint256`'s implementations. Which means, any attempt to create anything other than `arith_uint256` (say `arith_uint512`) and using any of these functions (which is what I needed in my application) will just not work and will cause compilation errors (besides the immediate linking errors due to templates being in source files instantiated only for 256) because there's no viable conversion from `arith_uint256` and any of the other possible types. Besides that these function will yield wrong results even if the conversion is possible depending on the size. This is fixed in this PR.

Alternative approaches could be to use Python instead of git grep (I'm not sure how) or use ```pylint --disable=all --enable=W0102```, though that requires installation of pylint.

494455f8a5 test: use MiniWallet for feature_fee_estimation.py (Sebastian Falbesoner)
Pull request description:
This PR enables one more of the non-wallet functional tests (feature_fee_estimation.py) to be run even with the Bitcoin Core wallet disabled by using the MiniWallet instead, as proposed in https://github.com/bitcoin/bitcoin/issues/20078. It takes use of the recently introduced methods `{create,send}_self_transfer_multi` (#24637) which allows to specify multiple UTXOs to be spent rather than only one. Very likely the test can still be simplified (e.g. coin selection in `small_txpuzzle_randfee`), but this is a first step.

Pull request description:
The motivation for this bump is some small build cleanups, including [dropping the `--enable-experimental`](80cf4eea5f) flag from the libsecp configure invocation, as well as some [now-redundant](https://github.com/bitcoin-core/secp256k1/pull/1090) `pkg-config` variable exporting from our own configure. We also get the benefit of a slightly more efficient libsecp configure due to https://github.com/bitcoin-core/secp256k1/pull/1088.
This also includes a change in our code to migrate from using the [now deprecated](99e6568fc6) `secp256k1_schnorrsig_sign` to `secp256k1_schnorrsig_sign32`.

4394733331 Add DEBUG_LOCKCONTENTION documentation to the developer notes (Jon Atack)
39a34b6877 Put lock logging behind DEBUG_LOCKCONTENTION preprocessor directive (Jon Atack)
Pull request description:
This is a more minimal, no-frills version of #24734 for backport. The other fixes and improvements in that pull can be done after.
*Copy of the PR 24734 description:*
PRs #22736, #22904 and #23223 changed lock contention logging from a `DEBUG_LOCKCONTENTION` compile-time preprocessor directive to a runtime `lock` log category and improved the logging output. This changed the locking from using `lock()` to `try_lock()`:
- `void Mutex::UniqueLock::lock()` acquires the mutex and blocks until it gains access to it
- `bool Mutex::UniqueLock::try_lock()` doesn't block but instead immediately returns whether it acquired the mutex; it may be used by `lock()` internally as part of the deadlock-avoidance algorithm
In theory the cost of `try_lock` might be essentially the [same](https://www.erisian.com.au/bitcoin-core-dev/log-2022-03-31.html#l-697) relative to `lock`. The test-and-set logic of these calls is purported to be ~ constant time, optimised and light/quick if used carefully (i.e. no mutex convoying), compared to system calls, memory/cache coherency and fences, wait queues, and (particularly) lock contentions. See the discussion around https://github.com/bitcoin/bitcoin/pull/22736#issuecomment-902851054 and after with respect to performance/cost aspects. However, there are reasonable concerns (see [here](https://github.com/bitcoin/bitcoin/pull/22736#discussion_r691277896) and [here](https://www.erisian.com.au/bitcoin-core-dev/log-2022-03-31.html#l-620)) that `Base::try_lock()` may be potentially [costly](https://www.erisian.com.au/bitcoin-core-dev/log-2022-03-31.html#l-700) or [risky](https://github.com/bitcoin/bitcoin/pull/22904#issuecomment-930484001) compared to `Base::lock()` in this very frequently called code.
One alternative to keep the run-time lock logging would be to gate the `try_lock` call behind the logging conditional, for example as proposed in ccd73de1dd and ACKed [here](https://github.com/bitcoin/bitcoin/pull/22736#issuecomment-901980815). However, this would add the [cost](https://github.com/bitcoin/bitcoin/pull/22736#issuecomment-910102353) of `if (LogAcceptCategory(BCLog::LOCK))` to the hotspot, instead of replacing `lock` with `try_lock`, for the most frequent happy path (non-contention).
It turns out we can keep the advantages of the runtime lock contention logging (the ability to turn it on/off at runtime) while out of prudence putting the `try_lock()` call and `lock` logging category behind a `DEBUG_LOCKCONTENTION` compile-time preprocessor directive, and also still retain the lock logging enhancements of the mentioned PRs, as suggested in https://github.com/bitcoin/bitcoin/pull/24734#issuecomment-1085785480 by W. J. van der Laan, in https://github.com/bitcoin/bitcoin/pull/22736#discussion_r691280693, and in the linked IRC discussion.
Proposed here and for backport to v23.
