The comparison of m_best_invalid with the tip of the respective chainstate
makes no sense for the background chainstate, and can lead to incorrect
error messages.

The crash occurs because 'WalletController::removeAndDeleteWallet' is called
twice for the same wallet model: first in the GUI's button connected function
'WalletController::closeWallet', and then again when the backend emits the
'WalletModel::unload' signal.
This causes the issue because 'removeAndDeleteWallet' inlines an
erase(std::remove()). So, if 'std::remove' returns an iterator to the end
(indicating the element wasn't found because it was already erased), the
subsequent call to 'erase' leads to an undefined behavior.

Exercising and verifying the following points:
1. An IBD node can sync headers from an AssumeUTXO node at
any time.
2. IBD nodes do not request historical blocks from AssumeUTXO
nodes while they are syncing the background-chain.
3. The assumeUTXO node dynamically adjusts the network services
it offers according to its state.
4. IBD nodes can fully sync from AssumeUTXO nodes after they
finish the background-chain sync.

Because AssumeUTXO nodes prioritize tip synchronization, they relay their local
address through the network before completing the background chain sync.
This, combined with the advertising of full-node service (NODE_NETWORK), can
result in an honest peer in IBD connecting to the AssumeUTXO node (while syncing)
and requesting an historical block the node does not have. This behavior leads to
an abrupt disconnection due to perceived unresponsiveness (lack of response)
from the AssumeUTXO node.
This lack of response occurs because nodes ignore getdata requests when they do
not have the block data available (further discussion can be found in PR 30385).
Fix this by refraining from signaling full-node service support while the
background chain is being synced. During this period, the node will only
signal 'NODE_NETWORK_LIMITED' support. Then, full-node ('NODE_NETWORK')
support will be re-enabled once the background chain sync is completed.

Currently, builds of libevent in depends, using CMake, fail on some
systems, like Alpine, with the following:
```bash
/bitcoin/depends/work/build/aarch64-unknown-linux-musl/libevent/2.1.12-stable-1516ed47ea8/evmap.c: In function 'evmap_signal_add_':
/bitcoin/depends/work/build/aarch64-unknown-linux-musl/libevent/2.1.12-stable-1516ed47ea8/evmap.c:456:31: error: 'NSIG' undeclared (first use in this function)
456 | if (sig < 0 || sig >= NSIG)
```
From what I can tell the `_GNU_SOURCE` "detection" in libevents CMake build
system, never? really worked, and it's not clear what a nice fix is.
For now, always use `_GNU_SOURCE` when building libevent in depends.

the run_command test under system_tests fails if the locale is anything
other than English ones because results such as "No such file or directory"
will be different under Non-English locales.
On the old version, a `ls nonexistingfile` was used to generate the error
output which is not ideal. In the current version we are using a Python one-liner
to generate a non 0 zero return value and "err" on stderr and check the
expected value against this.

uptime requirements for Onion and I2P nodes

7a2068a0ff9eec2bab436b47eba37fd34b71bba4 seeds: Pull nodes from virtu's crawler (virtu)
Pull request description:
This builds on #30008 and adds data [exported](https://github.com/virtu/seed-exporter) by [my crawler](https://github.com/virtu/p2p-crawler) an additional source for seed nodes. Data covers all supported network types.
[edit: Added Luke's seeder as input as well.]
### Motivation
- Further decentralizes the seed node selection process (in the long term potentially enabling an _n_-source threshold for nodes to prevent a single source from entering malicious nodes)
- No longer need to manually curate seed node list for any network type: See last paragraph of OP in #30008. My crawler has been [discovering the handful of available cjdns nodes](https://21.ninja/reachable-nodes/nodes-by-net-type/) for around two months, all but one of which meet the reliability criteria.
- Alignment of uptime requirements for Onion and I2P nodes with those of clearnet nodes to 50%: If I'm reading the code correctly, seeders appear to optimize for up-to-dateness by using [lower connection timeouts](https://github.com/achow101/dnsseedrs/blob/3c1a63c6723819871d76fe0fbd2155fe5a5bb171/src/crawl.rs#L349) than [Bitcoin Core](https://github.com/bitcoin/bitcoin/blob/bc87ad98543299e1990ee1994d0653df3ac70093/src/netbase.cpp#L40C27-L40C48) to maximize throughput. Since my crawler does not have the same timeliness requirements, it opts for accuracy by using generous timeouts. As a result, its data contains additional eligible Onion (and other darknet nodes), as is shown in the histogram below. Around 4500 Onion nodes are discovered so far (blue); my data adds ~6400 more (orange); ~ 1500 nodes take longer than the default 20-second Bitcoin Core timeout and won't qualify as "good".
Here's the current results with 512 nodes for all networks except cjdns:

- [x] Regenerate mainnet seeds
- [x] Rebase, then remove WIP label once #30008 gets merged

Updates from Chain Interface
1b41d45d462d856a9d0b44ae0039bbb2cd78407c wallet: bugfix: ensure atomicity in settings updates (ismaelsadeeq)
Pull request description:
This PR fixes #30620.
As outlined in the issue, creating two wallets with `load_on_startup=true` simultaneously results in only one wallet being added to the startup file.
The current issue arises because the wallet settings update process involves:
1. Obtaining the settings value while acquiring the settings lock.
2. Modifying the settings value.
3. Overwriting the settings value while acquiring the settings lock again.
This sequence is not thread-safe. Different threads could modify the same base value simultaneously, overwriting data from other workers without realizing it.
The PR attempts to fix this by modifying the chain interface's `updateRwSetting` method to accept a function that will be called with the settings reference. This function will either update or delete the setting and return an enum indicating whether the settings need to be overwritten in this or not.
Additionally, this PR introduces two new methods to the chain interface:
- `overwriteRwSetting`: This method replaces the setting with a new value.
Used in `VerifyWallets`
- `deleteRwSettings`: This method completely erases a specified setting.
This method is currently used only in `overwriteRwSetting`.
These changes ensure that updates are race-free across all clients.

fa5b58ea01fac1adb6336b8b6b5217193295c695 test: Avoid intermittent block download timeout in p2p_ibd_stalling (MarcoFalke)
Pull request description:
Fixes #30704
The goal of the test is to check the stalling timeout, not the block download timeout.
On extremely slow hardware (for example qemu virtual hardware), downloading the 1023 blocks may take longer than the block download timeout.
Fix it by pinning the time using mocktime, and only advance it when testing the stalling timeout.

d5a8c4c4bd76f296f4d744184dc80a6a6a0731bd makeseeds: Update user agent regex (Ava Chow)
Pull request description:
The [DNS seeder](https://github.com/achow101/dnsseedrs) that I wrote collects statistics on node reliability in the same way that sipa's seeder does, and also outputs this information in the same file format. Thus it can also be used in our fixed seeds update scripts. My seeder additionally crawls onion v3, i2p, and cjdns, so will now be able to set those fixed seeds automatically rather than curating manual lists.
In doing this update, I've found that `makeseeds.py` is missing newer versions from the regex as well as cjdns support; both of these have been updated.
I also noticed that the testnet fixed seeds are all manually curated and sipa's seeder does not appear to publish any testnet data. Since I am also running the seeder for testnet, I've added the commands to generate testnet fixed seeds from my seeder's data too.
Lastly, I've updated all of the fixed seeds. However, since my seeder has not found any cjdns nodes that met the reliability criteria (possibly due to connectivity issues present in those networks), I've left the previous manual seeds for that network.

5b4f34006dbd76223b55b156421f87d2241ac296 devtools, utxo-snapshot: Fix block height out of range (pablomartin4btc)
Pull request description:
<details>
<summary>Fixing a <a href="https://github.com/bitcoin/bitcoin/pull/28553#pullrequestreview-2251032570">bug</a> in <code>utxo_snapshot.sh</code>.</summary>
```
/contrib/devtools/utxo_snapshot.sh 840000 snapshot2.dat ./src/bitcoin-cli -datadir=${AU_DATADIR}
Do you want to disable network activity (setnetworkactive false) before running invalidateblock? (Y/n):
Disabling network activity
false
error code: -8
error message:
Block height out of range
```
And the user will see the following in the node and it would stay there if not reset:
```

This is a "temporary" fix until #29553 gets merged, which will remove the script entirely.
Handle the "Block height out of range" error gracefully by checking if the node has synchronized to or beyond the required block height, otherwise without this validation the node would keep the network disabled if the user selected that option.
<details>
<summary>Provide a user-friendly message if the block height is out of range and exit the script cleanly.</summary>
```
/contrib/devtools/utxo_snapshot.sh 840000 snapshot2.dat ./src/bitcoin-cli -datadir=${AU_DATADIR}
Error: The node has not yet synchronized to block height 840001.
Please wait until the node has synchronized past this block height and try again.

Pull request description:
Builds on PR #30657.
Refactors `read_xor_key()` from `util.py` to `test_node.py` (comment https://github.com/bitcoin/bitcoin/pull/30657#discussion_r1723358327)
Adds a check that `xor.dat` is created when missing (comment https://github.com/bitcoin/bitcoin/pull/30657#discussion_r1717724161)
Help states:
```
-blocksxor
Whether an XOR-key applies to blocksdir *.dat files. The created XOR-key
will be zeros for an existing blocksdir or when `-blocksxor=0` is
set, and random for a freshly initialized blocksdir. (default: 1)
```

- Settings updates were not thread-safe, as they were executed in
three separate steps:
1) Obtain settings value while acquiring the settings lock.
2) Modify settings value.
3) Overwrite settings value while acquiring the settings lock.
This approach allowed concurrent threads to modify the same base value
simultaneously, leading to data loss. When this occurred, the final
settings state would only reflect the changes from the last thread
that completed the operation, overwriting updates from other threads.
Fix this by making the settings update operation atomic.
- Add test coverage for this behavior.
