a518fff0f2e479064dd4cff6c29fb54c72c1407b rest: add verbose and mempool_sequence query params for mempool/contents (Andrew Toth)
Pull request description:
The verbose mempool json response can get very large. This adds an option to return the non-verbose response of just the txids. It is identical to the rpc response so the diff here is minimal. This also adds the mempool_sequence parameter for rpc consistency. Verbose defaults to true to remain backwards compatible.
It uses query parameters to be compatible with the efforts in https://github.com/bitcoin/bitcoin/issues/25752.

Pull request description:
References to `utilstrencodings` and `lint-locale-dependence.sh` where incorrect, updating them accordingly.
Also, adding another reference to util function [`LocaleIndependentAtoi`](https://github.com/bitcoin/bitcoin/blob/master/src/util/strencodings.h#L108-L118), which is related with the updated section of the guide:
```
// LocaleIndependentAtoi is provided for backwards compatibility reasons.
//
// New code should use ToIntegral or the ParseInt* functions
// which provide parse error feedback.
//
// The goal of LocaleIndependentAtoi is to replicate the defined behaviour of
// std::atoi as it behaves under the "C" locale, and remove some undefined
// behavior. If the parsed value is bigger than the integer type's maximum
// value, or smaller than the integer type's minimum value, std::atoi has
// undefined behavior, while this function returns the maximum or minimum
// values, respectively.

Pull request description:
Adds a paragraph to the clang-tidy section explaining how to de-noise its output. By default clang-tidy will print errors arrising from included headers in leveldb and other dependencies. By passing `--enable-suppress-external-warnings` flag to configure, errors arising from external dependencies are suppressed. Additional errors arrising from internal dependencies such as leveldb are suppressed by passing the `src/.bear-tidy-config` configuration file to bear. This file includes exclusionary rules for leveldb.

---
When a user activates a snapshot, the serialized UTXO set data is used to create an "assumed-valid" chainstate, which becomes active in an attempt to get the node to network tip as quickly as possible. Simultaneously in the background, the already-existing chainstate continues "conventional" IBD to both accumulate full block data and serve as a belt-and-suspenders to validate the assumed-valid chainstate.
Once the background chainstate's tip reaches the base block of the snapshot used, we set `m_stop_use` on that chainstate and immediately take the hash of its UTXO set; we verify that this matches the assumeutxo value in the source code. Note that while we ultimately want to remove this background chainstate, we don't do so until the following initialization process, when we again check the UTXO set hash of the background chainstate, and if it continues to match, we remove the (now unnecessary) background chainstate, and move the (previously) assumed-valid chainstate into its place. We then reinitialize the chainstate in the normal way.
As noted in previous comments, we could do the filesystem operations "inline" immediately when the background validation completes, but that's basically just an optimization that saves disk space until the next restart. It didn't strike me as worth the risk of moving chainstate data around on disk during runtime of the node, though maybe my concerns are overblown.
The final result of this completion process is a fully-validated chain, where the only evidence that the user synced using assumeutxo is the existence of a `base_blockhash` file in the `chainstate` directory.

04f270b4358417fc2827b9f91717816062b1864e Add test for unspendable transactions and parameter 'maxburnamount' to sendrawtransaction. (David Gumberg)
Pull request description:
This PR adds a user configurable, zero by default parameter — `maxburnamount` — to `sendrawtransaction`. This PR makes bitcoin core reject transactions that contain unspendable outputs which exceed `maxburnamount`. closes#25899.
As a result of this PR, `sendrawtransaction` will by default block 3 kinds of transactions:
1. Those that begin with `OP_RETURN` - (datacarriers)
2. Those whose lengths exceed the script limit.
3. Those that contain invalid opcodes.
The user is able to configure a `maxburnamount` that will override this check and allow a user to send a potentially unspendable output into the mempool.
I see two legitimate use cases for this override:
1. Users that deliberately use `OP_RETURN` for datacarrier transactions that embed data into the blockchain.
2. Users that refuse to update, or are unable to update their bitcoin core client would be able to make use of new opcodes that their client doesn't know about.

Pull request description:
`VerifyDB()` can fail to complete due to insufficient dbcache at the level 3 checks. This PR improves the error handling in this case in the following ways:
- The rpc `-verifychain` now returns false if the check can't be completed due to insufficient cache
- During init, we only log a warning if the default values for `-checkblocks` and `-checklevel` are taken and the check doesn't complete. However, if the user actively specifies one of these args, we return with an InitError if we can't complete the check.
This PR also changes `-verifychain` RPC to return `false` if the verification didn't finish due to missing block data (pruning) or due to being interrupted by the node being shutdown.
Previously, this PR also included a fix for a possible assert during verification - this was done in #27009 (now merged).

and remove m_snapshot_validated. This state can now be inferred by the
number of isUsable chainstates.
m_disabled is used to signal that a chainstate should no longer be used
by validation logic; it is used as a sentinel when background validation
completes or if the snapshot chainstate is found to be invalid.
isUsable is a convenience method that incorporates m_disabled.

75347236f212f327a5bba10d8a900cc58ebe5de0 docs: document c-style cast prohibition (Pasta)
Pull request description:
In the words of practicalswift:
```
A C-style cast is equivalent to try casting in the following order:
const_cast(...)
static_cast(...)
const_cast(static_cast(...))
reinterpret_cast(...)
const_cast(reinterpret_cast(...))
By using static_cast<T>(...) explicitly we avoid the possibility of an unintentional and
dangerous reinterpret_cast. Furthermore static_cast<T>(...) allows for easier grepping of casts.
For a more thorough discussion, see "ES.49: If you must use a cast, use a named cast"
in the C++ Core Guidelines (Stroustrup & Sutter).
```
Modern tooling, specifically `-Wold-style-cast` can enable us to enforce never using C-style casts. I believe this is especially important due to the number of C-style casts the codebase is currently being used as a reinterpret_cast. reinterpret_casts are especially dangerous, and should never be done via C-style casts.
Update the docs to suggest the use of named cast or functional casts.

Pull request description:
Now that we can build a bdb-only depends prefix (#26833), there is no need to
maintain a bdb-building bash script, that does the same thing as
depends, except worse, as it's missing patches and workarounds. i.e #26623.
Someone that wants to compile bdb themselves, but doesn't want to use other depends built libs, can do:
```bash
make -C depends NO_BOOST=1 NO_LIBEVENT=1 NO_QT=1 NO_SQLITE=1 NO_NATPMP=1 NO_UPNP=1 NO_ZMQ=1 NO_USDT=1
...
to: /path/to/bitcoin/depends/x86_64-pc-linux-gnu
```
which gives them a BDB only prefix, and then compile using:
```bash
export BDB_PREFIX="/path/to/bitcoin/depends/x86_64-pc-linux-gnu"
./autogen.sh
./configure \
BDB_LIBS="-L${BDB_PREFIX}/lib -ldb_cxx-4.8" \
BDB_CFLAGS="-I${BDB_PREFIX}/include"
```
Wondering if we should extract the build bdb/legacy wallet docs somewhere, to avoid the repetition?

1134686ef92fb622ac32dc7463d3763cf18c85ad mempool: Don't share mempool with dbcache in blocksonly (willcl-ark)
Pull request description:
Fixes#9526
When `-blocksonly` has been set reduce default mempool size to avoid surprising resource usage via sharing un-used mempool cache space with dbcache.
In comparison to https://github.com/bitcoin/bitcoin/pull/9569 which either set `maxmempool` size to 0 when `-blocksonly` was set or else errored on startup, this change will permit `maxmempool` options being set.
This preserves the current (surprising?) behaviour of having a functional mempool in `-blocksonly` mode, to permit whitelisted peer transaction relay, whilst reducing average runtime memory usage for blocksonly nodes which either use the default settings or have otherwise configured a `maxmempool` size.
To use the previous old defaults node operators can configure their node with: `-blocksonly -maxmempool=300`.

### Testing:
**Normal shutdown commands**
```
# start bitcoind with shutdownnotify optioin
./src/bitcoind -signet -shutdownnotify="touch foo.txt"
# shutdown bitcoind
./src/bitcoin-cli -signet stop
# check that foo.txt has been created
```
**Final RPC call**
Commands:
```
$ ./src/bitcoind -signet -nolisten -noconnect -shutdownnotify="./src/bitcoin-cli -signet getblockchaininfo > tmp.txt"
$ ./src/bitcoin-cli stop
$ cat tmp.txt
