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.

Pull request description:
Build against glibc 2.27 for all Linux builds (previously only used for RISC-V), and at the same time, increase our minimum required glibc to 2.27 (2018). This would drop support for Ubuntu Xenial (16.04) & Debian Stretch (9), from the produced release binaries. Compiling from source on those systems may be possible, assuming you can install a recent enough compiler/toolchain etc.

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.

14ce84388f02564c9e6d3cbd8e50aa85dbc1428b doc: add new NO_* options from #26833 (fanquake)
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`.

0bd73e2c453e8a88312edf43d184c33109f12ad6 util: Add -shutdownnotify option. (klementtan)
Pull request description:
**Description**: Similar to `-startupnotify`, this PR adds a new option to allow users to specify a command to be executed when Bitcoin Core shuts down.
**Note**: The `shutdownnotify` commands will not be executed if bitcoind shut down due to *unexpected* reasons (ie `killall -9 bitcoind`).
### 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
```

8c5b3646b5afe8a61f5c66478d8e11f0d2ce5108 Relax MIN_STANDARD_TX_NONWITNESS_SIZE to 65 non-witness bytes (Greg Sanders)
Pull request description:
Since the original fix was set to be a "reasonable" transaction to reduce allocations and the true motivation later revealed, it makes sense to relax this check to something more principled.
There are more exotic transaction patterns that could take advantage of a relaxed requirement, such as 1 input, 1 output OP_RETURN to burn a utxo to fees for CPFP purposes when change isn't practical.
Two changes could be accomplished:
1) Anything not 64 bytes could be allowed
2) Anything above 64 bytes could be allowed
In the Great Consensus Cleanup, suggestion (2)
was proposed as a consensus change, and is the simpler of the two suggestions. It would not allow an "empty" OP_RETURN but would reduce the required padding from 22 bytes to 5.
The functional test is also modified to test the actual case
we care about: 64 bytes
