c1144f0076 tests: Reset node context members on ~BasicTestingSetup (TheCharlatan)
9759af17ff shutdown: Destroy kernel last (TheCharlatan)
Pull request description:
The destruction/resetting of node context members in the tests should roughly follow the behavior of the `Shutdown` function in `init.cpp`.
This was originally requested by MarcoFalke in this [comment](https://github.com/bitcoin/bitcoin/pull/25065#discussion_r890161249) in response to the [original pull request](https://github.com/bitcoin/bitcoin/pull/25065) introducing the `kernel::Context`.

Currently the shutdown function resets the kernel before the
chainman and scheduler. Invert this order by resetting the kernel
last, since they might rely on the kernel.

64d6f77907 net: put CJDNS prefix byte in a constant (Vasil Dimov)
Pull request description:
`LookupSubNet()` would treat addresses that start with `fc` as IPv6 even if `-cjdnsreachable` is set. This creates the following problems where it is called:
* `NetWhitelistPermissions::TryParse()`: otherwise `-whitelist=` fails to white list CJDNS addresses: when a CJDNS peer connects to us, it will be matched against IPv6 `fc...` subnet and the match will never succeed.
* `BanMapFromJson()`: CJDNS bans are stored as just IPv6 addresses in `banlist.json`. Upon reading from disk they have to be converted back to CJDNS, otherwise, after restart, a ban entry like (`fc00::1`, IPv6) would not match a peer (`fc00::1`, CJDNS).
* `RPCConsole::unbanSelectedNode()`: in the GUI the ban entries go through `CSubNet::ToString()` and back via `LookupSubNet()`. Then it must match whatever is stored in `BanMan`, otherwise it is impossible to unban via the GUI.
These were uncovered by https://github.com/bitcoin/bitcoin/pull/26859.
Thus, flip the result of `LookupSubNet()` to CJDNS if the network base address starts with `fc` and `-cjdnsreachable` is set. Since subnetting/masking does not make sense for CJDNS (the address is "random" bytes, like Tor and I2P, there is no hierarchy) treat `fc.../mask` as an invalid `CSubNet`.
To achieve that, `MaybeFlipIPv6toCJDNS()` has to be moved from `net` to `netbase` and thus also `IsReachable()`. In the process of moving `IsReachable()`, `SetReachable()` and `vfLimited[]` encapsulate those in a class.

7fe537f7a4 Implement CCoinsViewErrorCatcher::HaveCoin (Aurèle Oulès)
Pull request description:
Attempt to fix #26112.
As suggested by sipa in https://github.com/bitcoin/bitcoin/issues/26112#issuecomment-1249683401:
> CCoinsViewErrorCatcher, the wrapper class used around CCoinsViewDB that's supposed to detect these problems and forcefully exit the application, has an override for GetCoins. But in CheckTxInputs, HaveInputs is first invoked, which on its turn calls HaveCoin. HaveCoin is implemented in CCoinsViewDB, but not in CCoinsViewErrorCatcher, and thus the disk read exception escapes.
> A solution may be to just add an override for HaveCoin in CCoinsViewErrorCatcher.
I implemented `CCoinsViewErrorCatcher::HaveCoin` and also added a periodic disk space check that shutdowns the node if there is not enough space left on disk, the minimum here is 50MB.
For reviewers, it's possible to saturate disk space to test the PR by creating large files with `fallocate -l 50G test.bin`

`vfLimited`, `IsReachable()`, `SetReachable()` need not be in the `net`
module. Move them to `netbase` because they will be needed in
`LookupSubNet()` to possibly flip the result to CJDNS (if that network
is reachable).
In the process, encapsulate them in a class.
`NET_UNROUTABLE` and `NET_INTERNAL` are no longer ignored when adding
or removing reachable networks. This was unnecessary.
Currently the logic is fragmented between init and connman. Encapsulating this
logic within connman allows for less mental overhead and easier reuse in tests.

When using an assumedvalid chainstate, only process validationinterface
callbacks from the background chainstate within indexes. This ensures
that all indexes are built in-order.
Later, we can possibly designate indexes which can be built out of order
and continue their operation during snapshot use.
Once the background sync has completed, restart the indexes so that
they continue to index the now-validated snapshot chainstate.

13eb8aa572 doc: Release notes for testnet defaulting to -acceptnonstdtxn=0 (Anthony Towns)

Pull request description:
Changes `-acceptnonstxtxn` to default to 0 on testnet, matching the other chains. Allowing non-standard txs on testnet by default contributed to the difficulties RSK described in #26348: "We see that there are two script paths and, to reduce the script size, a single CHECKMULTISIG is used for the two paths, separating the signer count from the CHECKMULTISIG opcode. This script worked on testnet, because it lacks the standard checks performed in Mainnet."

This more accurately captures the intent of limiting send buffer size, as
many small messages can have a larger overhead that is not counted with the
current approach.
It also means removing the dependency on the header size (which will become
a function of the transport choice) from the send buffer calculations.
Right now when we get the help for -torcontrol it says that there is a
default ip and port we dont specify if there is a specified ip that we
would also use port 9051 as default

Pull request description:
Some future work needs to touch things in script/standard.{h/cpp}, however it is unclear if it is safe to do so as they are included in several different places that could effect standardness and consensus. It contains a mix of policy parameters, consensus parameters, and utilities only used by the wallet. This PR breaks up the various components and renames the files to clearly separate everything.
* `CTxDestination` is moved to a new file `src/addresstype.{cpp/h}`
* `TaprootSpendData` and `TaprootBuilder` (and their utility functions and structs) are moved to `SigningProvider` as these are used only during signing.
* `CScriptID` is moved to `script/script.h` to be next to `CScript`.
* `MANDATORY_SCRIPT_VERIFY_FLAGS` is moved to `interpreter.h`
* The parameters `DEFAULT_ACCEPT_DATACARRIER` and `MAX_OP_RETURN_RELAY` are moved to `policy.h`
* `standard.{cpp/h}` is renamed to `solver.{cpp/h}` since that's all that's left in the file after the above moves

Pull request description:
Leveldb headers are currently included in the `dbwrapper.h` file and thus available to many of Bitcoin Core's source files. However, leveldb-specific functionality should be abstracted by the `dbwrapper` and does not need to be available to the rest of the code. Having leveldb included in a widely-used header such as `dbwrapper.h` bloats the entire project's header tree.
The `dbwrapper` is a key component of the libbitcoinkernel library. Future users of this library would not want to contend with having the leveldb headers exposed and potentially polluting their project's namespace.
For these reasons, the leveldb headers are removed from the `dbwrapper` by moving leveldb-specific code to the implementation file and creating a [pimpl](https://en.cppreference.com/w/cpp/language/pimpl) where leveldb member variables are indispensable. As a final step, the leveldb include flags are removed from the `BITCOIN_INCLUDES` and moved to places where the dbwrapper is compiled.

This change drops the last kernel dependency on shutdown.cpp. It also adds new
hooks for libbitcoinkernel applications to be able to interrupt kernel
operations when the chain tip changes.
This is a refactoring that does not affect behavior. (Looking at the code it
can appear like the new break statement in the ActivateBestChain function is a
change in behavior, but actually the previous StartShutdown call was indirectly
triggering a break before, because it was causing m_chainman.m_interrupt to be
true. The new code just makes the break more obvious.)
This has the benefit of moving the StartShutdown call out of the
blockstorage file and thus out of the kernel's responsibility. The user
can now decide if he wants to start shutdown / interrupt after a block
import or not.
At present, during init, we traverse the chain (once per index)
to confirm that all necessary blocks to sync each index up to
the current tip are present.
To make the process more efficient, we can fetch the oldest block
from the indexers and perform the chain data existence check from
that point only once.
This also moves the pruning violation check to the end of the
'loadinit' thread, which is where the reindex, block loading and
chain activation processes happen.
Making the node's startup process faster, allowing us to remove
the global g_indexes_ready_to_sync flag, and enabling the
execution of the pruning violation verification even when the
reindex or reindex-chainstate flags are enabled (which has being
skipped so far).
By moving the 'StartIndexes()' call into the 'initload'
thread, we can remove the threads active wait. Optimizing
the available resources.
The only difference with the current state is that now the
indexes threads will only be started when they can process
work and not before it.
No behavior change.
The goal here is to group indexes, so we can perform the same
initialization and verification process equally for all of them.
The checks performed inside `StartIndexes` will be expanded
in the subsequent commits.
The thread does not only load blocks, it loads the mempool and,
in a future commit, will start the indexes as well.
Also, renamed the 'ThreadImport' function to 'ImportBlocks'
And the 'm_load_block' class member to 'm_thread_load'.

sed -i "s/ThreadImport/ImportBlocks/g" $(git grep -l ThreadImport -- ':!/doc/')

-END VERIFY SCRIPT-
The mempool load can take a while, and it is not
needed for the indexes' synchronization.
Also, having the mempool load function call
inside 'blockstorage.cpp' wasn't structurally
correct.
FatalError replaces what previously was the AbortNode function in
shutdown.cpp.
This commit is part of the libbitcoinkernel project and further removes
the shutdown's and, more generally, the kernel library's dependency on
interface_ui with a kernel notification method. By removing interface_ui
from the kernel library, its dependency on boost is reduced to just
boost::multi_index. At the same time it also takes a step towards
de-globalising the interrupt infrastructure.
