Pull request description:
This PR:
1. Coalesce the Chainstate loading sequence between `AppInitMain` and `*TestingSetup` (which makes it more tested)
2. Makes the Chainstate loading sequence reusable in preparation for future work extracting out our consensus engine.
Code-wise, this PR:
1. Extracts `AppInitMain`'s Chainstate loading sequence into a `::LoadChainstateSequence` function
2. Makes this `::LoadChainstateSequence` function reusable by
1. Decoupling it from various concepts (`ArgsManager`, `uiInterface`, etc)
2. Making it report errors using an `enum` rather than by setting a `bilingual_str`
3. Makes `*TestingSetup` use this new `::LoadChainstateSequence`

dce8c4c381 rpc: getblockfrompeer (Sjors Provoost)
b884ababc2 rpc: move Ensure* helpers to server_util.h (Sjors Provoost)
Pull request description:
This adds an RPC method to fetch a block directly from a peer. This can used to fetch stale blocks with lower proof of work that are normally ignored by the node (`headers-only` in `getchaintips`).
Usage:
```
bitcoin-cli getblockfrompeer HASH peer_n
```
Closes#20155
Limitations:
* you have to specify which peer to fetch the block from
* the node must already have the header

1dcba996d3 Coinbase receivedby rpcs release notes (Andrew Toth)
b5696750a9 Test including coinbase transactions in receivedby wallet rpcs (Andrew Toth)
bce20c34d6 Include coinbase transactions in receivedby wallet rpcs (Andrew Toth)
Pull request description:
The current `*receivedby*` RPCs filter out coinbase transactions. This doesn't seem correct since an output to your address in a coinbase transaction *is* receiving those coins.
This PR corrects this behaviour. Also, a new option `include_immature_coinbase` is added (default=`false`) that includes immature coinbase transactions when set to true.
However, since this is potentially a breaking change this PR introduces a hidden configuration option `-deprecatedrpc=exclude_coinbase`. This can be set to revert to previous behaviour. If no reports of broken workflow are received, then this option can be removed in a future release.
Fixes https://github.com/bitcoin/bitcoin/issues/14654.

2ee406ce3e test: add functional test for deprecatedrpc=fees (josibake)
35d928c632 rpc: deprecate fee fields from mempool entries (josibake)
Pull request description:
per #22682 , top level fee fields for mempool entries have been deprecated since 0.17 but are still returned. this PR properly deprecates them so that they are no longer returned unless `-deprecatedrpc=fees` is passed.
the first commit takes care of deprecation and also updates `test/functional/mempool_packages.py` to only use the `fees` object. the second commit adds a new functional test for `-deprecatedrpc=fees`
closes#22682
## questions for the reviewer
* `-deprecatedrpc=fees` made the most sense to me, but happy to change if there is a name that makes more sense
* #22682 seems to indicate that after some period of time, the fields will be removed all together. if we have a rough idea of when this will be, i can add a `TODO: fully remove in vXX` comment to `entryToJSON`
## testing
to get started on testing, compile, run the tests, and start your node with the deprecated rpcs flag:
```bash
./src/bitcoind -daemon -deprecatedrpc=fees
```
you should see entries with the deprecated fields like so:
```json
{
"<txid>": {
"fees": {
"base": 0.00000671,
"modified": 0.00000671,
"ancestor": 0.00000671,
"descendant": 0.00000671
},
"fee": 0.00000671,
"modifiedfee": 0.00000671,
"descendantfees": 671,
"ancestorfees": 671,
"vsize": 144,
"weight": 573,
...
},
```
you can also check `getmempoolentry` using any of the txid's from the output above.
next start the node without the deprecated flag, repeat the commands from above and verify that the deprecated fields are no longer present at the top level, but present in the "fees" object

1ed5681407 rpc: add missing scantxoutset examples (Sebastian Falbesoner)
Pull request description:
The scantxoutset RPC and its help text was at last improved in #16285, but it's still missing examples (see https://github.com/bitcoin/bitcoin/pull/16285#issuecomment-529313781).
~Note that the example descriptor used doesn't follow the developer guideline of using invalid bech32 addresses, as the RPC is not wallet-related and it's use-case is merely to look up state information (i.e. there is no danger of sending funds to a wrong address).~ For the sake of simplicity, the raw descriptor for an early coinbase payout address (block 9) is taken, i.e. it yields results even at an early stage of IBD. Happy to change that though if there are other suggestions.

11daf6ceb1 More Span simplifications (Pieter Wuille)
568dd2f839 Replace MakeSpan helper with Span deduction guide (Pieter Wuille)
Pull request description:
C++17 supports [user-defined deduction guides](https://en.cppreference.com/w/cpp/language/class_template_argument_deduction), allowing class constructors to be invoked without specifying class template arguments. Instead, the code can contain rules to infer the template arguments from the constructor argument types.
This alleviates the need for the `MakeSpan` helper. Convert the existing MakeSpan rules into deduction rules for `Span` itself, and replace all invocations of `MakeSpan` with just `Span` ones.

Pull request description:
It seems confusing to call `GetAdjustedTime` there, because no offset could have been retrieved from the network at this point. Even if connman was started, `timedata` needs at least 5 peer connections to calculate an offset.
Fix the confusion by replacing `GetAdjustedTime` with `GetTime`, which does not change behavior.
Also:
* Replace magic number with `MAX_FUTURE_BLOCK_TIME` to clarify the context
* Add test, which passes both on current master and this pull request

a99ed89865 psbt: sign without finalizing (Andrew Chow)
Pull request description:
It can be useful to sign an input with `walletprocesspsbt` but not finalize that input if it is complete. This PR adds another option to `walletprocesspsbt` to be able to do that. We will still finalize by default.
This does not materially change the PSBT workflow since `finalizepsbt` needs to be called in order to extract the tx for broadcast.

As node operators are free to set their mempool policies however they
please, it's possible for package transaction(s) to already be in the
mempool. We definitely don't want to reject the entire package in that
case (as that could be a censorship vector).
We should still return the successful result to the caller, so add
another result type to MempoolAcceptResult.

Pull request description:
Similarly to how #18698 added `ProcessNewBlock()` and `ProcessNewBlockHeaders()` methods to the `ChainstateManager` class, this PR adds a new `ProcessTransaction()` method. Code outside validation no longer calls `AcceptToMemoryPool()` directly, but calls through the higher-level `ProcessTransaction()` method. Advantages:
- The interface is simplified. Calling code no longer needs to know about the active chainstate or mempool object, since `AcceptToMemoryPool()` can only ever be called for the active chainstate, and that chainstate knows which mempool it's using. We can also remove the `bypass_limits` argument, since that can only be used internally in validation.
- responsibility for calling `CTxMemPool::check()` is removed from the callers, and run automatically by `ChainstateManager` every time `ProcessTransaction()` is called.

to no longer use deprecated fields.

This is not only cleaner but also helps make sure we are always using
the virtual size measure that includes the sigop weight heuristic (which
is the vsize the mempool would return).

Author of #21245 expressed [time issues](https://github.com/bitcoin/bitcoin/pull/21245#issuecomment-902332088) in the original PR. Given that #21245 has received a lot of review*, I have decided to open this new pull request with [modifications required to get ACK from luke-jr ](https://github.com/bitcoin/bitcoin/pull/21245#issuecomment-905150806) and a few nits of mine.
### Original PR description
> Display the prevout in transaction inputs when calling getblock level 3 verbosity. This PR affects the existing `/rest/block` API by adding a `prevout` fields to tx inputs. This is mentioned in the change to the release notes.
>
> I added some functional tests that
>
> * checks that the RPC call still works when TxUndo can't be found
>
> * Doesn't display the "value" or "scriptPubKey" of the previous output when at a lower verbosity level
>
>
> This "completes" the issue #18771

There is no change in behavior. This just helps prepare for the
transition from boost::filesystem to std::filesystem by avoiding calls
to methods which will be unsafe after the transaction to std::filesystem
to due lack of a boost::filesystem::path::imbue equivalent and inability
to set a predictable locale.

4747da3a5b Add syscall sandboxing (seccomp-bpf) (practicalswift)
Pull request description:
Add experimental syscall sandboxing using seccomp-bpf (Linux secure computing mode).
Enable filtering of system calls using seccomp-bpf: allow only explicitly allowlisted (expected) syscalls to be called.
The syscall sandboxing implemented in this PR is an experimental feature currently available only under Linux x86-64.
To enable the experimental syscall sandbox the `-sandbox=<mode>` option must be passed to `bitcoind`:
```
-sandbox=<mode>
Use the experimental syscall sandbox in the specified mode
(-sandbox=log-and-abort or -sandbox=abort). Allow only expected
syscalls to be used by bitcoind. Note that this is an
experimental new feature that may cause bitcoind to exit or crash
unexpectedly: use with caution. In the "log-and-abort" mode the
invocation of an unexpected syscall results in a debug handler
being invoked which will log the incident and terminate the
program (without executing the unexpected syscall). In the
"abort" mode the invocation of an unexpected syscall results in
the entire process being killed immediately by the kernel without
executing the unexpected syscall.
```
The allowed syscalls are defined on a per thread basis.
I've used this feature since summer 2020 and I find it to be a helpful testing/debugging addition which makes it much easier to reason about the actual capabilities required of each type of thread in Bitcoin Core.

[About seccomp and seccomp-bpf](https://en.wikipedia.org/wiki/Seccomp):
> In computer security, seccomp (short for secure computing mode) is a facility in the Linux kernel. seccomp allows a process to make a one-way transition into a "secure" state where it cannot make any system calls except exit(), sigreturn(), and read() and write() to already-open file descriptors. Should it attempt any other system calls, the kernel will terminate the process with SIGKILL or SIGSYS. In this sense, it does not virtualize the system's resources but isolates the process from them entirely.
>
> […]
>
> seccomp-bpf is an extension to seccomp that allows filtering of system calls using a configurable policy implemented using Berkeley Packet Filter rules. It is used by OpenSSH and vsftpd as well as the Google Chrome/Chromium web browsers on Chrome OS and Linux. (In this regard seccomp-bpf achieves similar functionality, but with more flexibility and higher performance, to the older systrace—which seems to be no longer supported for Linux.)

ea31caf6b4 update estimatesmartfee rpc to return max of estimateSmartFee, mempoolMinFee and minRelayTxFee. (pranabp-bit)
Pull request description:
This PR is in response to the issue [#19699](https://github.com/bitcoin/bitcoin/issues/19699).
Based on the discussion in the comments of PR [#22673](https://github.com/bitcoin/bitcoin/pull/22673) changes have been made in the `estimatesmartfee` itself such that it takes into account `mempoolMinFee` and `relayMinFee` . Hence it provides a fee estimate that is most likely to be paid by the user in an actual transaction, preventing issues such as [#16072](https://github.com/bitcoin/bitcoin/issues/16072).
The test file test/functional/feature_fee_estimation.py has also been updated to check this functionality.

This will provide better estimates which would be closer to fee paid in actual
transactions.
The test has also been changed such that when the node is restarted with a
high mempoolMinFee, the estimatesmartfee still returns a feeRate greater
than or equal to the mempoolMinFee, minRelayTxFee.(just like the feeRate of actual transactions)
cdaab90662 Add test for addrman consistency check on restart with asmap (Jon Atack)
869f136816 Add test for rpc addpeeraddress with "tried" argument (Jon Atack)
ef242f5213 Allow passing "tried" to rpc addpeeraddress to call CAddrMan::Good() (Jon Atack)
Pull request description:
This pull adds a `tried` argument to RPC addpeeraddress and a regression test for the recent addrman/asmap changes and issue.
PR #22697 introduced a reproducible bug in commit 181a1207 that fails addrman consistency checks and causes it to significantly lose peer entries when the `-asmap` configuration option is used.
The issue occurs upon bitcoind restart due to an initialization order change in `src/init.cpp` in that commit, whereby CAddrman asmap is set after deserializing `peers.dat`, rather than before.
Issue reported on the `#bitcoin-core-dev` IRC channel starting at https://www.erisian.com.au/bitcoin-core-dev/log-2021-08-23.html#l-263.
```
addrman lost 22813 new and 2 tried addresses due to collisions or invalid addresses
ADDRMAN CONSISTENCY CHECK FAILED!!! err=-17 bitcoind: ./addrman.h:707: void CAddrMan::Check() const: Assertion `false' failed. Aborted
```
How to reproduce:
- `git checkout 181a1207`, build, and launch bitcoind with the `-asmap` and `-checkaddrman=1` configuration options enabled
- restart bitcoind
- bitcoind aborts on the second call to the addrman consistency checks in `CAddrMan::Check()`
How to test this pull:
- `git checkout 181a1207`, cherry pick the first commit of this branch, build, git checkout this branch, run `test/functional/rpc_net.py`, which should pass, and then run `test/functional/feature_asmap.py`, which should fail with the following output:
```

Addresses and closes#22368
As per that issue (and its predecessor #14907), there seems to be some interest in allowing unspent outputs to be locked persistently. This PR does so by adding a flag to lockunspent to store the change in the wallet database. Defaults to false, so there is no change in default behaviour.
Edit: GUI commit changes default behaviour. UTXOs locked/unlocked via the GUI are now persistent.

ea98d9c2ef rpc: fix/add missing RPCExamples for "Util" RPCs (Sebastian Falbesoner)
Pull request description:
Similar to https://github.com/bitcoin/bitcoin/pull/18398, this PR gives the RPCExamples in the RPC category "Util" (that currently contains `createmultisig`, `deriveaddresses`, `estimatesmartfee`, `getdescriptorinfo`, `signmessagewithprivkey`, `validateaddress`, `verifymessage`) some love by fixing one broken and adding three missing examples:
- fixed `HelpExampleRpc` for `createmultisig` (disturbing escape characters and quotation marks)
- added missing `HelpExampleRpc` for
- `deriveaddresses` (also put descriptor in a new string constant)
- `estimatesmartfee`
- `getdescriptorinfo` (also put descriptor in a new string constant)

ae23faba6f Add a new RPC command: restorewallet (lsilva01)
Pull request description:
As far as I know, there is no command to restore the wallet from a backup file.
The only way to do this is to replace the `wallet.dat` of a newly created wallet with the backup file, which is hardly an intuitive way.
This PR implements the `restorewallet` RPC command which restores the wallet from the backup file.
To test:
First create a backup file:
`$ bitcoin-cli -rpcwallet="wallet-01" backupwallet /home/Backups/wallet-01.bak`
Then restore it in another wallet:
`$ bitcoin-cli restorewallet "restored-wallet-01" /home/Backups/wallet-01.bak`

Pull request description:
This PR implements a function to calculate mempool ancestors for a package and enforces ancestor/descendant limits on them as a whole. It reuses a portion of `CalculateMemPoolAncestors()`; there's also a small refactor to move the reused code into a generic helper function. Instead of calculating ancestors and descendants on every single transaction in the package and their ancestors, we use a "worst case" heuristic, treating every transaction in the package as each other's ancestor and descendant. This may overestimate everyone's counts, but is still pretty accurate in the our main package use cases, in which at least one of the transactions in the package is directly related to all the others (e.g. 1 parent + 1 child, multiple parents with 1 child, or chains).
Note on Terminology: While "package" is often used to describe groups of related transactions _within_ the mempool, here, I only use package to mean the group of not-in-mempool transactions we are currently validating.
#### Motivation
It would be a potential DoS vector to allow submission of packages to mempool without a proper guard for mempool ancestors/descendants. In general, the purpose of mempool ancestor/descendant limits is to limit the computational complexity of dealing with families during removals and additions. We want to be able to validate multiple transactions on top of the mempool, but also avoid these scenarios:
- We underestimate the ancestors/descendants during package validation and end up with extremely complex families in our mempool (potentially a DoS vector).
- We expend an unreasonable amount of resources calculating everyone's ancestors and descendants during package validation.

In a couple of places in the wallet, errors are `std::string`. In order for these errors to be translated, change them to use `bilingual_str`.

bb822a7af8 wallet, rpc: add listdescriptors private option (S3RK)
Pull request description:
Rationale: make it possible to backup your wallet with `listdescriptors` command
* The default behaviour is still to show public version
* For private version only the root xprv is returned
Example use-case:
```
> bitcoin-cli -regtest -named createwallet wallet_name=old descriptors=true
> bitcoin-cli -regtest -rpcwallet=old listdescriptors true | jq '.descriptors' > descriptors.txt
> bitcoin-cli -regtest -named createwallet wallet_name=new descriptors=true blank=true
> bitcoin-cli -regtest -rpcwallet=new importdescriptors "$(cat descriptors.txt)"
```
In case of watch-only wallet without private keys there will be following output:
```
error code: -4
error message:
Can't get descriptor string.
```
