06c5ce9714 Re-include RBF replacement txs in fee estimation (Antoine Poinsot)
Pull request description:
This effectively reverts #9519.
RBF is now largely in use on the network (signaled for by around 20% of
all transactions on average) and replacement logic is implemented in
most end-user wallets. The rate of replaced transactions is also
expected to rise as fee-bumping techniques are being developed for
pre-signed transaction ("L2") protocols.

```
The only added dependency is that `convert` from ImageMagick (or compatible fork) is installed.
Captchas are disabled by default for custom faucets, but it is possible to specify a custom captcha URL on the command line.
Also adds a way to change the amount requested with e.g. `-n 0.1`.
Edit: credit where credit is due, yope gave me the idea of using Braille characters as a widely available way to do graphics in the terminal. Another possibility is `2x2` block characters but it is a lot less compact. Yet another one is [VT340 Sixel graphics](https://en.wikipedia.org/wiki/Sixel) but it's not supported in many terminal emulators.

Introduce the pimpl pattern for AddrMan to separate the implementation details from the externally used object representation. This reduces compile-time dependencies and conceptually clarifies AddrMan's interface from the implementation specifics.
Since the unit & fuzz tests currently rely on accessing AddrMan internals, this PR introduces addrman_impl.h, which is exclusively imported by addrman.cpp and test files.

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.)

38f5642ccc allow fundtx rpcs to work with external inputs (Andrew Chow)
d5cfb864ae Allow Coin Selection be able to take external inputs (Andrew Chow)
a00eb388e8 Allow CInputCoin to also be constructed with COutPoint and CTxOut (Andrew Chow)
Pull request description:
Currently `fundrawtransaction` and `walletcreatefundedpsbt` both do not allow external inputs as the wallet does not have the information necessary to estimate their fees.
This PR adds an additional argument to both those RPCs which allows the user to specify solving data. This way, the wallet can use that solving data to estimate the size of those inputs. The solving data can be public keys, scripts, or descriptors.

Test the properties of transactions conflicted by a double
spend as returned by RPC listtransactions in the "abandoned",
"confirmations", "trusted" and "walletconflicts" fields.
These fields are also returned by RPCs listsinceblock and
gettransactions.
As the faucet will always ask for a captcha now, the current script is
no longer usable.
Change the script to print the captcha in dot-matrix to the terminal,
using unicode Braille characters.
Also:
* Remove redundant {} from return statement
* Add missing failing c-string test case and "-" and "+" strings
* Add missing failing test cases for non-int32_t integral types
b658d7d5c5 test: update assert_fee_amount() in test_framework/util.py (Jon Atack)
Pull request description:
Follow-up to 42e1b5d979 (#12486).
- update call to `round()` with our utility function `satoshi_round()` to avoid intermittent test failures
- rename `fee_per_kB` to `feerate_BTC_kvB` for precision
- store division result in `feerate_BTC_vB`
Possibly resolves#19418.

0ab4c3b272 Return false on corrupt tx rather than asserting (Samuel Dobson)
Pull request description:
Takes up #19793
Rather than asserting, we log an error and return CORRUPT so that the user is informed. This type of error isn't critical so it isn't worth `assert`ing.

Code review ACK 0ab4c3b272. There may be room for more improvements later like better error messages or easier recovery options, but changing from an assert to an error seems like a clear improvement, and this seems to avoid all the pitfalls of the last PR that tried this.

0dc8bf5b92 [net processing] Dont request compact blocks in blocks-only mode (Niklas Gögge)
Pull request description:
A blocks-only node does not participate in transaction relay to reduce its own bandwidth usage and therefore does not have a mempool. The use of compact blocks is not beneficial to such a node since it will always have to download full blocks.
In both high- and low-bandwidth relaying the `cmpctblock` message is sent. This represent a bandwidth overhead for blocks-only nodes because the `cmpctblock` message is several times larger in the average case than the equivalent `headers` or `inv` announcement.
![compact blocks](https://raw.githubusercontent.com/bitcoin/bips/master/bip-0152/protocol-flow.png)
>**Example:**
>A block with 2000 txs results in a `cmpctblock` with 2000*6 bytes in short ids. This is several times larger than the equivalent 82 bytes for a `headers` message or 37 bytes for an `inv`.
## Approach
This PR makes blocks-only nodes always use the legacy relaying to download new blocks.
It does so by making blocks-only nodes never initiate a high-bandwidth block relay connection by disabling the sending of `sendcmpct(1)`. Additionally a blocks-only node will never request a compact block using `getdata(CMPCT)`.
A blocks-only node will continue to serve compact blocks to its peers in both high- and low-bandwidth mode.
