7e88f61b28 multiprocess: Make interfaces::Chain::isTaprootActive non-const (Russell Yanofsky)
Pull request description:
`interfaces::Chain` is an abstract class, so declaring the method const would be exposing internal implementation details of subclasses to interface callers. And specifically this doesn't work because the multiprocess implementation of the `interfaces::Chain::isTaprootActive` method can't be const because IPC connection state and request state is not constant during the call.

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 WalletControllerActivity progress dialog had title of "Bitcoin-Qt".
The window title for opening wallet window should be "Open Wallet",
for creating wallet window should be "Create Wallet", and for the window
that is displayed when wallets are being loaded at startup should be
"Load Wallets". This PR fixes that.
Put these in `#ifdef` as they are newer syscalls that might not be
defined on all kernels:
__NR_pkey_alloc
__NR_pkey_free
__NR_pkey_mprotect
__NR_preadv2
__NR_pwritev2
Thanks to jamesob for reporting.
Use a (reference) parameter instead of a data member of
CAddrManDeterministic. This will allow us to make Fill() a free function
in a later commit.
Also remove CAddrManDeterministic.m_fuzzed_data_provider since it's no
longer used.

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.)
