32e2ffc393 Remove the syscall sandbox (fanquake)
Pull request description:
After initially being merged in #20487, it's no-longer clear that an internal syscall sandboxing mechanism is something that Bitcoin Core should have/maintain, especially when compared to better maintained/supported alterantives, i.e [firejail](https://github.com/netblue30/firejail).
There is more related discussion in #24771.
Note that given where it's used, the sandbox also gets dragged into the kernel.
If it's removed, this should not require any sort of deprecation, as this was only ever an opt-in, experimental feature.
Closes#24771.

cbee1d7091 depends: modernize clang flags (Cory Fields)
2a85857ce5 ci: disable false-positive warnings for now (Cory Fields)
Pull request description:
This is a cleaner and simpler alternative to #25098. Inspired by [this conversation](https://github.com/bitcoin/bitcoin/pull/27737#issuecomment-1562543301). The diff is large but the change itself is quite small.
Fixes builds with llvm >= 11 in guix by working around the problem. As a bonus, this is much cleaner and more maintainable than what we had before.
See the updated comment for more info. At a high level: rather than playing tricks and trying to work around clang's default includes, disable them and re-add what we want.

ACK cbee1d7091 - tested Guix and the depends cross-compile. Would like to move this along, to unblock #27676, which itself might be a blocker for #27897. Note that macOS might seem somewhat in flux for the moment, but once we finish the migration to LLVM Clang + LLD, things will be must simpler, and ultimately more maintainable.

clang <=17 warns on -nostdlibinc, which causes an error on our -Werror builds.
Note that this breaks the "-fPIE" check in configure because it relies on
catching warnings, but that is not a problem for macOS.

Pull request description:
This reworks the MSAN CIs, to first compile Clang and compiler-rt (using GCC 12), and then, compile an MSAN instrumented libc++ using the just-built Clang 16. This fixes the `native_fuzz_with_msan` job, working around https://bugs.debian.org/cgi-bin/bugreport.cgi?bug=1005341, by not using the Debian provided Clang/LLVM.
Also included are changes to streamline how we use our "custom libc++", according to upstream: https://releases.llvm.org/16.0.0/projects/libcxx/docs/UsingLibcxx.html#using-a-custom-built-libc, as well as other minor cleanups in the CI configs.
An example job is currently running in the qa-assets repo: https://github.com/bitcoin-core/qa-assets/pull/129 (https://cirrus-ci.com/task/4632561431871488).

59c8944749 build: disable boost multi index safe mode (willcl-ark)
Pull request description:
Fixes#27586
Disable boost multi index safe mode by default when configuring with
--enable-debug.
This option can cause transactions to take a long time to be accepted
into the mempool under certain conditions; iterator destruction takes
O(n) time vs O(1) as they are stored in a singly linked list. See
27586 and the [boost docs](https://www.boost.org/doc/libs/1_58_0/boost/multi_index/detail/safe_mode.hpp) for more information.
Re-enable it on the CI builds which previously had it enabled.
Re-enable it on the msan fuzz task so that we have fuzz tasks testing
with it enabled and disabled in this repo.

c13c97dbf8 random: getentropy on macOS does not need unistd.h (fanquake)
Pull request description:
This requires a linux kernel of `3.17`+, which seems entirely
reasonable. `3.17` went EOL in 2015, and the last supported `3.x` kernel
(`3.16`) went EOL > 4 years ago, in 2020. For reference, the current
oldest maintained kernel is `4.14` (released 2017, going EOL Jan 2024).
Support for `getrandom()` (and `getentropy()`) was added to
glibc `2.25` https://sourceware.org/legacy-ml/libc-alpha/2017-02/msg00079.html:
> * The getentropy and getrandom functions, and the <sys/random.h> header
file have been added.
and we already require `2.27` or later.
All that being said, I don't think you would encounter a current day (+~6 months from now)
system, running with kernel headers older than 3.17 (released 2014) but also having a
glibc of 2.27+ (released 2018)?
Removing this (our only) use of `syscall()` also means we can drop a workaround in our MSAN jobs.
If this is merged, I'll drop the [same workaround in oss-fuzz](25946a5448/projects/bitcoin-core/build.sh (L49-L56)).

We no-longer run any security/syymbol checks in the CI, and doubt we

redundant in any case). The CI environment doesn't (exactly) match the

This partially reverts commit 71383f2fad.
This should be fine, because if warnings are issues again in the future,
it can be disabled again, along with a list of the false warnings.
