fae20e6b50 Revert "Avoid the use of P0083R3 std::set::merge" (MarcoFalke)
fab53b5fd4 ci/doc: Set minimum required clang/libc++ version to 8.0 (MarcoFalke)
Pull request description:
This is not for 23.0, but for 24.0. It comes with the following benefits:
* Can use C++17 P0083R3 std::set::merge from libc++ 8.0
* No longer need to provide support for clang-7, which already fails to compile on some architectures (https://github.com/bitcoin/bitcoin/issues/21294#issuecomment-998098483)
This should be fine, given that all supported operating systems ship with at least clang-10:
* CentOS 8: clang-12
* Stretch: https://packages.debian.org/stretch/clang-11
* Buster: https://packages.debian.org/buster-backports/clang-11
* Bionic: https://packages.ubuntu.com/bionic-updates/clang-10
* Focal: https://packages.ubuntu.com/focal/clang-10

ACK fae20e6b50 - I think this is fine to do. I would be surprised if in another 6 months time someone was stuck on a system we supported, needing to compile Core, and only had access to Clang 7 or older. As mentioned in the PR description, all systems we currently support, already support multiple newer versions of Clang.

ACK fae20e6b50, I have reviewed the code and it looks OK, I agree it can be merged.

This primarily improves support for external signing, as it includes
multiple bugfixes for Boost Process. As well as various improvements to
the multi-index library.
6200fbf54f build: rename --enable-ebpf to --enable-usdt (0xb10c)
e158a2a7aa build: add systemtap's sys/sdt.h as depends (0xb10c)
Pull request description:
There has been light conceptual agreement on including the Userspace, Statically Defined Tracing tracepoints in Bitcoin Core release builds. This, for example, enables user to hook into production deployments, if they need to. Binaries don't have to be switched out. This is possible because we don't do [expensive computations](https://github.com/bitcoin/bitcoin/blob/master/doc/tracing.md#no-expensive-computations-for-tracepoints) only needed for the tracepoints. The tracepoints are NOPs when not used.
Systemtap's `sys/sdt.h` header is required to build Bitcoin Core with USDT support. The header file defines the `DTRACE_PROBE` macros used in [`src/util/trace.h`](https://github.com/bitcoin/bitcoin/blob/master/src/util/trace.h). This PR adds Systemtap 4.5 (May 2021) as dependency. GUIX builds for Linux hosts now include the tracepoints.
Closes https://github.com/bitcoin/bitcoin/issues/23297.

ACK 6200fbf54f - tested enabling / disabling and with/without SDT from depends. We can follow up with #23819, #23907 and #23296, and if any serious issues arise before feature freeze, it is easy for us to flip depends such that USDT becomes opt-in, rather than opt-out, and thus, releases would be tracepoint free.

The sys/sdt.h header is required to build Bitcoin Core with Userspace
Statically Defined Tracing support. Systemtap version 4.5 (May 2021)
is used as the most recent version 4.6 (Nov 2021) fails to build.
See e.g. https://sourceware.org/git/?p=systemtap.git;a=commit;h=1d3653936fc1fd13135a723a27e6c7e959793ad0
As Systemtap itself is not needed, the build steps (configure and
make) are skipped. We require fewer build dependecies and don't
waste time building depends we don't end up using. However, the
configure step would normally processes sys/sdt-config.h.in. The
resulting sdt-config.h defines _SDT_ASM_SECTION_AUTOGROUP_SUPPORT
(either 0 or 1 to indicate whether the assembler supports "?" in
.pushsection directives). For now, we assume all currently used
assemblers supports this feature and remove the check from the
sys/sdt.h header file in a patch.

From what I can see the only platform this drops support for is CentOS
7. CentOS 7 reached the end of it's "full update" support at the end of
2020. It does receive maintenance updates until 2024, however I don't
think supporting glibc 2.17 until 2024 is realistic. Note that anyone
wanting to self-compile and target a glibc 2.17 runtime could build with
--disable-threadlocal.
glibc 2.18 was released in August 2013.

Pull request description:
Adds a `--without-bdb` option to `configure` which disables the compilation of the BDB stuff. Legacy wallets will not be created when BDB is not compiled. A legacy-sqlite wallet can be loaded, but we will not create them.
Based on #20156 to resolve the situation where both `--without-sqlite` and `--without-bdb` are provided. In that case, the wallet is disabled and `--disable-wallet` is effectively set.
