Having the link check in the header check loop means we get `-lminiupnpc
-lminiupnpc -lminiupnpc` on the link line. This is unnecessary, and
results in warnings, i.e:
```bash
ld: warning: ignoring duplicate libraries: '-levent', '-lminiupnpc'
ld: warning: ignoring duplicate libraries: '-levent', '-lminiupnpc'
ld: warning: ignoring duplicate libraries: '-levent', '-lminiupnpc'
```
These warnings have been occurring since the new linker released with
Xcode 15, and also came up in https://github.com/hebasto/bitcoin/pull/34.

faf70c1f33 Bump python minimum version to 3.9 (MarcoFalke)
fa8996b930 ci: Bump i686_multiprocess.sh to latest Ubuntu LTS (MarcoFalke)
Pull request description:
All supported operating systems ship with python 3.9 (or later), so bumping the minimum should not cause any issues. A bump will allow new code to use new python 3.9 features.
For reference:
* https://packages.debian.org/bullseye/python3
* https://packages.ubuntu.com/focal/python3.9
* FreeBSD 12/13 also ships with 3.9
* CentOS-like 8/9 also ships with 3.9 (and 3.11)
* OpenSuse Leap also ships with 3.9 (and 3.11) https://software.opensuse.org/package/python311-base
This is for Bitcoin Core 27.0 in 2024 (next year), not the soon upcoming 26.0 next month.

This is not a hardening specific flag, it should be used at all times,
regardless of if hardening is enabled or not. Note that this was
still the case here, but having this exist in the hardening flags is
confusing, and may lead someone to move it inside one of the `use_hardening`
blocks, where it would become unused, with `--disable-hardening`.
This is a simpler (less hardening) version of #24123.
Scoped to aarch64 to avoid unused command line option warnings when
building on x86_64.
Related to #19075.
We currently work around a longstanding GCC issue with aligned vector
instructions, in our release builds, by patching the behaviour we want
into GCC (see discussion in #24736).
A new option now exists in the binutils assembler,
`-muse-unaligned-vector-move`, which should also achieve the behaviour
we want (at least for our code). This was added in the 2.38 release,
see
https://sourceware.org/git/?p=binutils-gdb.git;a=commit;h=c8480b58e1968f209b6365af7422678f348222c2.
```bash
x86: Add -muse-unaligned-vector-move to assembler
Unaligned load/store instructions on aligned memory or register are as
fast as aligned load/store instructions on modern Intel processors. Add
a command-line option, -muse-unaligned-vector-move, to x86 assembler to
encode encode aligned vector load/store instructions as unaligned
vector load/store instructions.
```
Even if we introduce this option into our build system, we'll have to
maintain our GCC patching, as we want all code that ends up in the
binary, to avoid these instructions. However, there may be some value in
adding the option, as it could be an improvement for someone building
(bitcoind.exe) with an unpatched compiler.
08eb5f1b67 ci: document that -Wreturn-type has been fixed upstream (Windows) (fanquake)
Pull request description:
`noreturn` attributes have been added to the mingw-w64 headers, 1690994f51, meaning that [from 11.0.0 onwards](https://www.mingw-w64.org/changelog/), you'll no-longer see `-Wreturn-type` warnings when using `assert(false)`.
Add -Wno-return-type to the Windows CI, where is should have been all
along, and document why it's required. This can be dropped when we are
using the fixed version of the mingw-w64 headers there.
Drop the -Werror -Wno-return-type special case from our build system.
-Wreturn-type is on by default in Clang and GCC.
The new mingw-w64 header behaviour can be checked on Ubuntu mantic, [which ships with 11.0.0](https://packages.ubuntu.com/mantic/mingw-w64), using:
```cpp
#include <cassert>
int f(){ assert(false); }
int main() {
return 0;
}
```
On Mantic (with 11.0.0):
```bash
x86_64-w64-mingw32-g++ test.cpp -Wreturn-type
# nada
```
On Lunar ([with 10.0.0](https://packages.ubuntu.com/lunar/mingw-w64)):
```bash

8f6f0d81ee guix: backport glibc patch to prevent redundant librt link (fanquake)
e14473299c contrib: remove librt from release deps (fanquake)
e64e17830a build: remove check for gettimeofday & librt (fanquake)
Pull request description:
Our release binaries currently have a runtime dependency on `librt`. However this is redundant, and only the case due to a bug in glibc. The `clock_*` suit of funcs were absorbed into libc long ago, however an issue with compatibility code meant that librt would still be linked against / used redundantly:
> But the forwarders were not marked as compatibility symbols.
> As a result, on older architectures, historic configure checks such as
> AC_CHECK_LIB(rt, clock_gettime)
> still cause linking against librt, even though this is completely
> unnecessary. It also creates a needless porting hazard because
> architectures behave differently when it comes to symbol availability.
This PR drops our configure check for librt (which is redundant, and could be PR'd standalone), and backports [the relevant patch](https://sourceware.org/git/?p=glibc.git;a=commit;h=f289e656ec8221756519a601042bc9fbe1b310fb) into our glibc, so we can drop librt from our runtime dependencies.

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.

This replaces (but does not collide with) the previous bind_on_load. There
is technically no need to opt-in to this functionality as long as >= MacOS 11.0

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 for more information.
Re-enable it on the CI builds which previously had it enabled.
Re-enable it on the msan fuzz target so that we have fuzz tasks testing
with it enabeld and disabled in this repo.

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)).

fa5831bd6f build: Do not define `ENABLE_ZMQ` when ZMQ is not available (Hennadii Stepanov)
Pull request description:
A new behavior is consistent with the other optional dependencies.
The source code contains `#if ENABLE_ZMQ` lines only:
```
$ git grep ENABLE_ZMQ -- src/*.cpp
src/init.cpp:#if ENABLE_ZMQ
src/init.cpp:#if ENABLE_ZMQ
src/init.cpp:#if ENABLE_ZMQ
src/init.cpp:#if ENABLE_ZMQ
src/init.cpp:#if ENABLE_ZMQ
```
Change in description line -- "Define to 1..." --> "Define this symbol.." -- is motivated by the fact that the actual value of the defined `ENABLE_ZMQ` macro does not matter at all.

libtool gets a false-positive from the warning produced by lld -single_module
because it is already the default and unneeded.
Skip the check unconditionally for Darwin linkers.
glibc 2.33 introduced a new fortification level, _FORTIFY_SOURCE=3.
Which improves the coverage of cases where _FORTIFY_SOURCE can use _chk
functions. For example, using GCC 13 and glibc 2.36 (Fedora Rawhide),
compiling master:
```bash
nm -C src/bitcoind | grep _chk
U __fprintf_chk@GLIBC_2.17
U __memcpy_chk@GLIBC_2.17
U __snprintf_chk@GLIBC_2.17
U __sprintf_chk@GLIBC_2.17
U __stack_chk_fail@GLIBC_2.17
U __stack_chk_guard@GLIBC_2.17
U __vsnprintf_chk@GLIBC_2.17
objdump -d src/bitcoind | grep "_chk@plt" | wc -l
33
```
vs this branch:
```bash
nm -C src/bitcoind | grep _chk
U __fprintf_chk@GLIBC_2.17
U __memcpy_chk@GLIBC_2.17
U __memset_chk@GLIBC_2.17
U __snprintf_chk@GLIBC_2.17
U __sprintf_chk@GLIBC_2.17
U __stack_chk_fail@GLIBC_2.17
U __stack_chk_guard@GLIBC_2.17
U __vsnprintf_chk@GLIBC_2.17
objdump -d src/bitcoind | grep "_chk@plt" | wc -l
61
```
Usage of level 3 requires LLVM/Clang 9+, or GCC 12+. Older
compilers/glibc will still use _FORTIFY_SOURCE=2. For example, in the
glibc we currently use for Linux release builds (2.24), FORTIFY_LEVEL is
determined using the following:
```c
```
so any value > 1 will turn on _FORTIFY_SOURCE=2.

Even though all other targets are disabled, we still need Boost CPPFLAGS
(use_boost) to compile. This currently works everywhere, except on arm
macOS (where the include path is pretty non-standard), because
generally, the Boost include path is generic, i.e `/usr/include`.
d4c59da8d6 build: Avoid `BOOST_NO_CXX98_FUNCTION_BASE` macro redefinition (Hennadii Stepanov)
Pull request description:
With GCC 12 and Boost 1.81 (from depends) having multiple warnings:
```
In file included from /home/hebasto/bitcoin/depends/x86_64-pc-linux-gnu/include/boost/config.hpp:48:
/home/hebasto/bitcoin/depends/x86_64-pc-linux-gnu/include/boost/config/stdlib/libstdcpp3.hpp:397:9: warning: 'BOOST_NO_CXX98_FUNCTION_BASE' macro redefined [-Wmacro-redefined]
#define BOOST_NO_CXX98_FUNCTION_BASE
^
<command line>:8:9: note: previous definition is here
#define BOOST_NO_CXX98_FUNCTION_BASE 1
^
1 warning generated.
```
This PR fixes those warnings.
Defining of the `BOOST_NO_CXX98_FUNCTION_BASE` macro was introduced in https://github.com/bitcoin/bitcoin/pull/25436, but since https://github.com/boostorg/config/pull/430, it is required to check it before adding.

Pull request description:
This PR removes the `--enable-upnp-default` and `--enable-natpmp-default` options from configure.
It's odd to me that we maintain configure-time options for setting the default port-forwarding runtime state (but no other similar options), and I'm not sure what use-case it satisfies, that can't be achieved by multiple other means. I also doubt that we'll ever restart using these in release builds, or turning on any of this by default.
I think the only scenario these options would be used is when you want to compile your own binaries (we don't use them in Guix), with port-forwarding on by default, but otherwise can't or don't want to use a `.conf` file, can't or don't want to pass command line options at runtime, and also don't want to modify the source code?
