Compiling C++ code with `-D_XOPEN_SOURCE=600` causes problems on
OpenBSD. If that define is set, the C++ standard header detection
routine in BDB's configure script fails. This results in
`HAVE_CXX_STDHEADERS` not being defined, which then it turn leads to
the inclusion of `<iostream.h>` (rather than `<iostream>`), which
doesn't exist.
According to a mailing list post discussing a similar problem [1],
"OpenBSD provides the POSIX APIs by default", so we don't need this
define anyway and can remove it. This fixes the BDB build problem as
described in issue #28963.
Tested on OpenBSD 7.4 with clang 13.0.0.

An alternative to https://github.com/bitcoin/bitcoin/pull/29232
Rather than switching to the CMake builds which [proved problematic](https://github.com/bitcoin/bitcoin/pull/29232#issuecomment-1898513919), do the quick and dirty thing of just patching out libtool. Doesn't seem to introduce any new issues.
This should buy us time to upstream the necessary CMake fixes.

The `--enable-debug` configure option for the SQLite package does two
things. It adds three preprocessor definitions and overrides CFLAGS with
"-g -O0". The latter breaks the user's ability to provide sanitizer and
LTO flags.
On some systems, libmultiprocess would be installed into `lib64`, I
assume due to the use of GNUInstallDirs, however all other libs we build
in depends, go into lib/. Rather than adding lib64/ to the pkg-config
and link flags, I opted for always installing into lib/.
This was changed in
https://github.com/chaincodelabs/libmultiprocess/pull/79 upstream.

05aca09381 build: Patch Qt to handle minimum macOS version properly (Hennadii Stepanov)
Pull request description:
This PR is:
- required to [switch](https://github.com/bitcoin/bitcoin/pull/28622) to macOS 14 SDK (Xcode 15).
- an alternative to https://github.com/bitcoin/bitcoin/pull/28732 and https://github.com/bitcoin/bitcoin/pull/28775.
Qt relies on the `__MAC_OS_X_VERSION_MIN_REQUIRED` macro, which is set in the `AvailabilityInternal.h` SDK header to
the value provided by the Clang driver from the `-mmacos-version-min` / `-mmacosx-version-min` option.
Xcode 12 SDK expects the OS-specific `__ENVIRONMENT_MAC_OS_X_VERSION_MIN_REQUIRED__` macro:
```c++
#ifndef __MAC_OS_X_VERSION_MIN_REQUIRED
#ifdef __ENVIRONMENT_MAC_OS_X_VERSION_MIN_REQUIRED__
/* compiler for Mac OS X sets __ENVIRONMENT_MAC_OS_X_VERSION_MIN_REQUIRED__ */
#define __MAC_OS_X_VERSION_MIN_REQUIRED __ENVIRONMENT_MAC_OS_X_VERSION_MIN_REQUIRED__
#endif
#endif /* __MAC_OS_X_VERSION_MIN_REQUIRED*/
```
In the other hand, Xcode 15 SDK expects a general `__ENVIRONMENT_OS_VERSION_MIN_REQUIRED__` macro:
```c++
#ifndef __MAC_OS_X_VERSION_MIN_REQUIRED
#if defined(__has_builtin) && __has_builtin(__is_target_os)
#if __is_target_os(macos)
#define __MAC_OS_X_VERSION_MIN_REQUIRED __ENVIRONMENT_OS_VERSION_MIN_REQUIRED__
#define __MAC_OS_X_VERSION_MAX_ALLOWED __MAC_14_0
#endif
#elif __ENVIRONMENT_MAC_OS_X_VERSION_MIN_REQUIRED__
#define __MAC_OS_X_VERSION_MIN_REQUIRED __ENVIRONMENT_MAC_OS_X_VERSION_MIN_REQUIRED__
#define __MAC_OS_X_VERSION_MAX_ALLOWED __MAC_14_0
#endif /* __has_builtin(__is_target_os) && __is_target_os(macos) */
#endif /* __MAC_OS_X_VERSION_MIN_REQUIRED */
```
The latter macro is not provided by LLVM Clang until c8e2dd8c6f, which is available in Clang 17.
The suggested patch makes Qt "borrow" the `__MAC_OS_X_VERSION_MIN_REQUIRED` value from `MAC_OS_X_VERSION_MIN_REQUIRED`, which is set in the `AvailabilityMacros.h` SDK header.

3333f14efa depends: Bump to capnproto-c++-1.0.1 (MarcoFalke)
Pull request description:
Reasons:
* Debian is starting to ship this version in Trixie (https://packages.debian.org/trixie/capnproto), which will likely become the version shipped with Ubuntu 24.04 LTS. So testing with this version will help to find any issues before real users start to use those distro packages.
* The feature is currently experimental, so bumping the version shouldn't cause any production issues.
* With multiprocess begin a priority project for 27.0, it seems better to do build system changes/bumps early, rather than later, to allow for more time testing them.

Patch in suport for using -no_fixup_chains, with ld64. This option just
seems to be missing from our version, as it exists in later releases.
This is needed so we can disable fixup_chains in our security checks.
Unfortunately clang 10 does not understand "-mmacosx-version-min=11.0",
as it expects to see only 10.x.
Bump minimally to 11.1 to fix that problem. This will likely be our last
binary toolchain bump, as it will soon be replaced with usage of upstream
vanilla llvm.
This will allow us to use the existing machinery for filtering by
arch, os, debug/release, etc.
For example, the following becomes possible for libevent:
$(package)_config_opts_release=-DEVENT__DISABLE_DEBUG_MODE
Now the define is only set when not building depends with DEBUG=1

Add an option that when passed, will disable hardening options, and
pass `--disable-hardening` through to configure. Due to the way
we link libssp for Windows builds, they now fail (after #27118),
if building with depends, and configuring with --disable-hardening.
See:
https://github.com/bitcoin/bitcoin/pull/27118#issuecomment-1492606272.
This change would add a depends opiton such that, if someone wants to
build with, for windows, without hardening, they can do so. This may
also be useful when building for debugging.
Use the same workaround we've applied to qrencode, and other packages.
Fontconfig not building is currently a blocker for fuzz/sanitizer infra
upgrades.
For now, this is also more straightforward than bumping the package,
which introduces more complexity/usage of gperf.
