a4118c6e20 Add patch to make codesign_allocate compatible with Apple's (Pieter Wuille)
Pull request description:
This is an alternative to #20638.
The problem is that Apple's codesign(_allocate) apparently rounds the "vmsize" attribute on the __LINKEDIT section to a multiple of 0x2000 on x86_64 rather than 0x1000 (as their published source code does). This divergence means that the binary signed by codesign is slightly different from the one recreated by our reattach-sig-to-gitian-output process, and the signature being invalid.
This fixes it by patching our codesign_allocate source code to also use 0x2000. In tests, this appears to result in matching binaries.

7d0271b5c3 depends: Set CMAKE_INSTALL_RPATH for native packages (Russell Yanofsky)
Pull request description:
This PR is part of the [process separation project](https://github.com/bitcoin/bitcoin/projects/10).
---
After #19685 started setting `LDFLAGS`, the `INSTALL_RPATH_USE_LINK_PATH` cmake option used in the libmultiprocess build no longer works, so it is neccessary to set `CMAKE_INSTALL_RPATH` as a fallback.
It's unclear currently whether the bad interaction between `INSTALL_RPATH_USE_LINK_PATH` and `LDFLAGS` is a bug, but the issue is reported:

Pull request description:
This consolidates our macOS build code so that `.DS_Store` generation is the same when running `make deploy` for macOS when building on Linux and macOS, rather than maintaining two version of code that essentially do the same thing (just slightly differently).
It also removes unused code and any AppleScript usage, automates finding translation files and generally simplifies `macdeployqtplus`. It also gets rid of the annoying "popping up" behaviour during DMG generation, names the created image `Bitcoin-Core.dmg` rather than `Bitcoin-Qt.dmg`.

Pull request description:
In packages where we are passing `-std=c++11` switch to `-std=c++17`, or, `-std=c++1z` in the case of Qt.
This PR also contains a [commit](104e859c97) that improves debug output when building Qt for debugging (`DEBUG=1`).
Now we'll get output like this:
```bash
g++ -c -pipe -ffunction-sections -O2 -fPIC -std=c++11 -fno-exceptions <lots more> ../../corelib/kernel/qcoreapplication.cpp
```
rather than just:
```bash
compiling ../../corelib/kernel/qcoreapplication.cpp
```
Note that when you look at the DEBUG output for these changes when building Qt, you'll see objects being compiled with a mix of C++11 and C++17. The breakdown is roughly:
1. `qmake` built with `-std=c++11`:
```bash
Creating qmake...
make[1]: Entering directory '<trim>/qt/5.9.8-4110fa99945/qtbase/qmake'
g++ -c -o project.o -std=c++11 -ffunction-sections -O2 -g <trim> <trim>/qt/5.9.8-4110fa99945/qtbase/qmake/project.cpp
# when qmake, Qt also builds some of it's corelib, such as corelib/global/qmalloc.cpp
g++ -c -o qmalloc.o -std=c++11 -ffunction-sections -O2 -g <trim> <trim>/qt/5.9.8-4110fa99945/qtbase/src/corelib/global/qmalloc.cpp
```
2. `qmake` is run, and passed our build options, including `-c++std`:
```bash
make[1]: Entering directory '<trim>/qt/5.9.8-4110fa99945/qtbase'
<trim>qt/5.9.8-4110fa99945/qtbase/bin/qmake -o Makefile qtbase.pro -- -bindir <trim>/native/bin -c++std c++1z -confirm-license <trim>
```
3. After some cleaning and configuring, we actually start to build Qt, as well as it's tools and internal libs:
```bash
Building qt...
make[1]: Entering directory '<trim>/qt/5.9.8-4110fa99945/qtbase/src'
# build libpng, zlib etc
gcc -c -m64 -pipe -pipe -O1 <trim> -o .obj/png.o png.c
# build libQt5Bootstrap, using C++11, which again compiles qmalloc.cpp
make[2]: Entering directory '<trim>/qt/5.9.8-4110fa99945/qtbase/src/tools/bootstrap'
g++ -c -pipe -ffunction-sections -O2 -fPIC -std=c++11 <trim> -o .obj/qmalloc.o ../../corelib/global/qmalloc.cpp
# build a bunch of tools like moc, rcc, uic, qfloat16-tables, qdbuscpp2xml, using C++11
g++ -c -pipe -O2 -std=c++11 -fno-exceptions -Wall -W <trim> -o .obj/rcc.o rcc.cpp
# from here, Qt is compiled with -std=c++1z, including qmalloc.cpp, for the third and final time:
g++ -c -include .pch/Qt5Core <trim> -g -Og -fPIC -std=c++1z -fvisibility=hidden <trim> -o .obj/qmalloc.o global/qmalloc.cpp
```
4. Finally, build tools like `lrelease`, `lupdate`, etc, but back to using -std=c++11
```bash
make[1]: Entering directory '<trim>/qt/5.9.8-4110fa99945/qttools/src/linguist/lrelease'
g++ -c -pipe -O2 -std=c++11 -fno-exceptions -Wall -W <trim> -o .obj/translator.o ../shared/translator.cpp
```
If you dump the debug info from the built Qt libs, they should also tell you that they were compiled with `C++17`:
```bash
objdump -g bitcoin/depends/x86_64-pc-linux-gnu/lib/libQt5Core.a
GNU C++17 9.3.0 -m64 -mtune=generic -march=x86-64 -g -O1 -Og -std=c++17 -fPIC -fvisibility=hidden -fvisibility-inlines-hidden -fasynchronous-unwind-tables -fstack-protector-strong -fstack-clash-protection -fcf-protection
```

8f7d1b39ef Fix QPainter non-determinism on macOS (Andrew Chow)

The particular optimization that seems to be causing the problems is that a temp variable is being added for spans->y. For some reason, when it does this, it chooses different instructions to use when making that variable.

This has been around since the original import of Qt
(38be0d13830efd2d98281c645c3a60afe05ffece), however there
are now only two instatnces of it left in the qt codebase,
and from what I can gather, it's unused.
We generate our own Info.plist as part of make deploy, and as far as I
can tell, it doesn't seem to have an effect wether these are present
during qt's build.
I also can't find a single mention of the .app plist in the qt code,
whereas there are multiple instances of .lib.
plugin_no_soname was removed from Qt some time ago, see upstream commit
1d034244c261520d5e739534dc264c2500e02b5f. It was replaced with
plugin_with_soname, however that is currently only used (as of 5.15.x)
in the Android Clang mkspec.
This should mostly be a no-op, however it would seem to make more sense
that we pass through the XCODE_VERSION we now have in depends, rather
than leaving the version set to 4.3.
native_ds_store now takes advantage of Pythons ability to decode binary
plists (since 3.4), so we can drop its biplist dependency.
The call to biplist.Data() in custom_dsstore doesn't seem to do anything,
and from what I can tell can just be removed.
Previously, when running ./configure:
1. With CONFIG_SITE pointed to our depends config.site.in, and
2. PYTHONPATH was not set either in the environment or by the user
The configure would output something like:
PYTHONPATH='depends/x86_64-pc-linux-gnu/share/../native/lib/python3/dist-packages:'
When we really mean:
PYTHONPATH='depends/x86_64-pc-linux-gnu/share/../native/lib/python3/dist-packages'
...without the colon
This change makes sure that:
1. There's no trailing colon, and
2. We use the $PATH_SEPARATOR variable instead of a colon
Files like config.site.in are not referenced by any other script in our
tree, so we need to mark it manually with a "shellcheck shell="
directive and make sure that shellcheck is run on them.
Previously, if ./configure was invoked with:
```
$ env CONFIG_SITE=depends/x86_64-pc-linux-gnu/share/config.site ./configure
```
Where $CONFIG_SITE was a relative path, ./configure would fail with the
following misleading output:
```
checking for boostlib >= 1.58.0 (105800)... yes
checking whether the Boost::System library is available... yes
configure: error: Could not find a version of the Boost::System library!
```
Fully resolving depends_prefix in config.site.in fixes this. To make
sure that there are no other side effects I ran a diff on the
config.status generated by:
1. The scripts prior to this change with CONFIG_SITE set to a full path:
env CONFIG_SITE=$PWD/depends/x86_64-pc-linux-gnu/share/config.site ./configure
2. The scripts after this change with CONFIG_SITE set to a relative path:
env CONFIG_SITE=depends/x86_64-pc-linux-gnu/share/config.site ./configure
And it looks good!

d0a829e963 build: fix mutex detection when building bdb on macOS (fanquake)
Pull request description:
Starting with the Apple Clang shipped with Xcode 12, [Apple has enabled -Werror=implicit-function-declaration by default](https://developer.apple.com/documentation/xcode-release-notes/xcode-12-release-notes):

After #19685 started setting LDFLAGS, the INSTALL_RPATH_USE_LINK_PATH cmake
option used in the libmultiprocess build no longer works, so it is neccessary
to set CMAKE_INSTALL_RPATH as a fallback.
It's unclear currently whether the bad interaction between
INSTALL_RPATH_USE_LINK_PATH and LDFLAGS is a bug, but the issue is reported:

The usage of pragmas within the macOS SDK requires LLVM Clang 8. This is
the version as our prebuilt Clang, however the minimum is worth noting here
as they may diverge and/or expert users might expect they could use an
earlier version.
If you compile using Clang 7 you'll see output like:

Note that this does not _enable_ lto by default in any way, only hooks up the
machinery for -flto to work correctly.
enable-lto-support is explicitly used for pinned-clang because we know it
works. It is neither enabled nor disabled in the external clang case so that
it can be auto-detected.
For depends builds this was fixed by fbcfcf69, which deleted the conflicting
headers. When we no longer control the clang installation, we need to ensure
that the SDK's libc++ headers are used rather than the ones shipped with clang.
We can do that by turning off the default include path and hard-coding our own.
This hard-coded path is ok because we control (via SDK packaging) where these
headers end-up.
Side-note: Now that this path is hard-coded in depends, we can potentially
package the SDK differently, as the c++ folder can live wherever is most
convenient for us.
This should be caught by the differing clang --version outputs, but because we
haven't yet extracted our pinned clang, the system one is actually used for the
version check. That's not a problem because bumping our pinned clang will
cause a rebuild of everything anyway.
a8d39b8840 doc: explain why passing -mlinker-version is required (fanquake)
Pull request description:
I have been down a 🐇 hole. Closes#19359.
When Clang is compiled, [a check is run](https://github.com/llvm/llvm-project/blob/release/8.x/clang/CMakeLists.txt#L353) to define `HOST_LINK_VERSION` as the output of `$CMAKE_LINKER -v`. Note the this is the version of the linker being used to compile Clang itself.. and this check is only run when compiling Clang for macOS.
In the Clang driver, if `HOST_LINK_VERSION` has been defined, there is some additional runtime functionality. An `-mlinker-version` argument, with the value of `HOST_LINK_VERSION` [will be added to the linker arguments](89de0d8dfb/clang/lib/Driver/Driver.cpp (L382)), if `-mlinker-version` has not been passed in by the user.
This is a bit weird, as by default, you are setting `-mlinker-version` to the version of the linker that was used to build the Clang binary, not the linker which will be used when compiling. The commit which introduced the functionality, 628fcf4e3b, described it as a "hack", that should be replaced. However, that was 10 years ago, and the behaviour is still here.
In the Darwin driver, [a check is done](89de0d8dfb/clang/lib/Driver/ToolChains/Darwin.cpp (L208)) for the `-mlinker-version` argument. If there is no argument, the version will default to `0`. Given the above, this should never happen when using Clang for macOS. A series of comparisons are then performed, to check whether the linker version is modern enough to enable certain features, like [`-demangle`](89de0d8dfb/clang/lib/Driver/ToolChains/Darwin.cpp (L215)).
### What this means
#### macOS
A Clang compiled for macOS, i.e `clang+llvm-8.0.0-x86_64-apple-darwin`, will have `HOST_LINKER_VERSION` set to the version of the linker used to compile Clang itself.
At runtime, `-mlinker-version=HOST_LINKER_VERSION` will be added to the linker args, if `-mlinker-version` wasn't passed in. In the Darwin driver, additional arguments, like `-demangle`, will be added to the linker arguments, because `HOST_LINKER_VERSION` was likely some very modern version of `lld` or `ld64`.
#### Linux (cross compilation in depends)
A Clang compiled for Linux, i.e `clang+llvm-8.0.0-x86_64-linux-gnu-ubuntu-14.04`, which we now use for macOS builds in depends, will behave differently. As it's built for Linux, `HOST_LINKER_VERSION` was not defined at compile time, and there will be no default behaviour of appending `-mlinker-version=HOST_LINKER_VERSION` to the linker args. Thus, unless you pass in `-mlinker-version` yourself, when the version checks are done in the Darwin driver, no modern linker features will be enabled, as the version will have defaulted to `0`.
Therefore, it's important that we continue to pass `-mlinker-version="our LD64 version"` as part of our compilation flags, if we want to have "modern" linker features enabled for our macOS builds.
#### Summary
[Clang 8](https://releases.llvm.org/download.html#8.0.0). Building a macOS binary. Link line with path arguments trimmed.
| | default behaviour | `-mlinker-version=100` (`-demangle threshold`) | `-mlinker-version=530` |
| - | --------------- | --------------------- | ---------------------- |
| macOS Clang | `-demangle -lto_library ../libLTO.dylib -no_deduplicate -dynamic -arch x86_64 -macosx_version_min 10.15.0 -o a.out ../test-b8b9b3.o -lc++ -lSystem ../libclang_rt.osx.a` | `-demangle -dynamic -arch x86_64 -macosx_version_min 10.15.0 -o a.out ../test-a66966.o -lc++ -lSystem ../libclang_rt.osx.a` | same as default |
| Linux Clang | `-dynamic -arch x86_64 -macosx_version_min 10.12.0 -o a.out ../test-bfce57.o -lc++ -lSystem` | `-demangle -dynamic -arch x86_64 -macosx_version_min 10.12.0 -o a.out ../test-a846a3.o -lc++ -lSystem` | `-demangle -lto_library ../libLTO.dylib -no_deduplicate -dynamic -arch x86_64 -macosx_version_min 10.12.0 -o a.out ../test-de0280.o -lc++ -lSystem` |
Note: Most links here are pointing to the 8.x branch of LLVM/Clang, as we are using that version in depends.
Note: To add a little more confusion, you wont see `-mlinker-version X` in your compile flags, you'll see [`-target-linker-version X`](431daedee4/clang/lib/Driver/ToolChains/Clang.cpp (L4777)).

This enables of the use of AI_* definitions in the Windows headers,
specifically AI_ADDRCONFIG, which fixes an issue with libevent and
ipv6 on Windows.
It also aligns with what we define in configure when building Core.
libevent uses getaddrinfo when available, and falls back to gethostbyname
Windows has both, but gethostbyname only supports IPv4
libevent fails to detect Windows's getaddrinfo due to not including the right headers
This patches libevent's configure script to check it correctly
