a58868d201 build: Makes rcc output always deterministic (Hennadii Stepanov)
Pull request description:
The Qt Resource Compiler ([rcc](https://doc.qt.io/qt-5/rcc.html)) has a command-line option `--format-version` which has the [default value](https://code.qt.io/cgit/qt/qtbase.git/tree/src/tools/rcc/main.cpp?h=5.12.10#n172) 2.
The only difference from `--format-version 1` is adding a [last modified timestamp](https://code.qt.io/cgit/qt/qtbase.git/tree/src/tools/rcc/rcc.cpp?h=5.12.10#n207) to the output file ([credits](https://github.com/bitcoin/bitcoin/pull/21654#issuecomment-819198228) to **fanquake**). That, in turn, forces us to use `QT_RCC_SOURCE_DATE_OVERRIDE=1` to get deterministic builds (#13732).
This change makes rcc output always deterministic by using `--format-version 1` option that makes usage of the
`QT_RCC_SOURCE_DATE_OVERRIDE` needless.

Also it improves interaction with ccache:

42b589d18f scripts: test for MACHO control flow instrumentation (fanquake)
469a5bc4fa build: build Boost with -fcf-protection when targeting Darwin (fanquake)
Pull request description:
Addresses the macOS portion of #21888.
Build Boost with `-fcf-protection` when targeting Darwin. This should be ok, because our cross-compiler (Clang 10) supports the option, and I'd expect all versions of Apple Clang being used to compile Core would also support it. Building Boost with this option is required so that the `main` provided to `test_bitcoin` has instrumentation.
Note that the presence of instrumentation does not mean it will be used, as that is determined at runtime by the CPU.
From the Intel control flow enforcement documentation:
> The ENDBR32 and ENDBR64 instructions will have the same effect as the NOP instruction on Intel 64 processors that do not support CET. On processors supporting CET, these instructions do not change register or flag state. This allows CET instrumented programs to execute on processors that do not support CET. Even when CET is supported and enabled, these NOP–like instructions do not affect the execution state of the program, do not cause any additional register pressure, and are minimally intrusive from power and performance perspectives.
Follow up from #21135.

The LLVM Clang we use for cross-compilation supports this option, and it's expected
that any builders on macOS will also be using an Apple Clang that supports it.
c799a19b4b build, qt: No longer need to set QT_RCC_TEST=1 for determinism (Hennadii Stepanov)
Pull request description:
The Qt Resource Compiler (rcc) output order relies on [`QHash`](https://doc.qt.io/qt-5/qhash.html):
> This randomization of `QHash` is enabled by default. Even though programs should never depend on a particular `QHash` ordering, there may be situations where you temporarily need deterministic behavior, for example for debugging or regression testing. To disable the randomization, define the environment variable `QT_HASH_SEED` to have the value 0.
Since #3620 we use `QT_RCC_TEST=1` to achieve a deterministic output.
Since Qt 5.3.1 hash seeding is disabled for all of the bootstrapped tools, including rcc. Therefore, `QT_RCC_TEST=1` is no longer needed.

This relatively easy change eliminates all runtime dependencies (except
for the kernel) for dmg, which is the only native build tool that gets
put in our output tarballs.
This allows much more flexibility when constructing the codesigning
environment, and is much more robust.

Pull request description:
This PR is the third and final piece of the basic Android support puzzle - it depends on https://github.com/bitcoin/bitcoin/pull/16110 and is related to https://github.com/bitcoin/bitcoin/pull/16883. It introduces an `android` directory under `qt` and a simple way to build an Android package of `bitcoin-qt`:
1. Build depends for Android as described in the [README](https://github.com/bitcoin/bitcoin/blob/master/depends/README.md)
2. Configure with one of the resulting prefixes
3. Run `make && make apk` in `src/qt`
The resulting APK files will be in `android/build/outputs/apk`. You can install them manually or with [adb](https://developer.android.com/studio/command-line/adb). One can also open the `android` directory in Android Studio for that integrated development and debugging experience. `BitcoinQtActivity` is your starting point.
Under the hood makefile `apk` target:
1. Renames the `bitcoin-qt` binary to `libbitcoin-qt.so` and copies it over to a folder under `android/libs` depending on which prefix and corresponding [ABI](https://developer.android.com/ndk/guides/abis.html#sa) `bitcoin-qt` was built for
2. Takes `libc++_shared.so` from the Android NDK and puts in the same place. It [must be included](https://developer.android.com/ndk/guides/cpp-support) in the APK
3. Extracts Qt for Android Java support files from the `qtbase` archive in `depends/sources` to `android/src`
There is also just a tiny bit of `ifdef`'d code to make the Qt Widgets menus usable. It's not pretty but it works and is a stepping stone towards https://github.com/bitcoin/bitcoin/pull/16883.

180dc3c886 build: miniupnpc 2.2.2 (fanquake)
Pull request description:
Creating the dll subdir is no-longer required.
We can drop our wingen patch.
One issue that came up in [#19867](https://github.com/bitcoin/bitcoin/pull/19867#discussion_r483516359):
> unrelated to this change but: why are we inserting the architecture in here, seems like something not necessary to reveal
> My assumption is that it was being inserted to make depends more deterministic. However I think we can improve this, as there's no reason to reveal more of the version information either. Could leave the version as is /2.0 and either drop the architecture, or insert something else?
I've dropped our `sed` and added a patch that just removes the OS string and miniupnpc version from the User-Agent. i.e:
```bash
# master
strings depends/x86_64-apple-darwin19.6.0/lib/libminiupnpc.a | rg -i User-Agent
User-Agent: x86_64-apple-darwin19.6.0, UPnP/1.1, MiniUPnPc/2.0.20180203

strings depends/x86_64-apple-darwin19.6.0/lib/libminiupnpc.a | rg -i User-Agent
User-Agent: UPnP/1.1

```
Note that built unmodified (22c1386351), the User-Agent would be:
```bash
strings libminiupnpc.dylib | rg User-Agent
User-Agent: Darwin/19.6.0, UPnP/1.1, MiniUPnPc/2.2.0

This tries to invoke xcrun, which is not available when cross-compiling.
Given we are in control of the SDK versions being used, removing this
check has minimal-no effect.

A fix for QTBUG-34748 was introduced in #5915 (v0.11.0, Qt 5.2.1).
QTBUG-34748 was fixed in version 5.3.0.
The separated patch file, provided by #5915, was dropped in #12971 while
bumping Qt to 5.9.4 (5.9.6). But libxcb.mk remained unchanged.
This change reverts #5915 for libxcb.mk.
The source we are currently using is from 2015. The upstream repo has
received a small number of bug fixes and improvements since then.
Including one that fixes an issue for Windows users:
https://github.com/miniupnp/libnatpmp/pull/13.
The source we are currently using is the most recent "official" release,
however I don't think it's worth waiting for a new one. The maintainer
was prompted to do so in Oct 2020, then again in Jan of this year, and
no release has eventuated. Given libnatpmp is a new inclusion into our
repository, I think we should be using this newer source.
This also cleans up a few warnings we currently see in depends builds:

Currently, our cross-compile of libnatpmp for macOS doesn't work at all.
The wrong archiver is used, which produces an archive the linker doesn't like.
This becomes clear when configuring:
```bash
configure:25722: checking for initnatpmp in -lnatpmp
configure:25747: env -u C_INCLUDE_PATH -u CPLUS_INCLUDE_PATH -u OBJC_INCLUDE_PATH -u OBJCPLUS_INCLUDE_PATH -u CPATH -u LIBRARY_PATH /home/ubuntu/bitcoin/depends/x86_64-apple-darwin18/native/bin/clang++ --target=x86_64-apple-darwin18 <trim> -Wl,-headerpad_max_install_names -Wl,-dead_strip -Wl,-dead_strip_dylibs conftest.cpp -lnatpmp >&5
ld: archive has no table of contents for architecture x86_64
clang: error: linker command failed with exit code 1 (use -v to see invocation)
```
Fix this by using the right `ar` (we do the same for upnp).
While we're at it, we fixe the build so that we are using our c/ppflags.
This means building with `-O2` rather than `-Os`.
Note that this fixes an issue that is also fixed by #21209.
However, given there are reservations about updating to use a newer libnatpmp source, we should just fix this for now.
