cdb41d5573b1e2ed1bc1d8d1dc9f77e82672ee1f doc: Install Rosetta on M1-macOS for qt in depends (Hennadii Stepanov)
Pull request description:
On master (c609e10545492aba480ff17aff7eefc13a0b5cd8) `make -C depends qt` on Apple Silicon based macOS 11.4 ends with an error:
```
/bin/sh: /Users/hebasto/bitcoin/depends/work/build/aarch64-apple-darwin20.5.0/qt/5.12.11-6c4d47a8f8f/qtbase/bin/moc: Bad CPU type in executable
```
Installing Rosetta 2 fixes it.
Explanation. On Apple Silicon macOS the `qt` package in depends actually is cross compiled. All native tools (including `moc`) are x86_64 binaries, that require Rosetta 2 to run.

Pull request description:
This reduces the amount of syntax noise in the makefiles.
Setting V=1 still enables verbose logging.
The only noticeable difference in behavior is that, unless V=1 is specified, make won't print its own messages like
make: Nothing to be done for 'all', make: 'all' is up to date, or touch <file>, if -t is specified.

fa872c9af397837bb17859b5f43adec71239682a depends: Fix id_string invocations (Carl Dong)
Pull request description:
Closes: #21242
```
Reproduced from depends/Makefile comment:
When invoking a shell, GNU Make special-cases exit code 127 (command not
found) by not capturing the output but instead passing it through. This
is not done for any other exit code.
Therefore, we require a "|| true" to avoid this behaviour when in an
environment where the build_* or host_* may not exist yet.

There seems to be some confusion about exactly how to use depends, when to pass a prefix to `./configure` etc (see #16367, #16654).
I've cherry-picked two of russ's commits out of #16367, as they are clear stand-alone improvements and we don't have to wait for #16367 to improve the depends documentation.

Pull request description:
Since #8210 (59d063d076), we've been passing `-dbus-runtime` when configuring Qt.
```
qtbase-opensource-src-5.9.7 $ ./configure -h | grep -i dbus
-no-dbus ............. Do not build the Qt D-Bus module
-dbus-linked ......... Build Qt D-Bus and link to libdbus-1 [auto]
-dbus-runtime ........ Build Qt D-Bus and dynamically load libdbus-1 [no]
```
This means we don't actually seem to be using the `D-Bus` we build in depends. This was pointed out by theuni at the time, [here](https://github.com/bitcoin/bitcoin/pull/7993#issuecomment-223114395) and [here](https://github.com/bitcoin/bitcoin/pull/8210#issuecomment-226930545), but was never followed up. dongcarl also bought it up as part of #16150.
I've tested building and running `bitcoin-qt` using depends on Debian. Needs further testing.

which are currently the most recent releases available as open source. See upstream [`cctools`](https://github.com/tpoechtrager/cctools-port/commits/973.0.1-ld64-609) and [`libtapi`](https://github.com/tpoechtrager/apple-libtapi/tree/1100.0.11).
This should improve the possibility of Apple ARM cross-compilation in depends.
This also removes our [patching out of pthreads usage](https://github.com/bitcoin/bitcoin/blob/master/depends/patches/native_cctools/ld64_disable_threading.patch) in `ld64`. There have been multiple changes since `ld64 450.3`, which have likely fixed the non-determinism we were working around. i.e from [InputFiles.cpp](https://opensource.apple.com/source/ld64/ld64-609/src/ld/InputFiles.cpp.auto.html):
```cpp
// <rdar://problem/15002251> make implicit dylib order be deterministic by sorting by install_name
std::sort(implicitDylibs.begin(), implicitDylibs.end(), DylibByInstallNameSorter());
```
```cpp

std::sort(unprocessedDylibs.begin(), unprocessedDylibs.end(), [](const ld::dylib::File* lhs, const ld::dylib::File* rhs) {
return strcmp(lhs->path(), rhs->path()) < 0;

```
guix: Record precious directories and add guix-clean
Many users have reported problems that stem from having an unclean
working tree. To that end, I've written a guix-clean script which should
help reset the working tree while respecting user-specified precious
directories.
Precious directories, such as:
- SOURCES_PATH
- BASE_CACHE
- SDK_PATH
- OUTDIR
Should be preserved when cleaning the working tree, and are thus
recorded in ./contrib/guix/var/precious_dirs.
The ./contrib/guix/guix-clean script is able to parse that file and make
sure to avoid them when cleaning out the working tree.

d5a71e97853ea9e1b879e8c76bfb01d4bef33172 guix: Use --cores instead of --max-jobs (Carl Dong)
Pull request description:
This PR addresses a few hiccups encountered by the brave souls who've been experimenting with the Guix scripts:
- Resolves confusion between `--cores=` and `--max-jobs=`
- `guix`'s `--cores=` actually corresponds to make's `--jobs=`, so let's just control `--cores=` with our overridable env var
- `git-describe` will scream `fatal: no tag exactly matches '<hash>'` when looking for a tag, but we don't care, so silence that
- `windeploy/unsigned` should be inside `distsrc-*` and created idempotently (sorry I know this one annoyed people)
- Add troubleshooting documentation to `README.md`
- Add early health check for `guix-daemon` in case user forgot to start a `guix-daemon`
- Depending on configuration, a `--fallback` flag may be needed to tell Guix to not fail if substitutes fail but fallback to building locally
- `codesign_allocate` and `pagestuff` are now unnecessary for codesigning as we're now using `signapple`
A few robustness changes are also included:
- We supply the `--link-profile` flag, as some Guix packages may expect the profile to be available under `$HOME/.guix-profile`
- We now clear and manually set all toolchain-related env vars (e.g. `C*_INCLUDE_PATH`) ourselves, after patching a Qt::moc bug
- We use the native `clang-toolchain` package for darwin builds instead of `clang`, lining up with all our other toolchain packages.
Finally, we restructure the guix building hierarchy such that it looks something like:
```

```
Separating guix builds by their version identifier (basically namespacing them) allows us to change the layout in the future without worry about potential naming conflicts.

### Guix Introduction
This PR enables building bitcoin in Guix containers. [Guix](https://www.gnu.org/software/guix/manual/en/html_node/Features.html) is a transactional package manager much like Nix, but unlike Nix, it has more of a focus on [bootstrappability](https://www.gnu.org/software/guix/manual/en/html_node/Bootstrapping.html) and [reproducibility](https://www.gnu.org/software/guix/blog/tags/reproducible-builds/) which are attractive for security-sensitive projects like bitcoin.
### Guix Build Walkthrough
Please read the `README.md`.

<details>
<summary>Old instructions no. 1</summary>
In this PR, we define a Guix [manifest](https://www.gnu.org/software/guix/manual/en/html_node/Invoking-guix-package.html#profile_002dmanifest) in `contrib/guix/manifest.scm`, which declares what packages we want in our environment.
We can then invoke
```
guix environment --manifest=contrib/guix/manifest.scm --container --pure --no-grafts --no-substitutes
```
To have Guix:
1. Build an environment containing the packages we defined in our `contrib/guix/manifest.scm` manifest from the Guix bootstrap binaries (see [bootstrappability](https://www.gnu.org/software/guix/manual/en/html_node/Bootstrapping.html) for more details).
2. Start a container with that environment that has no network access, and no access to the host's filesystem except to the `pwd` that it was started in.
3. Drop you into a shell in that container.
> Note: if you don't want to wait hours for Guix to build the entire world from scratch, you can eliminate the `--no-substitutes` option to have Guix download from available binary sources. Note that this convenience doesn't necessarily compromise your security, as you can check that a package was built correctly after the fact using `guix build --check <packagename>`
Therefore, we can perform a build of bitcoin much like in Gitian by invoking the following:
```
make -C depends -j"$(nproc)" download && \
cat contrib/guix/build.sh | guix environment --manifest=contrib/guix/manifest.scm --container --pure --no-grafts --no-substitutes
```
We don't include `make -C depends -j"$(nproc)" download` inside `contrib/guix/build.sh` because `contrib/guix/build.sh` is run inside the container, which has no network access (which is a good thing).
</details>
### Rationale
I believe that this represents a substantial improvement for the "supply chain security" of bitcoin because:
1. We no longer have to rely on Ubuntu for our build environment for our releases ([oh the horror](72bd4ab867/contrib/gitian-descriptors/gitian-linux.yml (L10))), because Guix builds everything about the container, we can perform this on almost any Linux distro/system.
2. It is now much easier to determine what trusted binaries are in our supply chain, and even make a nice visualization! (see [bootstrappability](https://www.gnu.org/software/guix/manual/en/html_node/Bootstrapping.html)).
3. There is active effort among Guix folks to minimize the number of trusted binaries even further. OriansJ's [stage0](https://github.com/oriansj/stage0), and janneke's [Mes](https://www.gnu.org/software/mes/) all aim to achieve [reduced binary boostrap](http://joyofsource.com/reduced-binary-seed-bootstrap.html) for Guix. In fact, I believe if OriansJ gets his way, we will end up some day with only a single trusted binary: hex0 (a ~500 byte self-hosting hex assembler).
### Steps to Completion
- [x] Successfully build bitcoin inside the Guix environment
- [x] Make `check-symbols` pass
- [x] Do the above but without nasty hacks
- [x] Solve some of the more innocuous hacks
- [ ] Make it cross-compile (HELP WANTED HERE)
- [x] Linux
- [x] x86_64-linux-gnu
- [x] i686-linux-gnu
- [x] aarch64-linux-gnu
- [x] arm-linux-gnueabihf
- [x] riscv64-linux-gnu
- [ ] OS X
- [ ] x86_64-apple-darwin14
- [ ] Windows
- [ ] x86_64-w64-mingw32
- [ ] Maybe make importer for depends syntax
- [ ] Document build process for future releases
- [ ] Extra: Pin the revision of Guix that we build with with Guix [inferiors](https://www.gnu.org/software/guix/manual/en/html_node/Inferiors.html)

As of now, the command described above to perform a build of bitcoin a lot like Gitian works, but fails at the `check-symbols` stage. This is because a few dynamic libraries are linked in that shouldn't be.
Here's what `ldd src/bitcoind` looks like when built in a Guix container:
```
linux-vdso.so.1 (0x00007ffcc2d90000)
libdl.so.2 => /gnu/store/h90vnqw0nwd0hhm1l5dgxsdrigddfmq4-glibc-2.28/lib/libdl.so.2 (0x00007fb7eda09000)
librt.so.1 => /gnu/store/h90vnqw0nwd0hhm1l5dgxsdrigddfmq4-glibc-2.28/lib/librt.so.1 (0x00007fb7ed9ff000)
libstdc++.so.6 => /gnu/store/4sqps8dczv3g7rwbdibfz6rf5jlk7w90-gcc-5.5.0-lib/lib/libstdc++.so.6 (0x00007fb7ed87c000)
libpthread.so.0 => /gnu/store/h90vnqw0nwd0hhm1l5dgxsdrigddfmq4-glibc-2.28/lib/libpthread.so.0 (0x00007fb7ed85b000)
libm.so.6 => /gnu/store/h90vnqw0nwd0hhm1l5dgxsdrigddfmq4-glibc-2.28/lib/libm.so.6 (0x00007fb7ed6da000)
libgcc_s.so.1 => /gnu/store/4sqps8dczv3g7rwbdibfz6rf5jlk7w90-gcc-5.5.0-lib/lib/libgcc_s.so.1 (0x00007fb7ed6bf000)
libc.so.6 => /gnu/store/h90vnqw0nwd0hhm1l5dgxsdrigddfmq4-glibc-2.28/lib/libc.so.6 (0x00007fb7ed506000)
/gnu/store/h90vnqw0nwd0hhm1l5dgxsdrigddfmq4-glibc-2.28/lib/ld-linux-x86-64.so.2 => /usr/lib64/ld-linux-x86-64.so.2 (0x00007fb7ee3a0000)
```
And here's what it looks in one of our releases:
```
linux-vdso.so.1 (0x00007ffff52cd000)
libpthread.so.0 => /usr/lib/libpthread.so.0 (0x00007f87726b4000)
librt.so.1 => /usr/lib/librt.so.1 (0x00007f87726aa000)
libm.so.6 => /usr/lib/libm.so.6 (0x00007f8772525000)
libgcc_s.so.1 => /usr/lib/libgcc_s.so.1 (0x00007f877250b000)
libc.so.6 => /usr/lib/libc.so.6 (0x00007f8772347000)
/lib64/ld-linux-x86-64.so.2 => /usr/lib64/ld-linux-x86-64.so.2 (0x00007f8773392000)
```
~~I suspect it is because my script does not apply the gitian-input patches [described in the release process](https://github.com/bitcoin/bitcoin/blob/master/doc/release-process.md#fetch-and-create-inputs-first-time-or-when-dependency-versions-change) but there is no description as to how these patches are applied.~~ It might also be something else entirely.
Edit: It is something else. It appears that the gitian inputs are only used by [`gitian-win-signer.yml`](d6e700e40f/contrib/gitian-descriptors/gitian-win-signer.yml (L14))

## Issue being fixed or feature implemented
Seems as `cmake` package is not needed anymore so far as `immer` moved
inside src/ directory.
`immer` is integrated to our Makefile.am and do not requires extra call
of cmake as it used to be.
## What was done?
Removed cmake from list of packages and removed package `cmake.mk`
## How Has This Been Tested?
Tested build with HEAD - succeed.
After that reverted to the old revision that have `immer` package
(85d6cadbfa).
Failed as expected:
```
make: *** No rule to make target 'cmake', needed by '/home/knst/projects/dash/depends/built/x86_64-pc-linux-gnu/bls-dash/bls-dash-1.2.0-6213882c069.tar.gz'. Stop.
```
