Fix a typo in the split-objs/split-sections warning message

GitLab CI: Add aarch64-linux-deb{10,11}

It is no longer just x86_64.

Allow no-comments, quiet, simple, minimal in init section of config

This reverts commit 80a524c5.

Reason: fails the whitespace check in our CI.

* Bump versions on master branch to 3.11

* Try to fix CI by setting cabal-testsuite stable Cabal version to 3.8 back again

* Update bootstrap configuration

* Work around bounds problem with cabal-install-parsers

* Update bootstrap files

* Try to update the Custom setup cabal to 3.10 according to Artem's suggestion

* CI: cabal-3.10 compat: actions/cache has to go before cabal update

* Fix failing old GHC CI builds by adding XDG's ~/.local/bin to GITHUB_PATH

Stabilize use of brew in GitLab CI

Use a specific release instead of HEAD.

Add 3.10.1.0 changelogs and remove the used up tiny changlog files

Return empty default when git fails

Add maybe in guess functions

Adjust type in NonInteractive

Change unit tests

Fix whitespace

Abstract guessing and remove comments

Simplify guess functions

Return default for cabal init author and name when git fails

* Disable everfailing assertion

See discussion at https://github.com/haskell/cabal/issues/6006



* Fix unused parameter

* Bump ci-images pin

* Combine Debian 10 and 11 in a matrix job

* Add most of the GHC 9.6.1 platforms that fit on the x86_64 runners

* Add centos7

Extends the "configure" logic in .gitlab/ci.sh :(

* Remove platforms unsupported by GHC 9.6.1 or Cabal 3.8.1

* Remove aarch64-linux-deb10

GHCUp fails to run on aarch64-linux-deb10 due to a glibc mismatch.

aarch64-linux-deb11 would work, but there is no GHC release for that
version yet.

* Reset GitLab CI verbosity

Add --project-dir flag

* Split Distribution.Simple.Setup into smaller modules

The main motivation is to improve parallelism of the module graph.
This improves compile times as we can benefit more from multiple cores,
but also because GHC is superlinear in the size and complexity of source
files.

Each set of command line options is moved to its own file, and common
utilities are moved into .Common.

The interface is kept the same and new modules aren't exposed.

* Refine some imports of Distribution.Simple.Setup

* fixup! Split Distribution.Simple.Setup into smaller modules

fix whitespace

* Refine imports of Distribution.Simple.Setup in Cabal

Replace imports of Distribution.Simple.Setup with direct imports of
the modules that it re-exports. Some imports are left if most
re-exported modules are used.

* Add a changelog entry

Add `Distribution.Client.Main`

This makes it easier to integrate `cabal-install` into other tools.

Add traceM and traceShowM

Cabal codebase has its fair share of Applicatives/Monads. Adding
traceM and traceShowM to the Prelude.Compat is quite convenient
for testing purposes.

Changing a file from `extra-source-files` causes `cabal build` to
reevaluate the build plan, judging from the following behavior.

```console
$ cabal build
...

$ cabal build
Up to date

  # Make a change to any of the extra-source-files, e.g. Foo.txt

$ cabal build
...
In order, the following would be built (use -v for more details):
 - ... (lib) (file Foo.txt changed)
...
```

One notes here that the 3rd `cabal build` does not just output "Up to date".

Doc: bump to Python 3.10; Sphinx 5.3.0. Remove `--constraint: foo -none` & some polishing

For the moment, readthedocs.org does not support Sphinx 6.

- `PACKAGE -none` as already been removed in 3.4 as valid constraint.
(I guess this is now flag syntax.)

- Important constraint `installed` was just buried in an example, I made
it stand out more in a bullet point.
Same for `source`, even though this is an exotic constraint.

- Highlight constraint `installed` in connection with `allow-newer`.

- Group `test` and `bench` constraint with the `+/-FLAG` constraints.

Fixup: Apply concrete suggestions from code review

Fixes suggested by @ulysses4ever, thanks@
