f570bd91b3 refs/files: deprecate writing symrefs as symbolic links
The "files" backend has the ability to store symbolic refs as symbolic
links, which can be configured via "core.preferSymlinkRefs". This
feature stems back from the early days: the initial implementation of
symbolic refs used symlinks exclusively. The symref format was only
introduced in 9b143c6e15 (Teach update-ref about a symbolic ref stored
in a textfile., 2005-09-25) and made the default in 9f0bb90d16
(core.prefersymlinkrefs: use symlinks for .git/HEAD, 2006-05-02).

This is all about 20 years ago, and there are no known reasons nowadays
why one would want to use symlinks instead of symrefs. Mark the feature
for deprecation in Git 3.0.

Note that this only deprecates _writing_ symrefs as symbolic links.
Reading such symrefs is still supported for now.

e509b5b8be rust: support for Windows
The initial patch series that introduced Rust into the core of Git only
cared about macOS and Linux. This specifically leaves out Windows, which
indeed fails to build right now due to two issues:

  - The Rust runtime requires `GetUserProfileDirectoryW()`, but we don't
    link against "userenv.dll".

  - The path of the Rust library built on Windows is different than on
    most other systems systems.

Fix both of these issues to support Windows.

Note that this commit fixes the Meson-based job in GitHub's CI. Meson
auto-detects the availability of Rust, and as the Windows runner has
Rust installed by default it already enabled Rust support there. But due
to the above issues that job fails consistently.

Install Rust on GitLab CI, as well, to improve test coverage there.

1b43384f41 ci: verify minimum supported Rust version
In the current state of our Rust code base we don't really have any
requirements for the minimum supported Rust version yet, as we don't use
any features introduced by a recent version of Rust. Consequently, we
have decided that we want to aim for a rather old version and edition of
Rust, where the hope is that using an old version will make alternatives
like gccrs viable earlier for compiling Git.

But while we specify the Rust edition, we don't yet specify a Rust
version. And even if we did, the Rust version would only be enforced for
our own code, but not for any of our dependencies.

We don't yet have any dependencies at the current point in time. But
let's add some safeguards by specifying the minimum supported Rust
version and using cargo-msrv(1) to verify that this version can be
satisfied for all of our dependencies.

Note that we fix the version of cargo-msrv(1) at v0.18.1. This is the
latest release supported by Ubuntu's Rust version.

03f3900fb2 rust/varint: add safety comments
The `decode_varint()` and `encode_varint()` functions in our Rust crate
are reimplementations of the respective C functions. As such, we are
naturally forced to use the same interface in both Rust and C, which
makes use of raw pointers. The consequence is that the code needs to be
marked as unsafe in Rust.

It is common practice in Rust to provide safety documentation for every
block that is marked as unsafe. This common practice is also enforced by
Clippy, Rust's static analyser. We don't have Clippy wired up yet, and
we could of course just disable this check. But we're about to wire it
up, and it is reasonable to always enforce documentation for unsafe
blocks.

Add such safety comments to already squelch those warnings now. While at
it, also document the functions' behaviour.

e75cd05900 ci: check formatting of our Rust code
Introduce a CI check that verifies that our Rust code is well-formatted.
This check uses `cargo fmt`, which is a wrapper around rustfmt(1) that
executes formatting for all Rust source files. rustfmt(1) itself is the
de-facto standard for formatting code in the Rust ecosystem.

The rustfmt(1) tool allows to tweak the final format in theory. In
practice though, the Rust ecosystem has aligned on style "editions".
These editions only exist to ensure that any potential changes to the
style don't cause reformats to existing code bases. Other than that,
most Rust projects out there accept this default style of a specific
edition.

Let's do the same and use that default style. It may not be anyone's
favorite, but it is consistent and by making it part of our CI we also
enforce it right from the start.

Note that we don't have to pick a specific style edition here, as the
edition is automatically derived from the edition we have specified in
our "Cargo.toml" file.

The implemented script looks somewhat weird as we perfom manual error
handling instead of using something like `set -e`. The intent here is
that subsequent commits will add more checks, and we want to execute all
of these checks regardless of whether or not a previous check failed.

0de14fe3f3 ci: deduplicate calls to apt-get update
When installing dependencies we first check for the distribution that is
in use and then we check for the specific job. In the first step we
already install all dependencies required to build and test Git, whereas
the second step installs a couple of additional dependencies that are
only required to perform job-specific tasks.

In both steps we use `apt-get update` to update our repository sources.
This is unnecessary though: all platforms that use Aptitude would have
already executed this command in the distro-specific step anyway.

Drop the redundant calls.
