The `git` executable has these two very useful options:
-C <directory>:
switch to the specified directory before performing any actions
-c <key>=<value>:
temporarily configure this setting for the duration of the
specified scalar subcommand
With this commit, we teach the `scalar` executable the same trick.
Note: It might look like a good idea to try to reuse the
`handle_options()` function in `git.c` instead of replicating only the
`-c`/`-C` part. However, that function is not only not in `libgit.a`, it
is also intricately entangled with the rest of the code in `git.c` that
is necessary e.g. to handle `--paginate`. Besides, no other option
handled by that `handle_options()` function is relevant to Scalar,
therefore the cost of refactoring vastly would outweigh the benefit.

Delete an enlistment by first unregistering the repository and then
deleting the enlistment directory (usually the directory containing the
worktree `src/` directory).
On Windows, if the current directory is inside the enlistment's
directory, change to the parent of the enlistment directory, to allow us
to delete the enlistment (directories used by processes e.g. as current
working directories cannot be deleted on Windows).

After a Scalar upgrade, it can come in really handy if there is an easy
way to reconfigure all Scalar enlistments. This new option offers this
functionality.

This comes in handy during Scalar upgrades, or when config settings were
messed up by mistake.

Just like `git clone`, the `scalar clone` command now also offers to
restrict the clone to a single branch.

This implements Scalar's opinionated `clone` command: it tries to use a
partial clone and sets up a sparse checkout by default. In contrast to
`git clone`, `scalar clone` sets up the worktree in the `src/`
subdirectory, to encourage a separation between the source files and the
build output (which helps Git tremendously because it avoids untracked
files that have to be specifically ignored when refreshing the index).
Also, it registers the repository for regular, scheduled maintenance,
and configures a flurry of configuration settings based on the
experience and experiments of the Microsoft Windows and the Microsoft
Office development teams.
Note: since the `scalar clone` command is by far the most commonly
called `scalar` subcommand, we document it at the top of the manual
page.

When a user deleted an enlistment manually, let's be generous and
_still_ unregister it.

To test the Scalar command, create a test script in contrib/scalar/t
that is executed as `make -C contrib/scalar test`. Since Scalar has no
meaningful capabilities yet, the only test is rather simple. We will add
more tests in subsequent commits that introduce corresponding, new
functionality.
Note: This test script is intended to test `scalar` only lightly, even
after all of the functionality is implemented.
A more comprehensive functional (or: integration) test suite can be
found at https://github.com/microsoft/scalar; It is used in the workflow
https://github.com/microsoft/git/blob/HEAD/.github/workflows/scalar-functional-tests.yml
in Microsoft's Git fork. This test suite performs end-to-end tests with
a real remote repository, and is run as part of the regular CI and PR
builds in that fork.
Since those tests require some functionality supported only by
Microsoft's Git fork ("GVFS protocol"), there is no intention to port
that fuller test suite to `contrib/scalar/`.
