A user reported issues with 'scalar clone' and 'scalar register' when
working in an environment that had locked down the ability to run
'crontab' or 'systemctl' in that those commands registered as _failures_
instead of opportunistically reporting a success with just a warning
about background maintenance.
As a workaround, they can use GIT_TEST_MAINT_SCHEDULER to fake a
successful background maintenance, but this is not a viable strategy for
long-term.
Update 'scalar register' and 'scalar clone' to no longer fail by
modifying register_dir() to only warn when toggle_maintenance(1) fails.
Since background maintenance is a "nice to have" and not a requirement
for a working repository, it is best to move this from hard error to
gentle warning.

Sometimes when users use scalar to download a monorepo with a long
commit history, they want to check the progress bar to know how long
they still need to wait during the fetch process, but scalar
suppresses this output by default.
So let's check whether scalar stderr refer to a terminal, if so,
show progress, otherwise disable it.

The recent addition of the index.skipHash config option allows index
writes to speed up by skipping the hash computation for the trailing
checksum. This is particularly critical for repositories with many files
at HEAD, so add this config option to two cases where users in that
scenario may opt-in to such behavior:
1. The feature.manyFiles config option enables some options that are
helpful for repositories with many files at HEAD.
2. 'scalar register' and 'scalar reconfigure' set config options that
optimize for large repositories.
In both of these cases, set index.skipHash=true to gain this
speedup. Add tests that demonstrate the proper way that
index.skipHash=true can override feature.manyFiles=true.

'scalar reconfigure -a' is taught to automatically remove
scalar.repo entires which no longer exist.

tests(scalar): tighten the stale `scalar.repo` test some
scalar reconfigure -a: remove stale `scalar.repo` entries
Every once in a while, a Git for Windows installation fails because the
attempt to reconfigure a Scalar enlistment failed because it was deleted
manually without removing the corresponding entries in the global Git
config.
In f5f0842d0b (scalar: let 'unregister' handle a deleted enlistment
directory gracefully, 2021-12-03), we already taught `scalar delete` to
handle the case of a manually deleted enlistment gracefully. This patch
adds the same graceful handling to `scalar reconfigure --all`.
This patch is best viewed with `--color-moved`.

Build argument list and environment of child processes by using
struct child_process and populating its members "args" and "env"
directly instead of maintaining separate strvecs and letting
run_command_v_opt() and friends populate these members. This is
simpler, shorter and slightly more efficient.

The 'scalar unregister' command removes a repository from the list of
registered Scalar repositories and removes it from the list of
repositories registered for background maintenance. If the repository
was not already registered for background maintenance, then the command
fails, even if the repository was still registered as a Scalar
repository.
After using 'scalar clone' or 'scalar register', the repository would be
enrolled in background maintenance since those commands run 'git
maintenance start'. If the user runs 'git maintenance unregister' on
that repository, then it is still in the list of repositories which get
new config updates from 'scalar reconfigure'. The 'scalar unregister'
command would fail since 'git maintenance unregister' would fail.
Further, the add_or_remove_enlistment() method in scalar.c already has
this idempotent nature built in as an expectation since it returns zero
when the scalar.repo list already has the proper containment of the
repository.
The previous change added the 'git maintenance unregister --force'
option, so use it within 'scalar unregister' to make it idempotent.

Move 'scalar' out of 'contrib/' and into the root of the Git tree. The goal
of this change is to build 'scalar' as part of the standard Git build &
install processes.
This patch includes both the physical move of Scalar's files out of
'contrib/' ('scalar.c', 'scalar.txt', and 't9xxx-scalar.sh'), and the
changes to the build definitions in 'Makefile' and 'CMakelists.txt' to
accommodate the new program.
At a high level, Scalar is built so that:
- there is a 'scalar-objs' target (similar to those created in 029bac01a8
(Makefile: add {program,xdiff,test,git,fuzz}-objs & objects targets,
2021-02-23)) for debugging purposes.
- it appears in the root of the install directory (rather than the
gitexecdir).
- it is included in the 'bin-wrappers/' directory for use in tests.
- it receives a platform-specific executable suffix (e.g., '.exe'), if
applicable.
- 'scalar.txt' is installed as 'man1' documentation.
- the 'clean' target removes the 'scalar' executable.
Additionally, update the root level '.gitignore' file to ignore the Scalar
executable.
