Merge the topics that have been cooking since 2024-09-13 or so in
'next'.
Let's try a new workflow to update the maintenance track by removing
the "merge ... later to maint" comments from the draft release notes
on the 'master' track.

--ours, --theirs, and --union are already supported in `git merge-file`
for automatically resolving conflicts in favor of one version or the
other, instead of leaving conflict markers in the file. Support them in
`git apply -3` as well because the two commands do the same kind of
file-level merges.
In case in the future --ours, --theirs, and --union gain a meaning
outside of three-way-merges, they do not imply --3way but rather must be
specified alongside it.

Back when 7cc91a2f (Add the configuration option skipFetchAll,
2009-11-09) added for the sole purpose of adding skipFetchAll as a
synonym to skipDefaultUpdate, there was no explanation about the
reason why it was needed., but these two configuration variables
mean exactly the same thing.
Also, when we taught the "prefetch" task to "git maintenance" later,
we did make it pay attention to the setting, but we forgot to
document it.
Document these variables as synonyms that collectively implements
the last-one-wins semantics, and also clarify that the prefetch task
is also controlled by this variable.

The GIT_ADVICE environment variable was added implicitly in b79deeb554
(advice: add --no-advice global option, 2024-05-03) but was not
documented. Add documentation to show that it is an option for tools
that want to disable these messages. Make note that while the
--no-advice option exists, older Git versions will fail to parse that
option. The environment variable presents a way to change the behavior
of Git versions that understand it without disrupting older versions.

Some large repositories use tags to track a huge list of release
versions. While this choice is costly on the ref advertisement, it is
further wasteful for clients who do not need those tags. Allow clients
to optionally skip the tag advertisement.
This behavior is similar to that of 'git clone --no-tags' implemented in
0dab2468ee (clone: add a --no-tags option to clone without tags,
2017-04-26), including the modification of the remote.origin.tagOpt
config value to include "--no-tags".
One thing that is opposite of the 'git clone' implementation is that
this allows '--tags' as an assumed option, which can be naturally negated
with '--no-tags'. The clone command does not accept '--tags' but allows
"--no-no-tags" as the negation of its '--no-tags' option.
While testing this option, combine the test with the previously untested
'--no-src' option introduced in 4527db8ff8 (scalar: add --[no-]src
option, 2023-08-28).

Our unit testing framework is a homegrown solution. While it supports
most of our needs, it is likely that the volume of unit tests will grow
quite a bit in the future such that we can exercise low-level subsystems
directly. This surfaces several shortcomings that the current solution
has:
- There is no way to run only one specific tests. While some of our
unit tests wire this up manually, others don't. In general, it
requires quite a bit of boilerplate to get this set up correctly.
- Failures do not cause a test to stop execution directly. Instead,
the test author needs to return manually whenever an assertion
fails. This is rather verbose and is not done correctly in most of
our unit tests.
- Wiring up a new testcase requires both implementing the test
function and calling it in the respective test suite's main
function, which is creating code duplication.
We can of course fix all of these issues ourselves, but that feels
rather pointless when there are already so many unit testing frameworks
out there that have those features.
We line out some requirements for any unit testing framework in
"Documentation/technical/unit-tests.txt". The "clar" unit testing
framework, which isn't listed in that table yet, ticks many of the
boxes:
- It is licensed under ISC, which is compatible.
- It is easily vendorable because it is rather tiny at around 1200
lines of code.
- It is easily hackable due to the same reason.
- It has TAP support.
- It has skippable tests.
- It preprocesses test files in order to extract test functions, which
then get wired up automatically.
While it's not perfect, the fact that clar originates from the libgit2
project means that it should be rather easy for us to collaborate with
upstream to plug any gaps.
Import the clar unit testing framework at commit 1516124 (Merge pull
request #97 from pks-t/pks-whitespace-fixes, 2024-08-15). The framework
will be wired up in subsequent commits.

The git-pack-redundant(1) command is already in the process of being
phased out and dies unless the user passes the `--i-still-use-this` flag
since 4406522b76 (pack-redundant: escalate deprecation warning to an
error, 2023-03-23). We haven't heard any complaints, so let's announce
the removal of this command in Git 3.0 in our breaking changes document.
