The reftable backend, sorts its updates by refname before applying them,
this ensures that the references are stored sorted. When migrating
reflogs from one backend to another, the order of the reflogs must be
maintained. Add a new `index` field to the `ref_update` struct to
facilitate this.
This field is used in the reftable backend's sort comparison function
`transaction_update_cmp`, to ensure that indexed fields maintain their
order.

The reference backends obtain the committer information from
`git_committer_info(0)` when adding a reflog. The upcoming patches
introduce support for migrating reflogs between the reference backends.
This requires an interface to creating reflogs, including custom
committer information.
Add a new field `committer_info` to the `ref_update` struct, which is
then used by the reference backends. If there is no `committer_info`
provided, the reference backends default to using
`git_committer_info(0)`. The field itself cannot be set to
`git_committer_info(0)` since the values are dynamic and must be
obtained right when the reflog is being committed.

Just like `git log`, now also `git range-diff` has that option as a
shortcut for the common operation that would otherwise require the quite
unwieldy (if theoretically "more correct") `--diff-mode=remerge` option.

The `git log` command already offers support for including diffs for
merges, via the `--diff-merges=<format>` option.
Let's add corresponding support for `git range-diff`, too. This makes it
more convenient to spot differences between commit ranges that contain
merges.
This is especially true in scenarios with non-trivial merges, i.e.
merges introducing changes other than, or in addition to, what merge ORT
would have produced. Merging a topic branch that changes a function
signature into a branch that added a caller of that function, for
example, would require the merge commit itself to adjust that caller to
the modified signature.
In my code reviews, I found the `--diff-merges=remerge` option
particularly useful.

To show a remerge diff, the merge needs to be recreated. For that to
work, the merge base(s) need to be found, which means that the commits'
parents have to be traversed until common ancestors are found (if any).
However, one optimization that hails all the way back to cb115748ec0d
(Some more memory leak avoidance, 2006-06-17) is to release the commit's
list of parents immediately after showing it _and to set that parent
list to `NULL`_. This can break the merge base computation.
This problem is most obvious when traversing the commits in reverse: In
that instance, if a parent of a merge commit has been shown as part of
the `git log` command, by the time the merge commit's diff needs to be
computed, that parent commit's list of parent commits will have been set
to `NULL` and as a result no merge base will be found (even if one
should be found).
Traversing commits in reverse is far from the only circumstance in which
this problem occurs, though. There are many avenues to traversing at
least one commit in the revision walk that will later be part of a merge
base computation, for example when not even walking any revisions in
`git show <merge1> <merge2>` where `<merge1>` is part of the commit
graph between the parents of `<merge2>`.
Another way to force a scenario where a commit is traversed before it
has to be traversed again as part of a merge base computation is to
start with two revisions (where the first one is reachable from the
second but not in a first-parent ancestry) and show the commit log with
`--topo-order` and `--first-parent`.
Let's fix this by special-casing the `remerge_diff` mode, similar to
what we did with reflogs in f35650dff6a4 (log: do not free parents when
walking reflog, 2017-07-07).

Wire up CI builds for both GitLab and GitHub that use the Meson build
system.
While the setup is mostly trivial, one gotcha is the test output
directory used to be in "t/", but now it is contained in the build
directory. To unify the logic across Makefile- and Meson-based builds we
explicitly set up the `TEST_OUTPUT_DIRECTORY` variable so that it is the
same for both build systems.

Our unit tests that don't yet use the clar unit testing framework ignore
any option that they do not understand. It is thus fine to just pass
test options we set up globally to those unit tests as they are simply
ignored. This makes our life easier because we don't have to special
case those options with Meson, where test options are set up globally
via `meson test --test-args=`.
But our clar-based unit testing framework is way stricter here and will
fail in case it is passed an unknown option. Stub out these options with
no-ops to make our life a bit easier.
Note that this also requires us to remove the `-x` short option for
`--exclude`. This is because `-x` has another meaning in our integration
tests, as it enables shell tracing. I doubt there are a lot of people
out there using it as we only got a small hand full of clar tests in the
first place. So better change it now so that we can in the long run
improve compatibility between the two different test drivers.

Both t9835 and t9836 exercise git-p4, but one exercises Python 2 whereas
the other one uses Python 3. These tests do not exercise "git p4", but
instead they use "git p4.py". This calls the unbuilt version of
"git-p4.py" that still has the "#!/usr/bin/env python" shebang, which
allows the test to modify which Python version comes first in $PATH,
making it possible to force a Python version.
But "git-p4.py" is not in our PATH during out-of-tree builds, and thus
we cannot locate "git-p4.py". The tests thus break with CMake and Meson.
Fix this by instead manually setting up script wrappers that invoke the
respective Python interpreter directly.

In the preceding commit, we have introduced consistency checks to Meson
to detect any discrepancies with missing or extraneous tests in its
build instructions. These checks only get executed in Meson though, so

All of the code files for unit tests using the self-grown unit testing
framework have a "t-" prefix to their name. This makes it easy to
identify them and use globbing in our Makefile and in other places. On
the other hand though, our clar-based unit tests have no prefix at all
and thus cannot easily be discerned from other files in the unit test
directory.
Introduce a new "u-" prefix for clar-based unit tests. This prefix will
be used in a subsequent commit to easily identify such tests.

Auto-select ("Copy commit ID to X11 selection") is useful when a
selection cliboard exists, but otherwise generally meaningless, for
instance on Windows.
Add a similar pref and behavior which copies the commit ID to the
primary clipboard - for platforms without a selection clipboard, but
which can also be useful additionally on platforms with selection.
Note that while autoselect is enabled by default, autocopy isn't.
That's because the selection clipboard is typically dispensable, while
the primary clipboard can be considered a more precious resource,
which we don't want to (clear and) overwrite by default.

Tl;DR: change Auto-select text, move the length input to a new line.
The Auto-select preference auto-selects [part of] the commit ID text
at the respective widget on startup, and when the current commit at
the graph changes.
Its real premise, however, is to populate the selection clipboard
with the commit ID. Consider, for instance, how meaningless it is on
platforms without a selection clipboard - like Windows or macOS (on
Windows the selection is not even visible with the default Tk theme,
because it's only visible in focused widgets - which the commit ID
widget is not during normal application of this selection).
So rename the Auto-select label to "Copy commit ID to X11 selection",
to reflect better the ultimate outcome of its application
Note that there exists other, non-X11 platforms with a selection
clipboard, like Wayland, and if a native Tk client exists on such
platforms, then the description will not be accurate, but hopefully
it's not too misleading either.
Additionally, move the length input widget to a new line, because:
- This length applies to both Auto-select and "Copy commit reference"
context menu item, so it's not exclusive to the selection length.
- The next commit will add support for primary clipboard as well,
where this length will also be used.
Also, move the "Hide remotes" item above these selection prefs, to
keep the selection prefs semi-grouped before the spacing of the
following title "Diff display options".

The changes in commit c06793a4ed (allow git-bundle to create bottomless
bundle, 2007-08-08) ensure annotated tags are properly preserved when
creating a bundle using a revision range operation.
At the time the range notation would peel the ends to their
corresponding commit, meaning ref v2.0 would point to the v2.0^0 commit.
So the above workaround was introduced. This code looks up the ref
before it's written to the bundle, and if the ref doesn't point to the
object we expect (for tags this would be a tag object), we skip the ref
from the bundle. Instead, when the ref is a tag that's the positive end
of the range (e.g. v2.0 from the range "v1.0..v2.0"), then that ref is
written to the bundle instead.
Later, in 895c5ba3c1 (revision: do not peel tags used in range notation,
2013-09-19), the behavior of parsing ranges was changed and the problem
was fixed at the cause. But the workaround in bundle.c was not reverted.
Now it seems this workaround can cause a race condition. git-bundle(1)
uses setup_revisions() to parse the input into `struct rev_info`. Later,
in write_bundle_refs(), it uses this info to write refs to the bundle.
As mentioned at this point each ref is looked up again and checked
whether it points to the object we expect. If not, the ref is not
written to the bundle. But, when creating a bundle in a heavy traffic
repository (a repo with many references, and frequent ref updates) it's
possible a branch ref was updated between setup_revisions() and
write_bundle_refs() and thus the extra check causes the ref to be
skipped.
The workaround was originally added to deal with tags, but the code path
also gets hit by non-tag refs, causing this race condition. Because it's
no longer needed, remove it and fix the possible race condition.

Whenever we source "ci/lib.sh" we wrap the directives in a separate
group so that they can easily be collapsed in the web UI. And as we
source the script multiple times during a single CI run we thus end up
with the same section name reused multiple times, as well.
This is broken on GitLab CI though, where reusing the same group name is
not supported. The consequence is that only the last of these sections
can be collapsed.
Fix this issue by including the name of the sourcing script in the
group's name.

When git-submodule.sh parses various options and switches, it sets some
variables to values; the variables in turn affect the options given to
git-submodule--helper.
Currently, variables which correspond to switches have boolean values
(for example, whenever "--force" is passed, force=1), while variables
which correspond to options which take arguments have string values that
sometimes contain the option name and sometimes only the option value.
Set all of the variables to strings which contain the option name (e.g.
force="--force" rather than force=1); this has a couple of advantages:
it improves consistency, readability and debuggability.

It's entirely unnecessary to check whether the argument given to an
option (i.e. --summary-limit) is valid in the shell wrapper, since it's
already done when parsing the various options in git-submodule--helper.
Remove this check from the script; this both improves consistency
throughout the script, and the error message shown to the user in case
some invalid non-numeric argument was passed to "--summary-limit" is
more informative as well.
