When f4dbdfc4d5 (commit-graph: clean up leaked memory during write,
2018-10-03) added the UNLEAK, it was right before a call to die_errno().
e103f7276f (commit-graph: return with errors during write, 2019-06-12)
made it unnecessary, as it was then followed by a free() call for the
allocated string.
The code moved to write_commit_graph_file() in the meantime and the
string pointer is now part of a struct, but the function's only caller
still cleans up the allocation. Drop the superfluous UNLEAK.

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.

When we open a repository with the "Directory" option, we use "rev-parse
--git-dir" to get the path relative to that directory, and then use
Cwd::abs_path() to make it absolute (since our process working directory
may not be the same).
These days we can just ask for "--absolute-git-dir" instead, which saves
us a little code. That option was added in Git v2.13.0 via a2f5a87626
(rev-parse: add '--absolute-git-dir' option, 2017-02-03). I don't think
we make any promises about running mismatched versions of git and
Git.pm, but even if somebody tries it, that's sufficiently old that it
should be OK.

When opening a bare repository like:
Git->repository(Directory => '/path/to/bare.git');
we will incorrectly point the repository object at the _current_
directory, not the one specified by the option.
The bug was introduced by 20da61f25f (Git.pm: trust rev-parse to find
bare repositories, 2022-10-22). Before then, we'd ask "rev-parse
--git-dir" if it was a Git repo, and if it returned anything, we'd
correctly convert that result to an absolute path using File::Spec and
Cwd::abs_path(). If it didn't, we'd guess it might be a bare repository
and find it ourselves, which was wrong (rev-parse should find even a
bare repo, and our search circumvented some of its rules).
That commit dropped most of the custom bare-repo search code in favor of
using "rev-parse --is-bare-repository" and trusting the "--git-dir" it
returned. But it mistakenly left some of the bare-repo code path in
place, which was now broken. That code calls Cwd::abs_path($dir); prior
to 20da61f25f $dir contained the "Directory" option the user passed in.
But afterwards, it contains the output of "rev-parse --git-dir". And
since our tentative rev-parse command is invoked after changing
directory, it will always be the relative path "."! So we'll end up with
the absolute path of the process's current directory, not the Directory
option the caller asked for.
So the non-bare case is correct, but the bare one is broken. Our tests
only check the non-bare one, so we didn't notice. We can fix this by
running the same absolute-path fixup code for both sides.

In the preceding commits we had to convert the linux32 job to be based
on Ubuntu 20.04 instead of Ubuntu 16.04 due to a limitation in GitHub
Workflows. This was the only job left that still tested against this old
but supported Ubuntu version, and we have no other jobs that test with a
comparatively old Linux distribution.
Add a new job to GitLab CI that tests with Ubuntu 16.04 to cover the
resulting test gap. GitLab doesn't modify Docker images in the same way
GitHub does and thus doesn't fall prey to the same issue. There are two
compatibility issues uncovered by this:
- Ubuntu 16.04 does not support HTTP/2 in Apache. We thus cannot set
`GIT_TEST_HTTPD=true`, which would otherwise cause us to fail when
Apache fails to start.
- Ubuntu 16.04 cannot use recent JGit versions as they depend on a
more recent Java runtime than we have available. We thus disable
installing any kind of optional dependencies that do not come from
the package manager.
These two restrictions are fine though, as we only really care about
whether Git compiles and runs on such old distributions in the first
place.

Building older versions of Git may require tweaking some build knobs. In
particular, very old versions of Git will fail to build with recent
OpenSSL, because the bignum type switched from a struct to a pointer.
The i5500 interop test uses Git v1.0.0 by default, which triggers this
problem. You can work around it by setting NO_OPENSSL in your
GIT_TEST_MAKE_OPTS variable. But there are two downsides:
1. You have to know to do this, and it's not at all obvious.
2. That sets the options for _all_ versions of Git that we build. And
it's possible for two versions to require conflicting knobs. E.g.,
building with "make NO_OPENSSL=Nope OPENSSL_SHA1=Yes" causes
imap-send.c to barf, because it declares a fallback typedef for SSL.
This is something we may want to fix, but of course many historical
versions are affected, and the interop scripts should be flexible
enough to build everything.
So let's introduce per-version make options, along with the ability for
scripts to specify knobs that match their default versions. That should
make everything build out of the box, but also allow testers flexibility
if they are testing interoperability between non-default versions.
We'll set NO_OPENSSL by default for v1.0.0 in i5500. It doesn't have to
worry about the conflict with OPENSSL_SHA1 because imap-send did not
exist back then (but if it did, it could also just explicitly use a
different hash implementation).
