The compat/ directory contains many stub functions, wrappers, and so on
that have to conform to a specific interface, but don't necessarily need
to use all of their parameters. Let's mark them to avoid complaints from
-Wunused-parameter.
This was done mostly via guess-and-check with the Windows build in
GitHub CI. I also confirmed that the win+VS build is similarly happy.

As with the files touched in the previous commit, win32/headless.c does
not include git-compat-util.h, so it doesn't have our UNUSED macro.
Unlike those ones, this is not third-party code, so it would not be a
big deal to modify it.
However, I'm not sure if including git-compat-util.h would create other
headaches (and I don't even have a machine to test this on; I'm relying
on Windows CI to compile it at all). Given how trivial the file is, and
that the unused parameters are not interesting (they are just
boilerplate for the wWinMain() function), we can just use the same trick
as the previous commit and disable the warnings via pragma.

We carry some vendored 3rd-party code in compat/ that does not build
cleanly with -Wunused-parameters. We could mark these with UNUSED, but
there are two reasons not to:
1. This is code imported from elsewhere, so we'd prefer to avoid
modifying it in an invasive way that could create conflicts if we
tried to pull in a new version.
2. These files don't include git-compat-util.h at all, so we'd need to
factor out (or repeat) our UNUSED macro.
In theory we could modify the build process to invoke the compiler with
the extra warning disabled for these files, but there are tricky corner
cases there (e.g., for NO_REGEX we cannot assume that the compiler
understands -Wno-unused-parameter as an option, so we'd have to use our
detect-compiler script).
Instead, let's rely on the gcc diagnostic #pragma. This is horribly
unportable, of course, but it should do what we want. Compilers which
don't understand this particular pragma should ignore it (per the
standard), and compilers which do care about "-Wunused-parameter" will
hopefully respect it, even if they are not gcc (e.g., clang does).

The "loose-objects" maintenance tasks executes git-pack-objects(1) to
pack all loose objects into a new packfile. This command ends up
printing the hash of the packfile to stdout though, which clutters the
output of `git maintenance run`.
Fix this issue by disabling stdout of the child process.

In t7900, we exercise the `--detach` logic by checking whether the
command ended up writing anything to its output or not. This supposedly
works because we close stdin, stdout and stderr when daemonizing. But
one, it breaks on platforms where daemonize is a no-op, like Windows.
And second, that git-maintenance(1) outputs anything at all in these
tests is a bug in the first place that we'll fix in a subsequent commit.
Introduce a new trace2 region around the detach which allows us to more
explicitly check whether the detaching logic was executed. This is a
much more direct way to exercise the logic, provides a potentially
useful signal to tracing logs and also works alright on platforms which
do not have the ability to daemonize.

As we have operated with "write like how your surrounding code is
written" for too long, after a huge code drop from another project,
we'll end up being inconsistent before such an imported code is
cleaned up. We have many uses of cast operator with a space before
its operand, mostly in the reftable code.
Spell the convention out before it spreads to other places.

Commit f24a9b78a9 (t-hashmap: mark unused parameters in callback
function, 2024-08-17) noted that the t_intern() does not need its
hashmap parameter, but we have to keep it to conform to the function
pointer interface of setup().
But since the only thing setup() does is create and tear down the
hashmap, we can just skip calling setup() entirely for this case, and
drop the unused parameters. This simplifies the code a bit.
