Even if we get warnings from the first lint check, we probably want to
see the warnings from later lint checks too, to reduce the number of
round-trips.

This will make it easier and more obvious for developers to run them
locally: I'm sure I'm not the only developer who had assumed that
`.gitlab-ci/` is private to the CI environment and inappropriate (or
perhaps even destructive) to run on a developer/user system.
The lint checks are automatically skipped (with TAP SKIP syntax) if we
are not in a git checkout, or if git or the lint tool is missing. They
can also be disabled explicitly with `meson test --no-suite=lint`,
which downstream distributions will probably want to do.
By default, most lint checks are reported as an "expected failure"
(with TAP TODO syntax) rather than a hard failure, because they do not
indicate a functional problem with GLib and there is a tendency for
lint tools to introduce additional checks or become more strict over
time. Developers can override this by configuring with `-Dwerror=true`
(which also makes compiler warnings into fatal errors), or by running
the test suite like `LINT_WARNINGS_ARE_ERRORS=1 meson test --suite=lint`.
One exception to this is tests/check-missing-install-tag.py, which is
checking a functionally significant feature of our build system, and
seems like it is unlikely to have false positives: if that one fails,
it is reported as a hard failure.
run-style-check-diff.sh and run-check-todos.sh are not currently given
this treatment, because they require search-common-ancestor.sh, which
uses Gitlab-CI-specific information to find out which commits are in-scope
for checking.

This is needed because `GITypelib` is exposed in the public
libgirepository API, so needs to be introspectable.
This should fix a couple of warnings about `gi_repository_require()` and
related APIs not being introspectable as they return an unintrospectable
type.

Since `GITypelib` is exposed in the public libgirepository API, it needs
to be a boxed type. So we either need to add a `copy` method to mirror
the existing `free` method, or switch to refcounting. The latter option
seems better, since a `GITypelib` contains internal state about open
`GModule`s and the semantics for copying that would be potentially
complex.

This makes them consistent with the other getter methods in
`GIRepository` which return lists/arrays. It’s useful to return the
length, as that means the caller doesn’t have to work it out by
iterating over the entire array.

Since they are copylibs, we don’t want to diverge from upstream by
adding SPDX lines to all the files, so add them to the dep5 file
instead.
gnulib discussed adding them upstream a couple of years ago but the

This is another way to get the file system type from `statvfs()`, newly
added in glibc 2.39
(https://lwn.net/ml/libc-alpha/38790850.J2Yia2DhmK@pinacolada/).
This hasn’t been tested with glibc 2.39 as I don’t have it, but the
change seems fairly straightforward.

It’s not suitable to use to check if your own code has already called
`g_task_return_*()`, as it doesn’t directly correlate to that.

Otherwise we would generate a multiple-inclusion guard of the
form `#ifndef __STDOUT__ ...`, which can only work for one D-Bus
interface per translation unit.

If we're writing the body to standard output, we cannot know what the
filename of the corresponding header is going to be, but it seems
vanishingly unlikely that it will be either `stdout.h` (which we would
traditionally have generated) or `-.h` (which we would have generated
since !3886).
This makes some of the output snippets sufficiently short that black(1)
requires that they are folded into a single line.

This effectively reverts commit 0910e2f6ad. I thought that `GIInfoType`
was decoupled from `GITypelibBlobType`, but it turns out that
`girepository.c` calls `gi_info_new_full()` with blob types, implicitly
converting them to info types.
This was causing anything with a type higher than the `INVALID_0` value
to be loaded as the wrong type.

Otherwise there’s no obvious suitable return value to return when the
union is *not* discriminated.
This is an API break, but libgirepository has not been in a stable
release yet, so that’s fine.

In command-line tools, ordinary filenames normally do not have
special-cased meanings, so commit 3ef742eb "Don't skip dbus-codegen tests
on Win32" was a command-line API break: in the unlikely event that a
user wanted to write to a file named exactly `stdout`, this would have
been an incompatible change.
There is a conventional pseudo-filename to represent standard output,
which is `-` (for example `cat -` is a no-op filter). Adding support
for this is technically also a command-line API break (in the very
unlikely event that a user wants to write to a file named exactly `-`,
they would now have to write it as `./-`), but filenames starting with
a dash often require special treatment anyway, so this probably will not
come as a surprise to anyone.
When the output filename is `-` we don't want to use `#ifdef _____` as
a header guard, so special-case it as `__STDOUT__` as before.
