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
discussion seemed to peter out:

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.

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.

It’s reasonable for the `main()` function in a test suite to pass
ownership of some test data to `g_test_add_data_func_full()`, along with
a `GDestroyNotify`, and rely on GTest to free the data after all tests
have been run.
Unfortunately that only worked if the test was run, and not skipped
before its test function was called. This could happen if, for example,
it had `/subprocess` in its path.
Fix that by always freeing the test data. This required reworking how
tests are skipped, slightly, to bring all the logic for that within
`test_case_run()`, so that it could always handle the memory management.

It’s more helpful to always register the test, even if it’s normally
skipped, since then the skip is recorded in the test logs so people can
see what’s ‘missing’ from them.

The function arguments index_ and length could lead to a sum which is
larger than G_MAXUINT, possibly leading to out of boundary accesses

It's not obvious why we wouldn't use g_quark_try_string(). Add a code
comment that this is intentional and a reference for how to find out
more.
Also, fix typo in another code comment.
So that it matches `gi_arg_info_get_type_info()`. We can’t use
`gi_arg_info_get_type()` because that collides with the `GType` getter
for the type.

The amount of used memory should stay in relation to the number of
entries we have. If we delete most (75%) of the entries, let's also
reallocate the buffer down to 50% of its size.
datalist_append() now starts with 2 elements. This works together with
the shrinking. If we only have one entry left, we will shrink the buffer
back to size 2. In general, d->alloc is always a power of two (unless it
overflows after G_MAXUINT32/2, which we assume will never happen).
The previous buffer growth strategy of never shrinking is not
necessarily bad. It has the advantage to not require any checks for
shrinking, and it works well in cases where the amount of data actually
does not shrink (as we'd often expect).
Also, it's questionable what a realloc() to a smaller size really
brings. Is that really gonna help and will the allocator do something
useful?
Anyway. This patch introduces shrinking. The check for whether to shrink
changes from `if (d->len == 0)` to `if (d->len <= d->alloc / 4u)`, which
is probably cheap even if most of the time we don't need to shrink. For
most cases, that's the only change that this patch brings. However, once
we find out that 75% of the buffer are empty, calling realloc() seems a
sensible thing to do.
GI_IS_REGISTERED_TYPE_INFO() wasn't working because it was actually
defined to be the same as GI_IS_OBJECT_INFO().
Add some desultory type-checking assertions to the repository tests.
gi_repository_enumerate_versions() was missing a type check of the
instance parameter. This helps catch mistakes when porting from
girepository 1.x where the parameter was allowed to be null.
Memory was leaking when allocating it inside libelf and losing the pointer to it (it was an automatic variable) when returning NULL from the get_elf function in some cases

The main point here is to reuse datalist_remove() and datalist_shrink().
Especially, datalist_shrink() will become more interesting next, when it
actually shrinks the buffer.
Also, I find the previous implementation with "data_end" confusing.
Instead, only use index "i_data" to iterate over the data.
Extract helper functions datalist_remove() and datalist_shrink(). This
is to reduce duplicate code, but also to have a default way how to do
this.
In particular, later datalist_shrink() might do more aggressive
shrinking. We need to have that code in one place.
g_datalist_unlock() is probably faster than g_datalist_unlock_and_set().
Move the "if (data)" check (that we anyway had) earlier, so we can
call g_datalist_unlock() and return early.
If too many keys are requested, they temporary buffer is allocated
on the heap. There is no problem in principle, to remove more than
16 keys.
Well, the problem is that GData tracks entries in a linear list, so
performance will degrade when it grows too much. That is a problem,
and users should be careful to not add unreasonably many keys. But it's
not the task of g_datalist_id_remove_multiple() to decide what is
reasonable.
This limitation was present from the beginning, in commit 0415bf9412
('Add g_datalist_id_remove_multiple'). It's no longer necessary since
commit eada6be364 ('gdataset: cleanup g_data_remove_internal()').
