it will load the input as a keyfile for checking its existence
and its validity (as a keyfile).
File arguments are allowed after the desktop file.

It’s possible that the variables here are only marked as volatile
because they’re arguments to `g_once_*()`. Those arguments will be
modified in a subsequent commit.

This function returns the most specific instantiatable type
that is a prerequisite for a given interface.
This type is necessary in particular when dealing with GValues
because a GValue contains an instance of a type.
This commit includes tests for the new API.
Rather than using a mixture of ‘instantiable’ and ‘instantiatable’
everywhere, standardise on the term which is already in the public API.

For legacy reasons, Meson's gtk-doc helper script launches the
gtkdoc-mkhtml tool in the `html` directory under the build root. This
means that all paths must be relative to that location.
g_has_typeof macro is wrongly in the public g_ namespace, internaly
symbols are usually in the glib_ namespace. This will also allow to
define glib_typeof differently on non-GNUC compilers (e.g. c++11
decltype).
GLib uses NULL-terminated string arrays (GStrv) in a number of places, however
these are quite hard to construct in C when the number of elements is not known
in advance. GStrvBuilder wraps GPtrArray to make these easy to create with
type safety and does the memory management for you.
By default, when using g_subprocess_launcher_take_fd() to pass an
FD to a child, the GSubprocessLauncher object also takes ownership
of the FD in the parent, and closes it during finalize(). This is
a reasonable assumption in the majority of the cases, but sometimes
it isn't a good idea.
An example is when creating a GSubprocessLauncher in JavaScript:
here, the destruction process is managed by the Garbage Collector,
which means that those sockets will remain opened for some time
after all the references to the object has been droped. This means
that it could be not possible to detect when the child has closed
that same FD, because in order to make that work, both FDs
instances (the one in the parent and the one in the children) must
be closed. This can be a problem in, as an example, a process that
launches a child that communicates with Wayland using an specific
socket (like when using the new API MetaWaylandClient).
Of course, it isn't a valid solution to manually call close() in
the parent process just after the call to spawn(), because the FD
number could be reused in the time between it is manually closed,
and when the object is destroyed and closes again that FD. If that
happens, it will close an incorrect FD.
One solution could be to call run_dispose() from Javascript on the
GSubprocessLauncher object, to force freeing the resources.
Unfortunately, the current code frees them in the finalize()
method, not in dispose() (this is fixed in !1670 (merged) ) but it
isn't a very elegant solution.
This proposal adds a new method, g_subprocess_launcher_close(),
that allows to close the FDs passed to the child. To avoid problems,
after closing an FD with this method, no more spawns are allowed.

This allows programs that want to change how log messages are printed,
such as gnome-terminal (gnome-terminal#42) and Flatpak, to override
the log-writer or the legacy log-handler without having to reimplement
the G_MESSAGES_DEBUG filtering logic.

GLib code normally prints info and debug messages to stdout,
but that interferes with programs that are documented to produce
machine-readable output such as JSON or XML on stdout. In particular,
if such a program uses a GLib-based library, setting G_MESSAGES_DEBUG
will typically result in that library's debug messages going to the
program's stdout and corrupting the machine-readable output.
Unix programs can avoid this by using dup2() to move the original stdout
to another fd, then dup2() again to make the new stdout a copy of stderr,
but it's easier if we provide a way to not write debug messages to
stdout in the first place. Calling
g_log_writer_default_set_use_stderr (TRUE) results in behaviour
resembling Python's logging.basicConfig(), with all diagnostics going
to stderr.

The basic API that this commit adds allows in-order iterating over a GTree.
For this the following API were implemented or exported:
1) Returning the first or the last node in the tree,
2) Taking a pointer to a node in the tree and returning the previous or the
next in-order node,
3) Allowing to do a binary search for a particular key value and returning
the pointer to its node,
4) Returning the newly inserted or set node from both insert and replace
functions, so this node is immediately available and does not have to be
looked up,
5) Traversing the tree in-order providing a node pointer to the
caller-provided traversal function.
Most of the above functions were already present in the code, but they
returned the value that is stored at a particular node instead of the
pointer to the node itself.
So most of the code for these new API calls is shared with these existing
ones, just adapted to return the pointer to the node.
Additionally, the so called "lower bound" and "upper bound" operations
were implemented.
The first one returns the first element that is greater than or equal to
the searched key, while the second returns the first element that is
strictly greater than the searched key.

Expose a function that prepares an attribute query string to be passed
to g_file_query_info() to get a list of attributes normally copied with
the file. This function is used by the implementation of
g_file_copy_attributes, and it's useful if one needs to split
g_file_copy_attributes into two stages, for example, when nautilus does
a recursive move of a directory. When files are moved from the source
directory, its modification time changes. To preserve the mtime on the
destination directory, it has to be queried before moving files and set
after doing it, hence these two stages.

Like G_SOURCE_REMOVE and G_SOURCE_CONTINUE, these make it clearer what
it means to return TRUE or FALSE.
In particular, in GDBus methods that fail, the failure case still needs
to return TRUE (unlike the typical GError pattern), leading to comments
like this:
g_dbus_method_invocation_return_error (invocation, ...);
return TRUE; /* handled */
which can now be replaced by:
g_dbus_method_invocation_return_error (invocation, ...);
return G_DUS_METHOD_INVOCATION_HANDLED;
G_DBUS_METHOD_INVOCATION_UNHANDLED is added for symmetry, but is very
rarely (perhaps never?) useful in practice.

There is already g_unix_mount_at function which allows to find certain
unix mount for given mount path. It would be useful to have similar
function for mount points, which will allow to replace custom codes in
gvfs. Let's add g_unix_mount_point_at.
This is a new version of the g_file_set_contents() API which will allow
its safety to be controlled by some flags, allowing the user to choose
their preferred tradeoff between safety (`fsync()` calls) and speed.
Currently, the flags do nothing and the new API behaves like the old
API. This will change in the following commits.

Add some internal wrappers around sysprof tracing, so that it can be
used throughout GLib without exposing all the details of sysprof
internally.
This adds an optional dependency on `libsysprof-capture-4`. sysprof
support is disabled without it.
This depends on the GLib dependency of `libsysprof-capture` being
dropped in https://gitlab.gnome.org/GNOME/sysprof/-/merge_requests/30,
which has bumped the soname of `libsysprof-capture` and added subproject
support.
The next few commits will add marks that trace out each `GMainContext`
iteration and each `GSource` `check`/`prepare`/`dispatch` call.

This was mostly machine generated with the following command:
```
codespell \
--builtin clear,rare,usage \
--skip './po/*' --skip './.git/*' --skip './NEWS*' \
--write-changes .
```
using the latest git version of `codespell` as per [these
instructions](https://github.com/codespell-project/codespell#user-content-updating).
Then I manually checked each change using `git add -p`, made a few
manual fixups and dropped a load of incorrect changes.
There are still some outdated or loaded terms used in GLib, mostly to do
with git branch terminology. They will need to be changed later as part
of a wider migration of git terminology.
If I’ve missed anything, please file an issue!
