Previously, the code validated that child objects have a path with the
object manager strictly as a prefix. That doesn’t work in the case where
the object manager’s path is `/`. This case is not recommended, but is
supported.
If the object manager’s path is `/`, validate that child objects’ paths
are not equal to it. If they are equal to it, warn the user rather than
emitting a critical warning, since we can’t expect any users who’ve not
been compliant with the spec to instantly rework their D-Bus APIs.

0.2 was just tagged, which includes a commit from 2018 that fixes a
meson warning which caused the project to fail to build on Windows with
--fatal-meson-warnings enabled.
Emit this when we're about to spawn or DBus activate a GAppInfo. This
allows lauchers to keep the appinfo associated with a startup id.
We use a GVariant to allow for future exansion of the supplied data.
When using g_desktop_app_info_launch_uris_as_manager the "launched"
signal allows to map a desktop-startup-id to a GAppInfo. Make this
possible for DBus activation too.
Since we don't have a PID there we pass a 0. Update the signal
description accordingly.
These should be implemented by loadable IO module libraries, but are not
callable in GLib itself.

This is a partial revert of commit
f378352051, as the previous commits have
silenced the AddressSanitizer warnings for `GContentType`.

Fixes: #2310
These just wrap the `__lsan_enable()` and `__lsan_disable()` functions
from the AddressSanitizer client API. They’re useful in situations where
the intended-to-be-leaked memory is being allocated in third-party code,
such as xdgmime. We can’t patch that code to call `g_ignore_leak()`.

The function pointer casts silence the compiler and allow the code to
build (and even run in the typical case). However, when building with
control flow integrity checks, the runtime (rightfully) complains about
calling a function via a mismatched function pointer type.
In order to make xdgmime properly relocatable so that unit tests can use
it without it reading and modifying the user’s actual xdgmime files, and
without the need to call setenv() (and get tied up with thread safety
problems), add a xdg_mime_set_dirs() method to allow the dirs to be
overridden. They will still default to the values of $XDG_DATA_HOME and
$XDG_DATA_DIRS.

Allocate an empty cache object, check cache objects for being empty
before using them.
Otherwise the code will re-read cache every 5 seconds, as NULL cache
does not trigger the code that stores mtime, which makes the cache
file appear modified/unloaded permanently.

Since returning exactly one match has special significance, don't
give up matching before we've found at least 2 types. Also, make
sure that we don't return the same mime type more than once.
Bug 541236.
If an `InterfacesRemoved` signal is received for an object which doesn’t
exist in the local map of interfaces, don’t emit a warning.
This seems to happen in the real world (see #2401). Without a trace of
the D-Bus traffic it’s not possible to know exactly what situation is
causing this, but it seems possible that the peer could disappear and
its `notify::name-owner` signal could be processed before its
`InterfacesRemoved` signal, or something similar.

Provide built DLLs as Gitlab-CI artifacts
To be clear, these are for testing purposes, and are not
supported releases.
See merge request GNOME/glib!2261
g_get_user_database_entry() capitalises the first letter of pw_name
with g_ascii_toupper (pw->pw_name[0]).
However, the manpage for getpwnam() and getpwuid() says the result of
those calls "may point to a static area". GLib is then trying to edit
static memory which belongs to a shared library, so segfaults.
The reentrant variants of the above calls are supposed to fill the user
buffer supplied to them, however Michael Catanzaro also found a bug in
systemd where the data is not copied to the user buffer and still points
to static memory, resulting in the same sort of segfault. See:
https://github.com/systemd/systemd/issues/20679
Solve both these cases in GLib by copying pw_name off to a temporary
variable, set uppercase on that variable, and use the variable to join
into the desired string. Free the variable after it is no longer needed.
