This makes the code a little easier to understand and allows the kernel
a little bit more leeway in scheduling the callback, which is fine
because we don’t need high accuracy here.

`g_notification_backend_new_default()` adds a reference on
`backend->dbus_connection` (if non-`NULL`), but nothing ever unreffed
that.
Fix that by adding a dispose method.
In practice this is not really a problem, because the notification
backend is held alive by a `GApplication`, which lives as long as the
process. It’ll be a problem if someone is to ever add unit tests for
`GNotificationBackend`s though. So let’s fix it.

Add a few missing introspection annotations too.
This doesn’t change any of the ownership handling behaviour, just
documents what’s there. What’s there seems to be correct, to the extent
that I can see.

The code is correct, but from a quick read-through it wasn’t entirely
clear to me how it handled floating `GVariant`s in object state or the
`parameter` argument.
Add an assertion and some comments to hopefully clarify things a little.

Do not use can_run_host_binaries() as it returns true even though
custom_target() does not currently correctly wrap target-built
tool binaries with exe_wrapper so they can be run on the host.

Otherwise this test will succeed at build-time, but will fail when run
as an as-installed test via ginsttest-runner.

Building GLib 2.75.0 on Linux adds various inotify-related internal
symbols to the ABI, which doesn't seem to have been intentional.
I went through the other libraries in the build system, and it looks
as though the BSD kqueue backend would have the same problem.
GNU symbol visibility probably doesn't do anything for gio/win32, but
for completeness I've set that to use hidden symbols too, on the basis
that it'll be easier to get this right if we're consistent.

The macOS CI builds with -Werror=missing-field-initializers by default,
making incomplete initializers a compile-time error (even though their
meaning is well-defined: missing fields are initialized as if with
.field = 0).

It’s deprecated, but the big red 0/0/0 line for the `glib/gthread`

The fuzz tests are run on a separate CI system, and we don’t care what
their code coverage is. The only reason they’re run on our CI systems at
all is as a smokecheck. They are not unit tests that we want to check
are running every line.
Similarly, exclude copylibs/subprojects as GLib is not responsible for
testing them. They have (or should have) their own unit tests and code
coverage metrics in their upstreams.

This typically indicates a bug in the program, where a GTask has been
created, but a bug in the control flow has caused it to not return a
value.
There is one situation where it might be legitimate to finalise a GTask
without returning: if an error happens in your *_async() start function
after you’ve created a GTask, but before the async operation returns to
the main loop; and you report the error using g_task_report_*error()
rather than reporting it using the newly constructed GTask.
Another situation is where you are just using GTask as a convenient way
to move some work to another thread, without the complexity of creating
and running your own thread pool. GDBus does this with
g_dbus_interface_method_dispatch_helper(), for example.
In most other cases, it’s a bug. Emit a debug message about it, but not
a full-blown warning, as that would create noise in the legitimate
cases.

This can be used to mark entire types as deprecated,
and trigger a warning when they are instantiated
and `G_ENABLE_DIAGNOSTIC=1` is set in the environment.
There's currently no convenient macros for defining
types with the new flag, but you can do:
```c
_G_DEFINE_TYPE_EXTENDED_BEGIN (GtkAppChooserWidget,
gtk_app_chooser_widget,
GTK_TYPE_WIDGET,
G_TYPE_FLAG_DEPRECATED)
...
_G_DEFINE_TYPE_EXTENDED_END ()
```
Includes a unit test by Philip Withnall.
the gio dbus codegen test has 10 test cases in it.
Each test case is given 100 seconds to complete.
That is far longer than they should need.
Furthermore, the entire test is only given 60s
to complete.
This commit makes the internal timeout more consistent
with the external timeout, by giving each of the 10
test cases 6 seconds instead of 100s.
This further helps with the potential denial of service problem in
issue #2782 / oss-fuzz#49462 / oss-fuzz#20177.
Instead of allocating a new `GVariant` for each nesting level of
maybe-types, allocate a single `GVariant` and give it the fully-nested
maybe type as its type. This has to be done in serialised form.
This prevents attackers from triggering O(size of container × typedecl
depth) allocations.
This is a follow up to commit 3e313438f1,
and includes a test.

This doesn’t enforce licensing/copyright headers to be present on all
files, but does check that at least a minimum number of files are
correct.
This should help avoid new files being added without appropriate
licensing information in future.
The baseline is set at what `reuse lint` outputs for me at the moment.
See https://reuse.software/tutorial/#step-2 for information about how to
add REUSE-compliant licensing/copyright to files.

reStructuredText doesn’t support cross-references unless always built

So reword this (currently manual) cross-reference so it’s less awkward.

I believe the specification was originally a shorter extract of
Allison’s thesis. This left a few dangling references to requirements
which were listed in a part of the thesis not included in the
specification.
Reword them slightly so they’re not quite so awkward.
