When an object is revitalized and a notify callbacks increased the reference
counter of the object, we are calling the toggle notifier twice, while it
should only happen if also the actual reference count value is 1 (after
having been decremented from 2).
If an object gets revitalized during the dispose vfunc, we need to call
toggle refs notifiers only if we had 2 references and if the object has
the toggle references enabled.
This may change in case an object notifier handler changes this status,
so do this check only after we've called the notifiers so that in case
toggle notifications are enabled afterwards we still call the handlers.
We were reading if an object has toggle references even if this was not
really relevant for the current object state, as we only need to notify
when going from 2 to 1 references, so first ensure that this is the case
and then check if we have toggle references enabled in the object.
This is a micro-optimization, for the way flags are defined, but still
an operation we can avoid in most cases.
Even though the check is likely to be relevant if the object is finalized,
it may still give some indication if called while an instance has just lost
the last reference.
So use `g_return_if_fail` for consistency with the rest of the code.
In case they differ from the defaults, we probably want to ignore them
when listing filesystems which are interesting to the user.

This reworks commit 20e1508e6e, for two
reasons:
- Upstream dbus.git now does the same (although this isn’t yet reflected
in the online version of the D-Bus Specification); see
https://gitlab.freedesktop.org/dbus/dbus/-/merge_requests/209.
- It allows local-prefix (e.g. jhbuild) builds of GLib to build in a
custom prefix while still interacting with system services using the
system-wide `/run` directory. To do so, pass `-Druntime_dir=/run` to
meson configure.
As documented in the `NEWS` file in
https://gitlab.freedesktop.org/dbus/dbus/-/merge_requests/209, it’s only
valid to use `/run` – rather than `/var/run` – for D-Bus if the two
paths are interoperable. i.e. `/var/run` should be a symlink to `/run`,
and the D-Bus daemon should be configured to put its socket there.
This commit deliberately doesn’t introduce a special `system_socket`
configure option for specifying where the D-Bus system socket lives, as
that would only be useful for a distribution which sets `runstatedir` to
something other than `/var/run` or `/run`, which seems unlikely. We
could add such an option in future, though, if a distribution comes
forward with such a requirement.

https://gitlab.gnome.org/GNOME/glib/-/merge_requests/3095#note_1605502.

This will be used in upcoming commits to allow the previously-hardcoded
`/run` path to be set at configure time.
Most people will not want to change it from `/run`, even when building
test builds, as otherwise interaction with system mounts and services
will not work.
Inspired by equivalent changes in dbus.git in their commit
ff92efa389a57a5250c6996df6614234d4d462e0.

`join_paths()` automatically drops all preceding path elements if an
argument to it is an absolute path. The `/` is a tidier synonym for
`join_paths()`.
This introduces no functional changes.

The value of `wrote_bytes` will never be negative, so there’s no need to
store it in a signed type.
Add a couple of assertions to validate that it never decreases and hence
can never go negative.

under cygwin socklen_t is signed which leads to warnings like:
warning: comparison of integer expressions of different signedness:
‘long unsigned int’ and ‘socklen_t’ {aka ‘int’} [-Wsign-compare]
In both cases we compare against some small fixed sizes, so cast them
to socklen_t.
cygwin defines socklen_t as int, unlike everywhere else where it is uint32_t (afaics),
so signed vs unsigned.
The recently added -Werror=pointer-sign in 4353813058
makes the build fail under cygwin now with something like:
error: pointer targets in passing argument 5 of ‘getsockopt’ differ in signedness [-Werror=pointer-sign]
This changes guint to socklen_t where needed for getsockname, getpeername and getsockopt.
They return floating references, so that should be reflected in the
introspection annotations.

In case g_atomic_int_compare_and_exchange() check fails we ended up doing
another atomic get to figure out what it was the old reference count,
however, we can avoid this by using the full version of the function that
returns the value before the exchange happened as an out value.
In both these cases, the static analyser (Coverity) was worrying that
the array `data`/`pdata` wasn’t allocated before an element was written
to. That was a false positive: all the necessary conditions are met in
both cases for `g_{ptr_,}array_maybe_expand()` to always allocate the
array.
But it makes things a bit easier for the analyser if we add an assertion
to double-check that.

Do not search in path for snapctl to avoid it to be potentially
overridden by changing the PATH env variable.
Still allow testing by using an ifdef to check if we're building for the
test files or not.
Test all the snap cases and the unknown sandbox one.
We need to use different test processes as we initialize the portal
type early enough that it can't be changed later.
This is of particular use in the gsettings backend, which is currently using
dconf for all snaps.
Fully confined snaps should use the keyfile backend, as Flatpaks do.

Classic snaps are just a kind of packages with no sandbox at all, so
there's no point to mark them as sandboxed.
In this way we can just do IO checks once without having to multiply
them.

This reverts commit 91f14cd058.
The freedesktop SDK, which is used by gnome-build-meta, only has Meson
0.63. Bumping GLib’s Meson dependency to 0.64 means that, at the moment,
GLib is not buildable in gnome-build-meta and hence can’t be tested in
nightly pipelines against other projects, etc.
That’s bad for testing GLib.
It’s arguably bad that we’re restricted to using an older version of
Meson than shipped by Debian Testing, but that’s a separate discussion
to be had.
Revert the Meson 0.64 dependency until the freedesktop SDK ships Meson ≥
0.64. This also means reverting the simplifications to use of
`gnome.mkenum_simple()`.
