If the directory is overridden, for example when running tests, the
parent directory of `.dbus-keyrings` (i.e. the fake `$HOME` directory)
might not exist. Create it automatically.
This should realistically not have an effect on non-test code.

These can be hit in the tests (if multiple tests run in parallel are
racing for `~/.dbus-keyrings/org_gtk_gdbus_general.lock` for a prolonged
period) and will cause spurious test failures due to the use of
`G_DEBUG=fatal-warnings`.
Instead, allow the error messages to be inspected programmatically.

The compiler can’t work out from the combination of other conditions
that it’s not possible for (m2 == NULL) to hold true when memcmp() is
called, so add an explicit condition.

Otherwise we’ll end up using the host’s `objcopy`, which will output
object files in the wrong format.

Previously, these GTimeZone objects were being cached in the `time_zones` cache, but dropped from it when their final ref was dropped (which was frequently). That meant additional reads of `/etc/localtime` next time they were created, which was noticeable on profiles. Keep a permanent ref to the UTC and local timezones.
glibc declares memcpy() with the first two arguments (the pointers)
annotated as non-null via an attribute, which results in the undefined
behaviour sanitizer considering it to be UB to pass a null pointer
in the second argument, even if we are copying 0 bytes (and hence not
actually dereferencing the pointer).
This shows up in array-test when run with the undefined behaviour
sanitizer.

Note that I deliberately haven't used g_autoptr here, because while we
encourage GLib users to use g_autoptr in their own code, GLib itself
still supports being compiled in environments like MSVC that can't
support g_autoptr.

The user_data for g_ptr_array_sort_with_data is passed directly, not
with an extra layer of pointer like the data pointers.

This is like `GMutexLocker`, in that if you are able to use
`g_autoptr()`, it makes popping a `GMainContext` off the thread-default
main context stack easier when exiting a function.
A few uses of `G_GNUC_{BEGIN,END}_IGNORE_DEPRECATIONS` are needed to
avoid warnings when building apps against GLib with
`GLIB_VERSION_MAX_ALLOWED < GLIB_VERSION_2_64`.

We may need to declare autocleanups for new types, which will be marked
as ‘deprecated’ if the code which includes GLib doesn’t declare a high
enough `GLIB_VERSION_MAX_ALLOWED`. Despite that, we still need to
declare the autocleanups.

The token parsing done by g_variant_parse() uses recursive function
calls, so at some point it will hit the stack limit. As with previous
changes to `GVariantType` parsing (commit 7c4e6e9fbe), limit the level
of nesting of containers parsed by g_variant_parse() to something
reasonable. We guarantee 64 levels of nesting, which should be enough
for anyone, and is the same as what we guarantee for types.

On closer reading of `man 3 timezone`, it’s actually permissible for
`TZ` to contain an absolute path which points to a tzfile file outside
the system time zone database. This is indeed what happens when building
GLib under Fedora’s toolbox, so relax that check in the tests.

There are a lot of Unix-like systems which have not implemented the
os-release spec. On such system, we can use POSIX uname function as a
fallback to get basic information of the system.
/etc/os-release is a spec designed for Linux. While other OSes can
implement it, it doesn't make sense to use Linux as the default value
on systems which don't use Linux.
Previously we were keeping a pointer to the `GFileMonitor` in a
`GFileMonitorSource` instance, but since we weren’t keeping a strong
reference, that `GFileMonitor` instance could be finalised from another
thread at any point while the source was referring to it. Not good.
Use a weak reference, and upgrade it to a strong reference whenever the
`GFileMonitorSource` is referring to the file monitor.

It’s not enough to unref the monitor, since the GLib worker thread might
still hold a reference to it.

`DesktopFileDir` pointers are passed around between threads: they are
initially created on the main thread, but a pointer to them is passed to
the GLib worker thread in the file monitor callback
(`desktop_file_dir_changed()`).
Accordingly, the `DesktopFileDir` objects either have to be
(1) immutable;
(2) reference counted; or
(3) synchronised between the two threads
to avoid one of them being used by one thread after being freed on
another. Option (1) changed with commit 99bc33b6 and is no longer an
option. Option (3) would mean blocking the main thread on the worker
thread, which would be hard to achieve and is against the point of
having a worker thread. So that leaves option (2), which is implemented
here.

Most of the info returned is static, the only thing that changes
is the OS version.
This code relies on g_win32_check_windows_version() providing
accurate information (hopefully, MS won't nix RtlGetVersion() on
which we use for that) and supplements it with information from the
registry for Windows >= 8.1.
