An application that has been shut down is still marked as registered
even if its implementation has been already destroyed.
This may lead to unguarded crashes when calling functions that have
assumptions for being used with registered applications.
So, when an application is registered, mark it as unregistered just
before destroying its implementation and after being shut down, so that
we follow the registration process in reversed order.

Calling `dlopen()` with `libutil.so` makes the installed tests depend on

These test all the functionality and combinations of flags I can think
of. They do not cover dynamic behaviour (for example, what would happen

Signed-off-by: Philip Withnall <pwithnall@endlessos.org>
The `G_FILE_CREATE_REPLACE_DESTINATION` flag is equivalent to unlinking
the destination file and re-creating it from scratch. That did
previously work, but in the process the code would call `open(O_CREAT)`
on the file. If the file was a dangling symlink, this would create the
destination file (empty). That’s not an intended side-effect, and has
security implications if the symlink is controlled by a lower-privileged
process.
Fix that by not opening the destination file if it’s a symlink, and
adjusting the rest of the code to cope with
- the fact that `fd == -1` is not an error iff `is_symlink` is true,
- and that `original_stat` will contain the `lstat()` results for the
symlink now, rather than the `stat()` results for its target (again,
iff `is_symlink` is true).
This means that the target of the dangling symlink is no longer created,
which was the bug. The symlink itself continues to be replaced (as
before) with the new file — this is the intended behaviour of
`g_file_replace()`.
The behaviour for non-symlink cases, or cases where the symlink was not
dangling, should be unchanged.
Includes a unit test.

It’s not feasible to test that the require-same-user flag can cause
authentication to fail, as that would require the build environment to
have two users available. We can, however, test that it passes when
authenticating a client and server running under the same user account.
I have manually tested that the new flag works, by running the following
as user A:
```
`$prefix/gdbus-daemon --print-env &`
gdbus call --session --dest org.freedesktop.DBus --object-path /org/freedesktop/DBus --method org.freedesktop.DBus.ListNames
```
And then running the `gdbus call` command again as user B (with the same
value for `DBUS_SESSION_BUS_ADDRESS` in the environment), which
produces:
```
Error connecting: Unexpected lack of content trying to read a line
```
(an authentication rejection)
Commenting out the use of
`G_DBUS_SERVER_FLAGS_AUTHENTICATION_REQUIRE_SAME_USER` from
`gdbusdaemon.c`, the `gdbus call` command succeeds for both users.

The GDBusConnectionFlags and GDBusServerFlags can affect how we carry

Split out XDG_CURRENT_DESKTOP handling to a separate function and make

- When querying a TCP socket, getsockopt() may succeed but the resulting
`optlen` will be zero. This means we'd previously be reading
uninitialized stack memory in such cases.
- After a file-descriptor has gone through FD-passing, getsockopt() may
fail with EINVAL. At least this is the case with TCP sockets.
- While at it also use SOL_LOCAL instead of hard-coding its value.

These tests were originally written using the output directly from a
fuzzer which had triggered the bugs we’re testing for. However, that
means they’re liable to no longer test what they’re intended to test if
the `GDBusMessage` parsing code is changed to (for example) check for
certain errors earlier in future.
It’s better to only have one invalidity in each binary blob, so change
the test messages to all be valid apart from the specific thing they’re
testing for.
The changes were based on reading the D-Bus specification directly:
https://dbus.freedesktop.org/doc/dbus-specification.html
During these changes I found one problem in
`test_message_parse_deep_header_nesting()` where it wasn’t actually
nesting variants in the header deeply enough to trigger the bug it was
supposed to be testing for. Fixed that.

This incidentally also exercises the intended pattern for sending fds in
a D-Bus message: the fd list is meant to contain exactly those fds that
are referenced by a handle (type 'h') in the body of the message, with
numeric handle value n corresponding to g_unix_fd_list_peek_fds(...)[n].
Being able to send and receive file descriptors that are not referenced by
a handle (as in OpenFile here) is a quirk of the GDBus API, and while it's
entirely possible in the wire protocol, other D-Bus implementations like
libdbus and sd-bus typically don't provide APIs that make this possible.

This test ensures that g_socket_client_connect_to_host_async() fails if

Milan to avoid the crash, but not enough for our CI, so let's move the
cancellation to a GSocketClientEvent callback where the timing is

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.

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.
