This change aims to help populate more of the [`Certificate`][wk-cert]
info in the WebKit Inspector Protocol on Linux.
This changeset stems from work in Microsoft Playwright to [add more info
into its HAR capture][pw] generated from the Inspector Protocol events
and will bring feature parity across WebKit platforms.

Include the base URI in the `g_test_bug()` calls instead. This resolves
inconsistencies between the old bug base (bugzilla.gnome.org) and the
new bug base (gitlab.gnome.org). It also has the advantage that the URI
passed to `g_test_bug()` is now clickable in the code editor, rather
than being split across two locations.

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.

`""` is not a valid path (`stat()` on it returns `ENOENT`). Previously,
a full `GLocalFile` was being created, which ended up resolving to
`$CWD`, through path canonicalisation. That isn’t right.

Calling `dlopen()` with `libutil.so` makes the installed tests depend on
having glibc's development files installed. To avoid this, we can work
out the runtime library name at build time and `dlopen` that instead.
This approach is [taken from libfprint][1], thanks to Marco Trevisan.

`ENXIO` can be returned from `open(2)` for special files (FIFOs, device

These test all the functionality and combinations of flags I can think
of. They do not cover dynamic behaviour (for example, what would happen
if the source file is deleted by another process part-way through a call
to `g_file_replace()`).
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
out authentication and authorization, either making it more or less
restrictive, so it's desirable to "fail closed" if a program is compiled
against a new version of GLib but run against an old version.

trivially (for example, by passing a `sizeof()`), so that they use

caused problems, but it will soon be deprecated, so best port away from

Split out XDG_CURRENT_DESKTOP handling to a separate function and make
sure that it drops all the invalid entries properly. Earlier a bad
entry could slip through the checks by sitting just after another bad
entry, like in env being set to `invalid1!:invalid2!`, where
`invalid2!` could slip the checks.
It occasionally fails in CI with output like:

- 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.
