If we're writing the body to standard output, we cannot know what the
filename of the corresponding header is going to be, but it seems
vanishingly unlikely that it will be either `stdout.h` (which we would
traditionally have generated) or `-.h` (which we would have generated
since !3886).
This makes some of the output snippets sufficiently short that black(1)
requires that they are folded into a single line.

In command-line tools, ordinary filenames normally do not have
special-cased meanings, so commit 3ef742eb "Don't skip dbus-codegen tests
on Win32" was a command-line API break: in the unlikely event that a
user wanted to write to a file named exactly `stdout`, this would have
been an incompatible change.
There is a conventional pseudo-filename to represent standard output,
which is `-` (for example `cat -` is a no-op filter). Adding support
for this is technically also a command-line API break (in the very
unlikely event that a user wants to write to a file named exactly `-`,
they would now have to write it as `./-`), but filenames starting with
a dash often require special treatment anyway, so this probably will not
come as a surprise to anyone.
When the output filename is `-` we don't want to use `#ifdef _____` as
a header guard, so special-case it as `__STDOUT__` as before.

This reverts commit fbdc9a2d03.
It was not submitted through a merge request and broke CI. Reverting it
immediately to unbreak CI and hence the rest of the development
pipeline. The changes can be re-submitted as a merge request so they’re
properly tested in CI before being merged.

This fixes a race condition which frequently caused the
`memory-monitor-dbus.py` test to fail.
The registration of the `LowMemoryMonitor` object on the bus, and the
`GMemoryMonitorDBus`’s connection to the warning signal raced, such that
it was possible for the mock `LowMemoryMonitor` to emit a warning signal
before the `GMemoryMonitorDBus` proxy was listening, and hence the proxy
would never see the signal.
Fix this by explicitly synchronising the two before proceeding to the
tests.
Make the same changes in the `memory-monitor-portal.py` test too, even
though that one was not failing. This should remove the need for a 2s
wait on every test run.

Rather than sleeping and blocking everything, use a timeout source on
the main context so that inputs can continue to be handled while waiting
for a timeout.
This introduces no functional changes to the test.

It should be doing already (or the tests would never work), but make it

I ran Bustle/dbus-monitor on the session bus while running the full GLib
test suite, and noticed that these tests were causing `Launched` signal
emissions on the main session bus. That suggested they weren’t isolated
properly, which at best causes noise on the bus and at worst could cause
spurious test failures.
Fix that by running those tests in a `GTestDBus` environment, as some of
the other appinfo tests already are.

There are several reasons why we might not be able to do the test setup
for --external-data: non-Linux platform, missing ld or objcopy,
objcopy doesn't support --add-symbol, or the CPU family is MIPS
(on which cc -r does not necessarily emit the specific MIPS ABI flavour
that we are targeting, for example different functionality levels or
different NaN encodings).
If we can't link in the test data, then obviously this test is not going
to pass. It was already skipped on non-Linux, but not on platforms that
hit one of the other reasons for the test setup to fail.
In particular, this test failed on Debian mips64el since commit 81059169,
which stopped linking the necessary resource on MIPS platforms, but
continued to assert that the resource is present at runtime.

This is just the result of running `black $(git ls-files '*.py')`.
For some reason, the `sh-and-py-check` CI job didn’t run on merge
request !3751, so this non-standard formatting slipped through onto
`main`.

It can cause failures for shared connection objects.
What can currently happen is this:
1. A user starts to asynchronously create a proxy object
2. A user starts to asynchronously create another proxy object
At this point, the asynchronous initialization for the two proxy objects
share the not yet initialized connection object.
3. While the shared connection objected is created, the user cancels the
creation with the supplied cancellable from the fist proxy object.
4. initable_init caches the canceled error and marks the connection as
initialized.
5. The initialization of the second proxy object fails with the same
canceled error.
To avoid this, clear the error in this case and destroy any member
variables that may have been created before the creation was canceled.
This way, the initialization of the second proxy object will restart the
connection initialization and with probably succeed.

Previously, the code only validated the types of *required* message
headers, and did not validate optional ones.
Now, the headers are validated in one step, and a subsequent step checks
whether the required ones are present.
The existing tests have been updated to match the new error message
wording. More tests will be added to test the new behaviour in a
subsequent commit.

Before checking the properties of `*_proxy`, assert that there were no
errors in constructing the proxy first. Otherwise the property checks
will crash on `NULL` pointer dereferences.
The test is still intermittently buggy somewhere, but at least this

GDBus has always supported matching strings with arg0 matching
(`G_DBUS_SIGNAL_FLAGS_MATCH_ARG0_PATH`). In D-Bus 1.5, support was added
to the spec for also matching object paths. This got forgotten about and
was never added to GDBus, meaning that
`G_DBUS_SIGNAL_FLAGS_MATCH_ARG0_PATH` won’t match against a signal arg0
of type `o`.
Fix that, and add a unit test.
To do so, we need to add a new `g_dbus_message_get_arg0_path()` API to
complement the existing `g_dbus_message_get_arg0()` API. The approach of
letting `g_dbus_message_get_arg0()` return an object-path *or* a string
would not work, as it’s also called in the implementation of
`G_DBUS_SIGNAL_FLAGS_MATCH_ARG0_NAMESPACE`, which must only match
string-typed arg0 values and not object-path-typed ones.

The `g_content_type_guess_for_tree` function segfaults currently when
processing filenames that are not valid unicode strings. Let's use the
`g_filename_to_utf8` and `g_utf8_make_valid` functions before other
processing to prevent that.
Let's also add a test for it to avoid this in future.
