Add g_steal_pointer() and g_clear_object() calls in various places to
clarify the ownership transfers for GDBusMessage instances, in a bid to
understand what’s going on in this code and to try to find a
use-after-finalize problem.
This introduces no functional changes, but hopefully makes the code a
little clearer.

If the filter function for an outgoing message fails to copy the
GDBusMessage, that failure was previously ignored, and GDBusMessage
methods could be called on a NULL instance.
Avoid that.

Rather than keeping a reference to the GThreadedSocketService as the
user_data for every thread pool job, add it to a member of the per-job
data struct (GThreadedSocketServiceData). This should make no
difference overall, as it’s just moving the refcounting around, but it
does seem to fix an occasional double-unref crash on shutdown where the
GThreadedSocketService is unreffed during finalisation.
In any case, it makes the object ownership clearer.

Check for RTLD_NEXT being present, and disable the gsocketclient-slow
test if it's absent, since the shlib dependency of that test requires
RTLD_NEXT to function.
This allows the testsuite to be built on Cygwin, which behaves
exactly like UNIX, but doesn't have RTLD_NEXT.
On OSX both backends are built. Generally we want to use the cocoa
backend by default and in case it is not supported, i.e because
the application is not using a bundle then we should fallback
to the gtk one.
ostream_flush_cb() was calling flush_data_list_complete() with a single
element list with an item that had already been freed. This was observed
on OpenBSD where memory is overwritten with 0xdf during free():
error=0x0) at ../glib-2.58.3/gio/gdbusprivate.c:1156
1156 g_mutex_lock (&f->mutex);
(gdb) p /x *f
$74 = {mutex = {p = 0xdfdfdfdfdfdfdfdf, i = {0xdfdfdfdf, 0xdfdfdfdf}},
cond = { p = 0xdfdfdfdfdfdfdfdf, i = {0xdfdfdfdf, 0xdfdfdfdf}},
number_to_wait_for = 0xdfdfdfdfdfdfdfdf, error = 0x0}
This happened because the thread freeing the element didn't properly wait
for the asynchronous flush operation to finish.
Gnome's developer docs say: "g_cond_wait() must always be used in a loop"
https://developer.gnome.org/glib/stable/glib-Threads.html#g-cond-wait
It returns a string in the libc locale, which is not necessarily UTF-8.
Convert that to UTF-8 before returning it to the caller.

Fixes: #1732
More mounts can have same mount path, but only the last one is
accessible. Thus we should always return the last matching mount from
g_unix_mount_at() and g_unix_mount_for(). This should also solve
problems with g_file_trash() on automounted filesystems, which are
caused by the recently added mount checks.
Closes: https://gitlab.gnome.org/GNOME/glib/issues/1727
instead of using a generic G_IO_ERROR_FAILED error code.
This is in line with what W32 part of the code is doing with WSAENOTSOCK.
This fix will break two tests in libsoup, which were written following
the implementation and thus expect G_IO_ERROR_FAILED when attempting to
do stuff with no-longer-valid socket descriptors.
This reverts commit 80fcb1bc26.
G_DISABLE_DEPRECATED should never be used by anybody, least of all by
GLib. We have deprecation annotations for the compiler, these days, and
they are much better suited than a macro that makes symbols appear and
disappear. The fact that gtk-doc doesn't understand the deprecation
annotations is a limitation of gtk-doc, and it's gtk-doc that ought to be
fixed.
Commit 80fcb1bc broke GStreamer, which disables old API that was
deprecated before the introduction of the deprecation annotations, but
still uses newly deprecated one, and relies on the deprecation
annotations to do their thing. It also broke libsoup, as it uses
GValueArray in its own API.
Just skip the test if the unix transport isn’t supported. This means we
get better compilation coverage, and more explicit TAP output saying
that the test is being skipped on unsupported platforms.

The specification doesn’t explicitly say this, but it doesn’t say
otherwise, and it would be pretty weird to have an empty transport name
or key.

No need for the `meaningless` label and some unreachable if-branches.

While gtk-doc can currently detect a link to a symbol which has been
pluralised by adding ‘s’, it can’t detect when ‘es’ is added. While
that’s being fixed, reword the documentation so the links are generated
correctly anyway.

As pointed out by gtk-doc, these are all symbols which have been marked
as deprecated, but which aren’t protected by a deprecation guard. We
can’t use G_DEPRECATED_IN_* for them, as they are all non-function
symbols. Instead, wrap them in #ifndef G_DISABLE_DEPRECATED.
In some cases, we also need to wrap one or two functions which use the
deprecated types in G_DISABLE_DEPRECATED too.
