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"

This macro was lost during meson migration. Set it again.
Also explain that Cygwin maintainers applied patches[0] to glib that
simply marked all G_PLATFORM_WIN32-protected code as !defined(G_WITH_CYGWIN),
i.e. they did not want that code to compile.
Instead of altering ifdef guards all over the place, we'll just
not define G_PLATFORM_WIN32 for Cygwin anymore.

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.

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.
