To avoid potential regression in feature check that configures
`HAVE_PROC_SELF_CMDLINE` treat test failures on Linux as fatal.
This restores behaviour from before 4c038a27ff.
GitLab can show the results of a CI pipeline if the pipeline generates a
report using the JUnit XML format.
Since Meson provides a machine parseable output for `meson test`, we can
take that and turn it into XML soup.
Instead of hardcoding /proc/self/cmdline use for __linux__ only,
do a configure-time test for it.
Specifically, this enables /proc/self/cmdline use on Cygwin.
The configure-time test is very primitive (just tests that the
file exists and that it's possible to read more than one byte from it),
relying on the testsuite for more extensive checks.
The test in the testsuite is modified to always run, even on platforms
where it isn't supposed to pass. If it fails there, the testing framework
skips it. If the test unexpectedly passes, that is reported too.
It can return NULL if no program name has been set yet (i.e.
g_set_prgname() has not been called from somewhere).

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
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.
