We need to enable building the dirent and gnulib sources for clang-cl,
as we are still using the Microsoft-style headers and lib's and CRT.
We need to also do this for the following, for similar reasoning:
-Symbol export (via __declspec(dllexport))
-Dependency discovery without pkg-config files
-long long and ssize_t detection
We do, however, enable the autoptr tests for clang-cl builds. Note that
at this point real MSVC builds are still better supported than clang-cl
builds, and it will likely remain so for at least the near future,
alhtough real MSVC builds of the GTK stack are consumable and are usable
by clang-cl.
Use the GCC-style definition for the deprecation warning macros so that
builds using those won't break due to how they are placed as clang-cl
seems to not support __declspec(deprecated) very well. Also make sure
that we do indeed support the temparary disabling of deprecation
warnings on clang-cl, as the MSVC ones don't really work on clang-cl.
clang-cl does support __attribute__((cleanup)), which is what is used
for the g_auto* macros, but neither it, nor clang.exe defines __GNUC__
when they are used in a MSVC cmd.exe environment. It does, however,
define __clang__.
So, check for the presence of the __clang__ macro to enable g_autoptr as
well, so that we can build things with MSVC builds that make use
of g_autoptr via pretending to be MSVC by using clang-cl.
Commit 8cc92bcca ("meson: Turn selinux into a meson feature and make it
auto by default") update the selinux option to be a feature with
instead of a boolean. Update the documentation to reflect this.

Windows does not recognize the "America/Recife" as a valid timezone
identifier, so setting the TZ envvar to that will result in "UTC" to
be returned on Windows.
Instead, set TZ to be the Windows equivilant "SA Eastern Standard
Time", and see whether that is indeed our identifier when we create the
GTimeZone using that.
On Windows, we may be using the US DST boundaries by using the default
"Pacific Standard Time" for rules_from_windows_time_zone() in
rules_from_identifier(). This has the unfortunate side-effect of
hardcoding the out_identifier to "Pacific Standard Time", which is
likely not what we want.
Instead, upon retrieving the items successfully using
rules_from_windows_time_zone ("Pacific Standard Time", ...), we just
set the out_identifier to whatever identifier that was passed into
rules_from_identifier().
Update the gdatetime test program to make use of the updates that was
done in gtimezone.c in the previous commit, so that we don't have to
worry what language version of Windows the tests are being run in, but
instead be assured that we produce and check for the English-language
time zone name strings.
Also, instead of testing for "Pacific Standard Time" in
test_GDAteTime_printf(), use GetDynamicTimeZoneInformation() to get the
actual time zone string (where the system running the test program is)
we want to check for, because on Windows the actual result will be
dependent on which timezone the system running the test program is in.

The existing method of using RegQueryValueExW() to query the Std/Dlt
strings can only retrive the localized versions of those strings, so
that means they will vary by the language version of Windows. Instead,
use RegQueryValueExW() only as a fallback when RegLoadMUIStringW() fails,
as RegLoadMUIStringW() can query for the Std and Dlt strings in
whatever language we need by setting the locale stuff programatically on
the fly.
We are going to use RegLoadMUIStringW() in the next commit, since there
is no real RegLoadMUIStringA() function (it exists as a stub only).
This is done so that we are consistent along the way
Also fix rule_from_windows_time_zone_info() as we can't just do a strncpy()
of tzi->StandardName and tzi->DaylightName directly, as they are wchar_t/
gunichar2 strings, where we must convert to UTF-8 first.

We said the type must support being cleaned up and will be cleaned up in
an appropriate way, but in order to figure out how to do that, you had
to jump forward in the documentation to the other macros. Just say them.
This is a follow-up to a0c7f85437.
In addition LC_MESSAGES, we should remove LC_ALL from the environment
as well. Otherwise, LC_ALL overrides LC_MESSAGES, causing the test to
fail on FreeBSD when LC_ALL is set to a non-English locale.
In _g_object_unref_and_wait_weak_notify() we take a weak reference and
then call g_object_unref() in an idle callback, which may look like
we're dropping a strong reference without having one. So change the
comment to make it more clear that the reference being dropped is held
by the caller.
Now that we're not calling g_object_run_dispose() indirectly in
g_test_dbus_down() (see commit "Revert "gtestdbus: Properly close server
connections""), the test gdbus-connection-loss is failing with the
message "Bail out! GLib-GIO-FATAL-WARNING: Weak notify timeout, object
ref_count=1". This is because we're holding a reference to the singleton
connection object while calling session_bus_down() in the test's main().
So then we end up waiting for 30 seconds in
_g_object_unref_and_wait_weak_notify() for the GWeakNotify to be
triggered, which never happens.
The fix is to unref the connection before calling session_bus_down().
This is consistent with how other tests work, and is safe because the
only method called on the connection has already errored out, as
asserted by the test.
This reverts commit c37cd19fee.
Now that we've reverted the commit "gtestdbus: Properly close server
connections", g_test_dbus_down() no longer returns early and we no
longer need this workaround. Since the gdbus-names test seems to
properly unref its GDBusConnection objects it's not clear to me why it
needed the sleep to succeed. However even at the time the failure wasn't
reproducible according to this comment[1] so it's probably not worth
spending more effort trying to reproduce it now.

This reverts commit baf92d09d6.
Closes#787
According to the original commit, this change was made because otherwise
g_test_dbus_down() following a g_test_dbus_stop() hangs until it times
out. The timeout being referred to is the 30 seconds which are waited by
_g_object_unref_and_wait_weak_notify() for the GWeakNotify to be
triggered when the last strong reference to the singleton
GDBusConnection object is dropped. But the patch was not correct and the
leak should have instead been fixed by having the last strong reference
holder drop their reference on the GDBusConnection before calling
g_test_dbus_down(). Timing out after 30 seconds is the desired behavior
in the case where someone holds a reference to the singleton for that
entire period.
There are a few problems with this patch. First, as pointed out here[1],
calling g_object_run_dispose() in the idle callback means we are causing
the GWeakNotify to trigger ~immediately rather than waiting 30 seconds
to give another owner a chance to unref. Second, since someone else may
still hold a reference on the object being disposed, they may call
methods on it after it's been disposed which can seg fault as documented
here[2] and as I also saw recently in another project.
It's unclear what the original leak being fixed was, but many have been
fixed between 2013 and now. I ran all the unit tests under valgrind, and
some do fail (some consistently and some intermittently) but none of the
failures seem to only happen after this reversion commit. I also
couldn't find anywhere in the valgrind output where any GDBusConnection
objects are definitely being lost.
