If `right` and `left` are both near `G_MAXUINT`, it’s possible for the
addition to overflow, even if the eventual result would fit in a
`guint`. Avoid that by operating on the difference instead.
The difference is guaranteed to be positive due to the prior `left <=
right` check.

The allocation size was set correctly before, but not the array length,
so the copied array appeared to have zero elements.

We want to use the keyfile backend in sandboxes,
but we want to avoid people losing their existing
settings that are stored in dconf. Flatpak does
a migration from dconf to keyfile, but only if
the app explictly requests it.
From an app perspective, there are two steps to
the dconf->keyfile migration:
1. Request that flatpak do the migration, by adding
the migrate-path key to the metadata
2. Stop adding the 'dconf hole' to the sandbox
To keep us from switching to the keyfile backend
prematurely, look at whether the app has stopped
requesting a 'dconf hole' in the sandbox.
The plugin modules in these tests get statically linked with a separate
copy of GLib so they end up calling vfuncs in their own copy of GLib.

Connect the dots between G_ADD_PRIVATE and the various G_DEFINE_* macros
that use it, as well as expanding the code example for
G_DEFINE_TYPE_EXTENDED with a private instance data declaration.
Closes: #943
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.
