These make it easy to steal elements from pointer arrays without having
the array’s GDestroyNotify called on them, similarly to what’s possible
with g_hash_table_steal().

If using g_ptr_array_remove*() with a non-NULL GDestroyNotify function,
the value returned will probably be freed memory (depending on what the
GDestroyNotify) function actually does. Warn about that in the
documentation. We can’t just unconditionally return NULL in these cases,
though, since the user might have set the GDestroyNotify to a nifty
function which doesn’t actually free the element; so returning it might
still be valid and useful.
Also add missing (nullable) annotations to that documentation.

On Windows we use gnulib and elsewhere we use glibc or similar.
Also change G_GNUC_PRINTF to use gnu_printf instead of __format__ if
possible because __format__ evaluates to ms_printf under MinGW,
but we use gnulib there and not the system printf.
gnu_printf is only available with GCC>=4.4 and not with clang.

The timezone setup utility of FreeBSD, tzsetup, which is run during the
installation, creates /etc/localtime by copying the chosen timezone file
from /usr/share/zoneinfo. Although it can correctly deal with the case
where /etc/localtime is a symlink, it is not the default and there is no
user interface to change the default copying behaviour.
Fortunately, tzsetup has been modified to write the name of the chosen
timezone to /var/db/zoneinfo in 2009, so we can know the name of the
current timezone by reading it. DragonflyBSD also seems to do the same
thing in its tzsetup.

It seems that the test expects g_date_time_format to return formatted
results in English, and there is no setlocale (LC_ALL, "") call in the
file so the test does run in the default C locale. However, gettext
seems to read the value of LC_MESSAGES from the environment by itself.
Even if the value of LC_MESSAGES locale is C because of not calling
setlocale, gettext still translates the name of the month according to
the LC_MESSAGES environment variable, causing g_date_time_format_locale
to fail on the "%b" test case because it cannot convert UTF-8 text
returned by get_month_name_with_day to ASCII.
To avoid the test failure, we set the LC_MESSAGES environment variable
to C before format tests and restore it at the end of the function.

The return value of g_file_read_link ("/etc/localtime") can
be a relative path in the form of "../usr/share/zoneinfo".
This breaks the prefix check that is performed, and makes
the timezone identifier be "../usr/share/zoneinfo/America/Sao_Paulo",
for example, which breaks other parts of the system.
Fix that by canonicalizing the symlink path if we detect
is it a relative path.
(Tweaked by Philip Withnall <withnall@endlessm.com> to remove a
conditional which was unnecessary.)

Getting the canonical filename is a relatively common
operation when dealing with symbolic links.
This commit exposes GLocalFile's implementation of a
filename canonicalizer function, with a few additions
to make it more useful for consumers of it.
Instead of always assuming g_get_current_dir(), the
exposed function allows passing it as an additional
parameter.
This will be used to fix the GTimeZone code to retrieve
the local timezone from a zoneinfo symlink.
(Tweaked by Philip Withnall <withnall@endlessm.com> to drop g_autofree
usage and add some additional tests.)

If g_get_home_dir() calculated a NULL home directory (due to $HOME being
unset and /etc/passwd being inaccessible, for example due to an
overly-zealous LSM), it would call g_once_init_leave (&home_dir, NULL),
which would emit a critical and fail to leave the GOnce critical
section. That meant that the following call to g_get_home_dir() would
deadlock in g_once_init_enter().
Fix that by setting the home directory to a made-up value in such cases
(which the documentation handily already explicitly allows).

This is a non-trivial accessor which gets the identifier string used to
create the GTimeZone — unless the string passed to g_time_zone_new() was
invalid, in which case the identifier will be `UTC`.
Implementing this required reworking how timezone information was loaded
so that the tz->name is always set at the same time as tz->t_info, so
they are in sync. Previously, the tz->name was unconditionally set to
whatever was passed to g_time_zone_new(), and then not updated if the
tz->t_info was eventually set to the default UTC information.
This includes tests for the new g_time_zone_get_identifier() API, and
for the g_date_time_get_timezone() API added in the previous commit.

We do not need to use FindFirstFileW() to get a reparse tag if the

If a handle was obtained from a fd that we got from up the stack,
we shouldn't call CloseHandle() on it in case of an error.
This is a bug. Luckily, it happens only on the error codepath, so,
hopefully, no one had hit it yet.
Accurate G_HAVE_GNUC_VISIBILITY is needed to correctly
define G_GNUC_INTERNAL later on. Autotools did that,
meson currently doesn't and opts to just set
G_HAVE_GNUC_VISIBILITY to 1 for all compilers except MSVC.
This leads to MinGW GCC having G_HAVE_GNUC_VISIBILITY=1,
which results in G_GNUC_INTERNAL being defined to
__attribute__((visibility("hidden"))), which is not supported.
Because cc.compiles() does not support override_options or
anything like that, we just feed it '-Werror' as-is, since
MSVC is known as not supporting visibility attributes anyway.
