GTimeVal is subject to the year 2038 problem, since its `tv_sec` field
is a `glong`, which is 32 bits on 32-bit platforms.
Use `guint64` to represent microsecond-precision time since the Unix
epoch; or use `GDateTime` for full date/time representation.

Fixes: #1438
It’s not Y2038-safe, as it’s 32-bit. While it was previously deprecated
in the documentation, now add the deprecation annotation for the
compiler.

The documentation has marked it as deprecated for a long time, but not
in a structured way. Use the gtk-doc ‘Deprecated’ tag to mark it as
deprecated.

There are languages where a name of one month is a substring of another.
Instead of stopping search on the first match use the month that
constitutes the longest match.
Fixes#1343.
When g_date_set_parse was used with more than one locale it could
incorrectly retain information from previous one. Reinitialize all
locale specific data inside g_date_prepare_to_parse to avoid the issue.
It might not be immediately obvious that this is the case. Let's record
it in the description of `GTimeVal` itself and also in
`g_time_val_from_iso8601`.
We also drop an incorrect statement in the documentation for
`g_time_val_from_iso8601` stating that years up to 3000 were supported;
this is also not true for the same reason.

Use either g_get_real_time() or g_date_time_new_now_local(). This means
we don’t need to worry about time_t being 32b in future (the year 2038
problem), and it makes the need for error handling a bit more explicit.
Improve the error handling in several cases.

g_date_strftime() on Windows uses the SYSTEMTIME structure which requires the
year to be >=1601. Passing 1 results in a negative SYSTEMTIME.wYear
which makes GetDateFormatW() fail and crashes due to missing error handling.
Just use 1976 as that's already used a few lines down.
All those logging functions already add a newline to any message they
print, so there’s no need to add a trailing newline in the message
passed to them.

Make it more obvious that an explicit check isn’t needed for the upper
bound on years, since it’s limited by the type width.
Add a unit test to demonstrate this.

GDate.dmy is a 1-bit bitfield which is treated as a boolean. However,
it’s still an integer, and we can’t really treat it like a gboolean
because it’s a bitfield. Make the comparisons with it explicitly compare
integers, rather than implicitly, to make it more obvious that it is
actually an integer.
This introduces no functional changes.

Some source code comments amended to avoid possible future confusion.
It has been explained that a month name is used in a genitive case
only if it is required by the language rules. Also it has been
explained that %OB is also supported by other platforms (e.g., BSD)
but for this test we are focused on glibc 2.27 vs. Windows.

A similar change to the commit be4f96b6502c01d2a51d60b7a669c8ef82e22a4d,
supports %OB, %Ob, %Oh (alternative, standalone, nominative) month names
along with the old %B, %b, %h (primary, in full date format context,
genitive) month names.

Commit 0817af40e8c74c721c30f6ef482b1f53d12044c7 breaks the build on
older versions of GCC, which don't allow pragma inside functions.

Add various (nullable) and (optional) annotations which were missing
from a variety of functions. Also port a couple of existing (allow-none)
annotations in the same files to use (nullable) and (optional) as
appropriate instead.
Secondly, add various (not nullable) annotations as needed by the new
default in gobject-introspection of marking gpointers as (nullable). See
https://bugzilla.gnome.org/show_bug.cgi?id=729660.
This includes adding some stub documentation comments for the
assertion macro error functions, which weren’t previously documented.
The new comments are purely to allow for annotations, and hence are
marked as (skip) to prevent the symbols appearing in the GIR file.

Back in the far-off twentieth century, it was normal on unix
workstations for U+0060 GRAVE ACCENT to be drawn as "‛" and for U+0027
APOSTROPHE to be drawn as "’". This led to the convention of using
them as poor-man's ‛smart quotes’ in ASCII-only text.
However, "'" is now universally drawn as a vertical line, and "`" at a
45-degree angle, making them an `odd couple' when used together.
Unfortunately, there are lots of very old strings in glib, and also
lots of new strings in which people have kept up the old tradition,
perhaps entirely unaware that it used to not look stupid.
Fix this by just using 'dumb quotes' everywhere.
