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.

Commit 8ece2de964 transplanted a block of
code that contained an early-exit-on-error case which freed several
variables.
Because of the move, the normal-path unconditional free of one of these
variables is now above this early exit case, so if this block is hit, it
will now be a double-free.
Remove that.

It was removed, apparently accidentally, in commit 5b48dc4.
This had the side-effect that it wasn't included in tarball releases,
which means that commit ab7b4be doesn't work when building a package.

It's a platform-specific macro, so it belongs in glibconfig.h.
This ensures that g-ir-scanner will not pick the wrong definition
for introspection.
https://bugzilla.gnome.org/show_bug.cgi?id=757294
Currently the doc is incomplete when builddir!=srcdir
(e.g. debian package) because glibconfig.h is generared from
configure.ac and is thus missing from srcdir. This leads to
missing doc for symbols like G_GINT64_FORMAT.

Add some simple testcases for the new bounds-checked integer arithmetic
helpers.
Include a second build of the testcase to make sure we test the fallback
code even if we are on a compiler that supports the intrinsics.
https://bugzilla.gnome.org/show_bug.cgi?id=503096
Add some helpers for builds-checked unsigned integer arithmetic to GLib.
These will be based on compiler intrinsics where they are available,
falling back to standard manual checks otherwise.
The fallback case needs to be implemented as a function (which we do
inline) because we cannot rely on statement expressions. We also
implement the intrinsics case as an inline in order to avoid people
accidentally writing non-portable code which depends on static
evaluation of the builtin.
For now there is only support for addition and multiplication for guint,
guint64 and gsize. It may make sense to add support for subtraction or
for the signed equivalents of those types in the future if we find a use
for that.

Add a dummy definition for Clang's __has_builtin() macro. This will
allow us to use __has_builtin() unconditionally, in the same way as we
already do for __has_feature().

The Windows API function RtlGetVersion() is actually a function that is
decorated by WINAPI (i.e. __stdcall), so we need to correct this so that
the symbol can be loaded correctly from ntdll.dll, so that we won't crash as
a result. Should fix the crash due to stack overflow on 32-bit builds.

The new "slowly add more task threads" code doesn't fully deal with
apps that queue lots and lots of tasks which then block on tasks from
their task threads. Fix this by bringing back the "task is blocking
other task" check and making sure that such tasks get bumped to the
front of the queue.

ntdef.h is a header that is normally only shipped with MinGW, not Visual
Studio, which broke the build in commit 975cb91. Fix this by including
winternl.h, which typedef's the NTSTATUS type in question on both Visual
Studio and MinGW/mingw-w64, as well as pre-2008 Visual Studio.
Clean up this inclusion part a little bit as well.
If we fail to PeekMessage or PostMessage we should make sure
that the output parameter bytes_read/written is set 0 instead
of being left uninitialized. This fixes an assertion in the io
channel call where the following invariant is checked:
(status == G_IO_STATUS_NORMAL) || (read_size == 0)
Ignore trailing whitespace when reading boolean values. Currently it is
very easy to manually edit a keyfile to be:
[section]
key=true_
Where '_' is a space character. g_key_file_get_boolean will read this value as
false and this is hard for a user to detect (it will be reported in GError
as an invalid value).
Trailing whitespace is ignored for numbers for the same reason. This was
fixed in 7a45dde4fe.

Now that we initialize the quark tables from a constructor,
reloading libglib is just as bad as reloading libgobject,
so add the linker option to the LDFLAGS for all our libraries.

Change it to a running example of a file viewer application with a file
class and various derived classes and related interfaces. Hopefully the

We were using the time() library call to get the current time from the
system in order to compare it to the time returned by
g_date_time_new_now().
Of course, we took care to ensure that the time (in seconds) didn't
change in the middle of this process by checking the before and after
value of the system time.
Unfortunately, the system time as measured by time() was being taken
from a less-accurate clock source than the time used by GDateTime. As a
result, we could have GDateTime already into the next second while the
"seconds" value of the time returned by time() was still in the last
one, even when checked "after".
Avoid the problem by using the same ultimate source for time --
g_get_real_time().
This is based on a similar patch from Iain Lane, but it uses
g_get_real_time() instead of g_get_current_time().

This function provides an O(1) check to determine if a sequence is empty.
Compare this to the two following alternatives to perform the same check.
O(h): if (0 == g_sequence_get_length (seq))
O(2h): if (g_sequence_get_begin_iter(seq) == g_sequence_get_end_iter(seq))
Where `h' is the height of the tree.
