Despite linked lists being a fairly fundamental computer science
concept, some developers insist on using:
g_list_length (list) > 0
to determine whether a list is non-empty, rather than using:
list != NULL
Add a comment to the documentation for g_list_length() and
g_slist_length() pointing out the better alternative in the hope that it
will prevent some of this abuse.

gmem.h and gthread.h made use of the inline keyword, that is not available
on all compilers in C-mode, causing builds to break on such compilers.
Include glib/gutils.h which handles the inline issue, in place of
glib/gtypes.h if applicable, which is included quite early on by
glib/gutils.h.

We have a test that #includes our headers from a C++ program to make
sure we don't throw any errors or warnings as a result of that.
The new inline implementation of g_steal_pointer() does an implicit
conversion from (void *), which is not valid in C++.
Add a cast to avoid the problem.
Thanks to Ignacio Casal Quinteiro for the report.
This is particularly nice when used with g_autoptr(). See examples in
the docs.
This patch is based upon an idea (and original patch submission) from
Will Manley <will@williammanley.net>.

Document each of the baked-in CClosure marshallers that we have in
gobject, along with their #GVaClosureMarshal equivalents.
Based on a patch from Xavier Claessens <xavier.claessens@collabora.com>.
This is made by doing a build with --rebuild-types option,
then manually remove those functions:
g_win32_input_stream_get_type
g_win32_output_stream_get_type
g_io_extension_get_type
Maybe Makefile.am could remove them automatically so we can
remove gio.types from git and rely on --rebuild-types option?
Add g_list_store_insert_sorted() which takes a GCompareDataFunc to
decide where to insert. This ends up being a very trivial function,
thanks to GSequence.

Use the (private) _GLIB_DEFINE_AUTOPTR_CHAINUP macro for
G_DECLARE_DERIVABLE_TYPE and G_DECLARE_FINAL_TYPE so that we will
attempt to typedef and define items necessary for GCC
__attribute__((cleanup)) on, well, GCC only.
This fixes the build on non-GCC.
https://bugzilla.gnome.org/show_bug.cgi?id=743640
This is necessary as we are using _GLIB_AUTOPTR_TYPENAME and
_GLIB_AUTOPTR_FUNC_NAME in gtype.h for G_DECLARE_DERIVABLE_TYPE and
G_DECLARE_FINAL_TYPE, but _GLIB_AUTOPTR_TYPENAME and
_GLIB_AUTOPTR_FUNC_NAME expand to nothing on non-GCC, causing builds on
non-GCC to break, due to bad typedef and function definitions.
This patch defines a new private macro which does what is needed on GCC
builds and does nothing on non-GCC builds, thus fixing the build.
https://bugzilla.gnome.org/show_bug.cgi?id=743640
Add the missing 'none' argument to this macro in the non-GCC case. The
none parameter was added after the others and I forgot to update the
non-GCC case.

Rename the project to "install" the GLib files, as we are planning to have
a grand solution file that would build the entire GTK+ stack with its deps,
to ease the process for people building the GTK+ stack from a stock
installation of Visual Studio.
We are including the autocleanup headers as public headers for all builds,
although they work only for GCC in reality, so "install" them.
Also clean up a bit as we are having "\\" in places, where we only need
"\".
Automatically add support for the new cleanup macros to the type
declaration macros.
This is an API break because now your parent class needs to support
cleanup if you want to use G_DECLARE_*_TYPE. These macros are only 1
day old, however, so that's probably not a big problem (and we are
already busy adding the macros all over GLib and Gtk+).
https://bugzilla.gnome.org/show_bug.cgi?id=743640
Add g_auto() and g_autoptr() as helpers for declaring variables with
automatic cleanup.
Add some macros to help types define cleanup functions for themselves.
Going forward it will be an expectation that people use this macro when
creating a new type, even if they do not intend to use the auto-cleanup
functionality for themselves.
These new macros only work on GCC and clang, which is why we resisted
adding them for so long. There exist many people who are only
interested in writing programs for these compilers, however, and a
similar API in libgsystem has proven to be extremely popular, so let's
expose this functionality to an even wider audience.
We ignore deprecation warnings when emitting the free functions, which
seems suspicious. The reason that we do this is not because we want to
call deprecated functions, but just the opposite: sometimes the free
function will be an _unref() function that is only AVAILABLE_IN newer
versions, and these warnings are also implemented as deprecation
warnings.

Make sure that we only match the _get_type() function name by
restricting the regexp to matching [A-Za-z0-9_]. We were matching on .*
before which means that if we had two _get_type() functions appearing on
a single line then we would get everything in between them included (by
the default rule of '*' being greedy).
This affected G_DECLARE_*_TYPE which puts several uses of _get_type()
into a single line.
GListModel is an interface that represents a dynamic list of GObjects.
Also add GListStore, a simple implementation of GListModel that stores
all objects in memory, using a GSequence.
