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.

Change it to a running example of a file viewer application with a file
class and various derived classes and related interfaces. Hopefully the
reader can relate to this a little better than to their maman.

Add string serialisation functions for GNetworkAddress, GSocketAddress,
GUnixSocketAddress, GInetSocketAddress, GNetworkService and
GSocketConnectable. These are intended for use in debug output, not for
serialisation in network or disc protocols.
They are implemented as a new virtual method on GSocketConnectable:
g_socket_connectable_to_string().
GInetSocketAddress and GUnixSocketAddress now implement
GSocketConnectable directly to implement to_string(). Previously they
implemented it via their abstract parent class, GSocketAddress.

GDatagramBased is an interface abstracting datagram-based communications
in the style of the Berkeley sockets API. It may be contrasted to (for
example) GIOStream, which supports only streaming I/O.
GDatagramBased allows socket-like communications to be done through any
object, not just a concrete GSocket (which wraps socket()).
This adds the GDatagramBased interface, and implements it in GSocket.

Remove some outdated references to an old example, and add a row in the
table of steps in object initialization for the GObjectClass.constructed
virtual method.

Add support for receiving multiple messages with a single system call,
using recvmmsg() if available. Otherwise, fall back to looping over
g_socket_receive_message().
This adds new API, g_socket_receive_messages(), and corresponding unit
tests.
https://bugzilla.gnome.org/show_bug.cgi?id=751924
This complements the GOutputMessage struct. It will shortly be used for
adding a g_socket_receive_messages() function, but needs to be committed
first to allow some internal refactoring of GSocket.

GListStore already has a g_list_store_insert_sorted function,
which can be used to keep the list sorted according to a fixed
sort function. But if the sort function changes (as e.g. with
sort columns in a list UI), the entire list needs to be
resorted. In that case, you want g_list_store_sort().

• Remove copies of function declarations from the explanation — if
people want those, they can follow links to the reference manual.
• Add markup to make C code more defined.
• Remove use of first person and irrelevant name dropping.

So that first-time users don’t fall into the trap of reading about the
gory memory layout details of GType and GObject when all they wanted to
do was derive a class.

Use G_DECLARE_INTERFACE and G_DEFINE_INTERFACE. Fix a couple of typos.
Add some comments to empty functions to make it obvious they’re
intentionally empty.

Restructure the section of the how-to which covers the header and source
code boilerplate for declaring and defining GObjects to use the new
G_DECLARE_*_TYPE macros. Present both final and derivable types.
Trim various supporting paragraphs.
Rename ‘class functions’ to ‘virtual functions’ to use consistent,
modern terminology.

This is meant for opaque, non-POSIX-like backends to indicate that the
URI is not persistent. Applications should look at
G_FILE_ATTRIBUTE_STANDARD_SYMLINK_TARGET for the persistent URI.
Examples of such backends could be a portal for letting sandboxed
applications access the file-system, or a database-backed storage like
Google Drive.
In these cases, the user visible file and folder names are different
from the real identifiers, used by the backend. So, a request to
create google-drive://user@gmail.com/foo/New\ File, would actually
lead to google-drive://user@gmail.com/foo/bar on the server even though
the user visible name is still "New File". Since the server-defined URI
is persistent and sanity-checked by the backend, it is recommended that
applications switch to it as soon as possible. Backends will try to
keep a mapping from "fake" to "real" URIs, but those are only on a
best effort basis. They might not be persistent or have the same
guarantees as the "real" URIs.

Make it a little easier to find the GType conventions page, which I
guess should be the canonical guide to how to name things.
This adds a brief mention of the valid characters in a type name to the
conventions page.

This is a binding-friendly version of g_dbus_connection_register_object.

Add a property to GNetworkMonitor indicating if the network
is metered, e.g. subject to limitations set by service providers.
The default value is FALSE

Instead of just dropping address types that we're not specifically
handling we return a GNativeSocketAddress which is just a dummy
container for the stuct sockaddr.

This allows the caller to know when a socket has been bound so that
it can for instance set the SO_SENDBUF and SO_RECVBUF socket options
before listen is called

Fix a few typical problems, and also stop wrapping the inline definition
of g_steal_pointer in parens, since it is not necessary and it confuses
gtk-doc.
This can be used to query whether the task has completed, in the sense
that it has had a result set on it, and has already – or will soon –
invoke its callback function.
Notifications for this property are emitted immediately after the task’s
main callback, in the same main context as that callback. This allows
for multiple bits of code to listen for completion of the GTask, which
opens the door for blocking on cancellation of the GTask and improved
handling of ‘pending’ behaviour.

This is a singleton, but we have a function called _new() to get it.
What's worse is that the documentation makes no mention of this, and
actually specifically says that a new monitor will be created each time.

This is *significantly* more pleasant to use from C (while handling
errors and memory cleanup).
While we're here, change some ugly, leaky code in
tests/desktop-app-info.c to use it, in addition to a test case
in tests/file.c.

g_application_bind_busy_property() had the restriction that only one
property can be bound per object, so that NULL could be used to unbind.
Even though this is enough for most uses, it is a weird API.
Lift that restriction and add an explicit unbind function.
https://bugzilla.gnome.org/show_bug.cgi?id=744565
Balancing g_application_{un,}mark_busy() is non-trivial in some cases.
Make it a bit more convenient by allowing to bind multiple boolean
properties (from different objects) to the busy state. As long as these
properties are true, the application is marked as busy.

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.

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.

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.
https://bugzilla.gnome.org/show_bug.cgi?id=729351
Add G_DECLARE_DERIVABLE_TYPE() and G_DECLARE_FINAL_TYPE() to allow
skipping almost all of the typical GObject boilerplate code.
These macros make some assumptions about GObject best practice that mean
that they may not be usable with older classes that have to preserve
API/ABI compatibility with a time before these practices existed.

Currently the only way to set a state hint on an action is through a
subclass; add a g_simple_action_set_state_hint() method so that this
becomes easier for clients that already use GSimpleAction.

Along the same lines as g_clear_object(), g_set_object() is a
convenience function to update a GObject pointer, handling reference
counting transparently and correctly.
Specifically, it handles the case where a pointer is set to its current
value. If handled naïvely, that could result in the object instance
being finalised. In the following code, that happens when
(my_obj == new_value) and the object has a single reference:
g_clear_object (&my_obj);
my_obj = g_object_ref (new_value);
It also simplifies boilerplate code such as set_property()
implementations, which are otherwise long and boring.
Test cases included.

This is a convenience method for creating a GNetworkAddress which is
guaranteed to return IPv4 and IPv6 loopback addresses. The program
cannot guarantee that 'localhost' will resolve to both types of
address, so programs which wish to connect to a local service over
either IPv4 or IPv6 must currently manually create an IPv4 and another
IPv6 socket, and detect which of the two are working. This new API
allows the existing GSocketConnectable machinery to be used to
automate that.
Based on a patch from Philip Withnall.
