Several different codebases in GNOME want to implement wall clocks.
While we could pretty easily share a private library, it's not a
substantial amount of code, and GLib already has a lot of the
necessary system-specific detection and handling infrastructure.
Note this initial implementation just wakes up once a second in the
cancel_on_set case; we'll add the Linux-specific handling in a
subsequent commit.

Rework property getters to use a vfunc so we can take the fast path
and avoid allocating memory for both the skeleton and the proxy
cases. This requires some special case because of how GVariant expects
you to free memory in some cases, see #657100. Add test cases for
this.
Document the _get_ functions as not being thread-safe and also
generate _dup_ C getters (which are thread-safe).
Mark all the generated _get_, _dup_ and _set_ as (skip) as non-C
languages should just use GObject properties and not the (socalled)
"C binding".

The main rationale for adding it was to avoid having gnome-shell
mmap'ing /etc/localtime once a second. However, we can just as easily
run inotify there, and given no one else was clamoring for a way to
detect when the time zone changes, I don't see a need for public API
here - at least not yet.
In the bigger picture, I just don't believe that the vast majority of
applications are going to go out of their way to instantiate and keep
around a random GTimeZoneMonitor class. And if they do, it's has the
side effect that for other bits of code in the process, local GDateTime
instances may start varying again!
So, if code can't rely on local GDateTime instances being in a
consistent state anyways, let's just do that always. The
documentation now says that this is the case. Applications have
always been able to work in a consistent local time zone by
instantiating a zone and then using it for GDateTime constructors.
We fix the "gnome-shell stats /etc/localtime once a second" issue by
using timerfd (in glib) and inotify (in gnome-shell).

This commit changes GLib size units policy. We now prefer SI units and
allow for use of proper IEC units where desired.
g_format_size_for_display() which incorrectly mixed IEC units with SI
suffixes is left unmodified, but has been deprecated.
g_format_size() has been introduced which uses SI units and suffixes.
g_format_size_full() has also been added which takes a flags argument to
allow for use of IEC units (with correct suffixes). It also allows for
a "long format" output which includes the total number of bytes. For
example: "238.5 MB (238,472,938 bytes)".

This commit represents an API break to GAction in the following ways:
- the 'set_state' entry in the GActionInterface vtable has been
renamed to 'change_state'. The number and order of vtable items has
not otherwise changed.
- g_action_set_state() has been renamed to g_action_change_state() to
match the updated vtable entry.
- the "state" property of the GAction interface has been changed to
read-only to reflect the fact that g_action_set_state() no longer
exists.
- GSimpleActionClass has been hidden. GSimpleAction can no longer be
subclassed.
>> Rationale
g_action_set_state() has never been a true setter in the sense that
calling it will update the value of the "state" property. It has always
been closer to "request 'state' to be changed to this value" with
semantics defined by the implementor of the interface. This is why the
equivalent method in GActionGroup had its name changed from 'set' to
'change'. This change makes the two interfaces more consistent and
removes any implication about the effect that calling set_state() should
have on the 'state' property.
>> Impact
This incompatible API break was undertaken only because I strongly
suspect that it will go entirely unnoticed. If the break actually
affects anybody, then we will accommodate them (possibly going as far as
to revert this commit entirely).
The virtual table change only impacts implementors of GAction. I
strongly suspect that this is nobody (except for GSimpleAction).
The hiding of GSimpleActionClass only impacts impacts subclasses of
GSimpleAction. I strongly suspect that none of these exist.
The changing of the property to be read-only only affects people who
were trying to change the state by using GObject properties. I strongly
suspect that this is nobody at all.
The removal of the g_action_set_state() call is the most dangerous, but
I still suspect that it will impact nobody outside of GLib. If anybody
is impacted by this change then, at their request, I will reintroduce
the API as a deprecated alias for g_action_change_state().
Rather than having the gtk-doc build machinery have a list of header
files to exclude, change the GLib build to dump a list of public

For example, if setting a property on a skeleton from another thread
than where it was constructed, the idle handler responsible for
emitting the PropertiesChanged() signal could run immediately and
clear skeleton->priv->changed_properties_idle_source causing
g_source_unref() to be called with a NULL pointer. This race was

In addition to fixing this race, also move the code for setting up the

to perform atomic property changes from another thread than the one

This new API allows watching a few select Unix signals;

GLib historically has been designed to be "mostly" portable; there
are some functions only available on Unix like g_io_channel_unix_new(),
but these are typically paired with obvious counterparts for Win32.
However, as GLib is used not only by portable software, but components
targeting Unix (or even just Linux), there are a few cases where it
would be very convenient if GLib shipped built-in functionality.
This initial patch is a basic wrapper around pipe2(), including
fallbacks for older kernels. This pairs well with the
existing g_spawn_*() API and its child_setup functionality.
However, in the future, I want to add a signal() wrapper here,
complete with proxying the signal to a mainloop. I have initial code
for this, but doing it sanely (including factoring out gmain.c's
private worker thread), is a complex task, and I don't want to block
on that.

GProxyConnection is a class that was added for proxy support;
g_socket_client_connect() returns a GSocketConnection, but in some
cases (eg, encrypted SOCKS), GProxy might return a GIOStream that is
not a GSocketConnection. In that case, GSocketClient would wrap the
stream up in a GProxyConnection, which is a subclass of
GSocketConnection but uses the input/output streams of the wrapped
connection.
GTlsConnection is not a GSocketConnection, so it has the same problem,
so it will need the same treatment. Rename the class to
GTcpWrapperStream, and make it public, so people can extract the base
stream from it when necessary.

This adds "child source" support to GSource. A child source behaves
basically like a GPollFD; when you add a source to a context, all of
its child sources are added with the same priority; when you destroy a
source, all of its child sources are destroyed; and when a child
source triggers, its parent source's dispatch function is run.
Use cases include:
- adding a GTimeoutSource to another source to cause the source to
automatically trigger after a certain timeout.
- wrapping an existing source type with a new type that has
a different callback signature
- creating a source that triggers based on different conditions
at different times.

Timezone handling is complicated. Really complicated.
In order to simplify it a little bit, we need to expose the GTimeZone
structure.
First of all, we allow creating time zone information directly from the
offset and the DST state, and then pass it to the g_date_time_new_full()
constructor. We also need to clean up the mess that is UTC-vs.-localtime
for the other constructors.
We also allow creating a GTimeZone from the Olson zoneinfo database
names; a time zone created like this will be "floating": it will just
reference the zoneinfo file - which are mmap()'ed, kept in a cache and
refcounted. Once the GTimeZone has been associated with a GDateTime, it
will be "anchored" to it: the offset will be resolved, as well as the
DST state.

These functions are meant to replace the read_until() flavour, with the
following improvements:
- consistency between the synchronous and asynchronous versions as to
if the separator character is read (it never is).
- support for using a nul byte as a separator character by way of
addition of a length parameter which allows stop_chars to be treated
as a byte array rather than a nul-terminated string.
The read_until() functions are not yet formally deprecated, but a note
has been added to the documentation warning not to use them as they will
be in the future.
This is bug #584284.
Since we added g_object_notify_by_pspec(), an efficient way to install

should have a single function to take the static array of GParamSpecs

Bug #617691.
If sending a lot of data and/or the other peer is not reading it, then
socket buffers can overflow. This is communicated from the kernel by
returning EAGAIN. In GIO, it is modelled by g_output_stream_write()
and g_socket_send_message() returning G_IO_ERROR_WOULD_BLOCK.
It is also problematic that that we're using synchronous IO in the
shared GDBus IO thread. It means that one GDBusConnection can lock up
others.
It turns out that by porting from g_output_stream_write() to
g_output_stream_write_async() we fix the EAGAIN issue. For GSocket, we
still need to handle things manually (by creating a GSource) as
g_socket_send_message() is used.
We check the new behavior in Michael's producer/consumer test case (at
/gdbus/overflow in gdbus-peer.c) added in the last commit.
