socket->priv->connected was only being set if g_socket_connect()
succeeded right away; in the case where it returns G_IO_ERROR_PENDING,
it never got set. Fix that by having g_socket_check_connect_result()
set it on success.
Otherwise, we may run into trouble as opening a peer-to-peer
connection uses a socket client, which uses a proxy resolver
which may end up using gsettings, whose dconf backend may end
up using the session bus to talk to dconfd...
Also add convenience _with_unix_fd_list variants to GDBusConnection,
GDBusProxy and GDBusMethodInvocation types to easily support this.

This function implements the following logic:
if (g_variant_is_floating (value))
g_variant_ref_sink (value);
which is used for consuming the return value of callbacks that may or
may not return floating references.
This patch also replaces a few instances of the above code with the new
function (GSettings, GDBus) and lifts a long-standing restriction on the
use of floating values as the return value for signal handlers by
improving g_value_take_variant().

-In gio/Makefile.am, the name for one of the filters for capturing the

GAction is a read-only interface (as is visible by the lack of _set() functions
on its API). The properties on the interface currently force implementors to
support writing of the properties at construct time, however.
Lift that restriction.
Take advantage of this from GSimpleAction by nuking the set_property
function and setting the fields directly in the constructor.
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().
To help cross compilation, don't use glib-genmarshal in our
build. This is easy now that we have g_cclosure_marshal_generic().
In gobject/, add gmarshal.[ch] to git (making the existing entry
points stubs).

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
easily be fixed by adding a lock to the skeleton object.
In addition to fixing this race, also move the code for setting up the
idle handler to a class handler for the GObject::notify signal. This
change allows use of g_object_freeze_notify() and g_object_thaw_notify()
to perform atomic property changes from another thread than the one
that the skeleton was created in.

Don't drop resets from a GDelayedSettingsBackend when the writability
changes. Resets will always succeed, even against non-writable keys and
some people (gnome-screensaver) are using them in a way that they would
want them not to be forgotten.
This can easily happen if the owner of the remote object vanishes. Of
course, when that happens, user code is already notified (by e.g. the
notify::g-name-owner signal) so it can avoid using the proxy but
requiring that is a bit harsh. IOW, before this patch this critical
error was printed
GLib-GIO-CRITICAL **: g_dbus_gvariant_to_gvalue: assertion `value != NULL' failed
when that happened. With this patch, we just avoid setting the GValue
so the user will get the default value for its type instead. So, for
example, if the user code is getting a GVariant property on such a
defunct proxy, then he gets a NULL back. So unless said user code
checks the return value, criticals will still be printed if the NULL
GVariant is used for anything interesting.

The code generator sprinkles a few asserts in its output of the form:
g_assert (prop_id - 1 >= 0 && prop_id - 1 < %d);\n
prop_id is unsigned, though, so this generates a compiler warning for
me.
This commit changes the code to merely check for prop_id != 0 instead of
prop_id - 1 >= 0
.. and add a C setter to do this. Also make the C getter return a
reference since the property may be set from another thread. Also
change the constructor to _not_ take a GDBusConnection since this is
something you almost always want to do _after_ creating it. The
API/ABI break is fine as there has never been a GLib release with this
type.

_GNU_SOURCE must be defined before including any other (system)
header, so defining it in glib-unix.h (and hoping no one has included
anything else before that) is wrong. And the "#define _USE_GNU"
workaround for this problem in gnetworkingprivate.h is even wronger
(and still prone to failure anyway due to single-include guards).
Fix this by defining _GNU_SOURCE in config.h when building against
glibc. In theory this is bad because new releases of glibc may include
symbols that conflict with glib symbols, which could then cause
compile failures. However, most people only see new releases of glibc
when they upgrade their distro, at which point they also generally get
new releases of gcc, which have new warnings/errors to clean up
anyway.

When an old pre-thread-default-context API that takes an explicit
GMainContext wants to call a gio API, it must call
g_main_context_push_thread_default() before, and
g_main_context_pop_thread_default() after the gio call, so that the
gio method will return its result to the desired GMainContext.
But this fails for methods like g_socket_client_connect_async() that
make a chain of multiple async calls, since the pushed/popped context
will only affect the initial call.
Fix this by having GSimpleAsyncResult itself push/pop the context
around the callback invocation, so that if the callback queues another
async request, it will stay in the same context as the original one.

A fairly typical pattern is to have code that does
foo_set_bar (object, "");
if (some_condition)
{
foo_set_bar (object, "yes");
}
where some_condition is often true every time @object is updated.
With this code, bar is essentially always "yes" but because of how
gdbus-codegen works, useless PropertiesChanged events got scheduled
and sent out. With this patch, we avoid that by always keeping the
original value around and comparing it only when we deem it's time to
send out the ::PropertiesChanged signal (typically in an idle but can
be forced by the user via flush()).
Also add a test case for this.

Call g_settings_sync() just before g_applcation_run() returns. This is
really the correct thing to do in every case that you're using GSettings
and it prevents every single application from having to do it for
themselves.
Closes bug #647419.
If GSettings is uninitialised then g_settings_sync() should very
obviously just return right away (rather than attempting to initialise
GSettings first).
Add a flag to essentially short-circuit g_application_register(). The
application makes no attempt to acquire the bus name or check for
existing instances with that name. The application is never considered
as being 'remote' and all requests are handled locally.
