exit-on-close for a DBus connection is a completely normal thing. On
a regular GNOME login, gdm retains the X server, but terminates the
session login bus and associated helpers like gnome-settings-dameon,
the a11y tools, etc.
I've seen several downstream reports of confusion as to what these
apparent error messages mean in the system log. It doesn't help
that they're so obtuse.
We're also printing them to stderr, when this is not an error.
The reason this was introduced is presumably some people were confused
as to why their process exited when the system bus did. But the
solution for that I believe is documentation, not printing stuff to
everyone's system log in normal operation.

The previous commit introduced a possible memory leak in cases
where we get a G_IO_ERROR_CLOSED error. Make sure to always
free an error, if we got one.

There are real world cases where emitting signals can fail, such
as if the DBus connection closes. Asserting and aborting the process
in these cases is just plain lazy.
Ignore the errors when the connection is closed, and turn the
others into warnings.

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
https://bugzilla.gnome.org/show_bug.cgi?id=750282
A signal accumulator can return TRUE to continue signal emission, and
FALSE to stop signal emission. handle-local-options callbacks can return
« return a non-negative option if you have handled your options and
want to exit the process ».
Currently, g_application_handle_local_options_accumulator (the
accumulator for the handle-local-options signal) returns TRUE on
non-negative return value (ie continue signal emission), and returns
FALSE on negative return values (ie when the default option processing
should continue).
This return value seems backward as on >= 0 values, subsequent
handle-local-options callbacks could overwrite the 'exit request' from
the handler, while on < 0 values, the handle-local-options processing
could end up early if several callbacks are listening for this signal.
In particular, the default handler for this signal
(g_application_real_handle_local_options) always returns -1 and will
overwrite >= 0 return values from other handlers.
This commit inverts the check so that signal emission stops early when
one of the handle-local-options callbacks indicates it wants processing
to stop and the process to exit.

We already have start, stop and is_active methods, but turning it
into a real property is useful for a few reasons:
- it allows us to bind the property to an UI or a setting
- it allows us to get notified when the state changes
- it allows us to instantiate objects directly in the stopped state

Also add g_app_info_get_fallback_for_type() and
g_app_info_get_recommended_for_type() as proxies for
g_app_info_get_all_for_type(), until gcontenttype support is improved.
This code was out of date with current coding practices.
Nowadays it's common to receive file descriptors over environment
variables from other processes like systemd. The unit files that
control these file descriptors are configurable by sysadmins.
It is not (necessarily) a programmer error when g_socket_details_from_fd()
is called with a file descriptor that is not a socket. It can also
be a system and/or configuration error.

In 4e7d22e268, deleting the file was moved
after the assertion which checks for the changed event that results from
it being deleted. This is the wrong way around and makes the assertion
fail.
Move the deletion back up before we check the condition. delete_app is
no longer an idle callback so it can be made void. The change
notification might come in when the loop isn't running now, so don't try
to quit if it isn't running. In this case we'll wait for the three
second timeout and the test will still pass.

When a task is cancelled, we want to move it to the front
of the queue - our sort function does that for us, but there
is no need to resort the entire queue here, we can just
move the one item and be done with it. This uses just-introduced
threadpool api for this purpose.

Make sure to initialize the notification backend in
g_application_withdraw_notification() the same way as is done in
g_application_send_notification().
This makes it possible for an app to withdraw notifications it has sent
in a previous execution of the application.

We need to be more careful when we try to assign values to gpointers, so
that means we have to assign the value to the properly-dereference
gpointer, so that the assigned value will be retained after the function
returns. This code will be dropped soon, but it is done for XP
compatibility's sake for 2.44.
Should fix the issue reported in bug 730352 comment #24.
For performance reasons we should always try to send or
receive our messages first and only wait for more space
or data to become available if we get an EAGAIN (and
are in blocking mode).

This can be handy when you want to change the sense of a toggle
in the UI without rewriting the underlying logic. Currently, this
is just exposed as a construct-only property. We may add a
convenience wrapper or a special !property syntax for this later.

This is the right thing to do for the "a session is a user-session"
model implemented in dbus 1.9.14, which is described in
<http://lists.freedesktop.org/archives/dbus/2015-January/016522.html>.
It also resembles sd-bus' behaviour, although sd-bus will only try
kdbus and XDG_RUNTIME_DIR/bus, and never runs dbus-launch.
On systems following the more traditional "a session is a login-session"
model, X_R_D/bus won't exist, so it is harmless to check for it before
falling back to X11 autolaunching. Again, this matches the behaviour
of current libdbus and sd-bus versions.
Now that we do this, g_test_dbus_unset() needs to clear XDG_RUNTIME_DIR
as well as everything else.

This only alters what happens if we specifically connect to
"autolaunch:", for instance via "DBUS_SESSION_BUS_ADDRESS=autolaunch:".
We will still potentially try other platform-specific things if
DBUS_SESSION_BUS_ADDRESS is unset. There are currently no other
platform-specific things, so there is no practical difference yet,
but I'm about to add a more-preferred fallback path before autolaunch.
This matches libdbus' behaviour and the D-Bus Specification, in which
the autolaunch: transport specifically means X11 autolaunch
(as implemented by "dbus-launch --autolaunch") on Unix, or a
shared-memory-based protocol on Windows. Other platform-specific
transports or default/fallback modes, including launchd on Mac OS X
and XDG_RUNTIME_DIR/bus on Unix, are not part of "autolaunch:".
It's rather unfortunate that the same name means two different
platform-specific mechanisms, specific to different platforms -
if they were added today I'd call them x11: and windows-shm: or
something - but it's been like this since 2007 so it's too late now.

Currently, applications using g_application_add_main_option_entries()
won't get translated entries in --help output. We need to call
g_option_group_set_translation_domain() with a NULL domain to ensure that the
default application gettext domain (ie the one passed to the
textdomain() call) will be used for the main entries passed by the
application.
If we want to allow more flexibility on which gettext domain should be
used for these entries, new API will be needed.

Add a new section to the main GSettings documentation which documents

Some of this material was adapted from the migrating-gconf.xml guide.
