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 is possible now that we have better support for object path
arrays, see
http://git.gnome.org/browse/glib/commit/?id=19878998bc386db78614f1c92ff8524a81479c7b
Note that this breaks the ABI of generated code but since
gdbus-codegen(1) has never yet been in a stable GLib release, this is
fine.

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().
... otherwise we might end up using the worker after it has been
freed. Reported by Dan Winship and Colin Walters.
This fix uncovered a bug in the /gdbus/nonce-tcp test case so "fix"
that as well to use a better way of having one thread wait for another
(using quotes for the word "fix" since it's pretty hackish to
busy-wait in one thread to wait for another).

These will validate the resulting line, and throw a conversion error.
In practice these will likely be used by bindings, but it's good
for even C apps too that don't want to explode if that text file
they're reading into Pango actually has invalid UTF-8.

This avoids the generated types (e.g. ExampleAnimal, ExampleCat,
ExampleObject and ExampleObjectManagerClient) being referenced in the

.. 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.

Specific changes
- Use get_type(), not get_gtype() for the GType function
- so we need to use the lower-case name type_ for properties called type
- Don't return a function pointer, just make the function returned
available instead
- Add (type) annotations in constructors so g-ir-scanner detects them as such
- Add (transfer none) annotations to property getters
- Add (out) annotations to D-Bus method call functions

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.

Older versions of libdbus would let you construct an invalid
DBusMessage, but that's a bug, which will be fixed in 1.4.8/1.5.0.
Instead, construct a valid message of the same length, then replace
substrings in the serialized blob with their invalid counterparts.

Several flaws were pointed out by Shaun McCance. We were
leaking handled arguments, and we were mishandling the last
argument, and we were actually skipping arguments too.

When using GOption to handle commandlines, we need to disable
the builtin help handling, since it calls exit(). Also mention
this particular pitfall in the docs.
We were getting our length zero, yet NULL-terminated arrays in
a twist in some places. Stop passing around ignored length arguments
at the same time.

This commit also changes (maintaining compatibility) the way
user-specified default applications are stored (as in, those for which
g_app_info_set_as_default_for_type() has been called.
We now store the default application for a content type in a new group
in the mimeapps.list keyfile, and "Added Associations" tracks only the
applications that have been added by the user, following a
most-recently-used first order.
This is useful in GtkAppChooser-like widgets to pre-select the last used
application when constructing a widget.

This adds an extension point for TLS connections to gio, with a
gnutls-based implementation in glib-networking.
Full TLS support is still a work in progress; the current API is
missing some features, and parts of it may still be changed before
2.28.

When interfacing with APIs that expect unix-style async I/O, it is
useful to be able to tell in advance whether a read/write is going to
block. This adds new interfaces GPollableInputStream and
GPollableOutputStream that can be implemented by a GInputStream or
GOutputStream to add _is_readable/_is_writable, _create_source, and
_read_nonblocking/_write_nonblocking methods.
Also, implement for GUnixInput/OutputStream and
GSocketInput/OutputStream
https://bugzilla.gnome.org/show_bug.cgi?id=634241
Otherwise, attempting to create a GSocketConnection from the socket
will likely return the wrong type, since the protocol won't match any
of the registered subtypes.
Also add the start of a GSocket test program (from davidz).
