If we have an expected interface and receive a signal not mentioned in
the interface, simply drop it. This way, the application won't have to
check for the signal itself.

If the proxy has an GInterfaceInfo set, validate properties against it
so the application doesn't have to do it.

Looks like we forgot to ref the returned GVariant in
g_dbus_proxy_call_finish().
It's a good question why code using g_dbus_proxy_call() and
g_dbus_proxy_call_finish() worked in the first place - probably the
answer is that no-one really used these APIs.

This is really what (API) users expect from GDBusProxy - in
particular, mclasen and I ran into this problem while debugging a
upower issue, see
https://bugzilla.redhat.com/show_bug.cgi?id=624125
In a nutshell, the problem is that polkitd crashes while upower holds
a PolkitAuthority object (which in turns contains a GDBusProxy for the
well-known name org.freedesktop.PolicyKit1). This means that
subsequent calls on the PolkitAuthority (which is translated into
calls into the GDBusProxy) fails since :g-name-owner is NULL.
With this fix, we'll be requesting the bus daemon to launch polkitd
since we will start calling into org.freedesktop.PolicyKit1 as soon as
we notice that there is no owner for this name.
Unfortunately our test suite doesn't cover service activation so there
is no way to reliably test this. I will file a bug about this.

This is currently unused but will probably be useful in the
future. For example, we could have a _ARG0_IS_PATH to specify that
arg0 should be used for arg0path.
This commit breaks API and ABI. Users of
g_dbus_connection_signal_subscribe() will need to port to this new
version.

Also emit GDBusProxy::g-properties-changed when dropping (when the
name owner vanishes) or populating (when loading properties) the
property cache.

If we know the expected interface (e.g. :g-interface-info is set),
then we always warned when calling a method on a different
interface. Don't do that, there's no way the expected interface can
know anything about this method.

The GType for a GVariant is now a fundamental GType instead of a boxed
one so use the right marshaller.

When asynchronously acquiring the DBus connection, assume a reference to
the proxy object, to avoid destroying it in the middle of the operation.
See https://bugzilla.gnome.org/show_bug.cgi?id=621905
Allow constructing a GDBusProxy for well-known names as discussed here
http://mail.gnome.org/archives/gtk-devel-list/2009-October/msg00075.html
including test cases.
Make it possible to create a GDBusProxy for a GBusType instead of a
GDBusConnection. This requires G_BUS_TYPE_NONE so add that too.
Nuke g_bus_watch_proxy() since one can now more or less use GDBusProxy
for this.
Port gdbus-example-watch-proxy to this new API and include this
example in the GDBusProxy doc page.
Also nuke the GType parameter from the GDBusProxy constructors as
requested here: https://bugzilla.gnome.org/show_bug.cgi?id=621229
Also update the porting guide and other API docs for this change.
Also fix a bug in the signal dispatching code so each subscriber only
get notified once, not N times, for the same signal. Also add a test
case for this.

Fix proxy construction for objects with no properties in the case
where G_DBUS_PROXY_FLAGS_DO_NOT_LOAD_PROPERTIES isn't set.
The unfortunate side-effect here is that GDBusProxy can no longer be
used to test for "object existence", e.g. creating a GDBusProxy for
any path and interface will not fail. But that's not really a big
deal, if apps rely on that they are doing something very wrong.

This allows the caller to specify the reply type that they are expecting
for this call. If the reply comes back with the wrong type, GDBus will
generate an appropriate error internally.
- add a GVariantType * argument to g_dbus_connection_call() and
_call_sync().
- move the internal API for computing message types from introspection
data to be based on GVariantType instead of strings. Update users
of this code.
- have GDBusProxy pass this calculated GVariantType into
g_dbus_connection_call(). Remove the checks done in GDBusProxy.
- Update other users of the code (test cases, gdbus-tool, GSettings
tool, etc). In some cases, remove redundant checks; in some other
cases, we are fixing bugs because no checking was done where it
should have been.
Closes bug #619391.
There's no need to re-build the a{sv} array, just get it right out of
the parameters. Also avoid some string copies.
