D-Bus versions < 1.6.18 (i.e. all current versions) have a bug with the
path_namespace='/' match rule key. It should conceptually match everything,
but actually matches nothing. This results in no property change (or other)
signals being forwarded to the D-Bus client.
The work-around implemented in GDBusObjectManagerClient is to remove the
path_namespace match key if its value is ‘/’.
For the upstream D-Bus bug, see:
https://bugs.freedesktop.org/show_bug.cgi?id=70799https://bugzilla.gnome.org/show_bug.cgi?id=710726
As it turns out, we have examples of internal functions called
type_name_get_private() in the wild (especially among older libraries),
so we need to use a name for the per-instance private data getter
function that hopefully won't conflict with anything.
If we don't connect to the control proxy's 'g-signal' signal, we won't have
'object-added' or 'object-removed' signals. So, connect to the 'g-signal' not
only when there already is a name-owner, but always.

Allow GDBusObjectManagerClient to work on peer to peer DBus
connections. Don't require that a unique bus name is available
for the object manager, if the owned bus name is NULL.

If the GDBusObjectManagerClient doesn't get a name owner during its lifetime,
`on_control_proxy_g_signal' will never be connected to any signal, so we
shouldn't dump any warning in that case.

Otherwise we might collide with an interface called Connection.

This is for the same reason that GDBusProxy has its properties
prefixed with g-.

This is needed because the proxy may need to update its internal state
which a signal handler connected to the manager may rely on.

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).
In gio/, simply switch to using g_cclosure_marshal_generic().
