Xfconf ported to GDBus

[Ali Abdallah]

Dear all,

In the last commit I believe that I have fixed some/all major issues 
with libxfconf, it should be working fine now.
However, this does not mean that you can use the new version of xfconf 
with your actual xfce installation. There are things to be fixed in 
xfsettings and xfce4-panel, for example.

Precisely, there is no more XFCONF_TYPE_G_VALUE_ARRAY (which is a 
dbus_g_type_get_collection). Simply GPtrArray/G_TYPE_PTR_ARRAY should be 
used instead.

I'll have to bump the version of libxfconf-0 to libxfconf-1, to avoid 
conflict.

For reference I write down where XFCONF_TYPE_G_VALUE_ARRAY is used

xfce4-settings in
xfsettingsd/pointers.c:50  #define XFCONF_TYPE_G_VALUE_ARRAY 
(dbus_g_type_get_collection ("GPtrArray", G_TYPE_VALUE))

xfce4-panel in
common/panel-xfconf.c:164  type = dbus_g_type_get_collection 
("GPtrArray", G_TYPE_VALUE);
common/panel-dbus.h:37  dbus_g_type_get_collection ("GPtrArray",

These fixes can be easily implemented. There might be also other modules 
that need to be fixed as well.

Cheers,
Ali

PS: I was counting on porting a couple of modules, but unfortunately due 
to unexpected work position change, I will be very busy in the next 
coming months. I'll try to contribute as much as I can.
