Add a GstControlBinding class. This is a preparation for making the
controlsources generate double valued control curves and do the gparamspec
mapping in the control binding. Now the API in GstObject is again mostly
for convenience.
This make the controller even more lightweight (no extra object, no extra lock,
less indirections). For object that don't use the controller the only 'overhead'
is a 3 unused fields in the gst_object structure.
Move the controller to gstobject as a simple delegate. The controller and
controlsource are not classes in core. The controlsources stay separate as a lib
for now. This way we can avoid the qdata lookups.
Also remove controller_init(). There is no more need to link to controller for
elements.
Also sanitize the API. We now have functions to add properties like we had
methods to remove that. That avoids then ref count hacks we had in _new.
