Since we started depending on GLib 2.44, we can be sure this macro is
defined (it will be a no-op on compilers that don't support it). For
plugins we should just start using `G_DECLARE_FINAL_TYPE` which means
we no longer need the macro there, but for most types in core we don't
want to break ABI, which means it's better to just keep it like it is
(and use the `#ifdef` instead).
We need different export decorators for the different libs.
For now no actual change though, just rename before the release,
and add prelude headers to define the new decorator to GST_EXPORT.
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.
