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 base/gst-libs 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.

Fix newsegment event handling a bit. We need to
cache the first newsegment event, because we can't
adjust offsets yet when we get it, as we don't
know the size of the tag yet for sure at that point.
Also do some minor cleaning up here and there and add
some debug statements.
