Prepare a new seamless segment for emission downstream. This function must
only be called by derived sub-classes, and only from the #GstBaseSrcClass::create function,
as the stream-lock needs to be held.
The format for the new segment will be the current format of the source, as
configured with gst_base_src_set_format()
