If you want to share a debug category across more than one compilation
unit, instead of using GST_DEBUG_CATEGORY_STATIC, define the category using
GST_DEBUG_CATEGORY in one compilation unit and reference it using
GST_DEBUG_CATEGORY_EXTERN in the other units (e.g. via the element's header
file).

You still need to define GST_CAT_DEFAULT in all compilation units.
