    Fix use of undeclared core debug category symbols · a62c7bd5
    Tim-Philipp Müller authored
    libgstreamer currently exports some debug category
    symbols GST_CAT_*, but those are not declared in any
    public headers.
    
    Some plugins and libgstvideo just use GST_DEBUG_CATEGORY_EXTERN()
    to declare and use those, but that's just not right at
    all, and it won't work on Windows with MSVC. Instead look
    up the categories via the API.
