    fontconfig: keep track of, and free, our configuration · f564aefb

    Inspite of claims to the contrary in fontconfig 2.11 changes log,
    FontConfig is really not thread-safe, since it uses atomic pointers
    instead of proper reference counting. Consequently, LibVLC cannot
    safely call FcFini() - it could crash another thread using FontConfig
    concurrently.
    
    Using our own configuration has the benefit of not leaking related
    memory allocations, though it means that the LibVLC text renderer
    cannot share the configuration with other components in the same
    process.
    
    Note that there are still leaks within FontConfig. Specifically, the
    cache and the language/program default values are not freed, since that
    would require FcFini(). If you care in your application, call FcFini()
    after you have terminated all LibVLC instances.
