    PangoLanguage: Fix clang -Wcast-align warnings
    
    Clang complains when casting char* to PangoLanguage* and -Wcast-align
    set. We only cast it to char* to get the proper address for the private
    struct though, so just cast to void* afterwards.
    
    Except for the case that was stuffing PangoLanguage* sized elements into
    a GArray. Just use a GPtrArray there.
