    Change occurences of assert (0) into babl_fatal()
    
    babl_fatal() is the more appropriate method to die upon failure, so
    all instances of assert (0) have been changed into babl_fatal() with
    some attempt of an error message.
    
    In this process, the babl_fish_process() method was refactored into
    using the existing case statement.
    
    Bug #589027.
