Make Low Level host demos use void pointers for the configuration descriptor, to prevent warnings when passed to the altered configuration descriptor parsing routines.

Added preprocessor checks to give a human readable error when the class drivers are used when the incompatible NO_STREAM_CALLBACKS compile time option is used.
