* As of the LSCP 1.2 working draft document, added
  some missing client interface functions:
    lscp_get_total_voice_count();
    lscp_get_total_voice_count_max();
  and for the new MIDI instrument mapping features:
    lscp_map_midi_instrument();
    lscp_unmap_midi_instrument();
    lscp_get_midi_instruments();
    lscp_get_midi_instrument_info();
    lscp_clear_midi_instruments();
