extmod/btstack: Update BTstack bindings to work with latest BTstack.

Browse Source 
The following multi-tests pass (eg with PYBD_SF6+LEGO_HUB_NO6):

    ble_gap_advertise.py
    ble_gap_connect.py
    ble_gap_device_name.py
    ble_gattc_discover_services.py
    ble_gatt_data_transfer.py
    perf_gatt_char_write.py
    perf_gatt_notify.py
    stress_log_filesystem.py

These are the same tests that passed prior to this BTstack update.

Also tested on the unix port using H4 transport.
