    - Remove unneeded #includes;
    - "Once-only" test not needed in proto_reg_handoff..();
    - Set COL_PROTOCOL, clear COL_INFO at the begining of the dissector
       before fetching data from the tvb;
    - Use tvb_reported_length;
    - Use col_set_str/col_append_str where appropriate;
    - Zigbee --> lwm;
    - Fix typo;
    - Reformat some whitespace for consistency.

    ToDo:
    - Review use of col_...() and expert...() under 'if (tree)';
    - Review use of col_clear(..., COL_INFO) after text already added to
COL_INFO;
    - Review certain tvb fetches to ensure  no fetches using a negative offset;
