    bug#23514050 Binlog data is incorrect for NDB table with virtual gcol

    In ndb_unpack_record() the "twin loop" iterating over fields and values must be
    modified, because values are present only for stored (not virtual) columns.

    In handle_data_event() the bitmask used with a binlog record should have bits
    set not for all columns, but only for all stored columns.

    Some refactoring is done to move logic from ha_ndbcluster_binlog.cc to ndb_share.cc
