/*

  Mark range of selects and resolved identifier (field/reference) item as

  dependent



  SYNOPSIS

    mark_select_range_as_dependent()

    thd           - thread handler

    last_select   - select where resolved_item was resolved

    current_sel   - current select (select where resolved_item was placed)

    found_field   - field which was found during resolving

    found_item    - Item which was found during resolving (if resolved

                    identifier belongs to VIEW)

    resolved_item - Identifier which was resolved



  NOTE:

    We have to mark all items between current_sel (including) and

    last_select (excluding) as dependend (select before last_select should

    be marked with actual table mask used by resolved item, all other with

    OUTER_REF_TABLE_BIT) and also write dependence information to Item of

    resolved identifier.
