    fixed view fields names check and generation (changed after Trudy review: underlying field names treat as user set ones) (BUG#7448)
    
    
    mysql-test/r/view.result:
      test of view field names generation
    mysql-test/t/view.test:
      test of view field names generation
    sql/item.cc:
      add a flag that indicates that the name of the item was an auto-generated one and so can be changed in a view
    sql/item.h:
      add a flag that indicates that the name of the item was an auto-generated one and so can be changed in a view
      layout fixed
    sql/item_func.cc:
      line made less then 80 columns
    sql/sql_view.cc:
      fixed checking of duplicates of view fields:
      1) case-insensitive system charset/collation is used now to compare view filds
      2) in case if the duplicate field name was of an auto-generated one, we create another unique name for it
    sql/sql_yacc.yy:
      add a flag that indicates that the name of the item was an auto-generated one and so can be changed in a view
