      Fixed LP bug #694443. · 18dc64ec
      Igor Babaev authored
      One of the hash functions employed by the BNLH join algorithm
      calculates the the value of hash index for key value utilizing
      every byte of the key buffer. To make this calculation valid
      one has to ensure that for any key value unused bytes of the 
      buffer are filled with with a certain filler. We choose 0 as
      a filler for these bytes.
      
      Added an optional boolean parameter with_zerofill to the function
      key_copy. If the value of the parameter is TRUE all unused bytes
      of the key buffer is filled with 0.

      Fixed LP bug#694092. · d9a81475
      Igor Babaev authored
      In some cases the function make_cond_for_index() was mistaken
      when detecting index only pushdown conditions for a table: 
      a pushdown condition that was not index only could be marked
      as such.
      It happened because the procedure erroneously used the markers
      for index only conditions that remained from the calls of
      this function that extracted the index conditions for other 
      tables.
      Fixed by erasing index only markers as soon as they are need
      anymore.

      Lifted the limitation that hash join could not be used over 
      varchar fields with non-binary collation.

      Fix LP BUG#685411 · 4f28dcbe
      unknown authored
      Analysis:
      The assert failed because st_select_lex::print() was called for subqueries
      as follows:
      
      Item_subselect::print() ->
        subselect_single_select_engine::print() -> st_select_lex::print()
      
      It was Item_subselect::fix_fields() that set the thd by calling set_thd(),
      so when this print() was called before fix_fields(), subselect_engine::thd
      was NULL.
      
      Solution:
      The patch makes all constructors of all subselect_engine classes to take
      a THD parameter. The default subselect_single_select_engine engine is created
      early during parse time, in the Item_subselect::init call, so we pass the
      correct THD object already at this point.
