sql/sql_select.cc:
  If we use subqueries, we can have double-free of tmp_table_param.copy_field
  in JOIN::destroy and in JOIN::join_free because.

sql/sql_select.cc:
  According to the conclusion made in the previous patch, we can widen
  the range of cases when JOINs are fully freed early, and include 
  subqueries to it.

sql/sql_select.cc:
  This assert is not relevant because:
  - the correct assert is DBUG_ASSERT(! (full && sl->uncacheable)) 
    (prevents freeing of uncacheable JOINs), it breaks view.test
  - it seems we can free internal JOINs, even if they are uncacheable:
    if the top level join is evaluated, we're not going to need  the
    internal joins any more

The reason it happened was that both, JOIN::cleanup() and JOIN::join_free(),
went over all nested joins and called cleanup/join_free for them.
For that:
- split recursive and non-recursive parts of JOIN::cleanup() and
JOIN::join_free()
- rename JOIN::cleanup to JOIN::destroy, as it actually destroys its
  argument
- move the recursive part of JOIN::cleanup to st_select_lex::cleanup
- move the non-recursive part of JOIN::join_free to the introduced
  method JOIN::cleanup().


sql/sql_lex.h:
  Add st_select_lex::cleanup, a counterpart of st_select_lex_unit::cleanup()
sql/sql_select.cc:
  - remove two unused arguments from return_zero_rows
  - split JOIN::join_free and JOIN::cleanup to recursive and non-recursive
    parts.
  - note, the assert in JOIN::join_free _does_ fail in having.test.
    We have two options: a) propagate `full' flag to the nested joins.
    We did it before, and this patch didn't change it. If so, we 
    can end up cleaning up an uncacheable JOIN (that is, the join that
    we might need again).
    b) evaluate own 'full' flag on every level. In this case, we might
    end up with tables freed in mysql_unlock_read_tables, but not
    cleaned up properly, and this may be even worse. The test suite
    passes with both approaches, but not with the assert.
sql/sql_select.h:
  - declarations for JOIN::cleanup() and JOIN::join_free()
sql/sql_union.cc:
  Add st_select_lex::cleanup, a counterpart of st_select_lex_unit::cleanup():
  move the recursive part of JOIN::cleanup to it.
