data": remove the fix for another bug (8807) that
added OUTER_REF_TABLE_BIT to all subqueries that used a placeholder
to prevent their evaluation at prepare. As this bit hanged in 
Item_subselect::used_tables_cache for ever, a constant subquery with
a placeholder was never evaluated as such, which caused wrong 
choice of the execution plan for the statement.
- to fix Bug#8807 backport a better fix from 5.0
- post-review fixes.

of stored routines definitions even if we already have some tables open and
locked. To avoid deadlocks in this case we have to put certain restrictions
on locking of mysql.proc table.

This allows to use stored routines safely under LOCK TABLES without explicitly
mentioning mysql.proc in the list of locked tables. It also fixes bug #11554
"Server crashes on statement indirectly using non-cached function".

  added out of range handling

  adding test case
sql_table.cc:
  sql_table.cc:
  - do not create a new item when charsets are the same
  - return ER_INVALID_DEFAULT if default value cannot
    be converted into the column character set.
item.cc:
  - Allow conversion not only to Unicode,
    but also to and from "binary".
  - Adding safe_charset_converter() for Item_num
    and Item_varbinary, returning a fixed const Item.
