Set bindir, datadir & others if --basedir is given. This ensures that one only has to set basedir in [mysqld] group when moving a binary installation to a not default polace
Use for now safe_mysqld by default. (unless use-manager is set in the [mysql.server] option in my.cnf)
Search first for defaults files in basedir and then in datadir (like mysqld_safe)

  Added a test case for bug #9516.
item_subselect.h:
  Fixed bug #9516.
  The bug was due to that fact that the class Item_subselect
  inherited the generic implementation of the function
  not_null_tables that was not valid for the objects
  of this class. As a result evaluation of the
  not_null_tables attribute was not correct for subqueries.
  This caused invalid transformations of outer joins into
  inner joins.

  Added a test case for bug #9338.
sql_select.cc:
  Fixed bug #9338.
  When an occurence of a field reference has to be replaced
  by another field reference the whole Item_field must be
  replaced.
item.cc:
  Fixed bug #9338.
  The method Item_field::replace_equal_field_processor was
  replaced by Item_field::replace_equal_field. The new method
  is used to replace the occurences of Item_field objects.
item.h:
  Fixed bug #9338.
  The virtual function replace_equal_field_processor was replaced
  by replace_equal_field. The latter is supposed to be used as a
  callback function in calls of the method transform.
