  merge with 4.1
  Fixed test case to not use 'if exists' when it shouldn't
mysql-test/t/range.test:
  merge with 4.1
  Added missing drop table
sql/ha_ndbcluster.cc:
  merge with 4.1
  Simple optimization: use max() instead of ? :
sql/item_func.cc:
  merge with 4.1
  (Added back old variable names for easier merges)
sql/opt_range.cc:
  merge with 4.1
  Removed argument 'parent_alloc' from QUICK_RANGE_SELECT as this was not used
  Added assert if using QUICK_GROUP_MIN_MAX_SELECT with parent_alloc as the init() function can't handle this
  Changed back get_quick_select_for_ref() to use it's own alloc root becasue this function may be called several times for one query
sql/sql_handler.cc:
  merge with 4.1
  change variable 'err' to 'error' as same function had a label named 'err'
sql/sql_update.cc:
  Use multi-update code from 5.0 instead of 4.1
  We will fix the locking code shortly in 5.0 to be faster than in 4.1
