Browse Source 
After review changes


mysql-test/r/ndb_partition_key.result:
  Fixed result file
sql/ha_ndbcluster.cc:
  Fixed interface to create_handler_files
sql/ha_ndbcluster.h:
  Fixed interface to create_handler_files
sql/ha_partition.cc:
  Fixed interface to create_handler_files and made it two-stage for rename
  Removed print_error and now it's used by MySQL Server parts instead
sql/ha_partition.h:
  Fixed interface to create_handler_files
sql/mysql_priv.h:
  Fixed error injects
  Externalised Global DDL log mutex
  Some interface changes
sql/mysqld.cc:
  Moved close of DDL log until all user threads been closed
sql/sql_base.cc:
  Interface changes
sql/sql_partition.cc:
  Moved print_error to mysql server part
sql/sql_table.cc:
  Lots of after review changes
sql/table.cc:
  Fixed upgrade code
