table to partitioned

Problem:
Crashed because usage of an uninitialised mutex when auto_incrementing
  a partitioned temporary table

Fix:
Only locking (using the mutex) if not temporary table.

  "Disabled plugin is provoking Valgrind error"
  If there are any auto-alloced string plug-in options, memory is
  allocated during the call for handle_options(). We must free this
  memory if we are not installing the plug-in.

Two cases in ha_partition::extra() was missing
(HA_EXTRA_DELETE_CANNOT_BATCH and HA_EXTRA_UPDATE_CANNOT_BATCH)

were accidentally removed during a previous rototill of this
code.  Fixes bug#27692.
  
While it can be argued we should strive to provide a 'secure by
default' installation, this happens to be the setup currently
documented in the manual as the default, so defer changes that
improve security out of the box to a co-ordinated effort later
on.
  
For now, make a note about the test databases and anonymous user
in mysql_install_db and recommend that mysql_secure_installation
be ran for users wishing to remove these defaults.
