Adding in an ha_end() call. This is the first part of the patch I and Monty have agreed on. In the future engines will have the option of shutting down more quickly via the panic call, or just shutting down during the unloading of a plugin. 


sql/handler.cc:
  Adding ha_end
sql/handler.h:
  Function declaration for ha_end()
sql/mysqld.cc:
  Adding ha_end call.
