BUG#19122: MySQL Server crashes when ALTER TABLE t1 REBUILD PARTITION on InnoDB table

Browse Source 
mysql-test/r/partition.result:
  New test case
sql/lock.cc:
  Added new flag to lock_table_name to ensure we get proper name lock even when we already have lock on table.
sql/mysql_priv.h:
  Added new flag to lock_table_name to ensure we get proper name lock even when we already have lock on table.
  Added table_list to ALTER_PARTITION_PARAM_TYPE and changed some const char * to char*
sql/sql_base.cc:
  Added new flag to lock_table_name to ensure we get proper name lock even when we already have lock on table.
  Added table_list to ALTER_PARTITION_PARAM_TYPE and changed some const char * to char*
sql/sql_partition.cc:
  New methods to
  1) Get a name lock even when we already have one
  2) New method that unlocks table and closes the handlers.
  3) Release name lock
  Integrated those new methods to ensure that handlers are unlocked and closed when drop or
  rename is called on them. There is still some work to update the comments to reflect the
  last changes.
