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.
