BUG#32943: Fixed buggy lock handling of ALTER TABLE for partitioning

Browse Source 
mysql-test/r/partition_range.result:
  Added new test cases for lock tables and ALTER TABLE for
  partitions, also added a test case with a trigger.
mysql-test/t/partition_range.test:
  Added new test cases for lock tables and ALTER TABLE for
  partitions, also added a test case with a trigger.
sql/mysql_priv.h:
  Added WFRM_KEEP_SHARE for use of code not to be used otherwise
sql/sql_partition.cc:
  Removed get_name_lock and release_name_lock, use
  close_data_files_and_morph_locks which leaves an
  exclusive name lock after completing.
  Reopen table after completing if under lock tables
  Updated comments
sql/sql_table.cc:
  Ensure that code to set partition syntax isn't used other than
  when specifically asked to do it.
