Bug#53676: Unexpected errors and possible table

Browse Source 
corruption on ADD PARTITION and LOCK TABLE
Bug#53770: Server crash at handler.cc:2076 on
           LOAD DATA after timed out COALESCE PARTITION

5.5 fix for:
Bug#51042: REORGANIZE PARTITION can leave table in an
           inconsistent state in case of crash
Needs to be back-ported to 5.1

5.5 fix for:
Bug#50418: DROP PARTITION does not interact with
           transactions

Main problem was non-persistent operations done
before meta-data lock was taken (53770+53676).
And 53676 needed to keep the table/partitions opened and locked
while copying the data to the new partitions.

Also added thorough tests to spot some additional bugs
in the ddl_log code, which could result in bad state
between the .frm and partitions.

Collapsed patch, includes all fixes required from the reviewers.

  partitioned innodb test that require debug builds
mysql-test/suite/parts/t/partition_debug_myisam-master.opt:
  opt file for using with crashing tests of partitioned myisam
mysql-test/suite/parts/t/partition_debug_myisam.test:
  partitioned myisam test that require debug builds

  added test case
sql/sql_base.cc:
  Moved alter_close_tables to sql_partition.cc
sql/sql_base.h:
  removed some non existing and duplicated functions.
sql/sql_partition.cc:
  fast_alter_partition_table:
  Spletted abort_and_upgrad_lock_and_close_table
  to its parts (wait_while_table_is_used and
  alter_close_tables) and always have
  wait_while_table_is_used before any persistent
  operations (including logs, which will be executed
  on failure) and alter_close_tables after
  create/read/write operations and before
  drop operations.
  
  moved alter_close_tables here from sql_base.cc
  
  Added error injections for better test coverage.
  
  write_log_final_change_partition:
  fixed a log_entry linking bug (delete_frm was not
  linked to change/drop partition)
  and drop partition must be executed before
  change partition (change partition can rename a
  partition to an old name, like REORG p1 INTO (p1,p2).
  
  write_log_add_change_partition:
  need to use drop_frm first, and relinking that entry
  and reusing its execute entry.
sql/sql_table.cc:
  added initialization of next_active_log_entry.
sql/table.h:
  removed a duplicate declaration.
