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.

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.
