This pre-requisite patch refactors the code for dropping tables, used
by DROP TABLE and DROP DATABASE. The patch moves the code for acquiring
metadata locks out of mysql_rm_table_part2() and makes it the
responsibility of the caller. This in preparation of changing the
DROP DATABASE implementation to acquire all metadata locks before any
changes are made. mysql_rm_table_part2() is renamed
mysql_rm_table_no_locks() to reflect the change.
The ALTER PARTITION and SELECT seemed to be deadlocked
when having innodb_thread_concurrency = 1.
Problem was that there was unreleased latches
in the ALTER PARTITION thread which was needed
by the SELECT thread to be able to continue.
Solution was to release the latches by commit
before requesting upgrade to exclusive MDL lock.
Updated according to reviewers comments (3).
mysql-test/r/partition_innodb.result:
updated test result
mysql-test/t/partition_innodb.test:
added test
sql/sql_partition.cc:
Moved implicit commit into mysql_change_partition
so that if latches are taken, they are always released
before waiting on exclusive lock.
sql/sql_table.cc:
refactored the code to prepare and commit
around copy_data_between_tables, to be able
to reuse it in mysql_change_partitions
sql/sql_table.h:

This patch introduces two key changes in the replication's behavior.
Firstly, it reverts part of BUG#51894 which puts any update to temporary tables
into the trx-cache. Now, updates to temporary tables are handled according to
the type of their engines as a regular table.
Secondly, an unsafe mixed statement, (i.e. a statement that access transactional
table as well non-transactional or temporary table, and writes to any of them),
are written into the trx-cache in order to minimize errors in the execution when
the statement logging format is in use.
Such changes has a direct impact on which statements are classified as unsafe
statements and thus part of BUG#53259 is reverted.

Fixing the partitioning specifics after TRUNCATE TABLE in
bug-42643 was fixed.
Reorganize of code to decrease the size of the giant switch
in mysql_execute_command, and to prepare for future parser

DATABASE with open HANDLER"
Remove LOCK_create_db, database name locks, and use metadata locks instead.
This exposes CREATE/DROP/ALTER DATABASE statements to the graph-based
deadlock detector in MDL, and paves the way for a safe, deadlock-free
implementation of RENAME DATABASE.
Database DDL statements will now take exclusive metadata locks on
the database name, while table/view/routine DDL statements take
intention exclusive locks on the database name. This prevents race
conditions between database DDL and table/view/routine DDL.
(e.g. DROP DATABASE with concurrent CREATE/ALTER/DROP TABLE)
By adding database name locks, this patch implements
WL#4450 "DDL locking: CREATE/DROP DATABASE must use database locks" and
WL#4985 "DDL locking: namespace/hierarchical locks".
The patch also changes code to use init_one_table() where appropriate.
The new lock_table_names() function requires TABLE_LIST::db_length to
be set correctly, and this is taken care of by init_one_table().
This patch also adds a simple template to help work with
the mysys HASH data structure.
Most of the patch was written by Konstantin Osipov.
This patch:
- Moves all definitions from the mysql_priv.h file into
header files for the component where the variable is
defined
- Creates header files if the component lacks one
- Eliminates all include directives from mysql_priv.h
- Eliminates all circular include cycles
- Rename time.cc to sql_time.cc
- Rename mysql_priv.h to sql_priv.h
