Removing unguarded read of slave_running field from inside
terminate_slave_threads(). This could cause premature exit in the event
that the slave thread already were shutting down, but isn't finished yet.

The fields slave_running, io_thd, and sql_thread are guarded by an
associated run_lock. A read of these fields were not guarded inside
terminate_slave_threads(), which caused an assertion to fire. The
assertion was removed, and the code reorganized slightly.

Update some tests in the "parts" suite, so they're skipped if the
requisite plugins are not present in the mysqld.

Bug #30316: Some "parts" tests fail because the server uses "--secure-file-priv"
Bug #30341: Test suite "parts" needs to be adapted to the new rules disallowing many functio
Bug #30408: Suite "parts" needs bug numbers updated
Bug #30411: Suite "parts" needs bug numbers updated: ER_UNIQUE_KEY_NEED_ALL_FIELDS_IN_PF
Bug #30576: part_supported_sql_func_innodb.test tries to LOAD DATA outside of var dir
Bug #30581: partition_value tests use disallowed CAST() function

Included are some general fixes to allow the "parts" test suite to be run
successfully.  This includes disabling a few tests or parts of tests,
cleaning up the test cases and their results, etc.  Basically, these tests
have not been run for some time, and had suffered some bit rot.

The bugs were fixed as a single changeset, because in some ways they depend
on each other.  I couldn't be sure I'd updated all the error codes (for
bugs 30408 and 30411) without also adapting to the new allowed functions
rules (bug 30341), and vice versa.

table->record[1] buffers inside Rows_log_event::find_row() function. 
The patch fixes this.

A local variable may be used uninitialized in 
ha_partition::get_auto_increment().  Initialize it properly.

MySQL replicates the time zone only when operations that involve
it are performed. This is controlled by a flag. But this flag
is set only on successful operation.
The flag must be set also when there is an error that involves
a timezone (so the master would replicate the error to the slaves).

  
  A test case was waiting for a fixed number of seconds for a specific 
  state of the slave IO thread to take place.
  Fixed by waiting in a loop for that specific thread state instead 
  (or timeout).

keep_files_on_create made a startup option

using TPC-B):
 
Problem: A RBR event can contain incomplete row data (only key value and
fields which have been changed). In that case, when the row is unpacked
into record and written to a table, the missing fields get incorrect NULL
values leading to master-slave inconsistency.
 
Solution: Use values found in slave's table for columns which are not given
in the rows event. The code for writing a single row uses the following 
algorithm: 

1. unpack row_data into table->record[0],
2. try to insert record,
3. if duplicate record found, fetch it into table->record[0],
4. unpack row_data into table->record[0],
5. write table->record[0] into the table.

Where row_data is the row as stored in the data area of a rows event. 
Thus:

a) unpacking of row_data happens at the time when row is written into 
 a table,

b) when unpacking (in step 4), only columns present in row_data are 
 overwritten - all other columns remain as they were found in the table.
 
Since all data needed for the above algorithm is stored inside 
Rows_log_event class, functions which locate and write rows are turned 
into methods of that class.

replace_record()     -> Rows_log_event::write_row()
find_and_fetch_row() -> Rows_log_event::find_row()

Both methods take row data from event's data buffer - the row being 
processed is pointed by m_curr_row. They unpack the data as needed into 
table's record buffers record[0] or record[1]. When row is unpacked, 
m_curr_row_end is set to point at next row in the data buffer.

Other changes introduced in this changeset:

- Change signature of unpack_row(): don't report errors and don't
setup table's rw_set here. Errors can happen only when setting default 
values in prepare_record() function and are detected there.
 
- In Rows_log_event and derived classes, don't pass arguments to
the execution primitives (do_...() member functions) but use class
members instead.

- Move old row handling code into log_event_old.cc to be used by 
*_rows_log_event_old classes.

Also, a new test rpl_ndb_2other is added which tests basic replication 
from master using ndb tables to slave storing the same tables using 
(possibly) different engine (myisam,innodb).
  
Test is based on existing tests rpl_ndb_2myisam and rpl_ndb_2innodb. 
However, these tests doesn't work for various reasons and currently are 
disabled (see BUG#19227).
  
The new test differs from the ones it is based on as follows:
  
1. Single test tests replication with different storage engines on slave 
(myisam, innodb, ndb).
  
2. Include file extra/rpl_tests/rpl_ndb_2multi_eng.test containing 
original tests is replaced by extra/rpl_tests/rpl_ndb_2multi_basic.test 
which doesn't contain tests using partitioned tables as these don't work 
currently. Instead, it tests replication to a slave which has more or 
less columns than master.
  
3. Include file include/rpl_multi_engine3.inc is replaced with 
include/rpl_multi_engine2.inc. The later differs by performing slightly 
different operations (updating more than one row in the table) and 
clearing table with "TRUNCATE TABLE" statement instead of "DELETE FROM" 
as replication of "DELETE" doesn't work well in this setting.
  
4. Slave must use option --log-slave-updates=0 as otherwise execution of 
replication events generated by ndb fails if table uses a different 
storage engine on slave (see BUG#29569).

Bug #16979: AUTO_INC lock in InnoDB works a table level lock
  Add a table level counter that tracks the number of AUTOINC locks that are
  pending and/or granted on a table. We peek at this value to determine whether
  a transaction doing a simple INSERT in innodb_autoinc_lock_mode = 1, needs to
  acquire the AUTOINC lock or not. This change is related to Bug# 16979.
Bug #27950: Duplicate entry error in auto-inc after mysqld restart
  We check whether the AUTOINC sub-system has been initialized (first) by
  holding the AUTOINC mutex and if initialization is required then we
  initialize using our normal procedure.

Bug #16979: AUTO_INC lock in InnoDB works a table level lock
  - this is a major change in InnoDB auto-inc handling.
Bug #27950: Duplicate entry error in auto-inc after mysqld restart
  - Init AUTOINC from delete_row().
Bug #28781: InnoDB increments auto-increment value incorrectly with ON DUPLICATE KEY UPDATE
  - Use value specified by MySQL, in update_row().
