BUG#21842 (Cluster fails to replicate to innodb or myisam with err 134 

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).


sql/log_event.cc:
  - Initialization of new Rows_log_event members.
  - Fixing some typos in documentation.
  
  In Rows_log_event::do_apply_event:
  - Set COMPLETE_ROWS_F flag (when master and slave have the same number of 
  columns and all colums are present in the row)
  - Move initialization of tables write/read sets here, outside the rows
  processing loop (and out of unpack_row() function).
  - Remove calls to do_prepare_row() - no longer needed.
  - Add code managing m_curr_row and m_curr_row_end pointers.
  
  - Change signatures of row processing methods of Rows_log_event and it
  descendants - now most arguments are taken from class members.
  - Remove do_prepare_row() methods which are no longer used.
  - The auto_afree_ptr template is moved to rpl_utility.h (so that it can
  be used in log_event_old.cc).
  - Removed copy_extra_fields() function - no longer used.
  
  In Rows_log_event::write_row (former replace_record):
  - The old code is moved to log_event_old.cc.
  - Use prepare_record() and non-destructive unpack_current_row() to fill record
  with data.
  - In case a record being inserted already exists on slave and row data is 
  incomplete use the record found and non-destructive unpack_current_row() to 
  combine new column values with existing ones.
  - More debug info added.
  
  In Rows_log_event::find_row (former find_and_fetch_row function):
  - The old code is moved to log_event_old.cc.
  - Unpacking of the row is moved here.
  - In case of search using PK, the key data is prepared here.
  - More debug info added.
  
  - Remove initialization of Rows_log_event::m_after_image buffer which is no
  longer used. 
  - Use new row unpacking methods in Update_rows_log_event::do_exec_row() to 
  create before and after image.
  
  Note: all existing code used by Rows_log_event::do_apply_event() has been moved
  to log_event_old.cc to be used by *_rows_log_event_old classes.
sql/log_event.h:
  - Add new COMPLETE_ROWS_F flag in Rows_log_event.
  - Add Rows_log_event members describing the row being processed.
  - Add a pointer to key buffer which is used in derived classes.
  - Add new methods: find__row(), write_row() and unpack_current_row().
  - Change signatures of do_...() methods (replace method arguments by
  class members).
  - Remove do_prepare_row() method which is no longer used.
  - Update method documentation.
  - Add Old_rows_log_event class, which contains the old row processing code, as
  a friend of Rows_log_event so that it can access all members of an event 
  instance.
sql/log_event_old.cc:
  Move here old implementation of Rows_log_event::do_apply_event() and 
  helper methods.
sql/log_event_old.h:
  - Define new class Old_rows_log_event encapsulating old version of
  Rows_log_event::do_apply_event() and the helper methods.
  - Add the Old_rows_log_event class as a base for *_old versions of RBR event
  classes, ensure that the old version of do_apply_event() is called.
  - For *_old classes, declare the helper methods used in the old version of
  do_apply_event().
sql/rpl_record.cc:
  - Make unpack_row non-destructive for columns not present in the row.
  - Don't fill read/write set here as it is done outside these functions.
  - Move initialization of a record with default values to a separate
  function prepare_record().
sql/rpl_record.h:
  - Change signature of unpack_row().
  - Declare function prepare_record().
sql/rpl_utility.cc:
  Make tabe_def::calc_field_size() a const method.
sql/rpl_utility.h:
  Make table_def::calc_field_size() a const method.
  
  Move auto_afree_ptr template here so that it can be re-used (currently
  in log_event.cc and log_event_old.cc). Similar with DBUG_PRINT_BITSET 
  macro.
mysql-test/extra/rpl_tests/rpl_ndb_2multi_basic.test:
  Modification of rpl_ndb_2multi_eng test. Tests with partitioned tables 
  are removed and a setup with slave having different number of columns 
  than master is added.
mysql-test/include/rpl_multi_engine2.inc:
  Modification of rpl_multi_engine3.inc which operates on more rows and
  replaces "DELETE FROM t1" with "TRUNCATE TABLE t1" as the first form
  doesn't replicate in NDB -> non-NDB setting (BUG#28538).
mysql-test/suite/rpl_ndb/r/rpl_ndb_2other.result:
  Results of the test.
mysql-test/suite/rpl_ndb/t/rpl_ndb_2other-slave.opt:
  Test options. --log-slave-updates=0 is compulsory as otherwise non-NDB 
  slave applying row events from NDB master will fail when trying to log
  them.
mysql-test/suite/rpl_ndb/t/rpl_ndb_2other.test:
  Test replication of NDB table to slave using other engine. The main test
  is in extra/rpl_tests/rpl_ndb_2multi_basic.test. It is included here
  several times with different settings of default storage engine on slave.

/**
Write the current row into event's table.
/*
Replace the provided record in the database.
The row is located in the row buffer, pointed by @c m_curr_row member.
Number of columns of the row is stored in @c m_width member (it can be
different from the number of columns in the table to which we insert).
Bitmap @c m_cols indicates which columns are present in the row. It is assumed
that event's table is already open and pointed by @c m_table.
SYNOPSIS
replace_record()
thd Thread context for writing the record.
table Table to which record should be written.
master_reclength
Offset to first column that is not present on the master,
alternatively the length of the record on the master
side.
If the same record already exists in the table it can be either overwritten
or an error is reported depending on the value of @c overwrite flag
(error reporting not yet implemented). Note that the matching record can be
different from the row we insert if we use primary keys to identify records in
the table.
RETURN VALUE
Error code on failure, 0 on success.
The row to be inserted can contain values only for selected columns. The
missing columns are filled with default values using @c prepare_record()
function. If a matching record is found in the table and @c overwritte is
true, the missing columns are taken from it.
DESCRIPTION
Similar to how it is done in mysql_insert(), we first try to do
a ha_write_row() and of that fails due to duplicated keys (or
indices), we do an ha_update_row() or a ha_delete_row() instead.

Shall we overwrite if the row already exists or signal
error (currently ignored).
@returns Error code on failure, 0 on success.
This method, if successful, sets @c m_curr_row_end pointer to point at the
next row in the rows buffer. This is done when unpacking the row to be
inserted.
@note If a matching record is found, it is either updated using
@c ha_update_row() or first deleted and then new record written.

copy field values and implement it for all Field subclasses. Use
this function to copy data from the found record to the record
