This patch adds code to the binlog calls for replication of the
CREATE, DROP, and UPDATE event commands. An extra gate was added 
to ensure a query with length 0 is not binlogged. This corrects 
the problem of events_scheduling and rpl_events failing on some
build machines.


sql/events.cc:
  WL#3629 - Replication of Invocation and Invoked Features
  
  This patch adds code to the binlog calls for replication of the
  CREATE, DROP, and UPDATE event commands. An extra gate was added 
  to ensure a query with length 0 is not binlogged. This corrects 
  problems found when the patch for this worklog was pushed.

into  mysql_cab_desk.:C:/source/c++/mysql-5.1_WL_3629_test

    
This patch changes test to remove Windows-specific limitations and potential
rounding errors in the calculation of a UDF.

Also corrects a minor merge conflict.


mysql-test/include/rpl_udf.inc:
  WL#3629 - Replication of Invocation and Invoked Features
      
  This patch changes test to remove Windows-specific results by replacing the
  library name in the SELECT from mysql.func to "UDF_LIB" to allow for the 
  differences in platform (.so vs .dll).
  
  The patch also changes the function body of myfuncsql_double to a calculation
  that does not result in potential rounding errors from the test data.
mysql-test/r/rpl_udf.result:
  WL#3629 - Replication of Invocation and Invoked Features
      
  This patch changes the result file for the test to match the new expected
  values for the SELECT from mysql.func and the return of myfuncsql_double.
scripts/mysql_system_tables_fix.sql:
  WL#3629 - Replication of Invocation and Invoked Features
      
  This patch corrects a merge error encountered in a previous merge. The
  column originator should be listed before time_zone in mysql.event.

Adding an event that can be used to denote that an incident occured
on the master. The event can be used to denote a gap in the replication
stream, but can also be used to denote other incidents.

In addition, the injector interface is extended with functions to
generate an incident event. The function will also rotate the binary
log after generating an incident event to get a fresh binary log.

This patch corrects errors that occurred in a local manual merge as a result
of updating the local repository and includes changes necessary to correct 
problems found during the recalculation of next execution of events in RBR.


mysql-test/include/rpl_events.inc:
  WL#3629 - Replication of Invocation and Invoked Features
  
  This patch changes the rpl_events test to be more comprehensive in catching
  errors as a result of RBR. Changes include clarification of SELECTs with
  WHERE clauses and synchronization with master and slave.
mysql-test/r/rpl_events.result:
  WL#3629 - Replication of Invocation and Invoked Features
  
  This patch changes the results for the rpl_events test to accomodate the changes
  in the test.
scripts/mysql_system_tables.sql:
  WL#3629 - Replication of Invocation and Invoked Features
  
  This patch adds the originator column and a new enum value to the mysql.event table.
  This change was necessary to accomodate changes as a result of other patches.
sql/event_data_objects.cc:
  WL#3629 - Replication of Invocation and Invoked Features
  
  This patch corrects an error in merging that occurred during manual merge.
  The status check was changed to include either ENABLED or DISABLED in the
  gate to change the status to SLAVESIDE_DISABLED for events replicated to 
  the slave.
  
  This patch also includes an update to correct a problem encountered during
  testing after the local merge. The update_timing_fields method is replicating
  the timing changes in RBR to the slave thereby over writing the change to the
  status column in the process. This code includes a check to turn off the next
  binlog event if in RBR.
sql/event_queue.cc:
  WL#3629 - Replication of Invocation and Invoked Features
  
  This patch corrects an error in merging that occurred during manual merge.
  The code was corrected to include both types of disabled status enums
  (DISABLED, SLAVESIDE_DISABLED) in the create_event and update_event methods.
sql/sql_show.cc:
  WL#3629 - Replication of Invocation and Invoked Features
  
  This patch corrects an error in merging that occurred during manual merge.
  It corrects the order in which the originator column appears in the show
  structures. The error caused incorrect output on SHOW EVENTS commands.

  Enabling test rpl_multi_engine.

rows event):

Adding a after image COLS bitmap to Update_rows_log_event (for telling
what columns that are present in the after image of each row update).

Also fixing case where Rows_log_event length was not correctly computed
(happened when the number of columns in a table was more than 251). 


mysql-test/r/rpl_row_inexist_tbl.result:
  Result change.
sql/log_event.cc:
  Extending Rows_log_event with two new fields: m_bitbuf_ai and m_cols_ai.  These fields are only used for the Update_rows_log_event.
  Adding implementation of Update_rows_log_event destructor.
  Using new after image fields inside the Update_rows_log_event.
  Factoring out common constructor bodies into Update_rows_log_event::init()
  function.
  
  Fixing case where length of Rows_log_event was not correctly computed (for
  tables with more than 251 columns).
sql/log_event.h:
  Moving implementation of Rows_log_event::get_data_size() into .cc file.
  Adding Update_rows_log_event constructor accepting both before image
  and after image COLS vector.
  Adding Update_rows_log_vector destructor.
  Adding fields m_bitbuf_ai and m_cols_ai to Rows_log_event.
  Fixing is_valid() to look at m_cols_ai as well.

- Fixing utf8_general_cs according to recent changes.
- Compiling utf8_general_cs in pentium-debug-max configuration
  to avoid these problems in the future.


BUILD/compile-pentium-debug-max:
  Enable compiling of experimental collations in compile-pentium-debug-max
config/ac-macros/character_sets.m4:
  Adding hidden flag --with-experimental-collations,
  not seen in "configure --help".
strings/ctype-utf8.c:
  Compilation failure changes:
  catching up with previous character set changes:
  - uni_plane is now not a global variables
  - adding new parameter into my_strnncollsp_utf8_cs
  - adding my_strnxfrm_len into MY_COLLATION_HANDLER 
    for utf8_general_cs

mysql-test/t/query_cache_sql_prepare.test:
  Auto merged

Fix: adding namespace reference into "mysql --xml" output,
to make it work similary to "mysqldump --xml".


client/mysql.cc:
  Adding namespace reference.
mysql-test/r/client_xml.result:
  Fixing test results

Problem: GROUP BY on empty ucs2 strings crashed server.
Reason: sometimes mi_unique_hash() is executed with
ptr=null and length=0, which means "empty string".
The branch of code handling UCS2 character set
was not safe against ptr=null and fell into and
endless loop even if length=0 because of poiter
arithmetic overflow.
Fix: adding special check for length=0 to avoid pointer arithmetic
overflow.


mysql-test/r/ctype_uca.result:
  Adding test case
mysql-test/t/ctype_uca.test:
  Adding test case
strings/ctype-uca.c:
  Fix my_uca_scanner_init_ucs2 to be safe against
  strings with length=0 and ptr=0.

storage/archive/ha_archive.cc:
  Auto merged

Centralized init logic for starting a scan. 


storage/archive/ha_archive.cc:
  Removed multiple execution logic
