This patch fixes problem that LOAD DATA could use different
character sets when loading files on master and on slave sides:
- Adding replication of thd->variables.collation_database
- Adding optional character set clause into LOAD DATA

Note, the second way, with explicit CHARACTER SET clause
should be the recommended way to load data using an alternative
character set.
The old way, using "SET @@character_set_database=xxx" should be
gradually depricated.

duplicate key entries on slave" (two concurrrent connections doing
multi-row INSERT DELAYED to insert into an auto_increment column,
caused replication slave to stop with "duplicate key error" (and
binlog was wrong)), and BUG#26116 "If multi-row INSERT
DELAYED has errors, statement-based binlogging breaks" (the binlog
was not accounting for all rows inserted, or slave could stop).
The fix is that: if (statement-based) binlogging is on, a multi-row
INSERT DELAYED is silently converted to a non-delayed INSERT.
Note: it is not possible to test BUG#25507 in 5.0 (requires mysqlslap),
so it is tested only in the changeset for 5.1. However, BUG#26116
is tested here, and the fix for BUG#25507 is the same code change.

"INSERT... ON DUPLICATE KEY UPDATE skips auto_increment values".
When in an INSERT ON DUPLICATE KEY UPDATE, using
an autoincrement column, we inserted some autogenerated values and
also updated some rows, some autogenerated values were not used
(for example, even if 10 was the largest autoinc value in the table
at the start of the statement, 12 could be the first autogenerated
value inserted by the statement, instead of 11). One autogenerated
value was lost per updated row. Led to exhausting the range of the
autoincrement column faster.
Bug introduced by fix of BUG#20188; present since 5.0.24 and 5.1.12.
This bug breaks replication from a pre-5.0.24 master.
But the present bugfix, as it makes INSERT ON DUP KEY UPDATE
behave like pre-5.0.24, breaks replication from a [5.0.24,5.0.34]
master to a fixed (5.0.36) slave! To warn users against this when
they upgrade their slave, as agreed with the support team, we add
code for a fixed slave to detect that it is connected to a buggy
master in a situation (INSERT ON DUP KEY UPDATE into autoinc column)
likely to break replication, in which case it cannot replicate so
stops and prints a message to the slave's error log and to SHOW SLAVE
STATUS.
For 5.0.36->[5.0.24,5.0.34] replication we cannot warn as master
does not know the slave's version (but we always recommended to users
to have slave at least as new as master).
As agreed with support, I'll also ask for an alert to be put into
the MySQL Network Monitoring and Advisory Service.


mysql-test/r/rpl_insert_id.result:
  results to check the bugfix; without the bugfix, you would see, in
  master and slave:
  "3,2" instead of "2,2" for the INSERT VALUES testcase,
  "11,6,..." instead of "6,6,..." for the INSERT SELECT testcase.
mysql-test/t/rpl_insert_id.test:
  testing that BUG#24432 is fixed
sql/log_event.cc:
  A trick to force the master to pretend it is old and features BUG#24432.
  To do fast lookups in the list of known bugs by version, we compute
  the 3 X.Y.Z numbers from the master's version string and cache that
  into a new member Format_description_log_event::server_version_split.
  We do this computation in the event's two constructors.
  A simple prevention against buffer overrun when reading the master's
  version from a binlog event (assume the event is corrupted on disk,
  and so the version string on disk is longer than ST_SERVER_VER_LEN
  (50), then we would not get a closing 0 at the end of the class member.
sql/log_event.h:
  new member to hold the "split server version" (3 numbers X.Y.Z),
  and a method to compute this from the version string.
sql/slave.cc:
  a function which tells, based on master's version (as found
  in the Format_description event in the relay log being executed),
  if master can have a certain bug. This function uses a list of
  bug_id / first_version_with_bug / first_version_with_fix.
  If the test is positive, a short error message is put into SHOW SLAVE
  STATUS, and a verbose message is put into the slave's error log.
  The caller is expected to stop the slave in this case.
sql/slave.h:
  new function to test if the replication master has a bug
sql/sql_insert.cc:
  Fix for BUG#24432:t he reason was a misplaced restore_auto_increment() 
  (misplaced when fixing BUG#20188). Indeed, when updating the row,
  it is clear that the autogenerated auto_increment value will not be
  used for this row (and if by "chance" the autoinc value present
  in the updated row is >= to the not used autogenerated value,
  adjust_next_insert_id_after_explicit_value() will fix next_insert_id).
  We also add code for a fixed slave to detect that it is connected to
  a buggy master (in which case it cannot replicate so stops).
mysql-test/r/rpl_known_bugs_detection.result:
  see that SHOW SLAVE STATUS prints information that slave found a bug
  in master, and does not execute the dangerous event (table stays
  empty).
mysql-test/t/rpl_known_bugs_detection-master.opt:
  pass debug symbol to make the master pretend it has BUG#24432
mysql-test/t/rpl_known_bugs_detection.test:

Problem: "Data truncated" warning was incorrectly generated
when storing a Japanese character encoded in utf8
into a cp932 column.
Reason: Incorrect wrong warning condition
compared the original length of the character in bytes
(which is 3 in utf8) to the converted length of the
character in bytes (which is 2 in cp932).
Fix: use "how many bytes were scanned from input" instead
of "how many bytes were put to the column" in the condition.

This patch deprecates the replication startup options in the configuration
file and on the command line. The options deprecated include:

MASTER_HOST, MASTER_USER, MASTER_PASSWORD, MASTER_PORT, MASTER_CONNECT_RETRY,
MASTER_SSL, MASTER_SSL_CA, MASTER_SSL_CAPATH, MASTER_SSL_CERT, MASTER_SSL_KEY,
and MASTER_SSL_CIPHER

The code is designed to print the warning message once.


sql/mysql_priv.h:
  BUG#21490 - No warning issued for deprecated replication parameters
  This patch modifies the WARN_DEPRECATED macro to permit displaying a deprecated 
  warning to the user at startup when the replication startup options are detected.
  It displays the same messae as the original version of the macro but allows the 
  macro to be called before a thread is created and the ER() macro is defined.

of untouched rows in full table scans".

SELECT ... FOR UPDATE/LOCK IN SHARE MODE statements as well as
UPDATE/DELETE statements which were executed using full table
scan were not releasing locks on rows which didn't satisfy
WHERE condition.
This bug surfaced in 5.0 and affected NDB tables. (InnoDB tables
intentionally don't support such unlocking in default mode).

This problem occured because code implementing join didn't call
handler::unlock_row() for rows which didn't satisfy part of condition
attached to this particular table/level of nested loop. So we solve
the problem adding this call.
Note that we already had this call in place in 4.1 but it was lost
(actually not quite correctly placed) when we have introduced nested 
joins.

Also note that additional QA should be requested once this patch is
pushed as interaction between handler::unlock_row() and many recent
MySQL features such as subqueries, unions, views is not tested enough.


mysql-test/r/ndb_lock.result:
  Enabled back part of the test that covers bug #20390 "SELECT FOR
  UPDATE does not release locks of untouched rows in full table scans".
  Adjusted test in such way that it now covers both execution paths
  in which we unlock non-matching rows inspected during table scan.
mysql-test/t/ndb_lock.test:
  Enabled back part of the test that covers bug #20390 "SELECT FOR

  Adjusted test in such way that it now covers both execution paths

sql/sql_select.cc:
  evaluate_join_record() should call handler::unlock_row() for records
  which don't satisfy condition which was pushed-down to this table/level
  of nested loop.
  We just put back the thing that we already have in 4.1 and which was lost
  when we have introduced nested joins.
