bug #27715: mysqld --character-sets-dir buffer overflow
bug ##26851: Mysql Client --pager Buffer Overflow
Using strmov() to copy an argument may cause overflow
if the argument's length is bigger than the buffer:
use strmake instead.
Also, we have to encrease the error message buffer size to fit
the longest message.
client/mysql.cc:
Fix for
bug #27715: mysqld --character-sets-dir buffer overflow
bug ##26851: Mysql Client --pager Buffer Overflow
- use strmake() instead of strmov() to avoid buffer overflow.

NO_AUTO_VALUE_ON_ZERO mode.
The table->auto_increment_field_not_null variable wasn't reset after
reading a row which may lead to inserting a wrong value to the auto-increment
field to the following row.
The table->auto_increment_field_not_null variable is reset now right after a
row is being written in the read_fixed_length() and the read_sep_field()
functions.
Removed wrong setting of the table->auto_increment_field_not_null variable in
the read_sep_field() function.

In certain cases AFTER UPDATE/DELETE triggers on NDB tables that referenced
subject table didn't see the results of operation which caused invocation
of those triggers. In other words AFTER trigger invoked as result of update
(or deletion) of particular row saw version of this row before update (or
deletion).
The problem occured because NDB handler in those cases postponed actual
update/delete operations to be able to perform them later as one batch.
This fix solves the problem by disabling this optimization for particular
operation if subject table has AFTER trigger for this operation defined.
To achieve this we introduce two new flags for handler::extra() method:
HA_EXTRA_DELETE_CANNOT_BATCH and HA_EXTRA_UPDATE_CANNOT_BATCH.
These are called if there exists AFTER DELETE/UPDATE triggers during a
statement that potentially can generate calls to delete_row()/update_row().
This includes multi_delete/multi_update statements as well as insert statements
that do delete/update as part of an ON DUPLICATE statement.
include/my_base.h:
Added HA_EXTRA_DELETE_CANNOT_BATCH and HA_EXTRA_UPDATE_CANNOT_BATCH to inform handler when batching of delete/update is not possible.

Bug #26242 UPDATE with subquery and triggers failing with cluster tables: Use HA_EXTRA_DELETE_CANNOT_BATCH and HA_EXTRA_UPDATE_CANNOT_BATCH to inform handler when batching of delete/update is not possible
sql/ha_ndbcluster.h:
Bug #26242 UPDATE with subquery and triggers failing with cluster tables: Added member variables for handling of HA_EXTRA_DELETE_CANNOT_BATCH and HA_EXTRA_UPDATE_CANNOT_BATCH to inform handler when batching of delete/update is not possible
sql/mysql_priv.h:
Added new method prepare_triggers_for_insert_stmt to check if batching of delete/update must be disallowed.
sql/sql_delete.cc:
Use HA_EXTRA_DELETE_CANNOT_BATCH to inform handler when batching of delete is not possible
sql/sql_insert.cc:
Added method prepare_triggers_for_insert_stmt to check if batching of delete/update must be dissallowed.
Use HA_EXTRA_DELETE_CANNOT_BATCH and HA_EXTRA_UPDATE_CANNOT_BATCH to inform handler
when batching of delete/update is not possible
sql/sql_load.cc:
Call prepare_triggers_for_insert_stmt to check if batching of delete/update must be dissallowed and
mark fields used by triggers for the insert statement.

Added has_triggers to support what particular triggers exist on a table.
sql/sql_update.cc:
Use HA_EXTRA_UPDATE_CANNOT_BATCH to inform handler when batching of update is not possible
IN/BETWEEN predicates in sorting expressions.
Wrong results may occur when the select list contains an expression
with IN/BETWEEN predicate that differs from a sorting expression by
an additional NOT only.
Added the method Item_func_opt_neg::eq to compare correctly expressions
containing [NOT] IN/BETWEEN.
The eq method inherited from the Item_func returns TRUE when comparing
'a IN (1,2)' with 'a NOT IN (1,2)' that is not, of course, correct.
