There are separate flags DBUG_OFF for disabling the DBUG facility
and ENABLED_DEBUG_SYNC for enabling the DEBUG_SYNC facility.
Let us allow debug builds without DEBUG_SYNC.
Note: For CMAKE_BUILD_TYPE=Debug, CMakeLists.txt will continue to
define ENABLED_DEBUG_SYNC.
Problem:
=======
Autoincrement value gives duplicate values because of the following reasons.
(1) In InnoDB handler function, current autoincrement value is not changed
based on newly set auto_increment_increment or auto_increment_offset variable.
(2) Handler function does the rounding logic and changes the current
autoincrement value and InnoDB doesn't aware of the change in current
autoincrement value.
Solution:
========
Fix the problem(1), InnoDB always respect the auto_increment_increment
and auto_increment_offset value in case of current autoincrement value.
By fixing the problem (2), handler layer won't change any current
autoincrement value.
