Thirunarayanan Balathandayuthapani 07ba5560da Bug #20989615 INNODB AUTO_INCREMENT PRODUCES SAME VALUE TWICE
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.
