Details :
 - During server initialization, when boolean values 1/true OR 0/false
   are given, then they were accpected but if on/off were given then
   they were being considered wrong.

Reason :
 - During server initialization, while checking for the valid values
   for boolean parameters, only 1/true AND 0/false were being checked.

Solution :
 - Added code to check for On/Off and if found, make them valid values.

 Test case innodb_file_per_table_basic.test is already there to check
 this parameter. So no new test case required. I just added
 --innodb_file_per_table in master.opt files with value On (Default) 
 so that at startup this fix could be verified.
