DB2 FOR LUW / DB2FORLUW / B10 - DB2

In environments with services that have path to binary 
(including arguments) longer than 260 characters, memory 
corruption occurs during install, causing unpredictable 
behaviour. 
Since a loop counter is likely to be overwritten (since both the 
string buffer that gets overflown and loop counter are both on 
stack), we are likely to iterate way farther than we initially 
intend to, resulting in Access Violation (SEGFAULT equivalent). 
 
This is caused by using strcpy instead of ossStrNCopy in 
TaskStartAutomaticDB2Services::CheckForAutoDB2ServiceAndStart 
 
The fix to this changes strcpy to ossStrNCopy. 
An additional check for null pointer will also be added to 
TaskStartAutomaticDB2Services::CheckForAutoDB2ServiceAndStart
