    BUG#39325 Server crash inside MYSQL_LOG::purge_first_log halts replicaiton
    
    The patch reverses the order of the purging and updating events for log and
    relay-log.info/index files respectively.
    
    This solves the problem of having holes caused by crashes happening between updating
    info/index files and purging logs.
    
    This patch also contains an aditional test case for testing the crashing before purge logs.
          
    NOTE1: This is a combined patch for BUG#38826 and BUG#39325. This patch is based on
    bugteam tree and takes into account reviewers suggestions.
    
    NOTE2: Merge from 5.0-bugteam
