Better SHOW PROCESSLIST for replication

Browse Source 
- When waiting for events, start time is now counted from start of wait
- Instead of having "Connect" as "Command" for all replication threads we
  now have:
  - Slave_IO for Slave thread reading relay log
  - Slave_SQL for slave executing SQL commands or distribution queries to
    Slave workers
  - Slave_worker for slave threads executin SQL commands in parallel replication
