    HAWQ-241: Remove  MirroredLock related codes

    MirroredLock is no use in hawq because there is no segment mirroring, and it is not used
by master mirroring which uses xlog directly.
    
    The reason why we need to remove it is: in some scenarios the request order of this lock
and CheckpointStartLock may cause deadlock.
