    ocfs2: Change the recovery map to an array of node numbers. · 553abd04
    Joel Becker authored
    The old recovery map was a bitmap of node numbers.  This was sufficient
    for the maximum node number of 254.  Going forward, we want node numbers
    to be UINT32.  Thus, we need a new recovery map.
    
    Note that we can't keep track of slots here.  We must write down the
    node number to recovery *before* we get the locks needed to convert a
    node number into a slot number.
    
    The recovery map is now an array of unsigned ints, max_slots in size.
    It moves to journal.c with the rest of recovery.
    
    Because it needs to be initialized, we move all of recovery initialization
    into a new function, ocfs2_recovery_init().  This actually cleans up
    ocfs2_initialize_super() a little as well.  Following on, recovery cleaup
    becomes part of ocfs2_recovery_exit().
    
    A number of node map functions are rendered obsolete and are removed.
    
    Finally, waiting on recovery is wrapped in a function rather than naked
    checks on the recovery_event.  This is a cleanup from Mark.
