  BUG#10831 ndb mgmd LogDestination maxfiles does not rotate logs properly

    my_stat returns NULL on failure, not non-zero.
    
    i.e. exactly the opposite of stat(2).
    
    providing confusion for unix programmers, who expect errors to be non-zero.
    
    Clean up File_class::exists(char*) to use the my_stat interface properly.

# This is a BitKeeper patch.  What follows are the unified diffs for the
# set of deltas contained in the patch.  The rest of the patch, the part
# that BitKeeper cares about, is below these diffs.
