    catopen(3): Fix race condition
    
    The current code uses a rwlock to protect the cached list, which
    in turn holds a list of catentry objects, and increments reference
    count while holding only read lock.  Fix this by converting the
    reference counter to use atomic operations.
    
    Also improve the cleanups of memory allocations.
