    bitset: expand bit index type to `long`
    
    An upcoming patch to use the bitset macros for tracking vm page
    dump information could conceivably need more than INT_MAX bits.
    Expand the bit type to long so that the extra range is available
    on 64-bit platforms where it would most likely be needed.
    
    CPUSET_COUNT and DOMAINSET_COUNT are also modified to remain of
    type `int`.
