* Implement rangesets.Konstantin Belousov2019-02-201-0/+51
The data structure implements non-intersecting intervals over the [0, UINT64_MAX] range, and supports fast insert, predicated clearing of subrange, and lookup of an interval containing the specified address. Internally it is a pctrie over the interval start addresses. Implementation provides additional guarantees over the structure state in case of memory allocation failures.
