The existing CPUSet type is a fixed-size array limited to 1024 CPUs, which makes it problematic to use for large systems (such as Google's X4 instances with 1440 and 1920 vCPUs), see e.g. https://github.com/opencontainers/runc/issues/5023. Introduce CPUSetDynamic type and NewCPUSet constructor to support large systems. The bit-managing routines (set/clear/isset/fill/count) are separated and reused. Add variants of SchedGetaffinity, SchedSetaffinity and SetMemPolicy that accept the new type. Amend the documentation for CPUSet. Amend the existing TestSchedSetaffinity to: - test set.Fill; - use t.Cleanup to restore the affinity. Add tests for new functionality (mostly a copy of existing tests). This is an alternative to CL 727540 / CL 727541.
