[PATCH v2, resend 2/6] kernel/cpu.c: change type of cpu_possible_bits and friends

Change cpu_possible_bits and friends (online, present, active) from being bitmaps that happen to have the right size to actually being struct cpumasks. Also rename them to __cpu_xyz_mask. This is mostly a small cleanup in preparation for exporting them and, eventually, eliminating the extra
