libceph: primary_affinity infrastructure
Add primary_affinity infrastructure. primary_affinity values are stored in an max_osd-sized array, hanging off ceph_osdmap, similar to a osd_weight array. Introduce {get,set}_primary_affinity() helpers, primarily to return CEPH_OSD_DEFAULT_PRIMARY_AFFINITY when no affinity has been set and to abstract out osd_primary_affinity array allocation and initialization.
