libceph: introduce and start using oid abstraction
In preparation for tiering support, which would require having two (base and target) object names for each osd request and also copying those names around, introduce struct ceph_object_id (oid) and a couple helpers to facilitate those copies and encapsulate the fact that object name is not necessarily a NUL-terminated string.
