libceph: start using oloc abstraction
Instead of relying on pool fields in ceph_file_layout (for mapping) and ceph_pg (for enconding), start using ceph_object_locator (oloc) abstraction. Note that userspace oloc currently consists of pool, key, nspace and hash fields, while this one contains only a pool. This is OK, because at this point we only send (i.e. encode) olocs and never have to receive (i.e. decode) them. This makes keeping a copy of ceph_file_layout in every osd request unnecessary, so ceph_osd_request::r_file_layout field is nuked.
