ceph: support copy_file_range file operation
This commit implements support for the copy_file_range syscall in cephfs.
It is implemented using the RADOS 'copy-from' operation, which allows to
do a remote object copy, without the need to download/upload data from/to
the OSDs.
Some manual copy may however be required if the source/destination file
offsets aren't object aligned or if the copy length is smaller than the
object size.
