Sage Weil 4918b6d140 ceph: add F_SYNC file flag to force sync (non-O_DIRECT) io ...

This allows us to force IO through the sync path which you normally only
get when multiple clients are reading/writing to the same file or by
mounting with -o sync.  Among other things, this lets test programs verify
correctness with a single mount.
