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.

ceph: allow preferred osd to be get/set via layout ioctl
There is certainly no reason not to report this.
The only real downside to allowing the user to set it is that you don't
get default values by zeroing the layout struct (the default is -1).
