Here we go.

I left the name at my suggestion pg_fsync_prepare instead of Tom's
prepare_for_fsync because it seemed more consistend with the naming in the
rest of the file. Obviously feel free to adjust.

I personally think the fsync on the directory should be added to the stable
branches - other opinions?
If wanted I can prepare patches for that.
