Remove O_FSYNC and associated macros. O_FSYNC was a pre-POSIX way of spelling O_SYNC, supported since commit 9d645fd84c3 for non-conforming operating systems of the time. It's not needed on any modern system. We can just use standard O_SYNC directly if it exists (= all targeted systems except Windows), and get rid of our OPEN_SYNC_FLAG macro. Similarly for standard O_DSYNC, we can just use that directly if it exists (= all targeted systems except DragonFlyBSD), and get rid of our OPEN_DATASYNC_FLAG macro. We still avoid choosing open_datasync as a default value for wal_sync_method if O_DSYNC has the same value as O_SYNC (= only OpenBSD), so there is no change in default behavior.
