This is 4/9 for https://github.com/ReOpen/ReOpenLDAP/issues/1
and https://github.com/ReOpen/ReOpenLDAP/issues/2

Here a lot of changes:
 - deleted a secondary DSYNC-mode file descriptor;
 - deleted a pointers to meta-pages and toggle-selection of ones;
 - removed MDB_FDATASYNC_WORKS/FDATASYNC_MAYBE_BROKEN stuff;
 - reworked use of fdatasync/fsync for safety without performance degradation;
 - txn-to-meta updating moved info mdb_txn_commit();
 - removed mdb_env_write_meta();
 - rewrited mdb_env_sync0() for clarify;

0ac9ba6472 lmdb: ITS#8117 better fix. 
LY: This is not required for ReOpenLDAP, because it
is not such issues related to int/long in cmp/dcmp.
But let be more close to origin's sources.

Origin: Don't change mc_dbx because we would need
to undo the change if the txn aborts. Make the fix
(for get) match existing code for put.
