8e1ebbb4a8 libmdb: Don't open datafile twice when not needed. 
If the database is opened with MDB_RDONLY or MDB_NOSYNC,
instead use the same file descriptor for me_mfd and me_fd.

Also factor out Windows/Unix error handling after open.

4a0b30499c libmdb: Do not use the MDB_txbody.mtb_txnid field. 
Get txn->mt_txnid from the meta page instead.  Otherwise it
and txn->mt_toggle could become inconsistent, since read-only
txns fetched both from MDB_txbody without mutex proteciton.

d3b9939e71 Clean up MAP_FAILED handling in mdb. 
Delay (MDB_txninfo*) cast to after comparing mmap() with MAP_FAILED.
Otherwise, if MAP_FAILED = (void*)-1 but MDB_txninfo requires stricter
alignment, the compiler could assume the result is never MAP_FAILED.

Also store NULL in env->(me_map, me_txns) after mmap failure.
