d6b3c6f710 lmdb: ITS#7377 Always notice env error on txn startup. 
Move the check to the end of txn startup.  Catches env
breakage which happens while the new txn waits for a lock.

342d56977f lmdb: Catch most uses of finished/parent txns. 
* Add MDB_TXN_FINISHED, MDB_TXN_HAS_CHILD, MDB_TXN_BLOCKED.
* Clear mt_numdbs in writers, for TXN_DBI_EXIST() to catch.
  We already do in readers.

e3c8fa8eba lmdb: Move code into mdb_txn_end(). Was mdb_txn_reset0. 
Side effects:
* Clean txn up a bit even before freeing it.
* Tweak DEBUG output at txn end. Add DEBUG after commit(writer).

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.
