d7db12ad77 ITS#7377 Always notice env error on txn startup.

060b63a58d Cleanup: Drop !mt_dbxs hack, use MDB_TXN_FINISHED 2015-07-19 21:31:54 +02:00
Hallvard Furuseth
3e301ec400 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.

b6973a3324 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).

9574b65648 Fix mdb_mutex_t, add mdb_mutexref_t, drop MDB_MUTEX(). 
Fixes the types of Windows HANDLEs, they became HANDLE*.
MDB_MUTEX() took a magic r/w arg which it's nice to get rid of.
