Changes predating the PowerDNS fork (up to 2017):

• Fix unsafe threading behavior in benchmarks (bmatsuo#101)
• Update transactions no longer allocate MDB_val objects (bmatsuo#102)
• Txn.Renew no longer clears the Txn finalizer -- prevents resource leaks (bmatsuo#104)
• Txn.Pooled field added so that the Txn finalizer may work better with
  sync.Pool (bmatsuo#104 bmatsuo#105)
• Fixed a race in the Txn finalizer that could lead to a segfault (bmatsuo#105)
• Txn.RunOp method added so that it is possible for other packages to create
  other flavors of managed transactions from scratch (bmatsuo#105)
• Experimental package lmdbpool was added to make integration of lmdb and
  sync.Pool easier (bmatsuo#104 bmatsuo#105)
• Silence aggressive struct initializer warning from clang (bmatsuo#107)
• Improved documentation regarding long-running transactions and dead readers
  (bmatsuo#111)
