Only uses lock tree if both txns and locking system are enabled.
If TXN only is enabled, it implies only one txn at a time: no lock tree needed.
If LOCK only is enabled, it implies no txns, therefore only ephemeral locks needed (lock tree not needed)
If neither are enabled, clearly lock tree is not needed.

Fixed some bugs in test_db_txn_locks
to port it over to BDB.

Bugfix with releasing locks/unlocking a transaction.

DBC->c_get (DB_SET)
and DB->put (DB_YESOVERWRITE) now perform locking
Secondary dbs not included (behavior unknown).

Several tests added for c_get (DB_SET) and DB->put(DB_YESOVERWRITE).

Lock tree only created if INIT_TXN is enabled during env creation.

Integrated lock tree into the transactions.
    Allocated on create
    unlocked on abort/commit
    transaction keeps track of which lock trees it owns locks in
Started working on integrating c_get functions.

Fixed tests to work with new locktree API.
