Deals with NULL transactions in a transaction environment for cursors.
Returns EINVAL (disallows NULL transaction cursors in txn environment.)
This may change later to auto-create transaction and commit it upon
cursor close.

git-svn-id: file:///svn/tokudb@2253 c7de825b-a66e-492c-adef-691d508d4ae1

Deals with NULL transactions in an INIT_TXN environment.
Does not deal with NULL txn cursors yet.
Also adds DB_AUTO_COMMIT

Restored the DUPSORT version of the tests for the lock txn test.

git-svn-id: file:///svn/tokudb@2211 c7de825b-a66e-492c-adef-691d508d4ae1

DB->get, DB->pget, DBC->c_get, DBC->c_pget almost done.
Remainder: associated dbs need DBC->c_del and DB->del to lock properly.
Rest is done.

Associated dbs (using any of the above calls) may get stuck half way due to locking.
We are not currently optimizing for them, but it will lock everything necessary
(Once DB->del and DB->c_del lock properly)

Some tests are written, but not all of them.

Currently test_db_txn_locks.c fails due to abort not working properly.

set the data and length to 0 for zero length things. dbt's with malloc flags are unchanged. closes #367

Make each rollback code take a list of arguments rather than a single logentry.  Makes it easier to notice that I've got unused variables.  Addresses #27.

is not supported by our cursor implementations.

Effectively eliminated 'non cursor' gets.
Internally (in brt) all gets were cursor gets already.
To save future locking code, and reduce complexity of ydb,
all DB->get calls use cursor gets as subfunctions.

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.
