 Make txn->abort work without bombing out for {{{test_txn_abort5}}} one case. Fixes #431.
 Start writing {{{test_txn_abort6}}}.   Addresses #443.
 Try to write a test for #399 and #400, but haven't managed to reproduce the problem.  Addresses #399, #400.
 Write a test for #332.  Addresses #332.

git-svn-id: file:///svn/tokudb@2296 c7de825b-a66e-492c-adef-691d508d4ae1

Separates out error handling and ephemeral locking. 
However, it fails a few tests.

Partial implementation of nested transactions for locking purposes.
The actual txn (child/grandchild/etc) does all the work,
but for locking purposes we only use the parent (oldest ancestor).
This should work as expected (with possibly some extra lock overhead)
as long as no node has two active (non-aborted non-committed) children
simultaneously.

If a node has two children, they are supposed to be able to conflict
with each other (and deadlock/etc).  We are not providing this
conflict behavior between siblings.

We do support arbitrarily deep nested txns, so long as it is
a linked list instead of a general tree.

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.

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