Completes the work of removing the weirdness around transaction
boundaries in the storage engine API.

* Transactional storage engines are now all explicitly notified
  of the start of a new "normal" transaction in the new PSE API
  method plugin::TransactionalStorageEngine::doStartTransaction()
  This new method takes a start_transaction_option_t as one of its
  parameters, and passing this option allows the storage engine
  API to cleanly signal the start of a consistent snapshot (and in
  the future additional transaction attributes). This meant the
  removal of the old start_consistent_snapshot() method.

* The TransactionServices component now fully manages the transaction
  boundaries, notification of transaction boundaries to participating
  resource managers (transactional storage engines)

Adds a simple test case (to be expanded with future XA work) for
transaction behaviour.

Automates registration of statement transaction resources. No more need for storage engines to call TransactionServices::trans_register_ha(session, false, engine). yeah \o/
