JENA-1542: Integrate Lucene index in transaction lifecycle (TDB1, TDB2).
Includes the fix for JENA-1302.
Integrate a lucene text index into the transaction systems for TDB1 and
DBOE/TDB2. This way, the prepare/commit for Lucene happens during database
commit and the synchronization dance (JENA-1302) does not happen.
JENA-1302 only effects TDB1, not TDB2. Only TDB1 has a commit queue that
can build up under load and need to be flushed, which in turn causes a thread
to take the exclusive lock and so cause the JENA-1302 lockup.

JENA-1542, JENA-1302: Integrate jena-text with TDB1 and TDB2 transactions.
----
> Allow addition of transaction components after initial setup.
> -------------------------------------------------------------
>
> Key: JENA-1542
> URL: https://issues.apache.org/jira/browse/JENA-1542
> Project: Apache Jena
> Issue Type: Improvement
> Components: TDB, TDB2
> Affects Versions: Jena 3.7.0
> Reporter: Andy Seaborne
> Assignee: Andy Seaborne
> Priority: Major
>
> Currently:
> * TDB1: the set of {{TransactionLifecycle}} components is fixed
> * TDB2: the set of {{TransactionComponents}} is frozen during creation of a
> dataset.
> In order to be able to add a text index into the transaction handling, allow
> new items to be added (carefully) into the transaction subsystem for a
> dataset.
> This is necessary for JENA-1302.
