Removed the no longer used memberRemoveInterruptably() method. This method used to be used in AbstractQuorum.terminate(). It was probably removed from use when we did the ZK disconnect refactor.

Author: martyncutcher

Log Message:
-----------
Add service specific methods for doPipelineRemove/doWithdrawVote.. etc to allow the forcing of zookeeper state changes by "controlling" services, where previously global zookeeper state changes were only triggered by the effected service. This has been introduced specifically to support the forced removal of a service as a result of a sudden death or wire pull.

Add javadoc for possible metaBits reservation in order to stress allocation methods.
Previously a method had been added to ensure reservation but because this had to be integrated with the commit protocol it felt like the wrong approach and was not committed once the original problem that prompted its development was solved.

Log Message:
-----------
Renamed JoinType NotExists as Minus, to reflect actual use, and patched up implementation of BOpContext.bind().
Added about a dozen tests for MINUS and fixed issues in various optimizers related to these tests.
Added some lifting of badly formed MINUS groups into subqueries.
Provided inline style for Data Driven SPARQL Test Cases.
Added new Optimizer for MINUS { {} UNION {} }
Substantial refactoring of StaticAnalysis using a strategy pattern to eliminate code duplication.
