New Search Indexing Support

Proposal for a faster JDT index bug 481796.
Plan is to introduce a global index that holds semantic information rather than filename mappings, supports reliable error detection, and is extensible enough to replace all current indexes and caches. It will support most common JDT operations without the need to ever open a .jar file or perform an exhaustive search. The design document is available here The Indexer is not yet adopted across all JDT features. At the moment, this new Indexer is disabled by default. bug 515496
