Review request for hive and John Sichi.


Summary
-------

Add support for generating index queries to support automatic usage of bitmap indexes. This required changing the interface to the IndexHandlers to support accepting queries on multiple indexes. The compact indexes were modified to use this new interface as well, although no functional changes were made to how they work. Only supports AND predicates right now, but it should be possibly to extend the BitmapQuery interface defined in this patch to easily support OR predicates as well. Currently benchmarking these changes on a test cluster.


This addresses bug HIVE-2036.

Testing
-------

Passes unit tests, additional testcase to test automatic bitmap indexing index_bitmap_auto.q was also added to the TestCliDriver suite. Currently benchmarking changes on a test cluster.

> HIVE-1644 will provide automatic usage of indexes, and HIVE-1803 adds bitmap index support.  The bitmap code will need to be extended after it is committed to enable automatic use of indexing.  Most work will be focused in the BitmapIndexHandler, which needs to generate the re-entrant QL index query.  There may also be significant work in the IndexPredicateAnalyzer to support predicates with OR's, instead of just AND's as it is currently.
