All index scans in Ndb are now bounded. 
The current behavior is only correct for values that JavaScript can 
properly compare.  For other values (e.g. strings using non-unicode
collations) there is still work to be done so that IndexBounds.js
can get encoded values rather than native values.
Change getIndexBounds() API so it might be used to evaluate 
a candidate index.
Fix so IndexBounds can store ranges for multiple indexes
