+supporting missing values and with most datastructures residing off-heap.
+Added "Memory" docvalues format that works entirely in heap, and "Disk"
+loads no datastructures into RAM. Both of these also support missing values.

+Lucene ships now with stateless singletons for per field and global reuse.
+Legacy code can still instantiate the deprecated implementation classes,
