06c69d2ed6 Buffer updates per-transaction rather than per-update. If lots of 
updates happen within a single transaction, there was a lot of wasted
encode/decode overhead due to segment merges.  This code buffers
updates in memory and writes out larger level-0 segments.  It only
works when documents are presented in ascending order by docid.
Comparing a test set running 100 documents per transaction, the total
runtime is cut almost in half. (CVS 3751)
