Don't create compound file for large segments by default

Key: LUCENE-2773
URL: https://issues.apache.org/jira/browse/LUCENE-2773
Project: Lucene - Java
Issue Type: Improvement
Components: Index
Reporter: Michael McCandless
Assignee: Michael McCandless
Fix For: 3.1, 4.0
Spinoff from LUCENE-2762.
CFS is useful for keeping the open file count down. But, it costs
some added time during indexing to build, and also ties up temporary
disk space, causing eg a large spike on the final merge of an
optimize.
Since MergePolicy dictates which segments should be CFS, we can
change it to only build CFS for "smallish" merges.
I think we should also set a maxMergeMB by default so that very large
merges aren't done.
