    Attachment: HBASE-1947.patch

Simple patch that adds new methods to do the checks. I tried it on my machine and it compacted the 20 store files I had in ROOT right away.

> Since we don't compact on open and close of regions, all regions that have edits will do a flush when the cluster is stopped so that if you do it a couple of times in a row it's easy to get more than 10 store files and it won't be compacted until the next day. On open, we should check that number and compact if needed.
