stack updated HBASE-3291:
-------------------------

    Attachment: closing.txt

J-D also noticed that we are inconsistent in our synchronize of onlineRegions.  This patch addresses this and adds check on split for closing.

> J-D found this one testing.  He found that if a split comes in during shutdown of a regionserver, then the regionserver can stick open... and won't go down.
> We fixed a similar problem in the past where if balancer cut in during shutdown and assigned a regionserver an region during shutdown, we'd open it and it'd cause us again to stick open.  We fixed that by introducing the 'closing' state.
> Fix for the issue j-d found is to do closing check when onlining daughters.
