Review request for hbase and stack.
Summary
-------
Moves all RPCs outside of the region writeLock - the writeLock is now only used
long enough to set the 'closing' flag. When we drop the lock any waiters will
see 'closing' upon acquiring the lock, and thus throw NSRE.
In the case that we abort the split, it will reopen the region as before.
Accessors will have gotten NSRE but will just come back to the same region
eventually.
This addresses bug HBASE-2964.

Testing
-------
YCSB testing on my cluster - it used to deadlock due to this bug within an
hour. I ran a 5 hour load test overnight and it worked OK.
Thanks,
Todd
