HBASE-544 Purge startUpdate from all internal code and test cases

Removes startUpdate calls from all but a few places. TestBatchUpdate and TestMultipleUpdates both stay the same, but TMU will be removed when startUpdate is. Parts of TBU will also be whacked when we remove the deprecated methods. HTable still has its startUpdate methods.

Changed the Incommon interface to remove the startUpdate, put, delete, and commit methods, and made a new commit(BatchUpdate).
