> We have transformed HLog into an interface and created FSHLog to contain the current
implementation of HLog in HBASE-5937. In that patch, we have essentially exposed the public
methods, moved method implementations to FSHLog, created a factory for HLog, and moved static
methods to HLogUtil. 
> In this umbrella jira, the idea is to refine the WAL interface, making it not dependent
upon a file system as it is currently. The high-level idea is to revisit the methods in HLog
and HLogUtil and come up an interface that can accommodate other backends, such as BookKeeper.
Another major task here is to decide what to do with the splitter.
