raft: update unstable when calling stableTo with 0
...
It should update unstable in this case because it may happen that raft
only writes entry 0 into stable storage.

raft: remove raftLog.resetUnstable and resetNextEnts
...
These methods are no longer used outside of tests and are redundant with
the new stableTo and appliedTo methods.

*: add a Advance interface to raft.Node
...
Node set the applied to committed right after it sends out Ready to application. This is not
correct since the application has not actually applied the entries at that point. We add a
Advance interface to Node. Application needs to call Advance to tell raft Node its progress.
Also this change can avoid unnecessary copying when application is still applying entires but
there are more entries to be applied.

compact MUST happen on entries that have been applied, or
1. it may screw up the log by setting wrong commitIndex
2. discard unapplied entries
