7317834417 raft: increase term to 1 before append initial entries 
Because the term of new raft is 0, it is weird to have term-1 committed
entries in the log.

ea4d645a83 raft: Ignore redundant addNode calls. 
This avoids clobbering any state when bootstrapping entries are
applied twice.

3d91faf85a Pre-apply the bootstrapping ConfChange entries. 
This eliminates the need to fake an ApplyConfChange call before Campaign
in tests.

Fixes #1856.

6409a8bf0d raft: filter out messages from unknow sender. 
If we cannot find the `m.from` from current peers in the raft and it is a response
message, we should filter it out or raft panics. We are not targetting to avoid
malicious peers.

It has to be done in the raft node layer syncchronously. Although we can check
it at the application layer asynchronously, but after the checking and before
the message going into raft, the raft state machine might make progress and
unfortunately remove the `m.from` peer.

raft: return 0 for term of compacted index

34a468de36 raft: return 0 for term of compacted index 
It is necessary to make this check because of the following case:

1. memory storage contains ents from index 0 to 50, and unstable has
ents from index 50 to 60.
2. raft receives an incoming snapshot with index 100.
3. raft restores its unstable to 100, but has not applied snapshot on memory storage.
4. raft receives an out-dated MsgApp from index 60.
5. raft finds the term of index 60 to check the match.
6. raft asks memory storage about the term of index 60 after it failed to get
it from unstable.
7. memory storage panics because it knows nothing about index 60.

b3841afcc3 raft: do not restore snapshot if local raft has longer matching history 
Raft should not restore the snapshot if it has longer matching history.
Or restoring snapshot might remove the matched entries.

551a56fb98 raft: not call stableTo for restored snapshot 
Stable has been set when restoring the snapshot in raftlog, so we don't need
to set it after advance.
