mvcc: restore unsynced watchers 
In case syncWatchersLoop() starts before Restore() is called,
watchers already added by that moment are moved to s.synced by the loop.
However, there is a broken logic that moves watchers from s.synced
to s.uncyned without setting keyWatchers of the watcherGroup.
Eventually syncWatchers() fails to pickup those watchers from s.unsynced
and no events are sent to the watchers, because newWatcherBatch() called
in the function uses wg.watcherSetByKey() internally that requires
a proper keyWatchers value.

93225ebafc mvcc: fix rev inconsistency 
Try:

./etcdctl put foo bar
./etcdctl del foo
./etcdctl compact 3

restart etcd

./etcdctl get foo
mvcc: required revision has been compacted

The error is unexpected when range over the head revision.

Internally, we incorrectly set current revision smaller than the
compacted revision when we remove all keys around compacted revision.

This commit fixes the issue by recovering the current revision at least
to compacted revision.

bd62b0a646 mvcc: attach keys to leases after recover all state 
The previous logic is wrong. When we have hisotry like Put(foo, bar, lease1),
and Put(foo, bar, lease2), we will end up with attaching foo to two leases 1 and
2. Similar things can happen for deattach by clearing the lease of a key.

Now we try to fix this by starting to attach leases at the end of the recovery.
We use a map to keep the last lease attachment state.

dced92f8bd *: support watch with filters 
Now user can filter events with types. The API is also extensible.
It might make sense for the proxy to filter out events based on
more expensive/customized filter.

dbc7c2cf4e backend: reuse timer in run(). 
Benchmarks:

```
import (
	"testing"
	"time"
)

func BenchmarkTimeAfter(b *testing.B) {
	b.ReportAllocs()
	for n := 0; n < b.N; n++ {
		select {
		case <- time.After(1 * time.Millisecond):
		}
	}
}

func BenchmarkTimerReset(b *testing.B) {
	b.ReportAllocs()
	t := time.NewTimer(1 * time.Millisecond)
	for n := 0; n < b.N; n++ {
		select {
		case <- t.C:
		}
		t.Reset(1 * time.Millisecond)
	}
}
```

Running reveals that each loop results in 3 allocs:

```
BenchmarkTimeAfter-4 	    2000	   1112134 ns/op	     192 B/op	       3 allocs/op
BenchmarkTimerReset-4	    2000	   1109774 ns/op	       0 B/op	       0 allocs/op

f57b4eb46d mvcc: don't cancel watcher if stream is already closed 
Close() already cancels all the watchers but doesn't bother to clear out
the bookkeeping maps so Cancel() may try to cancel twice.

cfb3f96c2b mvcc: tighten up watcher cancelation and revision handling 
Makes w.cur into w.minrev, the minimum revision for the next update, and
retries cancelation if the watcher isn't found (because it's being processed
by moveVictims).
