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.

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.

*: 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.

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

Close() already cancels all the watchers but doesn't bother to clear out
the bookkeeping maps so Cancel() may try to cancel twice.

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
