26abd25cd3 mvcc/backend: hold 'readTx.Lock' until completing bolt.Tx reset 
Fix https://github.com/coreos/etcd/issues/7526.

When resetting `bolt.Tx` in `defrag` and `batchTxBuffered.commit`
operation, we do not hold `readTx` lock, so the inflight range
requests can trigger panic in `mvcc.Range` paths. This fixes by
moving mutexes out and hold it while resetting the `readTx`.

33acbb694b mvcc: txns and r/w views 
Clean-up of the mvcc interfaces to use txn interfaces instead of an id.

Adds support for concurrent read-only mvcc transactions.

8d438c2939 backend: readtx 
ReadTxs are designed for read-only accesses to the backend using a
read-only boltDB transaction. Since BatchTx's are long-running
transactions, all writes to BatchTx will writeback to ReadTx, overlaying
the base read-only transaction.

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
```
